Flat surface deformation troubleshooting after 3D printing?

[garylhk]

How to prevent first layer flat surface deformation? the base rectangular cylinder is 99 X 78 X 5mm.

Thank you!

This looks like warping. It’s probably that the environment you have your printer in is too cold. A first step would be to make sure you have no drafts near your printer (is that an air conditioning outlet I see right behind it?). Another possible simple solution would be to just put a cardboard box over it while printing (i.e. a $5 “enclosure”), but then you have the dilemma of either not being able to see your prints or having to spend a bit more on building a window (but hey, even a cellophane window cut into a cardboard box would work just fine probably for PLA).

Thank you!I will try this solution

Addressing environmental factors like temperature and drafts can help reduce the risk of warping in 3D prints. Placing the printer away from potential sources of cold air, such as air conditioning outlets or drafts, and maintaining a stable room temperature can create a more favorable printing environment. Additionally, using a simple enclosure, such as a cardboard box with a transparent window, can help maintain a consistent temperature around the printer. Monitoring the printing process closely and adjusting as needed can help achieve the desired results.
