3D Printing News Unpeeled: Wasteful 3D Printing & Robot Tails

A photo on Reddit of a user making a color 3D printed model and getting 15 times the amount of waste has sparked a mini debate. But, with a 1000 layer 44 hour print for a few inch model with single nozzle purging on many layers it seems like this is a model no one would normally print.

Research at the University of Alberta is using the heating of the nozzle to make 3D printed food safer. Julia Barsukova looked at how heating the nozzle could kill Salmonella enterica serovar Typhimurium. 

 Chandler Cheng has made an Augmented Limb that is meant to be an aid for zero gravity maneuvers for astronauts.
