Stereolithography vs. PolyJet: Photopolymer 3D Printing Materials and Applications

摘要

Stereolithography and PolyJet are often grouped together beneath the photopolymer branch of additive manufacturing. While it is true both 3D print technologies share a similar printing foundation - they both use UV energy to cure liquid photopolymer - PolyJet and Stereolithography involve dissimilar print methods to achieve a fully cured end product. These build style variances mean PolyJet and Stereolithography are not always suited for the same types of applications. Understanding their differences will guide you toward using each process for the right application rather than force fitting one photopolymer process to meet every project. The main differences between PolyJet and Stereolithography are part resolution, manufacturing speed, part size, materials and applications.
