Rapid prototyping, or more commonly called 3d printing, is a technique which relies on the addition of material, an additive process, which contrasts with the technology used in the other two assignments, the laser cutter and the milling, which are based on subtractive techniques. As a consequence, this technology has the potential to be waste free. Additive manufacturing can make use of a relatively large palette of materials in a field which is constantly evolving. For the sake of the course, we will be printing with the Projet 1500 (Photosensitive Resin). The scale of the parts produced is still a strong constrain in school and elsewhere, but teams around the world are working on braking these barriers to print objects on a human scale with better performing materials.
