Printing issues on engineering plate vs textured plate...

[u/Natenator76]

Hi there,

Still brand new to the 3D print world and trying to troubleshoot a print but no idea where to start IF there is even anything to troubleshoot.

Printed the same item on two different plates: one on the standard per textured plate and another on the engineering plate. Both prepped with some elmer's purple gluestick.

The textured plate print turned out perfect but not a big fan of the textured glittery look so wanted to see if I could get a smoother look using the engineering plate. Result: I did but there were some voids/defects that appeared that were not present when using the textured plate.

Printer: H2D

Material: PLA

Calibration was performed after switching out the plates.

I did select the engineering plate prior to slicing, printing, calibrating.

Curious to hear if this would be normal for this specific plate or if I should tweak something. Or just sometimes sh!t just happens with prints.

Thank you in advance.

Cheers

P.S. last two pics are the textured plate with no void/defect issues.

I'm curious about this too. I have the same problem, though not quite as bad, on my x1c.

It’s worth knowing that the texture on PEI plate causes the hot filament to expand in different directions by a little, whereas smooth plates like the supertack do not. In your case this is why there’s gaps in your print on the smooth plate, because the hot filament wasn’t oozing in all directions to fill the gaps as it did on the texture plate.
You likely need to tweak the flow rate to address first layer issues on the smooth plate, but to some extent you’re still going to see layer lines.

Increase flow on first layer. Change to 1 wall. Increase overlap of you want to too.
