THREE-DIMENSIONAL PRINTING TECHNIQUES

摘要

A process for making a component by depositing a first layer of a powder material from a dispensing head in a confined region with a cylinder (112). Spreading the material using a counter-rotating vibrating roller (114) and then depositing a binder material to selected regions of the powder material to produce a layer of bonded powder material at selected regions. Such steps are repeated a number of times to produce successive layers of bonded powder material so as to form the desired component.
