Multi-jet modeling (MJM)

Multi-jet modeling is a rapid prototyping method in which a plastic model is created in layers directly from the 3-D CAD data using a print head with several linear nozzles. The wax-like thermoplastics are sprayed on as fine drops through a heated print head at a resolution of 300 dpi and higher and polymerized by means of UV light. For overhangs, a support structure of lower-melting wax is constructed that is removed later by being heated. The finished models can be very easily machine-processed, glued or coated (for example by means of vacuum metallization).

The method which is very similar to that of an inkjet printer is particularly suitable for high-detail, filigreed concept models and design prototypes. From this true-to-detail original model, castings (using a vacuum casting process, for example) can be produced in subsequent processes if needed.

G.W.P. AG manufactures high-quality plastic prototypes using the MJM process. Whether components for concept development, samples for design review or function prototypes for form and fit analysis, multi-jet modeling is the best rapid prototyping method when speed and maximum detail are needed.

Advantages of multi-jet modeling:

  • Thermoplastic prototypes with a good dimensional stability that can be machine processed
  • Restricted mechanical load (few materials)
  • Construction area: 298 x 185 x 203 mm
  • No geometrical restrictions
  • Very fine details with a high resolution (layer thickness of approx. 0.1 mm)
  • Excellent surface quality
  • Very short production times
  • Greater complexity does not increase the cost


Take advantage of G.W.P.'s experience in the production of high-quality plastic prototypes – You will save costs and time!
