Glass point of PETG is around 70C, glass point of ABS is around 105C. ABS is significantly better against heat.
Good news, then. Edge + Scaffold could be a really useful combo for me, if Edge has the heat tolerance of polyesters you’ve used.
My bad @Ryan_Carlyle is right. It will do better than PLA but I’m not sure by how much.
PLA has a glass temperature of about 60C.
PETG is “good enough” as far as heat resistance goes, it doesn’t have the issues PLA does. 70-75C is pretty hot. It also has the other benefit of generally being flame retardant (self-extinguishes upon removal of ignition source, unless blended funny) whereas ABS is pretty flammable if you can get it burning (450C or so).
@Jeff_Parish Virgin PLA used for things like beverage cups is 55-60C Tg, but the stuff we use for filament has different additives and usually runs 50-55C. It does vary with blend though.
Yes. That is why I said “about”. The PLA I’m using seems to be right at 60C but there could be a 5 degree error with heat loss through the bed and such so it is likely close to the range you mention for 3D printer filament.
@Dale_Dunn well there is something against pla. Its not very temperature stable. At least use petg or something. But Iam away from that too. Pla. Lol.
@Ewan_Talbot …is there any reason you think “lol” adds to this completely unfunny discussion? Why post? Are you some sort of bot?
@ThantiK LOL, troll much? People post because it is a public forum and they wish too.
@Gary_Craig Nope…a single word response seems awful spammy…and G+ has it’s fair share of bots. He’s just keeping the conversation on-topic.
@Gary_Craig , you think as the creator of this community that I have some sort of habit of trolling people’s posts? This guy looks like the kind of bot spam we’ve been getting lately.
@ThantiK Probably not, no. But I didn’t look at who said it, I was looking at the comment. The comment seemed a bit rude and trolling to me. Maybe something was funny to the person, maybe it was a bot as you suggest.
