3D Printer Policy, Materials and Charges

Last updated 07.29.2014


The CU Community Fab Lab provides 3D printers as a service during open hours. Lab rental is available as an option for people who need consultants to make 3D designs for them.

If a print fails due to machine problems (filament tangle, power loss, extruder clog, etc...) we will reprint it for you free of charge. If a print fails due to inproper support, structural design or poor choice of material we will print it again for the regular charge.
