This week stories include a laser sintered Kickstarter sensation Nighthawk wallet, raising well over its initial goal, a man who 3D printed an insulin pump for a little diabetic girl's American Doll, and a 3D printed skateboard design from My Mini Factory. Two companies report new finishes for 3D printed items. Shapeways has introduced a glossy resin coat for its full color sandstone prints, and i.Materialise offers a new unpolished black steel finish. If you'd like to try it out, you are in luck because printing steel has gone down in price there by 16%. Last but not least, Hackaday provides a new solution to the printbed heat-up problem by using aerogel as insulation.
