Design for Additive Manufacturing
All of these following principles differ greatly for each technology category. Some are not a concern, others are a major concern. Before you design for AM, you need to know which process you are designing for, and if possible, what machine it will be built upon. Each machine and even different materials differ on some of these aspects.
Supports / Overhangs
Each technology deals with this differently. Generally, there is a critical angle (typically 45 degrees) that allows no support to be needed such as in the letter Y. Some need supports for all bridges of a certain length such as the middle of a capital H. Others need supports for overhangs such as at the ends of a capital T. How supports are designed or generated and removed needs to be thought of in the design process. By changing or re-orientating the design, you can minimise the need for supports, and change how the supports are removed.
Two factors come into play for orientation. First is material properties can differ depending on the direction they are built. This shows some test bars I printed to test how build orientation affects the electrical resistivity of a metal alloy. Strength can differ depending on build orientation so if you have a part that needs to have a certain strength in a certain direction, you will need to know how the orientation affects the strength of the part.
The second is that printed features can come out looking differently depending on orientation. If you have a circle you want to print and have it come out circular, you will need to orient the part so that the circle is in the XY plane and not chopped up by the layers.
Minimum feature size / Resolution
This greatly depends on the process you use, and especially the machine you use. Just because two machines from different manufacturers use the same technology, they may not have the same feature specifications. There are also many factors that play into minimum features, and each is different. Here you can see some of the minimum sizes for a typical SLS process in Nylon. This is where you need to find out the machine and material specific specifications if you want to be designing features in the submillimeter range.
There are many different ways post-processing can affect how you design. If the process relies on supports, they will need to be removed manually, or potentially semi-automatically. If attached to a build plate, the parts will need to be removed. If there is excess powder or liquid trapped, it will need to be removed. If you want uniform or enhanced material properties, a heat treatment or post infusing of a second material may be needed. If you have critical surfaces that assemble, post machining will be required including custom part holding jigs or fixtures. All of these need to be taken into consideration when designing in order to gain the greatest benefits from AM.
Four ways to (re)design parts
Method 1: Send directly for AM
Method 2: Modify for AM
Method 3: Combine and redesign for AM
Method 4: Rethink and redesign for AM
Method 1: Send directly for AM
The first and easiest is to simply take an existing design and without modification create it using AM technology. This is advantageous when the single part is excessively complex making it difficult to produce using traditional methods or made from materials that are expensive where minimal waste is desirable. This can also be desirable when the lead times for a part are excessively long or if the part is no longer manufactured.
- Less material wastage
- Direct single part replacement
- Potential faster lead times
- Allows easier manufacture of complex design
- Narrow scope of use
- Limited potential gains
Method 2: Modify for AM
The second is to redesign the single part to either improve performance and/or to make the part better suited for AM.
- Improve performance
- Decrease weight
- Improve printability
- Direct single part replacement
- Less material wastage
- Requires same assembly methods and parts
Method 3: Combine and redesign for AM
The third is to combine multiple parts to aid in part reduction, reduce assembly costs, and enhance performance.
Before 3D printing, this fuel nozzle had 20 different pieces. Now, just one part, the nozzle is 25% lighter and five times more durable.
- Allows reduction of parts
- Reduce assembly
- Potentially less risk than a complete redesign of overall machine/assembly
- Requires more design time
- Requires testing and validation
Method 4: Modify for AM
The fourth is to completely rethink the assembly and redesign according to basic first principles and design requirements. While this complete redesign can yield the greatest results, it takes the most time and effort to achieve.
Image: Optisys LLCThe test project involved a complete redesign of a high-bandwidth, directional tracking antenna array for aircraft (known as a Ka-band 4×4 monopulse array).
Reduce part count reduction from 100 discrete pieces to a one-piece device.
- Cut weight by over 95%.
- Reduce lead time 11 to two months. (eight months of development, three to six more of build time)
- Reduce production costs by 20%.
- Eliminate 75% of non-recurring costs.
- Allows greatest performance increases
- Eliminate parts and assembly
- Reduce weight, cost, lead time
- Most amount of design effort
View the following video showing the process of using both additive and subtractive manufacturing to go from a concept to a product. Thank you to our friends at Renishaw for sharing this wonder video.
The trophy was recently awarded to the team of Lisa Brock and Yanli Zhu from the University of Waterloo and their design of biodegradable packaging made from mushroom roots. canadamakes.ca/canada-makes-ann…eam-3d-challenge/
The award was presented during the first Conference of NSERC Network for Holistic Innovation in Additive Manufacturing (HI-AM) at the University of Waterloo.
Students were asked to focus on creating innovative tools or products that reduce our environmental footprint using additive manufacturing in tandem with conventional manufacturing approaches.
Lisa Brock and Yanli Zhu proposed the design of biodegradable packaging made from mushroom roots and agricultural waste using binder jetting additive manufacturing. The packaging design was created by optically 3D scanning the object. Approximately 10% of materials used in additive manufacturing can be recycled into new plastics, and the rest are disposed. The options for disposal are landfills and incineration, both of which increase the amount of greenhouse gases. Therefore, new biobased biodegradable materials must be developed to decrease the negative environmental impacts of these additive manufacturing plastics. https://youtu.be/XKU-BHKuGZI
The Additive Manufacturers User Group, AMUG to all concerned, held its 30th anniversary event last week at the historical Union Station Hotel in St. Louis Missouri and it did not disappoint. Attending AMUG is a unique experience plain and simple. The expertise on the floor at AMUG is unrivalled and the learning opportunities endless.
Picking a high point is hard but the roaring and dizzying speed of the NASCAR racetrack as our surprise destination on Award Night is hard to beat. The evening was highlighted with the announcement of Custom Prototypes’ Mark Antony Roman Helmut as the winner of the Technical Competition Advanced Finishing.
My friend and Canada Makes partner Hargurdeep (Deep) Singh, Director of Additive Manufacturing at CAD MicroSolutions Inc. said the following, “Additive Manufacturing Users Group (AMUG) Conference 2018 was a fantastic event to connect with many end-users, engineers, business executives and pioneers of the Additive Industry. This event provided an excellent resource for learning about the future of 3D Printing and I would like to acknowledge Frank Defalco for representing Canada Makes at AMUG 2018. Canada Makes representation helped bring together many partners who are now moving forward in helping Canadian companies to enable innovation and leverage AM technologies.”
Deep was kind enough to share some of his finer photos taken during the event. See if you can spot Deep hidden is some of the pictures.
About Additive Manufacturing Users Group (AMUG)
The Additive Manufacturing Users Group’s origins date back to the early 1990s when the founding industry users group was called 3D Systems North American Stereolithography Users Group, a users group solely focused on the advancement of stereolithography (SL) use with the owners and operators of 3D Systems’ equipment. Today, AMUG educates and supports users of all additive manufacturing technologies. The primary charter of the group remains the same, but its members are much more diversified, global and focused in advancing additive manufacturing technology for rapid manufacturing and prototyping.
With AMUG’s expanded range, operators/owners of any commercial technology — stereolithography, selective laser sintering, 3D printing, DMD, DMLS, FDM, LS, SL, SLM, PolyJet, and more * — can benefit from the information exchange and professional network that AMUG offers. www.amug.com
Additive manufacturing (AM) has been called the next Industrial revolution–. It is a recent technology that encompasses a wide range of different processes and materials. It is changing industries like aerospace by adjusting how engineers think about designing complex parts–. This revolution can take designs that have gone unchanged for decades and improve them.
AM was first conceived of in the 1970s with the first parts made in the 1980s and has had many names over the years.
- Layer manufacturing or LM
- Rapid manufacturing or RM
- Rapid tooling
- Rapid prototyping or RP
- Laser rapid prototyping
- Solid freeform fabrication or SFF
- Direct digital manufacturing or DDM
- 3D printing or 3DP
Initially, AM was used as a tool to create prototypes much more rapidly than could be done by other means and aided in the development of bringing new products to market, . It then helped create tooling, tooling inserts, jigs and fixtures that were used in the manufacturing of end-use parts, . It has continued to evolve and now is being used in making end-use parts such as low-volume production plastic casings, high-end consumer in-ear music monitors, GE LEAP jet engine fuel nozzles, and SpaceX SuperDraco rocket engine chambers and Falcon 9 main oxidizer valve bodies which have gone into space.
While AM has been around for three decades, it has yet to be utilized in the manufacturing of electric motors. Since the late 1800s, electric motors have seen only a small number of improvements, most of which have come from new and improved materials and new manufacturing techniques–. Yet the core design of motors has been relatively unchanged –. There is an evident opportunity to research how AM can change electric motor design. AM has the potential to produce new electric motors that can increase motor efficiencies and power densities.
Review of Additive Manufacturing
There are many different types of AM processes. Each has specific strengths and capabilities with unique areas of specialization. Regardless of the process, there are some fundamental principles that all follow.
Subtractive manufacturing usually starts out with a solid chunk of material that is larger than the final desired shape or part. Then using different tools, material is removed (or subtracted) until the final shape or part is achieved. It is important to note that casting is not considered additive or subtractive, but rather a formative process, as an existing mould or pattern is needed to create the final part.
Compared to subtractive, AM works in the opposite way. Instead of removing material to get the final desired shape or part, material is added to a build platform bit by bit. Most forms of AM follow these basic steps:
- Take a 3D model
- Slice model into layers and generate computer code
- Print first 2D slice and supports (if needed)
- Increment height
- Print next layer
- Repeat steps 4-5 until finished
- Post process (if needed)
A minor exception to these steps is when an AM process can deposit material in three-dimensional space. It is then not limited to just printing 2D layers one at a time–. AM can be a faster and more economical way to make parts, especially when the part is complex and/or made from an expensive material. These steps are still quite broad and have many details that can provide deeper insight.
AM process steps
Step 1: 3D model
The process begins with a computer-generated 3D model of the desired final part. The model needs to be capable of being printed, which means that it needs to occupy a defined volume. The part can’t be a single surface with a wall thickness of zero. Once it has thickness and volume, it then needs to be an enclosed watertight solid. This means that if water is put in the interior volume of the model, there are no holes from the inside volume to the outside surface. Even objects like a Möbius band or Klein bottle can be printed as long as the single surface is thickened to have a defined watertight volume.
Figure 1: Klein bottle and Mobius band show a surface with no thickness
Once the model is generated correctly, it needs to be saved to a specific file format. These specific file formats are needed in order for it to be prepared properly for printing. Thus it needs to be saved as either an STL file, AMF file or 3MF file. The STL file format has been the de facto standard since it was created in the late 1980s. However, it does have limitations which cause some problems. It does not store the units of measurement of the original model so they need to be assumed. Also, the file size becomes very large when trying to save a model with a high level of surface curvature. In response to these limitations, the American Society for Testing and Materials (ASTM) introduced the AMF file format in 2011. Then in 2013, Microsoft intended to do the same with its own 3MF format. This format became natively supported in all Windows operating systems since Windows 8.1. 3MF has since garnered considerable support from large companies such as HP, 3D Systems, Stratasys, GE, Siemens, Autodesk and Dassault Systems although it is unknown how many actively use this file format. Thus STL is still the file format of choice for almost all 3D printing. However, a newly signed liaison agreement between ASTM and the 3MF Consortium may bridge some differences between AMF and 3MF and create one new standard file format to replace STL.
Step 2: Prepare for printing
Secondly, special software is needed to turn that 3D model into data that a 3D printer can recognize and use. This usually involves cutting or slicing the model into many digital layers. Each layer is then converted into either a 2D image or into a set of 2D tool paths. The spacing between these slices will determine the printed thickness of the layers that will be seen in the final part. These layers partially determine the final surface quality and surface roughness of the final part, as well as how long the part will take to print. This height is an important compromise between print speed and surface quality, thus they are generally very thin. An average across several processes is around 100 µm or 0.1mm. Depending on the AM process, the range of layer heights is vast. In two-photon polymerization, layer features as small as 40nm or 0.00004mm can be created which is smaller than the wavelength of ultraviolet light. Microwave sintering can create layers up to 5cm or 50mm in depth. Regardless, when working in a process, the thicker the layer, the faster the build speed but the rougher the exterior becomes. Hence layer height is a trade-off between speed and quality.
Figure 2: T shaped structure with supports
Depending on the geometry of the model and the AM process involved, support structures may be needed. These support structures anchor overhanging areas of the final part to the build platform or other solid portions of the part. Imagine printing a 3D letter “T” starting from the bottom moving up to the top. The 3D printer would be able to print the main body of the letter without any issue. But as soon as it gets to the top, it would have a significant challenge to print the rest properly. The reason being there is nothing that would support the outreached arms of the letter. Thus some type of support structure is needed to be built up at the same time as the main body. When it reaches the point to print the arms, it would then be able to print on top of the main body and the support structure. An alternative option is to design the part for AM so that it does not need supports. For example, if the arms of the “T” were angled upward from the main body, the main body then becomes the support structure. The part would look more like the letter “Y”. Thus the letter Y could be considered a 3D print-optimized version of the letter T that doesn’t need support.
Steps 3-6: Printing
The specifics of printing depend on the process involved and will be described in much more detail further on in the report. Regardless, the 3D printer uses the computer code generated in the previous step to create an initial solid layer of material onto a build surface. The build surface could be a solid platform onto which the part is printed or a layer of unsolidified material that will support the part. This first layer is the first slice of the original 3D model that was calculated by the computer software in step two. Once the first layer is printed, the machine increments to the next height ready to print the next layer. This new height corresponds to the second slice of the original 3D model. The printer then creates a new solid layer based on that second slice. This new solid layer bonds to the previous layer making it one solid piece. The process repeats layer by layer until the final layer is finished. If the bonds between layers are weak, the build could fail or result in a structurally weak part. These anisotropic material properties can manifest as a weaker bond between layers than within layers– but can lead to beneficial properties for magnetic applications. There are some processes strategies,  and research projects that are addressing this concern with strength.
Step 7: Post-process
Finally, once a part is finished, it is removed from the build chamber and post-processed. This post process could take any number of forms. Some processes require removing support materials, . A few need to post cure the material to ensure a fully solid part. Laser melted parts need heat treating to relieve internal stresses that build up in the build process. Binder jetted parts can be placed in an oven to remove a sacrificial binder used in printing. Others are placed in ovens and sintered to increase the strength and density of the part. Infiltrants like glues or metals can be added to give more strength and higher density to the part, . Parts can undergo a chemical reaction to change the material for different material properties. Parts can be smoothed by chemicals, by blasting or tumbling to remove layer lines. Or parts can have some artistic flourish through hand painting, hydrographics, or even electroplating.
Methods and processes
Only recently was a standard designed for classifying the different ways something can be made using AM. In 2009, the American Society for Testing and Materials (ASTM) created a committee to define standards in AM technology. In 2010 they defined seven main technologies used in AM. This was given the standard designation: F2792–12a. As of December 2015, these ASTM standards were replaced with a new standard. ASTM joined with the International Organization for Standardization (ISO) to form ISO/ASTM 52900:2015. Despite having seven uniquely defined categories, there are many different processes within each category. Regardless, the overall method and the underlying principles discussed previously still apply. Variance exists only with the materials, deposition of layers, and methods of adhesion.
These seven categories will be explored in depth with their:
- alternate industrial or trade names
- a brief history
- description of method and materials
- advantages and disadvantages
These seven categories are (in alphabetical order):
- binder jetting
- directed energy deposition
- material extrusion
- material jetting
- powder bed fusion
- sheet lamination
- vat photopolymerization
The following are some common terms that are used when talking about these processes. They come from the ISO/ASTM definitions and are used throughout the seven category descriptions.
3D printer: the machine used for 3D printing.
Build chamber: the enclosed location within the 3D printer where the parts are fabricated.
Build platform: a base which provides a surface upon which the building of the part is started and supported throughout the build process.
Build space: the location where it is possible for parts to be fabricated, typically within the build chamber or on a build platform.
Build surface: the area where material is added, normally on the last deposited layer or for the first layer, the build surface is often the build platform.
Build volume: the total usable volume available in the machine for building parts.

A survey of the Canadian aerospace industry reveals a difference in perception among AM stakeholders
The following research project aims to facilitate the integration of metal additive manufacturing (AM) into the Canadian aerospace supply chain. Due to its versatility, AM could provide an interesting niche for Canadian manufacturing SMEs by allowing them to manufacture a large spectrum of metal products without an in-house foundry, forge or press. Canada is ranked among the global elite in the aerospace industry, and the development of AM expertise is essential to ensuring local suppliers remain competitive and keep pace with modern manufacturing.
HEC Montréal gathered the opinions of over 70 organizations from every level of the additive manufacturing (AM) value chain in order to measure the differences in stakeholders’ perceptions of AM-related opportunities, challenges, cost drivers and advancement initiatives.

The Maker phenomenon is spreading, directly North it seems. Not only is America making, but Canada is too, now, as Canadian Manufacturers & Exporters (CME) has launched Canada Makes. Like its southern counterpart — America Makes — this is a national network of excellence dedicated to the adoption and development of additive manufacturing in the home nation.

America Makes was the rebranded effort of the National Additive Manufacturing Innovation Institute (NAMII) in the US, which was certainly a mouthful when the acronym was not used, and nowhere near as inspiring to the nation’s increasing number of makers and young talent. Since the rebranding — and redoubling of efforts at every level of the making hierarchy in the US — America Makes really seems to have caught the imagination both in the homeland and further afield. I’m thinking it won’t be long before we see other national networks — set up and/or rebranded. ‘UK Makes’ doesn’t quite have the same ring to it, but given the surge in nationalism among these fair isles ‘England Makes’ could work, and Scotland can Make with devolved making power if it so chooses. Germany Makes maybe, Italy Makes, Australia Makes, China Makes — I could go on, but you get the idea.
However, right now Canada Makes, and according to Jayson Myers, CME’s President and CEO: “Additive manufacturing is one of those advanced manufacturing technologies that is likely to disrupt the way we are making things. CME is proud to take the leadership and promote its development among the Canadian manufacturing sector.”
Canada Makes has launched in collaboration with Sheridan College’s Centre for Advanced Manufacturing and Design Technologies (CAMDT), located in Brampton, ON. CME and CAMDT will organize three additive manufacturing workshops at CAMDT’s facilities in the next year in order to promote the adoption of additive manufacturing among SMEs. The first workshop is scheduled for October 16, 2014.
“CAMDT is one of the most advanced applied research labs in Canada and it has the latest technologies and software in the field of Fused Deposition Modeling (FDM). We are proud to help make this state-of-the-art laboratory available to small and medium-sized manufacturers across the country,” Myers said.
“Sheridan routinely partners engineering students with local businesses in need of 3D printing work,” said Director of CAMDT and Associate Dean of Mechanical and Electrical Engineering Dr. Farzad Rayegani.“SMEs gain access to equipment they otherwise couldn’t afford and benefit from product and process innovation. The students gain invaluable insight into the design challenges that manufacturing businesses face daily.”
Canada Makes will reportedly expand gradually into other areas of additive manufacturing, including metal 3D printing, and printable electronics. In addition to technology demonstration and training workshops, members of the network will also benefit from a customized service aimed at identifying potential partners and source of funding to complete their additive manufacturing projects, from prototyping to applied and fundamental research.
