Additive\/generative manufacturing processes have experienced a real boom in public discussion in recent years. These are manufacturing processes that create components by partially adding material layer by layer.<\/p>\n

Due to the manufacturing process, additive manufacturing offers several advantages, but also disadvantages, compared to "traditional" manufacturing methods (such as milling, injection molding, etc.). Two of the most important advantages are the design freedom and the reduced setup effort. Due to the very short setup times, parts can usually be produced very quickly and at very short notice using these processes. Small parts can be manufactured within a few hours and are available almost "immediately." Thanks to continuous development, there are now a wide variety of processes and usable materials, such as plastics, metals, plaster, paper, etc.
\nColloquially, these processes are referred to as 3D printing. However, this can lead to misunderstandings, as the 3D printing (3DP) process is only one of several processes within the technology area of "additive manufacturing." According to their use, the generative processes are classified under the areas Rapid prototyping\u00a0<\/strong> for the rapid production of prototypes, Rapid Tooling\u00a0<\/strong> for the rapid production of tools and Rapid Manufacturing<\/strong> for (series) production. Since the boundaries between these areas are fluid, the term Rapid Technology<\/strong> used. Production requires a three-dimensional model, which must be prepared according to the manufacturing process. We are particularly interested in processes that can be used to produce plastic prototypes.<\/p>\n

The processes and materials are constantly being developed, with production machine manufacturers constantly coming up with new process names. The following is a brief overview of the processes currently relevant to us.<\/div>\n
