Prusa I3 modified

Characterisitc:
Modifiable system for the development of new processes   
Printing technology:
FFF
Build volume:
200 x 200 x 200 mm
Melt temperature:
up to 400 °C

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.

Filament diameter:
1,75 mm or 2,85 mm (±0,05 mm)
Materials:
Polymers with a melting temperature up to 400 °C
Minimum amount of material:
50 – 100 g
Metals: LMD - Laser Melting Deposition Machine (self-development)

 

This process enables the production of large and complex lightweight structures from high-strength alloys using high vacuum ≤ 5 x 10-5 mbar.

The machine was developed within the cooperation project "Process and plant prototype for additive series production of large and complex lightweight structures from high-strength alloys (AdLes)" together with the project partners Evobeam GmbH (evobeam) IRCAM GmbH (IRCAM), Universität Bremen, Airbus Stiftungsprofessur für Integrative Simulation und Engineering von Materialien und Prozessen.

The ZIM-Koop project ZF 4176702LP6 was funded by AiF Projekt GmbH within the Central Innovation Program for Small and Medium-Sized Enterprises (ZIM) of the Federal Ministry of Economics and Technology on the basis of a resolution of the German Bundestag.

3D-Scanning

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.
