A. Hopf can also produce prototypes using 3D printing. Within the development department of the mould shop, we also create visual demonstrative CAD models, which form the basis for further development processes. Existing customer CAD data can also be converted into a 3D model in ABS. This helps the marketing and sales departments to assess the functionality and design of a product during the development and production stages, before the mould is built. In many cases, this avoids the need for more costly pilot tooling.
