Sadly, the answer is not a direct one. Designing Your Life tries to offer another view to the problem. This book is specifically about living life by design. Authors Bill Burnett and Joel Evans believe that anyone can design the life they love and live it to the fullest.
The book further pushes forth the view that there isn't one life to live but many, and that the ideals of success and happiness that most people have are not exactly true. The book opens with real-life examples of people who carried the wrong ideals of a well lived and successful life well into the latter part of their life and careers, only stopping to realise something was wrong when a part of them suddenly felt incomplete.
The concept of design is not easily understood by everyday folks. Most people think of it from an engineering point of view and imagine it involves the creation of new products, technology, and services. What they never imagine is that design can be used to create new lives. This is the crooked belief that the book sets out to straighten through its explanation of design and the way it can be used to remodel and reframe life and people's views of it.
The correlation between designers and their love for problems is examined in another section, with the book attributing the creation of most, if not everything, people use today to designers' ideas of using problems to get day-to-day solutions. Designers are always looking for questions so that they can find answers to their design ideas.
Readers learn the concept of reframing and how every common question gets reframed in life design so as to find new and more helpful answers for it. The reframing process is further explained as taking new information about a problem, choosing a new point of view and prototyping it afresh to find new solutions.
It is through this process that most design ideas are born. Following their step-by-step approach, the authors continue to introduce the main topic of the book, the Life Design process. They show how it can be used to better the life one's already living or create another one based on mere possibilities. They also explain its reliance on asking questions, researching, and team work.
The book also introduces a different type of thinking: thinking like a designer. Before deciding to use the Life Design process, the book provides readers with the five mindsets they are supposed to have and shows how they are best applied.

Building prototypes and models is an essential component of any design activity. Modern product development is a multi-disciplinary effort that relies on prototyping in order to explore new ideas and test them sufficiently before they become actual products.
Prototyping and Modelmaking for Product Designers illustrates how prototypes are used to help designers understand problems better, explore more imaginative solutions, investigate human interaction more fully and test functionality so as to de-risk the design process. Following an introduction on the purpose of prototyping, specific materials, tools and techniques are examined in detail, with step-by-step tutorials and industry examples of real and successful products illustrating how prototypes are used to help solve design problems.
Workflow is also discussed, using a mixture of hands-on and digital tools. A comprehensive modern prototyping approach is crucial to making informed design decisions, and forms a strategic part of a successful designer's toolkit. Respirators Rubber gloves come in different materials and should be inspected for tears before use. The best protection from airborne particulates and chemical hazards is from spray booths and fume hoods. Health and safety literature advises that respirators are the last line of defense.
Anyone considering the need for a respirator should have a health exam and seek professional training and advice in the selection of a respirator. At schools this typically starts with the health and safety committee and shop personnel.
Employers are required to adhere to stringent rules and laws when it comes to respirators. Disposable Gloves Disposable gloves are made of various types of material, including latex, nitrile, and neoprene.
These need to be worn when handling and using chemical materials. Some people are allergic to latex. Gloves should be inspected for tears before use and discarded after use.
Ear Protection Excessive noise for extended periods can cause damage to hearing, including hearing loss and tinnitus prolonged ringing in the ear. Earplugs are simple to wear and should be worn around noisy equipment. They are custom-molded to the ear channel. Earmuffs offer more sound protection.
Earplugs and earmuffs are worn around any noisy equipment. Long hair is an extreme hazard for the same reason and must therefore be tied back and covered where necessary. Proper clothing such as a lab coat can provide some skin protection against some chemical materials. Machine shop coats or aprons are worn to provide protection against dirt and oil, but should also be worn properly so that there is no chance of them getting caught in moving machinery.
Shoes should completely cover and shield the foot in order to provide protection against dropped objects or chemicals. Babin, Health Hazards Manual for Artists 6th edn. This includes understanding the safety aspects discussed above and taking the time to read material safety data sheets and instruction labels. It also means wearing appropriate clothing and proper protective equipment for the job at hand.
Never take any chances or rush; be patient. Never play around tools or dangerous environments; it is distracting both to yourself and others, and such behavior can cause accidents. Also start by doing an inspection of the work area for any hidden dangers. Areas around mechanical machinery should be kept clean of debris and dirt that could cause you to trip or slip. Also be aware of your surroundings, including people in your vicinity.
Any strange noises emanating from machinery indicates that you should turn them off and report the problem to a supervisor. Always consider safer methods or tools that would allow you to achieve the modeling objective. Seek professional advice if any doubt exists as to the safety of either equipment or procedure; the role of the model-shop technician is to provide instructions for using the tools and equipment in a safe manner.
Above all, exercise caution and common sense. Never work alone or unsupervised. Overfamiliarity can also be a source of accidents, especially when work is done without thinking through the steps and being cautious. Some materials are suitable for use in small, simple workspaces, whereas others require substantial modelmaking facilities. Many professional design studios will have simple modelmaking facilities available for their designers to make models for early exploration and testing.
Usually the simple models made by the designers themselves far outnumber the more complex models and require much less complex tools and facilities. Basic Setup Work Surface A good work surface is key to being able to do good work. The table should be clean and stable. It is a good idea to have a replaceable top surface if the bench is used a lot. This can be as simple as a thin sheet of melamine or hardboard, which can easily be replaced when worn out.
The work surface needs to be kept clean and smooth. Vises Vises are a simple and necessary part of working by hand with harder materials such as wood, high-density foam, and metals. Holding these materials in your hands while working on them will not provide enough resistance and is also unsafe. Bench vises are securely attached with bolts to the workbench. They can usually tilt and rotate and have heavy jaws for securing the workpiece.
You can also use soft jaws, which are inserts made in aluminum with rubber linings that prevent the workpiece from being marred.
It allows you to see better and therefore leads to better workmanship and level of detail. These are ideal for modelmaking and are readily available. The magnifying glass will come in handy when examining the model for detail. Dust and Dirt Control It is important to contain and collect dust that is generated from sanding. If any power tools are used some form of dust-collection system will be necessary. Work Habits Try to develop good work habits. This is mostly common sense, but once bad habits are begun then they become ingrained.
Good habits include: Dust may also be generated when working by hand. This is especially true when using modeling-foam materials, which cling to everything. It is important to keep the dust from accumulating by regularly vacuuming the area.
It applies to any skill, including sketching as well as modelmaking. It needs to be learned, but with time becomes a natural process. The experienced sketcher knows how to draw a perspective view of an idea with little effort.
Similarly, the experienced musician is able to play the instrument as an extension of his or her own body. Prototyping is a similar type of skill, where practice will make it more natural and effective to go and build to explore, test, communicate, and verify your designs.
You will develop a sense of method and materials through practice. There is no formulaic or correct way of doing something, except for safety matters. This book serves as a foundation upon which new knowledge and experience can be built.
There are many different modelmaking techniques and approaches, and you will learn new tips and tricks along the way. The instruction manual guides the customer through the process of putting it all together and some tools are required.
The aspiring designer needs to learn both how to make things and how to instruct other people to put them together. Modelmaking is a great way to become more familiar with materials, construction, and assembly. In early models this is typically a single material, while for more advanced prototypes several materials and processes tend to be combined.
The second task is to plan what pieces need to be made and how. For simpler, exploratory models this is a simpler and looser process. In essence the model, rather than the product, is being designed at this point. These prototypes should be drawn to scale in either 7 54 Modelmaking 2D or 3D. This effective technique saves a great deal of time and helps with workmanship. Conversely, the layout can be used to create templates for outlines and cross sections. Pieces can also be laid out in 3D, as needed for rapid prototyping or CNC machining.
Generally, layouts progress from 2D to 3D as the project advances. It is also common to mix handmade parts with rapid prototyping. Making Parts Subtractive modeling involves removing material from a solid block of material. Conversely, in additive modeling material is added bit by bit. This could be compared with carving a sculpture out of stone versus laying it up in clay. As a rule the additive approach is faster and more effective, since most forms are resultant combinations of basic geometric elements.
One of the tricks behind modelmaking is to learn how to create essential pieces that can be glued together into the required shape. The best way to learn how to do this is through hands-on practical experience and modelmaking exercises. The step-by-step examples in this book will serve as a guide to that process. Breaking the model into bits is also fundamentally different depending on whether you are making a looks-like or a works-like prototype. In the latter it is a matter of breaking down the prototype into the required functional parts.
In both cases this process starts with some sketching and quick planning and then progresses into more detailed sketches or full-scale templates. Otherwise, masking will create a lot of extra work and invariably lead to worse results. Not all models are painted. If the model is to be painted then you should choose the paints and colors carefully.
It is best to paint parts prior to assembly in order to achieve a neater appearance. If the model is simply made for show and tell then it may be wiser to not assemble parts permanently, just in case something needs to be tweaked or changed in the future. This can be used to show a product in an open and closed state or to show variations.
Assembly of parts will therefore also depend on purpose. In this case the exposed fastener may not look good, but that is probably of no consequence as it is only a works-like prototype. For looks-like prototypes it may be simpler and easier to glue parts together, even if that is not how they would be held together in production.
Typical products that are modeled sculpturally include cars, helmets, and character toys. Pictures and Measurements A basic way of reverse-designing a product is with a digital camera and some manual measurements. Some useful tips: — Take pictures from side, top, and front elevations and bring them into the computer system aligned on to these planes.
This will form a good starting point for the model. A picture taken farther away will have less distortion. Align the camera to have a dead-on view. It may be necessary to mark up the model in order to create reference points that can be traced back to the pictures. Consider using drafting tape as it is low-stick, marks well, and can be removed afterward.
This serves as an excellent guide. Laser Scanning The NextEngine stationary desktop scanner includes a rotating mounting base that automatically rotates the object to be scanned. Laser scanners are either handheld or stationary. The handheld scanners are suitable for scanning large surfaces, such as car bodies. A scanner can scan only what it sees. This means that either the operator needs to move around the object during the scanning process or else the object needs to move relative to the scanner.
The quality of the software provided with the scanner is important, as the process can be largely automated with good software. This data was then in turn used to mill a full-size car model in foam. Portable GPS with new battery door containing a clip-on bracket for a bicycle handlebar. The new battery door white was printed on a Dimension 3D printer, based on data scanned in from the original battery door black.
It is a wise investment to start building this toolkit while in school, as it will serve you as a practicing designer for years to come. Keep your tools in a suitable toolbox. A good toolbox is essential for safely organizing and storing your personal tools. Steel rule top , steel square with adjustable base middle , electronic vernier caliper bottom.
Layout and Measurement Good workmanship starts with accuracy of measurement. The use of appropriate measuring tools is crucial to obtaining reasonable results. The steel rule is used to mark straight lines or to guide cuts with a box-cutter or X-Acto blade.
The steel rule can be used to measure overall dimensions to an accuracy of half a millimeter at best, which is why a set of electronic vernier calipers are used for dimensional accuracy instead. The caliper measures thickness, depth, and width to an accuracy of one hundredth 0. Steel squares are used to mark a perpendicular line to an edge of material. They are also used to create a vertical line when standing on the adjustable base.
Rasps have large teeth and are essential for rough shaping of wood and other soft materials. Pliers come in many shapes and sizes, including diagonal, long nose and combination types. Different grit sandpapers are required for modelmaking. Cutting Tools Precision-cutting tools include the X-Acto knife and the box-cutter. These should be stocked with an ample supply of sharp replacement blades. Make sure not to leave knife blades exposed and to keep all knives and blades safely away from children.
Also wear eye protection, since a snapped blade creates a potential hazard. A cutting mat is essential for safety and will extend the life of the cutting blades, protect furniture, and create a better and cleaner cut. Specialty cutters such as the circle cutter or a miter cutter are not essential, but can save time.
Rasps will work effectively at removing large amounts of material from wood or foam. Files also work on a variety of materials and are useful for removing burrs and sharp edges on metal and plastic sheet.
These tools are always used in conjunction with a vise to secure the workpiece. Assortment of Other Small Modelmaking Tools Other small handheld tools include a hobby saw as well as pliers to hold small pieces while gluing and also to bend or cut small pieces of metal or wire.
Sandpaper Sandpaper varies in coarseness, or grit. The lower the grit number, the coarser the paper. Sandpaper with grit below is very coarse and will remove material quickly and can therefore be used to shape a surface. Different grits are therefore used in succession. Handheld power tools are quite common and are sold for professional as well as home use.
Stationary power tools include hobbyist varieties. The last category consists of larger industrial machine tools. Never operate any power or machine tool without obtaining professional training and supervision. The following description of various power tools is simply an overview of what they are used for and should in no way be interpreted as a substitute for proper training and education in the use of these tools.
As a general safety preparation: Handheld drill, circular saw, and jigsaw. A rotary hobby tool is a versatile modelmaking tool. It is supplied with a number of tool bits for cutting and grinding, as well as sanding. They are a useful addition to most basic toolkits, given their small size and versatility.
Dremel is a popular brand of these tools. Larger handheld power tools include a cordless drill, a circular saw for cutting sheet materials, and a jigsaw for cutting more complex outlines in sheet materials. Stationary Power Tools Drill press speed can be adjusted through a pulley arrangement between the motor and spindle. This should only be done when the machine is stopped and unplugged. The chart on the bottom of the guard cover on this machine shows speed options.
Drill Press The drill press is more accurate than a handheld power drill and will provide more guidance and control during the drilling operation. Drill presses can also be used with circular saws, drum sanders, and countersinks.
The drill bits are mounted in a chuck that turns via a motor. The speed can be changed through a pulley arrangement on top of the machine, which should only be adjusted when the machine has stopped and is unplugged. Different materials require different cutting speeds. Steel, for example, needs to be cut at a slower speed than aluminum and also requires that cutting oil be used.
A smaller diameter tool also requires a higher speed than a large diameter tool, since the velocity at the tool perimeter is lower. Refer to a drill speed chart for recommended speeds. A dislodged piece will then hit the back column — Do not wear gloves that can become caught in the rotating spindle — Never try to stop the drill by hand — Unplug the machine before changing speeds — Remove chuck key before starting the machine Bandsaw This is one of the most versatile power tools for modelmaking purposes.
It can be used to cut a variety of materials, including plastics, polystyrene foam, polyurethane modeling board, wood, and metals. A 14in 36cm bandsaw is a standard feature in many small workshops. The bandsaw blade is tensioned between two wheels that rotate it in a circular path. The bandsaw can be used to make straight or angled cuts, as well as curved cuts.
This power saw can do the jobs of most other saws put together. A thin blade will allow the bandsaw to work like a jigsaw and cut the most intricate detail, whereas a thick blade will allow for a straight-line cut much like a table saw. Different types of drill bits from left to right; countersink, twistdrill, spade drill, and holesaw. The bandsaw is a versatile shop tool for sawing straight as well as being useful for contoured cuts. Since the saw blade is removable it can be inserted into a hole opening to create the cut from inside.
If a scroll saw is not available, a handheld jigsaw can usually be used. Scroll saws have an upward and downward stroke that tends to pull the workpiece vertically. It is therefore important to maintain a good grip on the workpiece. Smaller desktop machines are usually combined into one unit.
The post sander is a useful tool for sanding cavities and concave shapes. It can also be used to shape circular openings after scroll sawing. In addition to the general safety preparations listed above: — — — — Disk sander top and small desktop belt sander above. A post sander creates concave curves in various diameters right, above.
When used in a safe, professionally supervised situation, then manual machine tools are still very useful as they produce very accurate parts. The cutting speeds and feeds have to be controlled and are a function of the material and cutting operation. Lathe Woodworking lathes and metalworking lathes are two different types of machine that operate on the same principle. The workpiece is rotated, also known as turned, against a cutting tool that removes material to create radial symmetry, for example, bowls or cylindrical and conical shapes.
The size of a part is limited to the maximum diameter that can be swung above the bed while turning. This is a function of the clearance between the bed and the revolving headstock spindle. The workpiece can be mounted directly onto a faceplate, held in a chuck or between the two mounting ends.
Proper setup and mounting is highly dependent on the shape of the part and the operation. It is therefore very important to get a technician to advise and guide you through the steps. In the woodworking lathe, the cutting tools are held and guided by hand. This means that the accuracy is dependent on skill. Material is removed gradually and in steps.
Templates are usually used to check the form, but only while the machine is turned off and the spindle has stopped turning. There are a wide variety of cutting tools that are suitable for different types of cut and detail. The basic tools include gouges for material removal, chisels for detailing, and parting tools to cut deep grooves or to separate the part.
The metal-cutting lathe is a much more complicated piece of machinery. The cutting tools are guided and held in a carriage that can be accurately positioned using a hand wheel or a power leadscrew. This is a precision tool where all measurements are calculated and measured using the dials and settings on the machine. Metal-cutting lathes are also used to machine screw-threads. Please see the safety reminder at the end of this section as well. A wood instructor supervises a student using a wood-turning lathe.
This bowl-shaped vacuum-forming mold was made on the wood-turning mill using a computergenerated template as a guide. The metalworking lathe is a high-precision machine that moves the cutter along three axes to cut circular items. In this case the brass workpiece is held in a 3-jaw chuck. A clear polycarbonate guard is folded down during the machining. Smaller desktop mills simply have a movable XY table, whereas larger knee mills allow the table to be raised and lowered as well, to accommodate larger workpieces.
The accuracy of the movement is based on manual or electronic indicators. The head on the mill can be swivelled to perform angled cuts. A rotary axis can be added to machine circular shapes with a mill similar to turning. End mills come in different diameters and lengths, suitable for a variety of cutting operations. The end mill can be used to mill holes, slots, pockets, and surface cuts. For example, a pocket can be milled by lowering the end mill into the material and then tracing the contour of the pocket.
A knee mill can be used to create a variety of accurate cuts. It is paramount to understand that whereas this equipment is useful and a valuable teaching tool, these are dangerous and powerful tools that can easily cause very serious harm or death if treated casually or without proper training and supervision.
In addition to the general safety measures listed in this book: — — — — — — Do not operate any machine without adequate training and supervision Never attempt a setup or operation that you have not been trained to do Know exactly where the emergency stop and off switches are located Make sure all safety guards are properly in place Always wear safety glasses Tie back long hair.
Remove loose clothing and jewelry that could become caught in the machine. Also known as solid freeform fabrication, additive manufacturing, or 3D printing, this technology has revolutionized modelmaking by enabling physical prototypes to be output directly from the computer. This ability has greatly affected the speed of product development. The complexity and detail inherent in rapid-prototyped parts is especially useful when creating models of injection-molded plastic parts.
It is necessary to have access to a 3D CAD program, and the required skill therefore moves from being able to build the parts physically to being able to manipulate 3D geometry on the computer. The type of software used also affects the process. Once the 3D CAD geometry has been created as a solid, it is possible to create a rapid prototyping part.
Such parts as these can be printed in a matter of hours, allowing students to incorporate more detail into their projects. It is important to set the tessellation quality to be appropriate to the surface being generated. Rapid prototyping software then creates a series of sections, or slices, taken vertically through the model. These sections will be used to produce the 3D model. Each slice must be described as an enclosed area, which is printed sequentially one layer on top of the next until the entire volume has been created.
The software also has to determine if there are areas where a section is unsupported during the printing cycle.
This happens when the geometry is overhanging or otherwise unsupported from below. The rapid prototyping systems therefore need some way in which to add support structure during the printing process in order to prevent the model collapsing while being built.
Part orientation during the build is a major consideration since it affects how much support structure is required. There are many differences between the various rapid prototyping technologies.
It does, however, highlight some of the inherent advantages and limitations of various systems. It is worth considering many different issues when selecting a process for prototyping as in most cases it is a matter of trade-off between cost, speed, and material properties. CatalystEX software is used to prepare a part for printing on a Dimension 3D printer. The software creates support structure automatically. At that time 3D solid modeling software was also expensive and less common than 2D drafting programs.
The next ten years saw a drastic reduction in cost of solid modeling software and as it started to become the norm, the demand for rapid prototyping parts grew substantially. New RP technologies started to emerge to tap into this larger market.
Whereas the industrial systems have tended to have larger build volumes, more material selection, and better resolution than their 3D printing counterparts, there is rapid convergence in terms of these qualities that keeps making 3D printing ever more accessible and desktop-friendly.
There are some limits though—at the time of writing the 3D printer systems offer very limited elastomeric or clear plastic part capability, although this is possible with higher-end systems. Some industrial systems are now starting to compete with mass-production technologies such as injection molding. Tool-free production means you have the freedom to make changes more easily, get up and running faster, and not have to worry about sink marks, draft angles, and a host of other injection-molding issues associated with steel tooling.
The onus on the industrial systems is therefore to reduce postoperative procedures, while increasing accuracy and throughput in order to be competitive. The material selection is an important aspect of prototyping.
The range of material properties needs to be considered carefully in the prototyping process, as there are associated trade-offs in cost, strength, surface quality, and color. If it is a works-like prototype that is to be handled and subjected to loads, it will need to have more strength than if it is a looks-like prototype made mostly for show and tell.
For interactive electronic products, rapid prototypes are perfect because electronic components can easily be incorporated. For casings that are meant to be repeatedly assembled and disassembled, it is advisable to use threaded brass parts that are typically inserted into plastic bosses using a soldering iron.
They can also be glued into oversized holes with cyanoacrylate glue see page These allow easier opening and closing of the housing using machine screws. Layer Thickness: The Staircase Effect The surface quality of the parts is dictated by how thick the individual print layers are. The surface will be approximated by a series of parallel cross sections, so the thinner these are the closer they will replicate the surface smoothness. The effect is more visible on curved surfaces and is called a staircase effect.
Orientation of the part during the build cycle is also important as it can greatly affect the surface quality of the part. A cylinder built vertically will have smooth sides, whereas if built on its side it will need support and have substantial staircasing. Post-Processing Post-processing includes everything that needs to be done to the part after it is removed from the prototyping machine.
This can include removal of support structures, material curing, or infusion of strengthening materials. The 3D printing systems are generally capable of smaller parts than their industrial equivalents. The staircase effect is more visible on a gradually curved surface and with systems that use thicker build layers. Given the fairly high cost of the materials, this is often where it becomes important to consider less expensive modelmaking routes that involve an approach other than rapid prototyping.
Material Cost There is generally a trade-off between cost, surface quality, and material strength. The cost of the material also needs to be considered in terms of cost of support structure material typically a secondary material and any secondary processing, such as secondary material infusion for strength. This again is highly dependent on the purpose of the prototype. This is where it makes sense to have the best possible surface quality to begin with. The basic level tends simply to include removing the support structures and perhaps bead-blasting the parts.
A still higher level might include further sanding and primer ready for paint. The inside of the part on the right shows what it would look like if painted without extra preparation. The extra powder surrounding the parts presents some inherent advantages. First of all it serves as a natural support structure. Secondly, the extra powder is simply reused, thereby minimizing material usage.
The powder also allows parts to be nested easily, without the need for more complex support structures to bridge the parts. Powder-based materials are used in industrial as well as desktop 3D printer systems, but the process and materials used in the two systems shown in this book differ markedly from each other. The technology has been around since the early s and is therefore one of the pioneering methods of rapid prototyping.
These industrial RP systems will produce parts in a wide range of materials that are selectively sintered with a laser. It works by depositing a thin layer of powder material in a build chamber, which is then selectively sintered fused with heat from a CO2 laser.
The process is continued layer by layer until the part is complete. The materials include a variety of consumer- and engineering-grade plastics: polypropylene for living hinges, glass-reinforced plastics for strength, and elastomeric materials to produce anything from shoe soles to gaskets.
SLS also produces durable plastic and metal parts through direct laser sintering that are also suitable for end use applications. The sPro Selective Laser Sintering machine is used to create parts in a range of consumer and engineering grade materials. The basis of its technology is the use of consumer inkjet printing on top of a layer of plaster powder. As the inkjet prints the cross section it applies a binder that holds the printed area together.
Thanks to a multiple printhead approach, each layer prints very quickly, allowing a high vertical build speed. As the printers increase in size and cost, they also tend to offer a higher throughput, better accuracy, and more colors. The accuracy and strength of this SLS prototype for the Motion Computing J tablet allowed mechanical testing at the critical stage of design and engineering implementation.
The simple and low-cost material is excellent for conceptual modelmaking, but the strength of the parts as printed is somewhat limited in functional applications. The strength can, however, be increased through post-processing. Water Clear is a saltwater-based infusion system that models are dipped into. The printed part is removed from plaster build tray. Parts are infused with salt water, cyanoacrylate, or two-part epoxy depending on the intended use and application. FDM is available both as high-end industrial machines and smaller 3D printer systems.
Parts can be made in ABS, polycarbonate, or Ultem engineering-grade plastic. The Fortus mc from Stratasys is an industrial 3D production system capable of producing parts in a variety of engineering-grade plastics. There is a separate cartridge for the material used for the support structure. Depending on the machine model, the support structure is either an easy breakaway material or a water-soluble material. The water-soluble type of structure is more suitable for thin-walled and delicate parts that may be damaged in the breakaway process.
Support structures are either washed away in a special water-based solution or simply peeled away in the case of the breakaway system. Small-scale production of parts in real plastics saves money on injection-mold tooling. Dimension 3D printers use real ABS plastic to create parts. ABS material spool cartridge loaded into the 3D printer.
A similar cartridge exists for the support structure material. The part is removed from the platen with a steel scraper and the breakaway support structure is then manually peeled off. Liquid-Based Systems Liquid-based systems use photopolymers that are cured with an ultraviolet light source.
SLA is characterized by high surface quality and smoothness of the parts. The technology makes use of a UV laser that is directed on to the surface of a vat of photopolymer. The hardened section can be lowered and recoated with photopolymer so that the next section can be created.
This process continues until the entire part has been created. Support structures are generated during the build to support overhangs and voids within the object. After printing, the support structure is removed. There is a wide range of materials available for this process that mimic the material properties of some common plastic production materials. Stereolithography machines from 3D Systems, such as this SLA, produce parts from laser-cured photopolymers.
Large, accurate SLAs are commonly used to verify part design prior to tooling production. These systems also produce very smooth high-quality parts. The support system is cleaned off in a wash station left.
There are also rubberlike materials that simulate the properties of thermoplastic elastomers or silicone. The parts require no post-curing, but the support material has to be washed off. Objet parts are characterized by extremely thin build layers producing high-quality surface parts. They are currently limited to printing rigid opaque type materials. This also allows the machine to simulate plastic injection molding of parts with overmolded elastomeric sections.
