Help Using an enclosure caused warping issues

[mknielsen10 0]

I recently completed building an enclosure for my 3D printer and now every print has major warping issues. When the printer was sitting out in the open, in my living room, I rarely had issues with warping. The warping gets worse as the infill density increases. One model of about 100 layers and 50mm x 25mm printed fine until the last few layers and then it warped. I have tried:

• increasing the bed temp from 60C to 65C
• using a glue stick
• Slowing the initial layer print speed to 25mm/s

 

I understand the reasons for warping of parts in general, but why do I have such a huge problem now that I am using an enclosure?

Some more information and a picture of your setup would be good.

What material are you printing?

What is the print temperature?

What printer?

Are you sure the bed is heating uniformly?

Is the enclosure equipped with an exhaust fan?

See the recent topic on "theory on warping", or something like that, where we discussed possible causes. I guess your environment is way too hot now, and the print stays soft and peels off.

What kind of material you are using is the big question of course.

 

PLA for example got proven by multiple people to be more prone to warping in warm build-chambers. For this material a more decent room temperature like 21°C with 100% cooling fan is better.
