Traditional design processes don’t work with AM, so it’s changing (Authentise Weekly News-In-Review – Week 81)

We’ve set up our design process to be efficient and reliable for the tools at our disposal, and with 3D printing, it’s about time to shake it up. 3D printing is inherently different from traditional manufacturing techniques and, to explore its true potential, we need to rely on design tools that help us explore new directions. Sandia Labs argues that this technology doesn’t plug easily into established production methodologies, both in terms of speed and how the variables involved impact the parts. The different features of a 3D printed part are a challenge for precision manufacturing lines. Apart from industrial compatibility issues, to see where we can push 3D printing we need to think outside the box. Concepts like 4D manufacturing help us envision what we can achieve with the technology, with parts that react to temperature, light or mechanical changes. This is nothing new in and of itself, but it’s been explored through 3D printing and it’s empowered design capabilities. We are already on the right track to reinvent the design process through smart digital tools, like generative design and quick iterative cycles, and the future looks exciting.

Sandia Labs Focused on Optimizing Design for 3D Printing

3D printing is capable of streamlining both design and production processes, but most designers (and many design tools) aren’t really prepared to take advantage of the design possibilities the technology presents. Traditional design methods applied to additive manufacturing don’t necessarily lead to fully optimized designs. Sandia National Laboratories’ Laboratory Directed Research and Development project hopes to point the industry in the right direction.

According to Sandia, the project focused on “how to put less precise 3D printed parts together with precise tools, taking advantage of the rapid prototyping, design and manufacturing possible with additive manufacturing.”

MIT engineers create 3D-printed magnetic shape-shifters

Engineers from MIT have designed soft, 3D-printed structures that can transform their shape “almost instantaneously” with the wave of a magnet. The magnetically manipulated objects are made using a type of 3D-printable ink developed by researchers at the Massachusetts Institute of Technology (MIT), which has been infused with tiny magnetic particles.

Week in Review: September 19th to 26th – AM Materials’ Expansion

Hello, welcome to another week in review brought to you by Authentise.

This week got a lot of buzz going for breakthroughs and materials bringing excitement to the world of AM: we got 3D printed cemented carbide tools courtesy of Fraunhofer Institute for Ceramic Technologies’ (IKTS) new binderjetting technique, bioengineered plastic spitting bacteria to supply future space missions and a whopping AM breakthrough in flexible thermoelectric devices which promises plummeting prices for coming IoT clothing and more.

Let us begin.

 

Fraunhofer IKTS develops 3D printed carbide tools with adjustable mechanical properties

Fraunhofer IKTS will present 3D printed cemented carbide (hard metal) tools at the World PM2016 Congress & Exhibition… IKTS scientists used a binder jetting 3D printing method to produce the tools. According to the researchers, these 3D printed tools are of comparable quality to those produced using conventional methods, and can be made into more complex shapes.

Nano Dimension paves way for wearables by 3D printing conductive patterns onto fabric

Israeli PCB 3D printing pioneer Nano Dimension has just successfully 3D printed conductive patterns made from silver nanoparticles onto specially treated fabric. This achievement, realized in collaboration with an unnamed leading European functional textiles company, paves the way for sensors and electronics that are actually part of your clothing. It proves that even functional and ‘smart’ fabrics, packed with sensors, are realistic possibilities and do not need to be limited by movement, folding or wearing.

Research explores thermoelectric screen printing

In work led by professor Yanliang Zhang at Boise State University, high-performance and low-cost flexible thermoelectric films and devices were fabricated by an innovative screen-printing process that allows for direct conversion of nanocrystals into flexible thermoelectric devices. Based on initial cost analysis, the screen-printed films can realize thermoelectric devices at 2-3 cents per watt, an order of magnitude lower than current state-of-the-art commercial devices.
