Help me make my objects warp! I am looking for suggestions for a test object which is prone to corner curling. I've had this happen on a few objects like this one (http://www.thingiverse.com/thing:662862), not very badly, but enough to be annoying. So now I'd like to find an object that I can print quickly and is likely to distort in the same way, so I can quickly experiment with some remedies for fixing it. This is with PLA on blue painters tape at 195/185, bed 70, 0.4mm first layer, 0.3 thereafter, though that's not directly related to my question. https://reprap.org/forum/read.php?262,524974,524974#msg-524974 Sat, 08 Aug 2026 12:52:22 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,524974,525974#msg-525974 Re: Help me make my objects warp! https://reprap.org/forum/read.php?262,524974,525974#msg-525974 Sounds interesting.

One thing I noticed is that the thicker your layer heights the more a part tends to warp.
Having said that, lowering the speed for the first 4 or 5 layers also helps me in such cases.
It gives the plastic more time to cool down and get into shape.
Once the lower layers have cooled down enough so the print won't warm them up the parts are usually fine.
Have you tried a circuit board?
I mean the big blank ones for etching your own circuits?
Using plastic primer on the copper side give a nice, flat surface and parts stick like mad, especially if you used a steel cleaning pad on the copper first.]]> Downunder35m Printing Tue, 23 Jun 2015 22:27:09 -0400 https://reprap.org/forum/read.php?262,524974,525247#msg-525247 Re: Help me make my objects warp! https://reprap.org/forum/read.php?262,524974,525247#msg-525247
Also, I remember reading that when using painter's tape heating the bed actually lowers adhesion, though I've never tested that myself.]]> AlexY Printing Tue, 23 Jun 2015 14:19:38 -0400 https://reprap.org/forum/read.php?262,524974,525238#msg-525238 Re: Help me make my objects warp! https://reprap.org/forum/read.php?262,524974,525238#msg-525238

Here's one of the parts for a 3D printer I'm designing—so far it's been extremely prone to warping and also doesn't use that much plastic, so it would be a good piece to test with.

Looks great - thanks! I'll try it tonight.]]> animoose Printing Tue, 23 Jun 2015 13:54:49 -0400 https://reprap.org/forum/read.php?262,524974,525218#msg-525218 Re: Help me make my objects warp! https://reprap.org/forum/read.php?262,524974,525218#msg-525218 AlexY Printing Tue, 23 Jun 2015 13:04:08 -0400 https://reprap.org/forum/read.php?262,524974,525199#msg-525199 Re: Help me make my objects warp! https://reprap.org/forum/read.php?262,524974,525199#msg-525199 Floyd Printing Tue, 23 Jun 2015 12:06:28 -0400 https://reprap.org/forum/read.php?262,524974,524974#msg-524974 Help me make my objects warp! https://reprap.org/forum/read.php?262,524974,524974#msg-524974
