Updates from RAPID + tct in Pittsburgh, PA

This year, SME hosted the RAPID conference together with Rapid News Publications Ltd., and combined their nearly 30 years of insights and experience. It was the biggest showcase yet and the new machine highlights were the launch of the Studio printer line by DesktopMetal, the reveal of the printer from Impossible Objects and a new nano-metal and nano-ceramic printer by XJET.

Here are some product highlights seen at the showcase:

Projects in our Additive Manufacturing course (ME514) this spring semester

As the semester is coming to an end, the final presentations for our “Additive Manufacturing” class are done and I want to share some highlights with you.

The students worked in groups of 5-6 on multiple 3D printing projects for about 8 weeks.

Here you can see images of the final prototypes of a 3D Bucky figurine with moveable ball joints and a finger rehabilitation device for stroke patients. More information about all the projects can be found here: http://additive-mfg.me.wisc.edu/

News from AMUG2017 in Chicago, IL

There are a lot of new technologies on display that either just came out or will be launched soon.

  • Admatec, who is know for their ceramic printer is presenting their new metal printer: a slurry filled with metal particles is cured with DLP technology layer by layer, the resulting green part is then sintered in an oven.
  • Metal X from Markforged will be released in 6 month. It prints with metal-filled thermoplastic filament, followed by a debinder and sinter process
  • Vader will start selling their printers in about a year. They are using Magnetojet technology to print their parts.
  • Voxel8 is working on a new printer for multi-materials. Their focus is still on conductive inks, as the 3D antenna array shows.
  • The server cooling units from our friends at ebullient (http://www.ebullientcooling.com/) were highlighted in the Carbon showroom. Ebullient is a startup out of UW Madison.
  • Carbon also showed now new materials like their polyurethanes (EPU) to print flexible lattice structure.
  • HP had their new multijet fusion printers running to produce parts 10x faster than SLS processes; they are only focusing on black parts for now to help with the energy absorption, but they are working on full color.

Additive Manufacturing @ IMTS2016

The International Manufacturing Technology Show (IMTS) – has partnered with Local Motors to offer the IMTS Ride Experience featuring the breakthrough technology in “Olli,” the first self-driving electric and 3D printed bus equipped with IBM Watson Internet of Things (IoT) technology.

Built by Local Motors, Olli can carry up to 12 riders with 25 mph. For show purposes the speed was limited to about 5 mph. Olli uses the cloud-based cognitive computing capability of IBM Watson to analyze and learn from high volumes data produced by more than 30 sensors embedded in the vehicle, including cameras, GPS and LIDAR (Light Imaging, Detection, And Ranging). Learn more about Olli here…

The second highlight was presented by Stsratasys. They showcased their new Infinite-Build 3D Demonstrator and a Robotic Composite 3D Demonstrator to present their vision for additive manufacturing. Infinite-Build turns 3D printed parts on their side to deliver large, lightweight thermoplastic parts with repeatable mechanical properties. Parts grow horizontally out of the chamber for practically unlimited height. The Robotic Composite 3D Demonstrator consists of a printhead mounted on a 5-axis robot that prints on a tilting and rotating table. Thus, it works without support material, which maximizes build speed and reduces post-processing labor and lead time. Learn more about these two new technologies here…

3D-printed parts could be hot new technology for keeping power plants cool

The University of Wisconsin and its partner Oak Ridge National Laboratory are developing enabling technologies for low-cost, high-performance air-cooled heat exchangers. The objective is to develop a high-thermal conductivity polymer composite filament that can be used in additive manufacturing (3D printing) to produce the high-performance heat exchanger design. Due to the design freedom enabled by additive manufacturing, the team plans to develop 3D heat exchanger geometries that optimize heat transfer and decrease the total footprint required for an air-cooled system. Both of these innovations could enhance air-side heat transfer and improve the efficiency and cost of heat exchangers.

Advanced 3D printer sparks new campus collaborations

Kuo K. and Cindy F. Wang Professor Tim Osswald, co-director of the Polymer Engineering Center (PEC), says the lab’s 3D printer—a selective laser sintering (SLS) machine, purchased with funding from a $1.5 million gift from alumnus Robert Cervenka and his wife, Debbie—has been instrumental in forging creative projects involving people from various disciplines who might not typically work together.
