Hey guys, I’ve just completed my first prints. The top surfaces and sides came out really good, but the undersides came out a little rough. Especially where supports were, what’s the accepted standards for cleaning these areas up? Sandpaper, files, dremel?

What settings should I be looking at to make my next prints even better in these areas?

My setup: Qidi xplus3 Sunlu PLA + 2.0 (using its default filament profile in orca) @ 230/60 300blkfde’s orca/machine settings. 12 walls, 80% infill. Layer height: .2 Support distances: .19

I appreciate the feedback!

That looks pretty good!

If you decide to sand it, don’t do it too much and wear a mask. The particles that result from that sanding aren’t great.

There are some acetone based approaches too.

Personally I just don’t try to clean it up more than that, and if you really need the part to be pristinely clean, I prototype myself and then buy a final print from a professional 3D printing company.

I’ll post a pic of the top and sides cus I feel they turned out really good for my first go. Was just a bit put off by the undersides and support surfaces. These will just be range toys and to have fun projects to work with. Nothing serious enough for a professional print. That’s cool though, didn’t know you could do such a thing.
