As a Stratasys applications engineer, I spend my days intimately involved with our technology. It’s exciting to design complicated parts and push the limits of the technology. When designing for 3D printing, you need to keep in mind a couple key factors to improve the quality of your builds.
The Enable Community Foundation (ECF) challenges the GrabCAD community to lend a hand and take part in a challenge to create a 3D printed terminal device for those with limb differences. The ECF and the e-NABLE community believe that limb differences should never serve as barriers towards living a fulfilling and extraordinary life.
NASA’s Advanced Exploration System (AES) Division’s Logistics Reduction Project is trying to decrease the dependence on earth resupply for future long duration space missions. This is done via direct mass reduction, re-purposing logistics, and conversion of waste into useful by-products (gases, water, solids). We are trying to pack everything for Mars but our suitcase is too full. So we need to be smart about what we take, how we maximize the use of those items, and create new uses for the items once they’ve met their original purpose.
Like all GrabCAD Challenges, the Oxygen Valve Splitter Challenge presented a difficult problem: create an oxygen valve splitter that allows for independently controlled flow rates. As the valve splitter is meant for “low-resource environments,” participants had to design their part with certain considerations in mind (speed, minimal post-processing, and printability on a basic FDM machine). In addition to earning the top prize, the winning part has the potential of saving lives.
With over 130 designs submitted, our large panel of judges worked hard to determine the winning entries. While in the ideal world all Challenge participants would have been able to test their designs by printing them out, it is understandable that not everyone has access to a 3D FDM Printer just yet. Luckily, some of the judges including Victoria Au (3D4MD) and Adam Arabian (Assistant Professor of Mechanical Engineering, Seattle Pacific University) were able to print out the finalist entries to test the devices. Here, Andrzej Stewart at the Hi-SEAS IV mission, explains the methodology his team used to evaluate entries.
I want to take a minute to express my sincere thanks to everyone for submitting proposals to our challenge. It will be difficult to make a final selection but I wanted to comment in general about the intended use of the part and offer some a few points to consider.
RoboSavvy is looking for help from the GrabCAD Community! They are gathering fresh ideas for the design of a new humanoid robot built to teach and entertain. This design Challenge will help them to launch a new open-source humanoid robot that will be affordable, attractive, agile, and smart.
Get inspired to create new, inventive bike accessories for the Velodroom product line! Their current lighting system, watch this video, is smart and practical, they start when you start and stop when you stop. They rear light even turns on when you brake. What would you create in Velodroom style for the daily bike commuter?
GrabCADr Extraordinaire Tommy Mueller has been working closely with our team to promote and experiment with GrabCAD's collaborative tools. The latest experiment has been to challenge everyone to develop a Pod-racer (remember Star Wars Episode I?). 34 collaborators have put in hours and hours of work over the last month to produce their own creation. Now the voting begins! Tommy has created an off-site voting tool so that all 470,000 of you can check out the submissions and vote. Click here and get your vote in before February 22!
