Three Dimensional Printing Method

摘要

A method of forming, in a single three dimensional printing operation, one or more parts which are to be in mutual abutment and to be relatively movable relative to one another in a final assembly. The method includes printing, simultaneously with the desired one or more relatively movable parts, additional components which support the closely abutting, mutually movable parts apart from one another during the three dimensional printing operation. The additional components may then be removed from the newly printed assembly so that the mutually movable parts can be joined in a desired closely abutting assembly wherein the mutually movable parts can move as intended. The additional support components may hold the mutually movable parts in close proximity to their final positions in the final assembly such that each of the mutually movable parts is moved into the final assembly in a straight motion parallel to every other straight motion.

1. A method of forming an assembly by three dimensional printing, the method comprising:
forming by three dimensional printing a first object including one or more first engagement features; forming by three dimensional printing one or more second objects each of which includes a second engagement feature which complements one of the first engagement features of the first object such that interfit of the first object to the second objects is enabled; and forming by three dimensional printing a support structure which is configured to engage the first object and to simultaneously support the second object such that the second engagement feature of the second object is supported in close proximity to the first engagement feature of the first object.
