Farsoon 3D Printing Pure Copper

Pure copper heat exchanger

Two years ago, after Farsoon Technologies had introduced its metal laser sintering system, the company’s application team began working with industrial partners to develop an advanced 3D printing process that could additively produce components made of pure copper. Copper is a soft, ductile metal with both high electrical and thermal conductivity, and it’s often used in industries like shipbuilding, electronics, automotive, and aerospace. But most additive copper is based on alloys, and not the pure metal itself, which is hard for lasers to regularly and continuously melt and can cause problems like thermal cracking and interface failure.

That’s why Farsoon’s work is important – all of its metal laser sintering systems can successfully create cost-effective, high-quality pure copper parts. The company’s process and unique parametric design is able to meet custom needs of customers, and to date, it’s launched 13 process parameters for metal powder sintering, including pure copper. Some of the parts that have come out of Farsoon’s recent collaborations include a pure copper heat exchanger, which featured a 0.5 mm wall thickness, complex spiral geometry and was printed in a single piece. Farsoon is open for additional partners seeking to further develop the 3D printing of pure copper and other specialized materials.

San Francisco 3D bioprinting startup Aether has entered into a two-year joint development agreement with Procter & Gamble (P&G) in order to develop 3D printing and artificial intelligence technologies. The two will use the multi-material, multi-tool Aether 1 3D printer as a technology creation platform, and will create several hardware and software capabilities that hope to automate and improve P&G’s product research applications and develop a next-generation Aether 3D printer. An interconnected network of computer vision and AI algorithms aims to increase automation for multi-tool and multi-material 3D printing, while high-performance cameras will enable new robotics capabilities. Aether is also working on additional software that will help P&G automate and speed up image processing.

“Aether is working with P&G to completely redefine 3D printing.  It’s no longer going to be just about depositing a material or two in a specific pattern. We’re building something more like an intelligent robotic craftsman, able to perform highly complex tasks with many different tools, visually evaluate and correct its work throughout the fabrication process, and constantly learn how to improve,” said Aether CEO and Founder Ryan Franks.

DyeMansion Names New UK Distributor

3D print finishing systems distributor DyeMansion, headquartered in Munich, announced that Cheshire-based 3D printing services supplier Europac3D will be the UK distributor for its range of machines. Per the agreement, Europac3D will now offer all of the AM finishing systems in DyeMansion’s Print-to-Product workflow, which includes its Powershot C powder blasting system, DM60 industrial coloring system, and the PowerShot S, which delivers homogeneous surface quality to 3D printed, powder-based plastics. Because of this, Europac3D is one step closer to achieving its mission of being a one-stop shop for 3D printing, scanning, and post-processing services.

“DyeMansion’s post-production systems are worldclass and add the all important finish to additive manufacturing,” said John Beckett, the Managing Director of Europac3D. “Their systems are perfect for companies or 3D print bureaus that have multiple SLS or HP 3D printers and allow us to extend our offer by providing market leading additive manufacturing finishing systems for 3D-printed polymer parts.”

New 3D Printing ‘Best Practices’ Book

We could go on and on about the many benefits offered by 3D printing (and we do), but there are still industry executives who remain unconvinced when it comes to adopting the technology. But a new book, titled “Additive Manufacturing Change Management: Best Practices” and released today, is here to provide some guidance for those still holding back. The book, which addresses some of the challenges of adopting 3D printing, was published by CRC Press as part of its Continuous Improvement Series and written by Dr. Elizabeth A. Cudney, an associate professor of engineering management and systems engineering at the Missouri University of Science and Technology, along with Divergent 3D’s VP of Additive Manufacturing Michael Kenworthy and Dr. David M. Dietrich, who is an Additive Manufacturing Engineering Design Fellow for Honeywell Aerospace and Dr. Cudney’s former doctoral student.

Dr. Cudney said, “If company leaders are interested in bringing additive manufacturing online, this book can help them decide if it makes sense for their industry.

“There’s often a lack of planning, a lack of understanding, a resistance to change and sometimes fear of the unknown. Our hope is that this book will provide a good road map for managers to advance additive manufacturing at a faster pace.

“We wanted to take a look at how companies can roll out a new technology, new processes and equipment and integrate that in such a way that you have a good product in the end.”

In the 17-chapter book, the authors present what Dr. Cudney refers to as a ‘road map’ for business leaders looking to adopt 3D printing. The eBook format costs $52.16, but if you want that shiny new hardcover version, it will set you back $191.25.

3D Printing News Briefs: October 7, 2018

We’ve got a shorter edition of 3D Printing News Briefs for you today. Siemens Corporate Technology is working on process simulation for additive manufacturing. BIOMODEX is launching a realistic, 3D printed new training product, and an orthopedic surgeon is using 3D printing to repair bone fractures. Finally, several companies are collaborating and using metal 3D printing to make a customized component for the upcoming Ironman race.

Siemens Working on 3D Printing Process Simulation

Often in metal 3D printing, all kinds of defects can occur, such as distortion and local overheating. Getting the 3D print right the first time around is the goal that experts of Siemens Corporate Technology are working to achieve. Process simulation for additive manufacturing is a pretty important step on the way to industrializing the technology, as getting complex geometries correct at the beginning of the process could save time and money down the line.

“Our vision is to develop this additive manufacturing process in such a way that we can actually print a model created in the CAD system, getting it right the first time and printing it perfectly,” said Ursus Kruger of Siemens Corporate Technology in Berlin. “We call this the first-time-right principle, which we want to achieve here.”

BIOMODEX Launching New 3D Printed Training Product

The Left Atrial Appendage Closure Solution (LAACS) station

With the launch of its new training product, medical technology startup BIOMODEX is officially entering the interventional cardiology space. Its new Left Atrial Appendage Closure Solution (LAACS) lets physicians work on their skills using a super realistic, 3D printed multi-material heart. The startup’s patented INVIVOTECH technology makes it possible to create 3D printed organs based on a patient’s medical imaging, like CT scans. It’s also possible to reproduce an organ’s surrounding tissue and biomechanics as well.

“Our mission is to provide as realistic an experience as possible for physician training,” said Carolyn DeVasto, the Vice President of Global Commercialization at BIOMODEX. “Our advancements in patient specific 3D printing using INVIVOTECH and ECHOTECH allow physicians to train in a clinical setting using the same techniques they use in an actual procedure.  Ultimately, we want to provide the physicians an opportunity to test drive any procedure on our solution to improve safety and clinical outcomes.”

BIOMODEX’s patented ECHOTECH also allows physicians to observe the 3D printed heart using fluoroscopy, or any TEE ultrasound system. This means that they will be training with the same techniques they’ll be using in real life procedures, which is invaluable in the operating room.

Repairing Fractures with 3D Printing

Nathan Skelley, MD, an orthopaedic surgeon and sports medicine specialist at the Missouri Orthopaedic Institute, is working on a research project about a specific issue related to trauma orthopaedics – reducing and fixing bone fractures.

“In the United States, we’re very fortunate that I have an almost endless supply of plates and screws,” Dr. Skelley said. “I’ve never been in a situation in the OR where I don’t have another screw or I don’t have another plate to fix one of these fractures. But in the developing world or in rural environments, those resources are not always the case.”

Dr. Skelley and his team are testing if they can easily replicate the plates, screws, and tools they use so often in these types of common trauma and sports procedures with 3D printing, so physicians in areas not quite as developed as the US can perform necessary orthopaedic surgery. You can learn more about his work in the video below:

Metal 3D Printing for Ironman World Championship

Next week, the Ironman World Championship, a yearly culmination of several Ironman triathlon qualification races held around the world, begins in Hawaii. For this particular race, Canyon, Swiss Side, and Sauber Engineering are working together on Project 101 for Patrick Lange, last year’s Ironman World Champion. The goal is to make the Lange, the fastest Ironman, even faster, by using metal 3D printing to fabricate a customized aero cockpit that fits Lange’s arm shape and position perfectly. CFD (Computational Fluid Dynamics) simulations were used to confirm that his tri-bar extensions were producing a decent amount of drag, so the project partners worked out a design to integrate them into Lange’s arms.

Swiss Side 3D printed the first concept and tested it back in May, and Lange’s arms were scanned at Sauber to ensure the perfect fit. Canyon and Swiss Side designed and optimized the aerodynamics for the new aero cockpit, and using FEM (Finite Element Method) structural analysis, the parts were optimized for weight and stiffness. The most recent iteration was 3D printed in plastic and tested in another wind tunnel session so Lange could approve its performance. Then, Sauber used titanium to 3D print the final parts; aluminum was used to create ultra-light shells for the elbow pads.

“While working on Project 101, we did something that has never been done before in triathlon,” Lange said. “I am very proud to be part of this project. We tested my new aero cockpit in the wind tunnel and the results confirmed a significance performance improvement. This will have a direct impact on my bike-splits in Kona. I can’t wait to show the world my new aero cockpit and deliver a strong performance on October 13th at the big race in Kona, Hawaii.”
