Keywords: Micro precision manufacturing, Polymer components

Purpose: check the dimensional tolerances of the parts produced by additive manufacturing with microscope e polymerization

Design methodology/approach: investigation of dimensional and surface tolerance carried out using a focus variation microscope evaluating the contrast of the images with vat polymerization method.

Findings: experimentation is allowed to highlight the repeatability of the machine to create quite precise geometries. There are two cases, the cylindrical surfaces are more precise, the box ones are less precise

Limitations: to obtain small tolerances further processing is required

Practical implications: the additive manufacturing technique allows to crate precise surfaces in the order of ten microns

Originality/value: particular measurement technique for additive manufacturing
