Additive Manufacturing 101: How to (re)design your parts for Additive Manufacturing

(Image: 3D Hubs)

Redesigned concept of a carburetor (Image: Cassidy Silbernagel)

  Mechanical Design Engineer and Additive Manufacturing Ph.D. student

This is the final article in a series of original articles that will help you understand the origins of the technology that is commonly called 3D printing. First an introduction, followed by the seven main technologies categories (binder jetting, directed energy deposition, material extrusion, material jetting, powder bed fusion, sheet lamination, vat photopolymerization) and now a design philosophy for additive manufacturing.

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.
https://www.linkedin.com/pulse/design-metal-am-beginners-guide-marc-saunders/

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.

Orientation

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.

Post-Processing


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.

Advantages

  • Easiest
  • Less material wastage
  • Direct single part replacement
  • Potential faster lead times
  • Allows easier manufacture of complex design

Disadvantages

  • 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.

Advantages

  • Improve performance
  • Decrease weight
  • Improve printability
  • Direct single part replacement
  • Less material wastage

Disadvantages

  • 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.

Advantages

  • Allows reduction of parts
  • Reduce assembly
  • Potentially less risk than a complete redesign of overall machine/assembly

Disadvantages

  • 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.

Advantages

  • Allows greatest performance increases
  • Eliminate parts and assembly
  • Reduce weight, cost, lead time

Disadvantages

  • Most amount of design effort

Wohlers Associates deliver first ever DfAM session in Canada

Wohlers Associates, represented by Terry Wohlers and Olaf Diegel, delivered its first and successful session in Montreal, Quebec. The June 12-14 Design for Additive Manufacturing (DfAM) course, sponsored by Canada Makes Partner CRIQ, was attended by bright and relatively young people experienced with CAD.

Participants came from a variety of sectors, including aerospace, industrial equipment and machinery, CAD and AM product sales and services, academia, government, and research. All with a common goal of of taking the next step in designing for AM. 

Terry Wohlers offered this about the session, “some of the participants said that they especially appreciated the hands-on topology optimization and lattice structure exercises. One participant stated that he attends many technical AM events and this one was, by far, one of the most valuable. Another said he appreciated that lead instructor Olaf Diegel spoke French, although most of the course was conducted in English.”

“Learning how to Design for Additive Manufacturing (DfAM) is critical for maximizing the output from your Additive Equipment,” said participant Hargurdeep Singh Director of Additive Manufacturing CAD MicroSolutions Inc. “Terry Wohlers and Olaf Diegel presented an excellent demonstration of DfAM. I particularly enjoyed learning about the Generative Design and Part Consolidation exercises using hands-on learning techniques.”

The average score given by the participants was 4.9 on a scale of 1 to 5, with 5 being best, so we were quite pleased with it.

Wohlers Associates will be holding another special three-day course on design for additive manufacturing (DfAM) in Frisco, Colorado August 8 to 10, 2018wohlersassociates.com/DfAM.html

Ottawa Symphony Orchestra and Canada Makes Announce the Winner of the National 3D Printed Musical Instrument Challenge

Ottawa, 14 June, 2018 – Ottawa Symphony Orchestra and Canada Makes are pleased to announce Robert Hunter as the winner of the National 3D Printed Musical Instrument Challenge for his design for clarinet and brace which improve the ergonomics of the instrument by redistributing the weight of the instrument to larger muscle groups compared to traditional instruments. The award will be presented to Robert Hunter in person at Ottawa Symphony’s Open House event on Thursday, June 14th between 5-7pm at Dominion Chalmers (355 Cooper St.) in Ottawa.

“I was interested in this competition because of my combined background in biomedical engineering including biomechanics, 3D CAD design, and music. I used to play clarinet a lot in high school, and when I would practice for long periods my right thumb would become sore from supporting the weight of the instrument. So when I read about this competition, this problem immediately sprang to mind for something I could try and solve.” – Robert Hunter


The National 3D Printed Musical Instrument Challenge asked participants to improve or design an ergonomically optimized musical instrument that leverages the power of 3D printing (metal or polymer) for its fabrication, while remaining cost-effective. The designers were encouraged to consider how they could contribute to solving the epidemic of performance related injuries among professional musicians and music students by addressing root causes of the issue insofar as it relates to instrument design.

“Hunter’s design directly addresses an ergonomic injury risk to the musician and his proposal included an assessment of both playing aesthetic and technical demands. Bravo!” – Dr. John Chong.

“While music lifts the soul, many musicians – professionals and amateurs alike – struggle to perform due to injury. This challenge was an invitation to designers to employ new technology to the benefit of musician’s health. We were so pleased with all the creative ideas we received, and specifically, to award the KUN Prize to Robert Hunter.”– Alain Trudel

Applicants represented regions across Canada, a variety of levels of design experience and wide-ranging innovative solutions to common health problems among musicians. The submissions were evaluated by a panel of eight adjudicators with equal weighting between disciplines of 3D printing, music performance, and musicians’ health.

As the winner, Robert Hunter will receive the KUN Prize, valued at over $35k, which includes a fabrication and fitting budget, a 5min piece of music commissioned for the instrument, performance of the instrument at the Ottawa Symphony Orchestra’s 3D StringTheory concert on November 4th, and a $5k cash prize. The KUN Prize is sponsored by Marina Kun, President of KUN Shoulder Rests Inc., and fabrication is sponsored by Precision ADM and Axis Prototype Inc.

About the 3D StringTheory Project:

3D StringTheory asks:
What new instruments and sounds can we create using today’s newest technologies?

To explore the new creative possibilities that technology brings to music, the Ottawa Symphony Orchestra has commissioned Ottawa violin maker Charline Dequincey and the Industrial Technology Centre in Winnipeg to create original 3D-printed string instruments. Montreal-born composer Harry Stafylakis will write an original piece of music inspired by these new sounds. The Ottawa Symphony Orchestra will present the final product of these collective efforts in a live performance of Stafylakis’ piece, featuring the new instruments on November 4th, 2018.

The project will also feature public competitions involving instrument making and design challenges for youth, university students, and professionals. The 3D Printed Musical Instrument Challenge is the first competition to be announced.

The full process of creating the 3D-printed string instruments will be documented through a video series available for the public to follow and engage with online and through social media.

3D StringTheory explores how today’s new technologies, like 3D printing, can further expand musical boundaries.

Canada Makes 3D Challenge Trophy, Concept to Product

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.

Winning team of Yanli Zhu and Lisa Brock of the University of Waterloo with Frank Defalco of Canada Makes

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

 

Additive Manufacturing 101-7: What is vat photopolymerization?

Vat Photopolymerization (Image: 3D Hubs)

  Mechanical Design Engineer and Additive Manufacturing Ph.D. student

This is the eighth article in a series of original articles that will help you understand the origins of the technology that is commonly called 3D printing. First an introduction, followed by the seven main technologies categories (binder jetting, directed energy deposition, material extrusion, material jetting, powder bed fusion, sheet lamination, vat photopolymerization) and then a design philosophy for additive manufacturing.

Vat Photopolymerization

ISO/ASTM definition: “vat photopolymerization, —an additive manufacturing process in which liquid photopolymer in a vat is selectively cured by light-activated polymerization.”[1]

Vat photopolymerization can also be known as (in alphabetical order):

➢ Continuous Liquid Interface Production or CLIP[2]

➢ Scan, Spin and Selectively Photocure Technology or 3SP[3]

➢ Solid Ground Curing or SGC[4]

➢ Stereolithography or SL[5]

➢ Stereolithography Apparatus or SLA® (3D Systems Corporation)

➢ Two-Photon Polymerization or 2PP[6]

Stereolithography was the first AM process to be invented. The first patent was filed in 1975 which described a two-laser 2PP process[7]. The first parts were made by Dr. Hideo Kodama of Japan using SL in 1981[8]. Additional patents followed in 1984 when in three different parts of the world, people patented the SL processes. First on May 23 in Japan by Yoji Marutani[9], then on July 16 in France by Jean Claude André, Alain Le Méhauté and Olivier de Witte[10], and lastly on August 8 in the United States by Charles W. Hull[5]. Chuck Hull was the first to commercialize the technology when he founded 3D Systems in 1986. In 1988, 3D Systems commissioned Alberts Consulting Group to create a file format that could be sliced, resulting in the STL file format[11]. In 1991, Cubital introduced the Solid Ground Curing process but later ceased operations in 1999. In 2015 Carbon3D introduced a novel concept named CLIP using an oxygen-permeable bottom plate to help speed up the printing process. As the original patents surrounding this technology have lapsed, many startups have emerged taking advantage of this original AM process.

vat photopolymerization

vat photopolymerization example

Figure 1: Vat Polymerization example setup[12]

This process involves using a liquid resin as the main type of material. Specifically, this liquid resin has the special property of being able to become solid once it is exposed to light. This light can be ultraviolet as in SL processes, or for 2PP, with two photons of near-infrared (NIR) light hit within a very short period of time (several femtoseconds)[12]. This liquid resin is held in a container or vat, in which a flat build platform is partially submerged. This platform starts near the surface of the liquid and then gets exposed to light. This light can be a UV laser(SL), a digital light processing (DLP) projector, a UV light bulb filtered through a printed mask(SGC), an LCD screen similar to home theater projectors(CLIP), or even from very quick pulses (femtoseconds in length) of near infrared (NIR) laser light tightly focused to a very small area(2PP). Once the resin is cured and made solid, the build platform either moves further into the vat, or partially comes out of the vat leaving the solid cured portion just under the surface and then the process is repeated. In the case of SGC, the uncured resin is removed and then replaced with a liquid wax that solidifies, and then both the cured resin and wax is machined flat using a cutter and prepared for the next layer. If the process involves the platform coming out of the vat the resin needs to be transparent or have the solidification process occur at the very bottom of a vat with a clear window or bottom. However, this can cause the resin to solidify to the bottom which would prevent the platform from moving, or cause it to solidify so closely to the bottom that when the build platform moves up, significant suction is created which results in very slow movements. Recent developments by Carbon3D and the creation of the CLIP process have resulted in very quick builds due to the clear bottom acting as an oxygen permeable membrane which inhibits solidification of the resin within a certain zone around the clear bottom of the vat, which eliminates this suction force. This has shown to increase build speeds from 25-100 times compared to other AM processes, including SL.

Advantages to this type of AM are that it is capable of very high detail surface finish, even down to the nano-scale level, it can be very fast compared to other processes in terms of pure volume, and it’s also able to be scaled up to build desk-sized objects in very large vats.

Disadvantages include a limited number of material properties found in UV curable resins, which are not the most robust materials in terms of durability, strength, or stability. These resins can change shape over time, potentially change colour, and usually need a post-curing UV light oven to cure the material fully in order to get the most strength out of them. Some resins are also toxic and special gloves need to be used to handle parts until they are fully cured. Depending on the geometry of the part, support structures are required and can be very complex and require manual removal afterwards.

Nanogrande moves into a new larger facility

NanograndeMontreal, June 6, 2018— Canada Makes partner Nanogrande has moved to a new location in Montreal, multiplying the company’s floor space by four times of its previous business space. Mr. Juan Schneider, president and founder of Nanogrande, warmly welcomed his team to the new workspace this morning. Thanks to PME MTL Centre-Ouest, the company is entering a new phase of development that will see its tremendous increment in production and research capacity.

This new premise will truly open up the company’s potential for growth and creation,” said Schneider. “We now have the space to fully deploy our research and development department and our new assembly line.

This new workspace located in Montreal, a city with full technological explosion, will allow the company to get closer to the partners in its sector of activity to propel its development process. At the same time, Montreal being the capital of artificial intelligence, holds the key for Fourth Industrial Revolution, the heart of Nanogrande’s activity.

We have tried to stay close to our old facility, but the support we received from PME MTL Centre-Ouest convinced us,” said the president of Nanogrande. “The proximity of high-tech research centres, the many young companies in the sector and the determination of local decision-makers persuaded us to move our offices.
