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/

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).

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…
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.

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.
