The LightFab 3D Printer is specially designed for our subtractive 3D printing process SLE (selective laser-induced etching) and is also used for other 3D laser writing processes inside transparent materials like wave guide writing, 2-photon-polymerization, backside ablationand crack-free markings. We integrate our system technology into your production line and offer special machines enabling even mass-production of 3D parts. In addition, we support you in process development for special structures, new materials as well as higher throughput.
LightFab - 3D Printer
Our LightFab 3D laser Printer consists of a high dynamic 3D Microscanner, a high precision 3-axis system for stepping, fs-laser, camera andvision system for automatic alignment, laser safety and an innovative CAD/CAM/nc software package in one housing: LightFab 3D Printer. The LightFab 3D Printer is specially designed for oursubtractive 3D printing process SLE (selective laser-induced etching) and is also used for other 3D laser writing processes inside transparent materials like waveguide writing, 2-photon-polymerization, backside ablation andcrack-free markings. We integrate our system technology into your production line and offer special machines enabling even mass-production of 3D parts. Inaddition we support you in process development for special structures, new materials as well as higher throughput.
Fraunhofer Institute for Laser Technology ILT and Fraunhofer Institute for Silicate Research ISC together with Lightfab from Aachen are developingan entirely new process chain for the manufacturing of three-dimensional devices. It is perfect for Direct Laser Writing processes such as multi photonpolymerization of 3D polymer micro structures, 3D waveguide writing by ultra fast laser inscription, 3D lithography in glasses and crystals by selective laser-induced etching, internal welding of glass, and micro structuring by precision ablation with e.g. 1 um focus diameter.
The LightFab 3D laser Printer is designed for fastest automatic 3D printing with the included CAD/CAM software. Advantages of SLE are the large precision (~1um), no debris, true 3D capability and the high processing speed using our LightFab 3D Printer. In cooperation with Fraunhofer ISC, the two-photon polymerization technology is combined with SLE technology to realize the processing of complex structures such as curved surfaces and curved channels.
LightFab3D laser printer can be used for applications such as micro fluidics, micro mechanics, integrated optics and other applications that require high precision, high resolution 3D microstructures. E.g. cell sorter, microfluidical cross-section chip, rotatable gear, M1 threaded hole in quartz glass, microchannel, 3D nozzles in quarts glass and so on.

Laser labelling with the SIM marking system from GMBH
Ourlaser labelling system provides self-contained and high-performance solutionsfor laser labelling small batches of individual parts. The"STANDARD", “BASIC” and “ADVANCED” laser marking system versions canbe set up directly on a desk or mounted onto the moveable base frame. By usingthe most up-to-date 3-axis laser marking systems, we are able to offer you a laser labelling system that can be precisely adjusted to the materials and partgeometry you wish to label.
The integrated optical “3-axis technology” in the SIM laser marking systems, which allows the focal point to be freely set, is especially impressive. This allows the marking laser to follow various shapes, easily switch between different heights (± 21 mm = 42 mm) and sharply mark any shape, including slanted surfaces, cylinders and cones.
Depending on the type of laser, the size of the labelling field varies between 120 x 120 mm to 330 x 330 mm.
Various laser marking systems for different types ofmaterials, including systems with power ratings of between 13 and 50 W:
CO2 laser with a wavelength of 10,600 nm
YVO4 laser with a wavelength of 1,064 nm
Fibre laser with a wavelength of 1,090 nm
Application：Mental, plastic, ceramic、Paper、PCB、Wafer
