Introducing the Stratasys J826 – Full-color, multi-material printing for the enterprise design world

Taking risks attempting to capture design intent at the end of the process requires a lot of post-processing (coloring, assemblies, a mix of technologies, etc.) – when its too time consuming, expensive and late to make changes or correct errors. Stratasys PolyJet 3D printing technology is developed to elevate designs by realizing ideas more quickly and more accurately and taking color copies to the next level.

By putting realistic models in a designer’s hands earlier in the process, companies can promote better decisions and a superior final product. Now, with the Stratasys J8 Series, the same is true for prototypes. This tried and tested technology simplifies the entire design process, streamlining workflows so you can spend more time on what matters –creating, refining, and designing the best product possible.

PADT is excited to introduce the new Stratasys J826 3D printer 

Based on J850 technology, the J826 supplies the same end-to-end solution for the design process and ultra-realistic simulation at a lower price point.
Better communicate design intent and drive more confident results with prototypes that realistically portray an array of design alternatives.

The Stratasys J826 3D Printer is able to deliver realism, shorter time to market, and streamlined application thanks to a variety of unique attributes that set it apart from most other Polyjet printers:

  • High Quality – The J826 can accurately print smaller features at a layer thickness of 14µm to 27µm. As part of the J8 series of printers it is also capable of printing in ultra-realistic Pantone validated colors.
  • Speed & Productivity – Three printing speed modes (high speed, high quality & high mix) allows the J826 to always operate at the most efficient speed for each print. It can also avoid unnecessary down-time associate with material changeovers thanks to it’s built-in material cabinet and workstation.
  • Easy to Use – A smooth workflow with the J826 comes from simple integration with the CAD format of your choice, as well as a removable tray for easy clean up, and automated support creation and removal.

Are you ready to learn how the new Stratasys J826 provides the same quality and accuracy as other J8 series printers at a lower cost?

Provide the requested information via the form linked below and one of PADT’s additive experts will reach out to share more on what makes this new offering so exciting for the enterprise design world.

Mars, Hearts, Spaceships, and Universities: 2019 Colorado Additive Manufacturing Day a Success

Engineers, educators, and enthusiasts gathered on the green lawn of beside the Platte River at the Blind Faith Brewing to talk about Additive Manufacturing. Over 170 attendees (and two dogs) met each other, caught up with old colleagues, and shared their AM journey during the breaks and listened to 13 presenters and panelists. 12 antipasto platters and 30 pizzas were consumed, and 298 beers or sodas were imbibed. By the numbers and by type of interaction we saw, a successful event all around.

This was the fourth annual gathering, hosted by PADT and sponsored by our partners at this brewery. We could not have put this event on without the support of Stratasys, ANSYS, ZEISS, and Desktop Metal. We also want to thank our promotional partners, Women in 3D Printing and Space for Humanity who both brought new people to our community. Carbon, Visser and a student project with Ball Aerospace did their part as exhibitors.

Check out the Slideshow at the end of this post to get a visual snapshot of the day.

We want to thank the true stars of our event, the speakers and panelists who shared their knowledge and experience that turned a great gathering into a learning experience.

We started the morning off with an inspirational keynote from Dr. Robert Zubrin. A visionary in the space community and long term champion of going to Mars, Dr. Zubrin shared with us his observations about the new space race with his talk: “The Case for Space: How the Revolution in Spaceflight Opens Up a Future of Limitless Possibilities.” He left the packed audience energized and ready to do our part in this next step in humanities exploration of the universe. He stayed after to talk with people and sign copies of his book, which you can find here.

We then heard from user David Waller of Ball Aerospace on his experience with their Desktop Metal system. He went over the testing, lessons learned, and usage of their Studio system. It was a great in-depth look at someone implementing a new technology. There is a lot of interest around this lower-cost approach to producing metal parts, and the audience was full of questions.

Sticking with the Desktop Metal technology, PADT’s very own Pamela Waterman talked about how PADT is using our in-house Zeiss Optical Scanning hardware and software to inspect the parts we are making with our Desktop Metal System. She shared what we have learned about following the design guidelines that are developing for this technology and how scanning is a fast and accurate way to determine the final geometry created in the three-step process of building a green part, debinding, and sintering.

Next up was Christopher Robinson form ANSYS, Inc. to talk about recent additions to the ANSYS Additive products. He shared how customers are using simulation to design parts for metal powder bed fusion AM and then model the build process to predict and avoid failures as well as compensate for the distortion inherent in the process. The key takeaway was that simulation is the solution for getting parts built right the first time.

After a short break, and some AM trivia that won some PADT25 T-Shirts for people who knew the history of 3D Printing, we heard all about the new V650 Flex Stereolithography system that Stratasys recently introduced. Yes, Stratasys now makes and sells an SL system and it is literally a dream machine designed by people with decades of AM and Stereolithography experience. Learn more about this open and powerful system here.

Another AM technology was up next when Nick Jacobson spoke about Voxel Printing with PolyJet technologies. He discussed how he varies materials and colors spacially to create unique and realistic replicas for medicine and engineering. He also showed how the voxel-based geometry he creates can be used to create Virtual Reality representations of objects. Much of their work revolves around the visualization of hearts for adults and children to improve surgery planning. While we had been focused on space at the start of the afternoon, he reminded us of the immediate and life saving medical applications of AM.

And then we moved back to space with a presentation from Lockheed Martin‘s Brian Kaplun on how they are using AM to create parts that will fly on the Orion Spacecraft. Making production parts with 3D Printing has been a long-term goal for the whole industry, and Lockheed Martin has done the long and hard work of design, test, and putting processes in place to make this dream a reality. One of the biggest takeaways of his talk was how once the Astronauts saw a few AM parts in the capsule, they started asking of its use to redesign other tools and components. The ultimate end-users, they saw the value of lightweight and strong parts that could be made without the limitations of traditional manufacturing.

We finished up the day, after another break and some more trivia, with a fascinating panel on AM at Colorado’s leading Universities. We were lucky to have Ray Huff from Wohlers Associates moderate a distinguished group of deans, directors, and professors from four outstanding but different institutions:

  • Martin Dunn PhD,  Dean of Engineering, CU Denver
  • Jenifer Blacklock PHD, Mechanical Engineering Professor – Colorado School of Mines
  • David Prawel PhD, Director, Idea-2-Product 3D Printing Lab, Colorado State University 
  • Matt Gordon, PhD,  Chair, Mechanical Engineering, University of Denver 

Their wide-ranging discussion covered their education and research around AM. A common theme was industry cooperation. Each school shared how they use AM to help students not just make things, but also understand how parts are made. The discussion was fantastic and ended far too soon, which is always an indicator of a great group of experts.

And that sums up our great day, leaving out several hundred side conversations that went on. Check out this slide show to get a feel for how energetic and interesting the afternoon was.

As everyone left, some reluctantly and after one more beer, the common comment was that they can’t wait to get together again with everyone. We hope that next year we will have more speakers and participants and continue to support the growth of Additive Manufacturing in Colorado.

A quick note about the location: You are not wrong if you remember a different name for the three previous events. St. Patricks’s is now Blind Faith and the new owners could have not been more welcoming. Plus, they have more Belgian’s, which I am a big fan of.

Video Interview: Topology Optimization versus Generative Design

While attending the 2019 RAPID + TCT conference in Detroit this year, I was honored to be interviewed by Stephanie Hendrixson, the Senior Editor of Additive Manufacturing magazine and website. We had a great chat, covering a lot of topics. I do tend to go on, so it turned into two videos.

The first video is about the use of simulation in AM. You should watch that one first, here, because we refer back to some of the basics when we zoomed in on optimization.

Generative design is the use of a variety of tools to drive the design of components and systems to directly meet requirements. One of those tools, the most commonly used, is Topological Optimization. Stephanie and I explore what it is all about, and the power of using these technologies, in this video:

You can view the full article on the Additive Manufacturing website here.

Video Interview: 3 Roles for Simulation in Additive Manufacturing

While attending the 2019 RAPID + TCT conference in Detroit this year, I was honored to be interviewed by Stephanie Hendrixson, the Senior Editor of Additive Manufacturing magazine and website. We had a great chat, covering a lot of topics. I do tend to go on, so it turned into two videos.

In the first video, we chat about how simulation can improve the use of Additive Manufacturing for production hardware. We go over the three uses: optimizing the part geometry to take advantage of AM’s freedom, verifying that the part you are about to create will survive and perform as expected, and modeling the build process itself.

You can read the article and watch the video here on the Additive Manufacturing website. Or you can watch it here:

If you have any questions about how you can leverage simulation to add value to your AM processes, contact PADT or shoot me an email at eric.miller@padtinc.com.

For the second interview, we focus on Topological Optimization, Generative design, and the difference between the two. Check that out here.

PADT Adds the Faster, Larger and More Advanced Stratasys F900 Fused Deposition Modeling Additive Manufacturing System at its Tempe Headquarters

The F900 is the Most Capable System on the Market for Companies Who Need Large, 3D-Printed Production Parts in Small or Large Volume

TEMPE, Ariz., August 29, 2019 ─ In an exciting development that enhances its additive manufacturing services and capabilities, PADT, a globally recognized provider of numerical simulation, product development, and 3D printing products and services, added a Stratasys F900 Fused Deposition Modeling (FDM) Additive Manufacturing System at its headquarters in Tempe, Arizona. With fast build speed and large build volume, the F900 significantly increased PADT’s 3D Printing capability and capacity.

“The addition of the F900 flagship FDM printer to our growing lineup of additive manufacturing systems is a major milestone in our long-term partnership with Stratasys,” said Ward Rand, co-founder and principal, PADT. “This move greatly enhances the capabilities we provide our customers based on Stratasys’ leading-edge equipment.”

The Stratasys F900 is specifically built for manufacturing and aerospace. With the largest build size of any Stratasys FDM system, it’s designed to handle the most demanding manufacturing needs. The system uses a wide range of thermoplastics with advanced mechanical properties so parts can endure high heat, caustic chemicals, sterilization and high-impact applications.

FDM is the most common additive manufacturing process because of the technology’s ability to provide robust parts quickly at low-cost. PADT has developed expertise with the FDM printing process over the past 20 years. The Stratasys F900 is the pinnacle of FDM technology because it’s designed to meet the needs of the manufacturing industry’s shift from prototyping towards production parts. The addition of the F900 comes at a critical time for PADT due to the increased demand from its customers in industries such as aviation, space and defense, to create end-use components created under ISO9001/AS9100 standards.

“When we added a large stereolithography machine in 2018, we quickly learned how significant the demand is for more materials, larger parts, and faster turnaround,” said Rey Chu, co-founder and principal, PADT. “The Stratasys F900 fulfills all three of these same requirements for companies who need the outstanding performance of parts made with the FDM process. We look forward to partnering with our customers to make innovation work with this new capability.”

This new system will augment PADT’s existing fleet of four FDM systems from Stratasys.  It will compliment Stereolithography, PolyJet, Selective Laser Sintering, and Digital Light Synthesis systems. This wide range of material and process choices is why hundreds of companies rely on PADT as their Additive Manufacturing services provider.

National Renewable Energy Laboratory

The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) focuses on advancing the science and engineering of energy efficiency, sustainable transportation, and renewable power technologies, including marine energy. When it comes to developing the components of a wave energy device that produce power from relative motion induced by the dynamics of ocean waves for example, NREL’s research requires extensive validation before it is ready for commercialization. This process often includes generating sub-scale components for numerical model validation, prototypes for proof of concept, and other visual representations to provide clarity throughout the entire manufacturing process. It’s also important to accurately validate research projects at a more manageable and cost-effective scale before moving beyond the prototype stage.

Recently, NREL has ventured into building parts with more complex geometries, such as 3D printing hydrodynamically accurate models that are able to effectively represent the intricacies of various geometry and mass properties at scale.

PADT Awarded U.S. Army Phase I SBIR Grant for Combustor Geometry Research Using 3D Printing, Simulation, and Product Development

The Project Involves the Development of Sand-Plugging Resistant Metallic Combustor Liners

TEMPE, Ariz., August 15, 2019 ─ In recognition of its continued excellence and expertise in 3D printing, simulation, and product development, PADT announced today it has been awarded a $107,750 U.S. Army Phase I Small Business Innovation Research (SBIR) grant. With the support of Honeywell Aerospace, PADT’s research will focus on the development of gas turbine engine combustor liners that are resistant to being clogged with sand.  The purpose of this research is to reduce downtime and improve the readiness of the U.S. Army’s critical helicopters operating in remote locations where dirt and sand can enter their engines.  

“PADT has supported advanced research in a wide variety of fields which have centered around various applications of our services,” said Eric Miller, co-founder and principal, PADT. “We’re especially proud of this award because it requires the use of our three main areas of expertise, 3D printing, simulation and product development. Our team is uniquely capable of combining these three disciplines to develop a novel solution to a problem that impacts the readiness of our armed forces.”

The challenge PADT will be solving is when helicopters are exposed to environments with high concentrations of dust, they can accumulate micro-particles in the engine that clog the metal liner of the engine’s combustor. Combustors are where fuel is burned to produce heat that powers the gas turbine engine. To cool the combustor, thousands of small holes are drilled in the wall, or liner, and cooling air is forced through them. If these holes become blocked, the combustor overheats and can be damaged.  Blockage can only be remedied by taking the engine apart to replace the combustor. These repairs cause long-term downtime and significantly reduce readiness of the Army’s fleets.

PADT will design various cooling hole geometries and simulate how susceptible they are to clogging using advanced computational fluid dynamics (CFD) simulation tools. Once the most-promising designs have been identified through simulation, sample coupons will be metal 3D printed and sent to a test facility to verify their effectiveness.  Additionally, PADT will experiment with ceramic coating processes on the test coupons to determine the best way to thermally protect the 3D printed geometries.

“When we developed new shapes for holes in the past, we had no way to make them using traditional manufacturing,” said Sina Ghods, principal investigator, PADT. “The application of metal additive manufacturing gives PADT an opportunity to create shapes we could never consider to solve a complex challenge for the U.S. Army. It also gives us a chance to demonstrate the innovation and growth of the 3D printing industry and its applications for harsh, real-world environments.”

Honeywell joined PADT to support this research because it is well aligned with the company’s Gas Turbine Engine products. The outcome of this research has the potential to significantly improve the performance of the company’s engines operating in regions with high dust concentrations.

This will be PADT’s 15th SBIR/Small Business Technology Transfer (STTR) award since the company was founded in 1994. In August 2018, the company, in partnership with Arizona State University, was awarded a $127,000 STTR Phase I Grant from NASA to accelerate biomimicry research, the study of 3D printing objects that resemble strong and light structures found in nature such as honeycombs or bamboo.
