design for additive manufacturing principles

So if you’re trying to improve a part or if you’re having issues printing a part don’t print the whole part if you don’t have to. Design for Additive Manufacturing (DfAM) is the process of adjusting your design to make it cheaper, faster, or more effective to manufacture. Some people think they have to come up with another manufacturing method, however, we can simply just segment the parts by cutting the part into whatever sections will fit in the printer and then bond them together. Operations are the people running the printers who will know what angle is self-supporting or not self-supporting and they will need to have communication with the engineering department. 2 BACKGROUND which delivers the highest strength and stiffness-to-weight ratio of any Stratasys FDM material. On the flip side, if you’re printing batches of printed parts the time spend optimizing will pay dividends when the material time savings are multiplied throughout the whole batch. The path you choose will determine just how great of a tool it can be for you. And while many companies believe and perpetuate the myth that AM is only a prototyping tool, innovators in a range of markets (e.g., aerospace, healthcare, consumer goods and more) are already using AM for production-grade manufacturing when design, performance and cost factors align. subtractive manufacturing or additive manufacturing techniques, various design features pose completely different challenges in both methods. A tip you can do with that is to use dovetail joints (there are different softwares that can help with that) and the dovetail joints will make sure that you have strongest cut and joint. Support material adds significant time to the printing process because every layer in the model needs to switch from model to support, but if we eliminate the support material we can actually increase our print time significantly. The path you choose will determine just how great of a tool it can be for you. The Additive Manufacturing Certificate is designed for professionals, engineering graduates or those seeking to enter the field of AM – 3D printing. Additive manufacturing has the potential to be a revolutionary addition to your traditional manufacturing capabilities and can be implemented in two distinct ways: either very poorly, or very well. Simon Indrele is a 3D Printing Application Engineer based out of Philadelphia, Pennsylvania and has been part of the Fisher Unitech family since 2017. High-speed mass production of metal parts, designed for the factory floor. One group of 3D printers I’d like to mention is the Stratasys F123 series, which is a group of well-rounded machines, which significantly improved throughput over the previous generation and has super simple to use GrabCAD Print software. In the clip below you can see a few use case scenarios of this. The MAS.500 Principles of Computational Design and Additive Manufacturing module will explore making through the lens of design, with a specific focus on designing for additive manufacturing. Bionic Wheel Carrier of Electric Vehicle – Automotive / Motorsports. So now we need to take that idea and flip it on its head because now the less material we use, the less cost and more time we save. The newest FDM material on the market is the. With additive manufacturing, the strategies used to produce a part change a number of important considerations and limitations previously faced … If you’re trying to do threading, I personally recommend not printing them because there are better ways to go about it. For example, if we use DFAM to lightweight a component, then that reduces material costs, decreases build time, lowers machine costs, and saves on pre-/post-processing, all of which lead to a much less expensive metal AM part when using laser … It has gone through tremendous improvements over the past few decades and has matured from simple prototyping to actual manufacturing and tooling. With a growing number of parts manufactured directly by additive manufacturing techniques, it is important to lay down design principles suitable for such manufacturing Hardware in 3D printers has improved to the point that it’s now rarely the bottleneck of performance. Design for Additive Manufacturing: Assembly Consolidation This is the final part in a seven-part series exploring how the principles of design for additive manufacturing (DfAM) can help unlock the many benefits made possible with metal 3D printing. This webinar will help you to understand the unique design opportunities associated with additive manufacturing, as well as the challenges. If you plan on reaming the hole, it’s great to add some extra contours to those holes so there’s actually more solid material. The impact itself is highest for production parts and lowest for rapid prototypes. Let’s take a look. Some of the new materials available include the. Design for Additive Manufacturing Training (Siemens NX) About this course The successful implementation of Additive Manufacturing (AM) requires a rethinking of design principles. Poorly-deployed additive is essentially just a replacement for traditional processes. Office-friendly production of metal prototypes and one-off parts. In practical exercises with the innovative 3D For example, if you have hot or abrasive issues with parts you can add bushings to those particular areas that are having contact issues. Some of the new materials available include the Nylon 12 Carbon Fiber which delivers the highest strength and stiffness-to-weight ratio of any Stratasys FDM material. One of the newest materials for the PolyJet line is called. So just be aware that as you’re doing that kind of segmentation, that you don’t go overboard. which is a PEKK-based FDM thermoplastic and is a high-performance material that is chemical resistant, possesses ultra-low outgassing properties, and exhibits high heat resistance making it well suited for aircraft and space applications. In the image below, the model on the left, if printed on FDM or SLA technology, could yield significant material and time savings if the bottom angle of the cuff feature was just changed 5 or 10 degrees. Batch production of fully dense, customer-ready metal parts. Yes, with new manufacturing methods and new software capabilities, a new paradigm in design philosophy is here: arise, design for additive manufacturing (DFAM)! , which is meant to simulate rubber material, so by its name and form it is a sturdy material but due to the fact that its PolyJet technology, rigid materials can be added to produce parts in a wide range of colors and Shore A values. For decades, manufacturability has been among the most important considerations - in some ways even more critical than form and function - in the design of metal and composite parts. Through hands-on experience participants will learn the principles, standards, materials and application of Additive Manufacturing. Different technologies require different optimization techniques which is important to keep in mind. One of the newest materials for the PolyJet line is called Agilus30, which is meant to simulate rubber material, so by its name and form it is a sturdy material but due to the fact that its PolyJet technology, rigid materials can be added to produce parts in a wide range of colors and Shore A values. However, if a couple of portions of the part were segmented away and printed separately significant time and material savings can be had. Additive Engineering is a key competence required to derive maximum value from the AM Technology. As well as being Stratasys Certified, Simon specializes in 3D scanning and reverse engineering. In summary, well-deployed DfAM requires not only skill but a new mindset. Design for additive manufacturing is one of the design methodologies that aims to optimize parts to meet the peculiarities of different AM technologies. In any case, the goal is always to minimize cost and maximize pro… Additive technology also enables DfAM principles by eliminating the need for hard tooling. 2. Again, it’s really flipping from subtractive manufacturing to additive manufacturing. This is the introduction to a seven-part series exploring how the principles of design for additive manufacturing (DfAM) can help unlock the many benefits made possible with metal 3D printing. So you’ll just take the existing parts that you currently design and then simply try to print them off. In summary, these principles offer different benefits for different fields, so based on whatever field you’re trying to improve you can go ahead and take a look at that specific principle. The newest FDM material on the market is the Antero 800NA which is a PEKK-based FDM thermoplastic and is a high-performance material that is chemical resistant, possesses ultra-low outgassing properties, and exhibits high heat resistance making it well suited for aircraft and space applications. There are many different types of hardware that can be added. This is the type of workflow you want to develop in your organization to make sure that Design for Additive Manufacturing is optimized well. This principle is a little interesting because it kind of goes against the original idea of “the less material we have the better.” If you’re printing with FDM technology that requires support material and you have a part like the one pictured below, that handle part will have support material throughout it. This normally doesn’t go well because essentially there’s no optimization or feedback. A well-deployed additive solution is thought of as a new tool for improving manufacturing aid functionality and cost. GrabCAD Print software allows for native CAD file import (no more messing around with STL files) as well as many other benefits. Rapid design exploration through real-time generative design. For this reason, it can also be supplier-specific, taking the capabilities of each supplier into account. Jigs and Fixtures: Changing the Factory Floor with 3D Printing, 3D Printing Support Material Removal and Surface Finishing Hardware, What to Look for in a 3D Printer: The Best 3D Printer by Industry. There are benefits of segmenting parts that do fit entirely in the printer. In the video example above, I demonstrate three ways to go about holes depending on the situation. A well-deployed additive will have a two-way street going all the way from management to operations and then all the way back. How you place a part on the printing bed will lead to some differences when … Data and Lifecycle Management in the Cloud, Stratasys 3D Printing: Honda Access Uses Prototypes for Accessory Customization, Objet30 3D Printer Helps Nicomatic Speed Delivery: A Case Study, The Revolutionary J55 3D Printer From Stratasys, SOLIDWORKS 2017: Every 3D Printing Feature. If you have any sort of magnets, rods, or other fixtures you want to put into a part, there are always some quick ways to put in some locating features in there so you can quickly snap and glue it in. If you’re spending engineering time to optimize a rapid prototype, one that you may only print just one or two of, the cost and benefit may not be significant enough to justify the time spend to optimize it. For instance, if your part is laying on its side, it will give it great strength and accuracy, however, if it’s laid flat it will yield the fastest print, and if you print it standing up, it will have the best appearance but will be the weakest part. The opportunity here is to create an educational and professional representation and design tool that helps designers learn and understand the principles of design with additive manufacturing. 3D printed parts are durable and inexpensive at low volumes.They can achieve previously impossible complex geometries, and, unlike injection molded or machined parts, they do not require any tooling or other start-up expenses. The design principles for additive manufacturing are different from conventional manufacturing methods. Note: You have to make sure that this does not become a traditional type of design for assembly process. Receive a weekly email with all the blog posts for the week. Design, development, and manufacturing of motor vehicles, Schools, colleges, universities and training centers, Design and manufacture of mechanical systems, Manufacturing aids, jigs, fixtures, and tooling. Abstract. For the model on the right, when printing in SLA or SLS technologies, providing escape holes in a hollow model reduces material usage drastically, while in FDM it would yield no benefits at all. Let’s take a look. With those extrusion lines, you can create some really lightweight but strong parts such as wing features. Additive Manufacturing (AM) is fundamentally different from traditional manufacture. In this blog, we’re going to touch on PolyJet and FDM (Fused Deposition Modeling) technologies. GrabCAD Print software allows for native CAD file import (no more messing around with STL files) as well as many other benefits. It rivals aluminum as far as mechanical properties go and so we’re seeing a ton of applications where it is replacing metal parts. Without the need to manufacture jigs, fixtures or molds, engineers and designers can go from design to functional part in as little as a day. Additive manufacturing isn’t as simple as hitting print, especially when using DFAM principles to design a part for industrial-grade quality while minimizing production costs. Let’s clarify what Design for Additive Manufacturing means and where the benefits really lie. After all, why build a machine part with 200 pieces when you can just print one in metal and forget about the whole assembly stage altogether. We will familiarize students with CAD software and computational design tools with which to create their own projects throughout the course of the module. But the resulting parts meet the performance of traditionally manufactured parts while reducing lead times, eliminating tooling costs and maximizing design flexibility. Design for Orientation. How you place a part on the printing bed will lead to some differences when it comes to your final part. One common example we see is that management sets a budget for engineering to get them the equipment and to start printing parts. Design for Additive Manufacturing. Contour designs mean that certain parts can be printed with just one or two extrusion lines. 3. The emergence of metal and composite 3D printing has brought with it a new design language - Design for Additive Manufacturing (DfAM) - developed to allow manufacturers take advantage of the enormous design freedom that comes with 3D printing. Additive Manufacturing allows a new degree of freedom in the designing of products, from lightweight structures to function integration, bionic and ergonomic designs. Stratasys has a large portfolio of FDM printers from the small but capable Mojo all the way to the F900 which is capable of printing 3’ x 2’ x 3’ – so there really is something available for everyone as far as material capabilities, build envelopes, and so on. Additive manufacturing is rapidly rewriting the rules of how metal parts are made, and it’s doing it with the help of a new design language - Design for Additive Manufacturing (DfAM). Most are well-acquainted with additive manufacturing (AM) — as a rapid prototyping tool, at least. The recorded webcast below focuses specifically on FDM. Most engineers today think “subtractively” because traditional manufacturing generally means taking a block of material and removing material from it. 1. The emergence of metal and composite 3D printing has brought with it a new design language - Design for Additive Manufacturing (DfAM) - developed to allow manufacturers take advantage of the enormous design freedom that comes with 3D printing. This is not very optimized and is a poor way to go out about it. The evaluation of the seven case studies highlights general design principles to take best advantage of the powder bed based additive manufacturing techniques Laser Beam Melting (LBM) and Electron Beam Melting (EBM). Design for orientation requires maximum communication between engineering an operations. More often, the shape of a part is the limiting factor of its performance. One group of 3D printers I’d like to mention is the, which is a group of well-rounded machines, which significantly improved throughput over the previous generation and has super simple to use. Just to reiterate something that I mentioned earlier, different additive manufacturing technologies require different types of DfAM optimization. Product manufactur i ng generally follows a tight schedule. Additive manufacturing — the use of 3D printers and comparable systems that do not rely on material removal techniques like cutting or etching. This book introduces the different types of AM technologies, categorised by liquid, solid and powder-based AM systems, the common standards, the trends in the field and many more. Some of the design strategies that can be used to address the idiosyncrasies of metal laser powder-bed fusion will be described and addressed in this article. In order to understand what DfAMy is and how it differs from DfAM, it helps to begin with the acronym that started it all: DfM. Even though additive manufacturing offers great freedom in shape and structural design, some restrictions need to … It rivals aluminum as far as mechanical properties go and so we’re seeing a ton of applications where it is replacing metal parts. Design for additive manufacturing (DfAM or DFAM) is design for manufacturability as applied to additive manufacturing (AM). Among the benefits of additive manufacturing this series will explore are: This is how DfAM is rewriting the rules of manufacturing design and creating next-generation parts and products. Design for Additive Manufacturing: Complex Geometry This is the first in a seven-part series exploring how the principles of design for additive manufacturing (DfAM) can help unlock the many benefits made possible with metal 3D printing. Main Gearbox Bracket – Aerospace. The MAS.500 Principles of Computational Design and Additive Manufacturing module will explore making through the lens of design, with a specific focus on designing for additive manufacturing. The MAS.500 Principles of Computational Design and Additive Manufacturing module will explore making through the lens of design, with a specific focus on designing for additive manufacturing. DfAM (Design for Additive Manufacturing) will be applied differently to different 3D printing technologies. Vivid Colors have been added to the Stratasys J750 3D printer which brings the color capabilities to over 500,000. I’ve often seen customers segment parts almost to an extreme and some of the benefits are actually negated. Together, they will allow citizen designers and SMEs to rapidly generate, prototype, and manufacture products. Iterate only the portions of the part you’re having problems with, for example, if you’re having a locking portion of a part break off and that’s the only portion that’s having issues, don’t keep reprinting that part over and over again just work on the tab features and the proper orientation. Additive manufacturing, also known as 3D printing, has rewritten the rule book for modern design and engineering.

There really needs to be a two-way street for DfAM to work properly. Additive Manufacturing has become a buzz word in today’s manufacturing world. To fully leverage the capabilities of AM, a new design approach is required. (Fused Deposition Modeling) technologies. A 3D print is no better than its design. Simon has over 13 years of experience in the 3D printing industry and has spent most of his career in production and application engineering. By ensuring parts are easy to produce, designers and engineers have reduced manufacturing costs for thousands of products, resulting in both lower prices for consumers and higher margins for manufacturers. 3D Printing and Additive Manufacturing: Principles and Applications is a comprehensive textbook that takes readers inside the world of additive manufacturing. 3D printing started in the 1980s and since then quite a few different technologies have developed. We will familiarize students with CAD software and computational design tools with which to create their own projects throughout the course of the module. We also recom-mend it for design and manufacturing courses, hobbyists, Maker clubs, and makerspaces. What if you have a part that is too big to print? However, in order to benefit from the inherrent opportunities of AM, it is necessary to quantify the fundamental attributes in comparison with traditional methods. Last month I discussed how Design for Additive Manufacturing (DFAM) is the value multiplier when it comes to additive manufacturing (AM). This is the first in a seven-part series examining how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a part’s function at the center of their design considerations. Want to learn more about designing for additive manufacturing? Stratasys has a large portfolio of FDM printers from the small but capable Mojo all the way to the F900 which is capable of printing 3’ x 2’ x 3’ – so there really is something available for everyone as far as material capabilities, build envelopes, and so on. a background on Design for Additive Manufacturing (DfAM) principles, the worksheet, and validation of the worksheet. We recommend this worksheet for companies that are considering or learning new AM processes, such as 3D printing. If you’re printing with FDM technology, usually, by default printers will print one or two perimeters around the hole and it will kind of raster fill the surrounding areas. In this unique seminar, the participants learn the production-ready design of 3D printed parts. Executing proper design for additive manufacturing techniques can increase yield and save time and costs when building your manufacturing process by ensuring that your 3D printers are used effectively. It’s a different thought process as far as manufacturing goes. For example, if you print a part that has a very light and sparse interior and you only have one or two contours, if you ream into those contours you’ll actually go into those hollow air gaps inside the part so you’ll reduce the structural rigidity of the part significantly. To see a real-world example of this, check out the video clip below. The integration of these functions into a new part as a matter of course is what RSC Engineering … Designing for manufacturability comes after the initial mechanical and/or electrical design, but before the design is released to the supplier for fabrication.
