Otoflash G171: Flash-curing device for light-curing with N2 Hook Up

The Otoflash G171 is used for curing of light-curable resins through light-induced photopolymerization. It is optimized for quick curing of medical grade 3D printed materials using Nitrogen. Featuring two bottom mounted flash lamps operating at 10 flashes per second, it is ideal for curing otoplasties, hearing aids and dental appliances.

The Otoflash G 171 has two flashbulbs that emit light into the polymerisation chamber from below. It is therefore especially suitable for application in otoplastics/hearing aids/dental applicances and in the production of jewellery. The device can be used for the photopolymerisation of all light-curable materials where the curing takes place at a wavelength of 280-580 nm.

Similarly, work pieces produced by means of new technologies such as 3D printing / rapid manufacturing can be post-cured. The Otoflash G171 enables the production and processing of light curing materials of different consistencies and pigmentation, as well as repairs with corresponding materials and lacquering.


With its technical configuration, the Otoflash G171 enables short curing times: In the operating mode, two flash bulbs fitted at the bottom produce ten flashes per second. The respective light radiation at a wavelength of 280-580 nm is very intense. Compared to other methods this achieves a substantially better curing of the materials, resulting in very good physical characteristics and reduced residual monomer content (inhibition layer).

The Otoflash G171 is also deliverable with a protective gas appliance (N2). This prevents any oxygen inhibition, surfaces are cured completely non-stick and there is no need to remove or wipe away the inhibition layer.

The Otoflash G171 has an integrated elapsed time meter, is simple to use and is extremely easy to maintain.
