COLOR SWITCHING FOR THREE-DIMENSIONAL PRINTING

---

Abstract

---

By reversing the direction of a first build material fed into an extruder, the first build material can be wholly or partially evacuated from the extruder before a second material is introduced. This approach mitigates transition artifacts and permits faster, more complete changes from one build material to another.
