Together with our partners, CIREX can also produce prototypes by means of machining. These prototypes are produced by turning and/or milling steel until the desired product is created. This can be done using both conventional and CNC machines. A disadvantage of mechanical operations is that these limit the geometries that can be produced. Properties of the material used can also cause limitations, such as hardness, for example. This method of producing prototypes is mainly used for complex parts where ‘Form, Fit and Function’ must be tested before creating a mold. As CIREX collaborates with various partners to produce machined prototypes, we can guarantee short delivery times, even for large batches.


  • High surface roughness
  • High dimensional accuracy
  • 3D models can be larger than is possible with wax printing
  • Relatively expensive compared to printed prototyping models
  • Suitable for parts with complex design: testing ‘Form, Fit and Function’
  • Longer process due to collaboration with partners
