AE12

The material system for plastic parts

The material system AE12 was developed by Additive Elements as an experienced 3D printing service provider especially for the Binder Jetting process. It is based on PMMA and gives the finished part properties that were not possible before with alternative manufacturing processes. Compared to manufacturing with SLS, significant cost savings and higher productivity can be reached.

Further details on the mechanical properties and design recommendations can be found in our technical data sheet.

possible part size

The profiles of requirements of a plastic are very different. Characteristics such as hardness, elasticity, temperature behaviour and chemical compatibility are typical application requirements. Through the combination of powder and pressure fluid as well as the design of the process, far-reaching changes of the resulting part properties can be achieved in order to realize special applications.

The process

  • PRINTING

    The model is built as usual on the 3D printer, but the powder is selectively filled with liquid. The model is left in the powder cake.

  • HARDENING

    The complete assembly of the parts is carried out in a heat chamber, where the model reaches its final strength.

  • EXTRACTION

    The model can be removed without special care.

  • BLASTING

    The model is blasted manually or automatically.

  • READY

    The model impresses with its good surface, strength and dimensional accuracy.
