Additive manufacturing for prototypes and series products with 3D printers from CMC Maschinenbau

Hardly anyone can imagine that the combustion chambers of SpaceX's rocket engines were created in a 3D printer. Even entire single-family homes are printed with 3D printers today. However, these rather exotic applications impressively demonstrate the possibilities of 3D technology.

3D printers offer some significant advantages over other manufacturing techniques. One of the most essential is the fact that you don't have to worry about how and if manufacturing is possible during the design process. But there are other, important advantages over traditional manufacturing techniques:

  • Tool-less production e.g. for rapid prototyping, sampling and concept studies

  • No additional molds, fixtures or production equipment required

  • Demand-driven production possible from batch size 1 (on-demand production)

  • Wide range of different products (ABS, PP, PEAK, PETG, PEEK, PVA, PEI, PPSU, etc.) to adapt material properties to functional requirements

  • Often significant weight advantage over aluminum and injection molded parts while maintaining high strength and stiffness (optimized by carbon fiber filaments)

  • Extremely high design freedom with the possibility of rapid, customer-specific adaptation 

  • Virtual design in CAD system with high design freedom without limitations of classical manufacturing processes

  • Possibility to produce parts that are difficult or impossible to produce using classical manufacturing methods

  • minimal waste, low energy costs, sustainable production

  • Time- and cost-efficient work for prototyping and smaller series, modifications available very quickly

  • Different component variants for functional tests can be produced without high tooling costs

  • Clustering of several components in one printing process enables high production efficiency and cost savings

  • Production of 10 identical components costs the same as production of 10 different components - advantage over injection molding: no additional tooling costs for variants

  • use of standard file formats that are recognized throughout the industry

  • robust, compact design, only one power connection is required
