Hello, 

When working with SLA technology or other 3D printing processes, material selection is critically important for the success of the project. For example, for prototypes requiring high detail and where aesthetic appearance is important, high resolution and low viscosity resins are preferred. For medical devices requiring durability and flexibility, resins offering high impact resistance and long-term mechanical performance are ideal. Biocompatibility is another important factor in medical applications; therefore, for parts in direct contact with the skin or to be used inside the body, FDA approved biocompatible resins or ABS-like and PP-like materials specific to your medical needs may be preferred. 

Based on my many years of experience, each project is unique and the material selection should be made according to the specific needs of the project. For instance, many medical devices are cleaned with alcohol so materials that will not dissolve with alcohol derivatives should be chosen. Thoroughly analyzing the purpose of use of the prototype and the conditions it will be exposed to is critically important in selecting the most suitable material.
