i am building a corexy 3d printer with a heated build chamber . so i need a gt2 belt which can easily withstand operating temperature of 80C/175F. Do you have any recommendations?
which is better at withstanding high temperatures? neoprene rubber or polyurethane?
what belts do existing 3d printers with heated build chambers(like stratasys) use?
i have never made/used a heated chamber printer before but i think the belts may survive 80C. if you want to be sure you should probably put them outside of chamber as also motors and electronics are not very happy at 80C.
@Cristian_Nicola all motors except the extruder motor is outside the heated build chamber, the direct extruder and hotend is water cooled.
the only way to i can think of to isolate belts from heat is to use bellows like in many stratasys printers .

Genuine Gates belt is rated for 85°C and a more rigid (not-stretchy) belt anyway. I can’t say anything for no-brand or otherwise non-Gates.
@Jeff_DeMaagd beat me to it. By the way Stratasys has a patent for moving the electronics outside the heated part of the chamber and they like to sue people
@Adam_Steinmark Have they ever sued individual builders?
@Preston_Bannister I couldn’t find any info on actual lawsuits but I recall them sending a cease and desist letter to some hobbyist. I don’t remember the details, they might’ve been putting up a Kickstarter for the printer or just publishing an Instructables for it.
