Importance of Ductility in Photopolymer Resin 3D Printing, Stereolithography, Vat Photopolymerization, and Polymer Additive Manufacturing
Ductility is a key mechanical property that refers to a material’s ability to undergo significant plastic deformation before rupture. It is a measure of a material’s ability to withstand tensile stress, which is particularly important in applications where flexibility and the ability to absorb energy without breaking are required. In the context of photopolymer resin 3D printing, stereolithography, vat photopolymerization, and polymer additive manufacturing, ductility is crucial for ensuring the durability and functionality of printed parts, especially when they are subjected to mechanical loads.
