Precise and complex components can be fabricated with our stereolithography procedure. With specific, in-layers-hardening of liquid polymer caused by UV-laser light the real model achieves a high dimensional and contouring accuracy with a general deviation of about +/- 0,2%. For small components with a size of less than 100 mm, there is a general deviation of +/- 0.2mm. Additionally, there is the possibility to optimally improve the surfaces of stereolithography parts by manual correction.

Stereolithography is most suited for verification of design, construction, assemblies and simple functions with lot sizes of up to 5 pieces. The processing time is 2 to 4 work days.

Material data

  We use different photopolymers with different properties for our SLA models depending on the requirements and
  the field of application.

  WaterShed® XC 11122
  WaterShed® XC 11122 is suitable for producing rigid, hard, waterproof components
  similar to ABS. One crucial property is that components made from WaterShed®
  XC 11122 are almost as clear and see-through as glass, and therefore simulate
  transparent plastics.

  Accura® ClearVue
  The plastic parts made from it are extremely durable and resilient. The material's
  particular clarity and transparency make it particularly suitable for use in headlights.

  Accura® 25
  Accura® 25 is a precise and flexible material that can be used to simulate both the
  properties and appearance of polypropylenes.

  Accura® Xtreme
  Accura® Xtreme has the appearance and surface finish of a durable cast ABS
  plastic. This robust and versatile material is above all intended for functional
  components that have to withstand particularly strong forces.

  Somos® EvoLVe 128
  Somos® EvoLVe 128 is suitable for producing extremely robust, rigid,
  high-precision, waterproof components similar to ABS or polypropylene. The
  material is virtually indistinguishable from traditional thermoplastics, and is
  particularly suitable for functioning components, socket/snap connectors and

Current construction jobs

Robot Kevin the laboratory assistant

Kevin is a laboratory assistant for the performance of simple tasks, and for loading laboratory equipment. Amongst other things, the laboratory robot will transport a plate with several reagents from one device to the next. Kevin was developed by the Fraunhofer Institute – for continuous operation on weekends, public holidays and at night as well. Complete production and assembly of all cladding components for the first prototype was handled by cirp. The housing consists of SLA components that have been ground, painted and assembled. The bumpers at the bottom are made of a soft material by means of vacuum casting.
