If you plan on getting into 3d printing, you must understand that there is a balance between print fidelity and print time. Most printers can print objects at really fine detail, often times making it difficult to see any layer lines. But printing this detailed can add hours to a print. Even then, if you plan on painting your piece for say, a prop or a detailed model, you’ll have to hide the layer lines in order to get an accurate replica.
I use a combination of three different products to help hide 3d printed layer lines; the first is a brush-on resin called XTC-3D from SmoothOn, the second is a glazing putty from Bondo, and the last being a filler primer that comes in spray paint cans. Oh yeah, sand paper, a lot of sand paper. Check out my process in this episode of Bits.
