ProJet 3500 HDmax Printer is up and running

This summer we got the new ProJet 3500 HDmax from 3D Systems up and running.  It features exquisite detail in a range of materials.  We’ve already used it for some turbine and microfluidic prototypes.  Contact Dr. Hewlin or Dr. Williams to discuss prints on this machine.

Hydrovision 2019, Portland State University, and Portland

Hydrovision was in Portland,OR this year, which made attending a no brainer as I coupled visits to Portland State University on the front and back end of the conference to oversee the assembly of the hermetically sealed magnetically geared generator for marine hydrokinetic energy applications.  The conference itself was a good chance to connect with industry, government, and academics in the search for the next partner, supplier, or funding source.  It was particularly exciting to see Emrgy (a small business out of Atlanta) announce a new partnership with GE Renewables to bring their small distributed hydro generators to international markets.

The time at PSU was also valuable to supplement the countless video conferences over the past year.  I was impressed/amused to see the electronic component vending machines in the halls of the Engineering building.  As quirky as it seems, I can imagine them getting a lot of traffic, particularly during senior design crunch time.

The city itself remains a favored destination, with reliable mass transit, great choices for food, and inspiring attractions.

Manufacturing Support for Solar Racing at Appalachian State

The Magnetic Gearing Research Group was happy to provide some manufacturing support to Appalachian State University’s Team Sunergy as they made modifications to their car ROSE (Racing On Solar Energy) in advance of their upcoming races.

We were able to use the Haas Mini Mill to produce new battery holders.

App State students visit to assist with manufacturing.

Microhydro Workshop at Appalachian State

I got to head up the mountain in early June to Appalachian State University for a workshop on covering the principles, practice, and lessons learned with microhydro power.
