Cabine temperature for ABS powder sintering/welding?
October 22, 2015 05:34AM
Hi folks,

I have read the article in the reprap wiki where it is stated that the laser power is less important if the cabine or the powder bed is heated sufficient.

[www.reprap.org]

It is saying that nylon powder is heated until about 8 degrees below melting point. I am in the process of building a SLW/SLS printer and I would like to try with ABS.
Can someone tell me how much the cabine or the powder needs to be heated with ABS powder?

Regards,
Markus

... as most warping is received while cooling down from 50degC to roomtemp, I'll heat the chamber only for 55 to 60degC and use a laser with more power than 140mW winking smiley ... so the build chamber materials and nearby parts didn't suffer from overheating ...
