Offset 3D printing
Abstract:
This document describes techniques and apparatuses for offset three-dimensional (3D) printing. These techniques are capable of creating smoother surfaces and more-accurate structures than many current techniques. In some cases, the techniques provide a first stage of filaments separated by offsets and, at a second stage, provide filaments over these offsets. In so doing, filaments of the second stage partially fill-in these offsets, which can remove steps, increase accuracy, or reduce undesired production artifacts.
