Abstract
Official abstract text for this publication.
An apparatus and a process for removing a support structure from a 3D printed part, where the 3D printed part along with the support structure is placed in an acid solution and the part is surrounded by an induction heater. The acid solution is recirculated through the acid tank to prevent the acid solution from heating up too much. Small surfaces of the part are heated up by the induction heater before larger pieces are heated so that the acid will remove the smaller pieces first. After enough time, all of the support structure is removed by the acid and the heater to leave the finished 3D printed part with the support structure removed.
First claim
Opening claim text (preview).
I claim the following: 1. A process for removing a support structure from a 3D part formed using an additive manufacturing process comprising the steps of: forming the 3D part using an additive manufacturing process in which a support structure is also formed; placing the 3D part with the support structure in an acid solution; heating the 3D part with the support structure within the acid solution using an induction coil submerged within the acid solution such that the support structure is removed by the acid solution; and, recirculating the acid solution while the 3d part is being heated to limit a temperature rise of the acid solution.
