Hi folks,
I have 2 questions.
0.05mm layer height and these MUST be printed perpendicular to the plate
Firstly, I’m getting some banding on my prints. I believe this corresponds to where the “floor” of the print is completed and the walls begin (and/or the difference in peel forces?). I’ve attached some pictures - is there a setting I can change to help eliminate this? This is a prototype for a premium a client is going to sell and the banding is a non-starter.
The 2nd part of my question is in regards to removing the “dimples” caused from the LPU from prints which are perpendicular to the build plate. I thought about reducing power on the top surfaces, but I’m not sure if that would make a difference. If I can get these settings file tuned, we’ll have an awesome product. Any thoughts on this?
@DasPrintHaus I’m sorry to hear that you’re having some print quality issues. I’ll do the best I can here, but the best way to get to the bottom of all of the issues is to open a support case.
I can say that the dimpling is the release texture. The best way to resolve this is to change the orientation. However, I know that you can’t for this model. The other suggestion we have from our engineers is to print with a higher layer thickness (100um if not already), or greatly increase squish waits in the Print Settings Editor
Thank you for the response! I will open a support case for the banding. I’ll also play around with the squish waits.
A few things happening here, and I’ve seen this all too frequently myself.
Layer banding like that can be really bad when there are sudden cross sectional area transitions. This is due to bulk material shrinkage. Printing flat on BP usually exacerbates this problem.
The dimples are caused by the LPU and will show on any parallel surface. Both are actually a huge annoyance as people start to print more and more direct on BP and the FL engineering team is well aware of this issue (I’ve raised it multiple times to multiple people).
For now, the only workarounds I’ve done are:
- Don’t print flat (I know, not helpful)
- Texture the surfaces - this works very well but your part will obviously be…well…textured
- Change your design if you have design freedom

Thanks for the reply!
I think the texture option might be the trick. This is a product that is printed in FDM and I’m trying to make a premium resin version WITHOUT a huge redesign. But, here we are 
The dimples weren’t a huge issue, that’s just me trying to tweak all the everything’s and figured I might save some time if someone had already figured it out.
Most of what I do is hobby resin stuff and have spent years dialing in settings, supports, angles etc on anycubic machines but I’ve only had the form4 since December. I like to know the nitty-gritty of each machine, what each setting does and how to print the best possible product. I don’t want people getting things injection molded overseas when domestic options exist.
Anywho, thanks again!
Yeah I’d go with texturing then. I’ve done this on parts myself to work around the same issues. Texture on both surface will solve both of your problems.
Unfortunately the texture engine is a bit finicky and there’s some trial and error…so you’ll have to just play around with it. I’m not sure if the latest Preform update with the “real view” rendering actually does a better job of rendering what the texture will look like but maybe?
Man, if they had edge detection like Bambu Studio for surface texturing, we’d be in such a good spot.
