freeformer system

Using tiny droplets to create fully functional parts

The industrial additive manufacture of functional parts is highly demanding: It involves a wide range of original materials, material and colour combinations, as well as high part quality and strength. Individual settings options are required during the manufacturing process.

That's why we developed the APF (ARBURG Plastic Freeforming) process and the freeformer specifically as an open system. Tiny plastic droplets provide the basis for flexible adjustment options. The droplet size and process control can be influenced in a targeted manner. This gives you the freedom to individually optimise the properties of your additively manufactured parts and to process your own materials

  • Customised: different sizes with two or three discharge units
  • Unique: using qualified standard granulates to produce fully functional parts – as a complex, resilient hard/soft combination
  • High-quality: pulsed nozzle closure with piezo technology ensures high quality parts
  • Extensive: growing material database with process settings for various amorphous and semi-crystalline thermoplastics
  • Open: free programming of process – from geometrical slicing to the discharge and positioning of the droplets
  • Adaptable: modified original materials can be used quickly and easily, for example for the aerospace industry or in medical technology

This is how it works

ARBURG Plastic Freeforming (APF)
In the APF process, qualified standard granulates are melted using the same method as in injection moulding and are discharged as tiny plastic droplets. The more densely the droplets are positioned in relation to one another, i.e., the more tightly the parts are "packed", the higher the mechanical properties.
