Geometrical shape assessment of additively manufactured features by Continuous Liquid Interface Production, vat photopolymerization method

Additive Manufacturing (AM) is a notable procedure for direct production of miniaturized polymer components, mainly due to the ability of the process to produce complex geometries with time and cost effective iteration cycles in the development of new plastic products. This study evaluate the capability of the vat photopolymerization in terms of geometry, when printing features of different sizes and shape.

Continuous Liquid Interface Production (CLIP) technology was used for printing the features which is a new method to produce monolithic polymer parts at high speed. For this purpose, two test artifact specimens designed with micro features of different geometries and printed in different batches and evaluated the variability of the results in a single and in various prints.
