Rapid Prototyping

Rapid Prototyping at the Ottobrunn Production Centre, Munich.

 

 Rapid Prototyping

Rapid prototyping is used for the production of demonstration and functional models using Stereo Lithography and Selective Laser Sintering techniques. Models range from original size down to sub-scale.

Both techniques are based on 3D-CAD models. Each component is developed step by step in layers of up to 1/10 mm.

Advantages of Rapid Prototyping technology are:

  • Cost reduction up to 50%.
  • Processing time reduction up to 75%.
  • High design flexibility to enable short term component modifications.
  • Cost effective component production for demonstration purposes and functional test samples.

The Process

Stereolithography:
Components are generated using liquid UV-sensitive polymers that are cured layer by layer with laser beams.

Selective Layer Sintering:
Component are generated by fusing a powder layer by layer with laser beams.

Manufacturing Process:

  1. Generation of a 3D-CAD model, such as CATIA.
  2. Transmission of CAD data to a laser sintering machine.
  3. Production of a polystyrene blank using the rapid prototyping process.
  4. Production of a ceramic mould from the polystyrene blank.
  5. Removal of polystyrene from the ceramic mould.
  6. Pouring of alloy into ceramic mould.
  7. Removal of ceramic mould from alloy component.
  8. Machining of component functional surfaces.
