Smooth surfaces and detailed, intricate structural representations with minimal deviation from the 3D model have made stereolithography a popular method for the additive production of technical prototypes or design studies for years. Especially in innovation-driven industries such as medicine, mechanical engineering or automotive engineering, rapid prototyping with the SLA process has proven its worth, since it is possible to produce informative physical models in no time for assessing function and geometry. If potential for improvement becomes apparent in the test phase, changes and further developments can be transferred directly to the 3D model and implemented thanks to the CAD-based work process. Due to the excellent surface properties of the 3D object, post-processing is usually not necessary.
