If your Z offset is too high, the filaments will stretch and warp. If it’s too close, it’ll squish them. A level print bed will help the filaments stick and keep the print from warping.
Make sure you don’t apply too thick of a layer or the print won’t adhere to it. Wipe off the glue with a damp cloth in between prints to remove the residue.
You could also use a specially designed print bed spray, such as 3DLac to coat the surface.
When you’re finished printing, peel off the painter’s tape and wipe down the print bed with a damp cloth to remove any residue.
You can pull off the brim from your print when it’s finished. Many 3D printers have a brim option you can select so your printer will make one on the print bed.
You can pull off the mouse ears when your print is done.
You could also cover the entire 3D printer with a cardboard box large enough to allow enough room for all of the moving parts in the printer to work unimpeded. [8] X Research source
Avoid adjusting the thermostat in the room while you’re printing as well.
If you’re able to control the speed of your fans, you can also try setting them to a lower speed for the first few layers to help create a more solid and consistent foundation.
You need to reduce the nozzle temperature as well so the hot tip doesn’t melt or warp the plastic.
You can find heated print beds at some electronic stores, 3D printing shops, or online. Make sure they’re compatible with your printer! Many filament manufacturers will list the recommended print bed temperature on the packaging so you can set it so it’s just right.
