Easy model hard to print?

Can anyone help me with the right settings for the model below?


I cannot get de outerwall smooth. And the bottom inside looks also bad.
Printed with new petg and pla.
I printed another print (not round) with a thin wall and this looks perfect.

Has it to do with the larger diameter or the combination with the overhang?

I am planning to print more scale models of vessesl and tanks, etc.
So i’m trying to find what i am doing wrong.

Some help would be great.

If that is Bambu Silver, ther are some settings to change:

Yes this is Bambu pla silver and the green is Bambu petg.
I don’t see any settings?

That’s my response on that post about silver PLA. I tried the suggested values and they made the print look bad. I changed it back to the default, prints look good again. I did not try it with the bronze. It may work for you, my silver is a year old by now.

If the cup shape is only 1 wall thick, there may not be a way to print it cleanly, it may have been intended for resin printing which can do walls that thin. The following comments are just me thinking out loud. You could slow the printer way down, say in the 40-70 mm/s range. Print at the smallest layer height your current nozzle can go. Switch to the smallest nozzle your printer supports. If it’s 2 or 3 walls try setting Quality/Advanced/Order of walls to inner/outer/inner. You may also have to play with temperature.

The settings are in the post above mine. It says choose a silk profile or change volumetric flow to 15 mm/s.

I’ve changed the support type and the wall thickness and looks much better now.

I don’t like the thick seams, is there a way to change this?

You could try the “Seam: Scarf” setting. That is an experimental setting which is providing very nice results in reducing seams.

Scarf is the answer.

I usually randomize the Z seam so I don’t get a big unified seam defect. Tried scarf for the first time last week on a print where I forgot to randomize the Z seam. I know which corner of the print was chosen by the slicer for the seam. Cannot detect it visually. The print effectively has no seam. Good stuff.

Hi Avonet
So did you ONLY changed the model and support types to get theses result ? It lools way better!

Yes, i changed the thickness of the walls and used “close-fitted” support.
