Marvel Universe Live and e-NABLE asked the Dallas Makerspace and Polyprinter to join their event printing prosthetic hands for children.  

e-NABLE is a volunteer community of designers who print low-cost hands for children. You can join their cause and even print a hand for a child in your area: http://enablingthefuture.org/get-involved/. 

The Dallas Makerspace is an awesome non-profit community workshop who organized the 3D printers for the event. 

Marvel brought the stars, Dallas Makerspace brought the PolyPrinters. Everyone had a great experience.
