• low costs

• a large selection of materials

• complex shapes


from 5 pieces to 1-3 thousand pieces


How it works?

The production process starts from creation of the master-model, most often using the 3D printing method (SLA, SLS). After removing the supports and marks that appear from the printing process, we apply the appropriate surface structure. The model is then filled with silicone, then after hardening the model is removed from the silicone mold to which later resin will be poured perfectly reproducing the shape and surface structure of the previously made master-model.



For vacuum casting, we use two-component materials, most often polyurethanes. They can be hard or rubber-like with various strength parameters. In the production of prototypes, material is selected so that the parameters are as close as possible to the material that will be used in mass production. The color is obtained by adding the appropriate pigments.


Master-Model and surface structure

Vacuum Casting is a replication method. That is why the master-model is needed to make the first mold, whose shape and surface structure perfectly reflects the silicone mold. Master-model is most often created using 3D printing technologies (SLS, SLA), CNC. Imperfections remaining after printing or milling are removed manually and then the surface structure is applied. A suitable surface is obtained by polishing or dusting paints with different structures, in case of homogeneous surfaces - structural foils can be used.

Additive manufacturing
  • ​Large format and precise 3D printing

  • high quality post-processing & finishing of 3D prints

  • Matching printing technology and materials to customer needs


1. SLA (Stereolitography)

  • material: resin / polymers

  • maximum dimensions: 1500 x 750 x 750 mm

  • advantages: precise printing, smooth surface, easy to process

  • disadvantages: fragile material, low temperature resistance


2. SLS (Selective Laser Sintering)

  • material: powder / polymers

  • maximum dimensions: 550 x 550 x 750 mm

  • advantages: precise printing, high temperature resistance, good mechanical properties, relatively low costs

  • disadvantages: the material absorbs moisture and dirt, it is necessary to cover with paint, a porous surface


3. SLM (Selective Laser Melting)

  • material: powder / metal; aluminum, stainless steel, ...

  • maximum dimensions: 800 x 400 x 500 mm

  • advantages: precise printing, complex shapes, rapid prototyping

  • disadvantages: price, time-consuming post-processing
