Abstract

<jats:title>Abstract</jats:title><jats:p>Additive Manufacturing (AM) technologies have been recently adopted to produce functional spare parts in advanced applications. High dimensional accuracy is essential in these applications, where it is expected for the dimensions of manufactured parts to meet the design specifications and tolerances. Different additive manufacturing processes exhibit different dimensional accuracies. This paper investigated the dimensional accuracy of additively manufactured metal parts produced by Fused Filament Fabrication (FFF). We designed a new testing structure (Test-Part) incorporating multiple features in a single build. Two different metal materials, 17-4 PH stainless steel, and copper were used to manufacture the test parts. We also compared the dimensional accuracy of metal parts against a composite polymeric material, Onyx, fabricated using the FFF process. The manufactured Test-Parts were scanned using an advanced laser scanning technology to precisely measure the dimensions and capture the geometry’s details. A detailed three-dimensional analysis was conducted to evaluate the extent of resemblance between the manufactured parts and the CAD model. Results showed that the copper Test-Part exhibited the highest dimensional accuracy (lowest dimensional deviation compared to the CAD model) among the three materials. Overall, metal 3D printed parts exhibited better dimensional accuracy compared to composite polymeric parts.</jats:p>
