Abstract

Volumetric additive manufacturing (VAM) is an optical 3D printing technique in which patterned light is projected into a photoactive resin from multiple angles. The patterned light is chosen to solidify the resin in a specified 3D shape. A typical VAM printer consists of 3 main components – a projection system, a rotation mechanism, and a cylindrical vial of resin mechanically fixed to the rotation mechanism. Typically, the alignment of the projection system and rotation mechanism are completed prior to any printing while the alignment of the vial is done print by print. The vial alignment is often tedious, time consuming, and is error prone, thus decreasing the throughput of the printer. Additionally, alignment errors cause decreased print volume and resolution. In this work, we show a novel technique to detect the relative alignments of these 3 systems and then electronically correct for the misalignments which maximizes print volume and resolution.
