Polypropylene Bed Adhesion

The other issue with adhesion is the greater the difference between the extruder temperature and the bed the poorer adhesion. There are other things can help with this. … A slower extrusion speed allows the extrusion to cool more before getting as long of a length to for the contraction force; thus improving adhesion. …

Irregular adhesion on Creality glass bed

I haven't seen lifts that aren't on the edge of the print, such as warping, or the entire printed surface lifts. When I get something like in your photograph, it's because the print surface isn't fla …

How to remove ABS from PEI Sheet

Heat up your bed to the print temperature; maybe even as hot as 100 °C. This will soften the ABS and make it easier to scrape off. It will distort a print to remove it this way, but is good for clea …

What's causing my PLA prints to lift like this?

Use a higher extrusion temperature for the first layer to promote adhesion. (Differences in PLA composition could cause these temperatures to vary.) … Sometimes it helps to have an bed temperature for the 1st layer as high as 75 °C to promote adhesion. …
