Inside the Enable Community Foundation’s (ECF) prosthetic challenge with Andreas Bastian

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.

Challenge helps NASA pack for Mars

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.

Behind the scenes with Alcoa & the bearing bracket challenge

After receiving an overwhelming number of entries for our GrabCAD Challenge, Alcoa Fastening Systems & Rings (AFSR) quickly set forth evaluating each design using a systematic approach. PH15-5 material properties were applied to the parts to determine their mass. We then placed each design within the given part envelope to ensure the requirement was met. The entries that did not meet the part envelope were not considered further. As a next step, we evaluated the stress under both load conditions using FEA.

Evaluating 3D printed parts – if you can, show off the part

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.

How can you generate 170 product design ideas in a few weeks? GrabCAD Challenges.

There are a number of ways to design a new product. You can ask your designers. You can hire a design agency. Or, you can sponsor a GrabCAD Challenge and ask 1.8 million members for help. Last year, AirPatrol challenged our members and got over 170 new ideas for their wireless controller. That product recently launched and I asked Daniel Dordett, CEO and Andre Altjoe, Business Development at Airpatrol about this new way to design consumer electronics.

GE seeks open innovation from the GrabCAD Community

Today we launched another great GrabCAD Challenge with GE. I talked to Lisa Ralph, Open Innovation Leader & Global Strategy at GE, about this Challenge to give you more details on their engineering problem, so you can create the best entry possible. This Challenge, ending March 9, has a prize pool of $10,000. The winners will be announced by June 8, after thorough testing and evaluation.

NASA Challenge seeks fresh ideas for the ISS

GrabCAD is incredibly proud to host the Handrail Clamp Assembly Challenge with NASA. NASA has been investigating 3D printing technology in space for some time now and this Challenge is another great milestone. GrabCADrs are invited to submit fresh 3d printable handrail clamp ideas for the International Space Station (ISS). I asked Niki Werkheiser, In-space Manufacturing Project Manager at NASA to reveal a bit more about the the background of this Challenge.

Introducing GrabCAD Challenges for 2015

Today we launched our first GrabCAD Challenge of 2015. This challenge will help build a better solution for a self-service parcel delivery system. We chose this engineering problem to begin the year based on what members said we could do to improve the GrabCAD Challenge experience: solve real problems, help others, and build skills.  In 2015 we plan to do just that.
