EXTRUSION-BASED LAYERED DEPOSITION SYSTEMS USING SELECTIVE RADIATION EXPOSURE

摘要

A system for building a three-dimensional object based on build data representing the three-dimensional object, the system comprising an extrusion head configured to deposit a radiation-curable material in consecutive layers, where the radiation-curable material of each of the consecutive layers is in a self-supporting state, and a radiation source configured to selectively expose a portion of at least one of the consecutive layers to radiation in accordance with the build data.
