Cover Story: Additive manufacturing (AM) is a technique for constructing physical models, prototypes, and production parts. Stereolithography (SLA), a process within AM, utilizes liquid photopolymer to chemically fabricate parts using a UV laser to selectively cure and solidify resin in a layer-by-layer process. Injection molding (IM), preferred for large production volumes, requires precise tooling usually machined from aluminum or steel via CNC. SLA 3D printing serves as an alternative method to produce insert tools for small- to medium-scale IM quantities, offering shorter lead times and reduced costs. This study aims to evaluate post-process techniques, focusing on removing the stair-step effect, replicating conventional surface finishes, and assessing trade-offs in dimensional accuracy and thermal and mechanical properties for IM applications.
