    摘要: A method of post manufacture processing of 3D printed parts involves a step of forming at least one treatment aperture through an exterior shell of a 3D printed part to provide access to a lattice of multiple layers of extruded thermo-plastic filaments within a hollow cavity of the part. The method involves a step of inserting a stabilizing substance that flows before it is set and then hardens when set through the at least one treatment aperture into the hollow cavity of the part. The method involves a step of coating the lattice with the stabilizing substance to fill spaces between the multiple layers and between individual thermo-plastic filaments, such that, when set, the stabilizing substance fixes the multiple layers of extruded thermo-plastic filaments of the lattice in position. The method reinforces and stabilizes the internal lattice structure of the part, without significantly adding material or increasing manufacturing cost.
