Filament extruder 3Devo

The filament extruder produces filaments for the use in FFF processes with a defined diameter. The raw materials (mostly granules) are filled in the extrusion unit with a cone. The extrusion unit plastifies the materials and the melt is extruded threw a nozzle. The diameter of the filament is regulated with an optical take-off unit.

Materials:

Polymers with a melting temperature up to 400 °C

EINSCAN Pro + 3D-Scanner

The EINSCAN Pro + is a system which indicates and digitalisize device geometries efficiently. The scanning of the geometry is done with a SicWhite-Light Scanner. Advantage of the technology is, that there is no separately marking of the devices necessary (extra glossy devices need a coating with removable chalk spray). The mobile system with a rotary plate allows a fixed or unfixed usage of the scanner. For colored scans an extra system is available.

Scanning size:

300 x 170 mm

Handheld-Mode (marking of the devices necessary):

infinite size (depending on the data size)

Scan distance:

400 - 600 mm

Scan accuracy:

0,05 to 0,3 mm (depending on the scan mode)

Data format:

OBJ, STL, ASC, PLY

A high-precision scan of the geometries is possible with the GOM technique which is also available at Neue Materialien Bayreuth GmbH.
