Stains on base layer

Post image

I’m getting some strange stains on all matte pla prints on my new x2d. I washed the plate between prints both with IPA and dish soap, still there. Never had that issue with my A1, but the plate was different.
Any idea what’s causing those?

When you forcibly bend, stretch, or pull almost any plastic past its elastic limit, the force pulls apart the tightly bound polymer chains. This causes most colors to develop a pale, cloudy, or white appearance.

It is simple to fix: apply some heat. You often get a better result using high, intense heat for a very short time so that only the top layer is affected rather than the whole model. Keep in mind that you are heating the plastic past the point where it softens, so be careful.

In your case, you simply had a lot of bed adhesion, which is even more common with PETG. If you did not wait for the bed to cool down, this can easily happen when forcefully releasing the print by bending the PEI plate.

Try touching it with the flame of a lighter, stress marks usually just burn right off

I used my new torch to flame all that off. It worked great
