General question about steel sheet texture

Hi there,

I have a textured steel sheet that I like very much, but I noticed that the texture is noticeably coarser than the one that has apparently been used to print my printer's parts. Are there different kinds of textured sheets?

Cheers
Gert

Hi,

 

Yep. My textured sheet is a 4King sheet. It has a pretty fine texture to it.

There was chatter some time ago that they switched manufacturers of the textured sheets, apparently due to quality control.

Yeah, I have a "thekkiinngg v2" sheet that I imagine is similar to yours(?). (Couldn't wait for the Prusa sheets to become available back then). Unfortunately it seems to be not perfectly even - small prints work fine, but large prints suffer from differing first level thickness, as if the coating on the metal sheet has a varying thickness. It's still nice and I like the texture for some applications, but quality-wise the Prusa sheet that I have is clearly superior.

Regarding the grain of the surface, my printer's original parts seem to be somewhere between my Prusa sheet and the thekkiinngg sheet.

I remember that - it sounded like it was quite a pain for Prusa to get a reliable supplier/process.
Would be interesting to know if the printed parts of newer printers have the coarser surface texture too, or if they use different sheets in-house.

Hi,

I  bought mine 2 months ago. I've not had any issue with it and I have printed some larger PETG stuff on it without issue. I suspect a QC issue maybe responsible for your problems. 3rd tier products can be iffy for quality sometimes. I might have just gotten luckier than you.
