So I had an old scanner lying around just begging to be dismantled, and I finally had some free time to do just that. And I turned up trumps with some uncracked glass ^_^ But at the moment my printers running PLA onto blue painters tape, not a particularly nice bottom finish, but it does the job. So I was thinking, with exams coming round within the month, I haven't got enought time to make a full heated bed config and fit it. So is it possible to just simply plop the glass straight onto the bed with a couple of bulldog clips and a quick wipe with some acetone? Would the PLA stick? I mean the heat has no real factor in stickiness does it? Just to stop warping of large parts? Which I'm not really doing at the moment :v) Ollie. https://reprap.org/forum/read.php?1,130533,130533#msg-130533 Mon, 20 Jul 2026 03:39:09 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,130533,153080#msg-153080 https://reprap.org/forum/read.php?1,130533,153080#msg-153080 xiando General Fri, 07 Sep 2012 23:56:43 -0400 https://reprap.org/forum/read.php?1,130533,153041#msg-153041 https://reprap.org/forum/read.php?1,130533,153041#msg-153041 George W Childs General Fri, 07 Sep 2012 17:58:13 -0400 https://reprap.org/forum/read.php?1,130533,131443#msg-131443 https://reprap.org/forum/read.php?1,130533,131443#msg-131443
Either way, I use picture frame glass that was custom cut to my size and it sticks very well for small-med size parts (about the size of a prusa x-carriage)

Anything bigger and I need to use masking tape. The nice part of glass however, is the nice glossy surface it leaves on the part, so I try to when convenient.]]> TheIrrationalDevotion General Sat, 05 May 2012 02:25:52 -0400 https://reprap.org/forum/read.php?1,130533,130739#msg-130739 https://reprap.org/forum/read.php?1,130533,130739#msg-130739
just poor some onto the glass, and wipe off excess. let it dry for 5 or ten minutes.

on large heated objects the parts pop off the bed when cooled, i think from the glass size changing.


, for parts that are not heated, just twist and part will come loose.]]> jamesdanielv General Mon, 30 Apr 2012 05:27:17 -0400 https://reprap.org/forum/read.php?1,130533,130736#msg-130736 https://reprap.org/forum/read.php?1,130533,130736#msg-130736 I had good results with cold surface using frosted glass and spray adhesive.

The parts stick great and when cooled they crackle and pop right off with a nice glassy finish.

before I had a heated bed I was printing on wood with masking tape.]]> aplavins General Sun, 29 Apr 2012 16:40:02 -0400 https://reprap.org/forum/read.php?1,130533,130590#msg-130590 https://reprap.org/forum/read.php?1,130533,130590#msg-130590 theodleif General Sun, 29 Apr 2012 05:39:40 -0400 https://reprap.org/forum/read.php?1,130533,130585#msg-130585 https://reprap.org/forum/read.php?1,130533,130585#msg-130585 -------------------------------------------------------

Then you must be better at calibrating than me. If my heated bed drops below 40C everything snaps off if the head catch on the part ever so little. If I start the print with too low bed temperature, the beginning of the skirt doesn't stick to the platform and drags everything off at the first or second layer.

Perhaps sanding the glass, extruding at higher temperature, printing slower and using lift could help?

Not saying OP shouldn't try it if he wants, but in my experience it won't be more reliable than masking tape or acrylic.]]> Nudel General Sun, 29 Apr 2012 05:25:29 -0400 https://reprap.org/forum/read.php?1,130533,130584#msg-130584 https://reprap.org/forum/read.php?1,130533,130584#msg-130584 -------------------------------------------------------

Gimme a month and I'll make one. Exams take priority unfortunately :/
