This study presents the additive manufacture of objects using mass-functionalized photo-resins, which are additively photopolymerized using the laser stereolithography technique. The mass functionalization is based on the incorporation of copper nanowires used as fillers at different concentrations. Cylindrical and tensile test probes are designed and manufactured in a layer-by-layer approach using a low-cost laser stereolithography system working with a layer thickness of <inline-formula> <math display="inline"> <semantics> <mrow> <mn>100</mn> <mo>&nbsp;</mo> <mrow> <mi mathvariant="sans-serif">&#181;</mi> <mi mathvariant="normal">m</mi> </mrow> </mrow> </semantics> </math> </inline-formula>. The morphological, mechanical, thermal and chemical results help to show the viability and potential that this combination of mass-functionalized resins and technological processes may have in the near future, once key challenges are solved. Finally, some potential applications are also discussed.
