I have a BCN3D Sigma for a printer and I was wondering about the square lines on the round part of the fillet. I was wondering if this is a limitation in the printer or if this is an STL problem. I use solidworks to make my parts and export them as STL’s to print. I’m also using Simplify3D as my Slicer.
That’s an STL thing. Surfaces in STL files are made up of triangles, so curves are approximated with flat surfaces. You can either set the output resolution higher, so it produces more polygons in the STL, or open this STL in another program and subdivide the existing triangles to get a closer to truly round shape.
Ok cool thats what I thought the problem was but figured I would ask. Thanks for the response. Ill up the resolution in Solidworks for my STL’s
It’s almost a good thing in a way. The fact that you can see the faceting, that the faces aren’t lost in the noise, among other things, means the machine is probably nicely tuned. And the face edges aren’t blobbed either, in a pretty good balance. My guess is you’ll probably want to maybe triple the resolution of the output.
Not exactly stl thing. You can set the output accuracy generating a larger but less blocky file from Sw when saving selecting export options, increase resolution, experiment!
Tested that out and wow it prints like a new machine. All the faces are coming out really nice now. Thanks for the info and making my print quality better
Wow, you’ve tested it out in two minutes after the comment? Fast printer 
Haha I started it 8 hours ago lol I new how to change the res and stuff but never changed it from what solidworks had as default
I use a different CAD program but I set my “angle” to 2 degrees. It might be slightly more than necessary but I personally think it’s worth using to avoid the visible faceting.
