What is the difference between STL and OBJ files and which one should I use?
STL is the de facto standard in consumer-grade 3D printing. It is a bare-bone format that describes the shape of the object by defining the coordinates of all the vertices of all triangles that a ...

What is the point of diminishing returns on the STL refinement level in Fusion 360 on an Ender 3?
I don't know that this can be definitively answered for a specific printer and all arbitrary designs.
The refinement level basically determines how smooth a curved surface will turn out. The STL ...
