How to Smooth Polypropylene Prints

Hi there,

I’m brand new to 3D printing, but once I get some practise I plan on printing PP parts using a Bambu Lab X1 Carbon. From what I’ve read, I understand that PP is tricky to print with and also difficult to get a nice finish on.

I’m curious if I can smooth off PP parts using sandpaper or chemicals or is there some other finish which can be applied to improve the appearance of parts?

I would really appreciate any advice as I’m a complete novice. Thanks!
