This looks very interesting. Print the higher temp plastics without a heat bed and with good adhesion. https://www.thingiverse.com/thing:1911919
From the description he's printing on denim or other cotton-based fabric. Interesting. How is he adhering the fabric to the bed? Is that getting glued down, just set in place, clamped down, etc? How does he level his bed? The description leaves more questions than answers.
I'd like to see how well that holds up to a large ABS print. Wouldn't be surprised to see the print peel itself right off or peel the fabric off the tape. The power of the warp is strong. I'll stick to my heated bed and my PEI and mickey mouse ears.
Sorry, but I'm with Nick on this one. Might not be bad with a heated bed, but I wouldn't trust plain textile for a large ABS print. I'd also like to see the underside of the first layer. Bet you it has lots of fibers sticking out of it. Not exactly appealing...
