This document provides information about 3D printing, lasercutting, and rapid prototyping technologies. It discusses why rapid prototyping is useful for creating physical models from virtual designs and inspecting technical specifications. It then describes various 3D printing and lasercutting techniques like stereolithography, fused deposition modeling, selective laser sintering, and polyjet processes. Examples of properties and suitable applications for each technique are given. The document concludes by discussing how to get started with a lasercutting design project and provides an example of designing a cardboard lamp.
