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.

Aether and Procter & Gamble Begin Joint Development Project

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.

Researchers Use AI, 3D Printing & Bending Light for Numerical Calculations

Today, you will find 3D printers in the most surprising places—and all over the world. Not only that, but they are often busy doing the most surprising things for the human race. If you have been following 3D printing for even the shortest amount of time, then you may have learned to continually expect the unexpected. Machine learning and data calculations are perfect examples of this as they are now being applied in 3D via a new artificial intelligence system that performs its work through bending light.

AI is built on looping calculations of numbers and data that ultimately result in recognition. As UCLA researchers discovered, they can actually translate this into physical form through 3D printing with the accompaniment of light. Working with the premise of 3D printing that is built on layers, the researchers are able to make transparent diffraction patterns, ‘reflecting’ data in a neural network. Their work was recently published in a paper titled ‘All-optical machine learning using diffractive deep neural networks,’ by Xing Lin, Yair Rivenson, Nezih T. Yardimci, Muhammed Veli, Yi Luo, Mona Jarrahi, and Aydogan Ozcan.

“Deep learning has been transforming our ability to execute advanced inference tasks using computers,” state the researchers in their abstract.

They are able to establish this with a diffractive deep neural network, also known as a D2NN architecture—and one that is able to perform functions based on the collective diffractive layers.

“We create 3D-printed D2NNs that implement classification of images of handwritten digits and fashion products as well as the function of an imaging lens at terahertz spectrum,” state the researchers. “Our all-optical deep learning framework can perform, at the speed of light, various complex functions that computer-based neural networks can implement, and will find applications in all-optical image analysis, feature detection and object classification, also enabling new camera designs and optical components that perform unique tasks using D2NNs.”

The team used their unique learning model to recognize numbers that were written out by hand, afterward converting the matrix math into a data series related to ‘optical transformations.’ Each layer contributes to creating this data with the use of light, refocusing and adding values. This process involves millions of optical transformations on the 3D printed plates, with the system translating light into numeric values; in fact, the researchers report that with the 3D-printed D2NNs they are having a 90 percent success rate!

While the process is still being refined by the research team, it could be relevant to numerous applications in the future due to the flexibility of such calculation tools. It could be used to read letters instead of numbers too, as well as offering facial or other types of physical recognition.
