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.

Grabby Goes Mobile

Grabby is going mobile! Hello everyone, my name is Andrew and I’m the mobile developer here at GrabCAD. I want you to bring GrabCAD with you, wherever you go. We are working on getting our mobile apps out to you but first we need your help.

Help me make a GrabCAD mobile app that works for you, fill out my quick survey

GrabCAD wants to be a part of your workflow. People are increasingly using their mobile devices more than their desktop computers, so we want to be there when you get that flash of inspiration or simply have to share an idea with someone on the move. A mobile app will strengthen our 3D viewing experience and make it easier for members to communicate and browse. We would love to hear your thoughts about GrabCAD mobile applications. Feel free to drop me a line with your suggestions!

End of the week update to our site

 GrabCAD is taking the level up a notch again and going through an upgrade today. We are making changes to the website that hopefully everyone will benefit from and that will make the browsing, downloading and managing your CAD models and projects much more convenient.

We have scheduled all the necessary work to take approximately 2 hours, starting in a moment, and we will keep you posted about the progress.

UPDATE: the site is again up and running. You can read about the changes we did and the reasons behind it here.

Also, to keep you all entertained meanwhile, lets roll some conversation in the comments - any links or stories about interesting engineering projects that are going on anywhere in the world?
