I haven't tried it myself, but read here that Nylon and other filaments are often hard to make them stick to the print bed. This is, because we are looking for a bed surface that holds the part while printing, but popps off, when cooled down. One idea is to print on a surface that really bonds with the part and when done, using a hot wire to cut it off the bed. Or use a sheet of Nylon to print Nylon. The sheet would then be the bottom of the part and can only be used once. https://reprap.org/forum/read.php?262,808948,808948#msg-808948 Mon, 12 Oct 2026 04:39:10 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,808948,809662#msg-809662 https://reprap.org/forum/read.php?262,808948,809662#msg-809662 o_lampe Printing Sat, 10 Feb 2018 08:24:59 -0500 https://reprap.org/forum/read.php?262,808948,809584#msg-809584 https://reprap.org/forum/read.php?262,808948,809584#msg-809584
Possibly a thin film though. A sheet of something like 6mil nylon would be thin enough not to completely sink the heat from the extrusion, nor insulate the extruded layer from a heated bed, but should still be thick/strong enough to hold the printed layer in place if it's clamped firmly down outside of the print area. (Googling 'nylon film' also results in a thermal adhesive version which sounds like it may fit the bill even better.)

All bets are off when the nylon starts to shrink though, since the film will not provide much effective resistance to that. Curling might be a real problem since nylon can shrink more than twice as much as ABS.]]> SupraGuy Printing Fri, 09 Feb 2018 14:31:51 -0500 https://reprap.org/forum/read.php?262,808948,809564#msg-809564 https://reprap.org/forum/read.php?262,808948,809564#msg-809564 Srek Printing Fri, 09 Feb 2018 11:42:05 -0500 https://reprap.org/forum/read.php?262,808948,809406#msg-809406 https://reprap.org/forum/read.php?262,808948,809406#msg-809406
What about making up a nylon base that is held onto the print bed via some mechanical system, clips maybe.
This could be a marketed that can be cut down to bed size if needed, perhaps 1mm thick precision piece....

This would be cut back after printing on it.....]]> JustSumGuy Printing Thu, 08 Feb 2018 11:32:22 -0500 https://reprap.org/forum/read.php?262,808948,808948#msg-808948 https://reprap.org/forum/read.php?262,808948,808948#msg-808948 This is, because we are looking for a bed surface that holds the part while printing, but popps off, when cooled down.
