Additive manufacturing in large scale
Neue Materialien Fürth GmbH
There is a vide variety of additive manufacturing technologies on the market. However, the majority of these are limited to a maximum printing volume of a few hundred millimeters. In case of request for larger parts, there are only a few suitable 3D printing processes. Problematic issues are often the long production time, the high material requirements or the specific material properties, which do not allow an upscaling of the respective processes. Gel-dispensing-printing (abbreviation: GDP) is an interesting alternative .
In the GDP process, a highly viscous, UV-curing gel is dispensed in layers through a nozzle and then cured directly by UV radiation. The special viscosity properties of this reactive resin enable layer thicknesses of 0.75 to 1.3 mm. With high printing speeds three-dimensional objects can be produced in relatively short production times. The size of the produced parts is only limited by the size of the machine.
