Offset 3D Printing

摘要

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.

主权项

1. A method comprising:
providing a first stage of first parallel filaments, the first stage having a first contour, the first parallel filaments having offsets separating the first parallel filaments; and providing, over the first stage of first parallel filaments, a second stage of second parallel filaments, the second stage having a second contour, the second parallel filaments provided over the offsets effective to place the second parallel filaments between the first contour of the first stage and the second contour of the second stage.
