Device for fast parallelized additive manufacturing

In additive manufacturing, e.g. in Fused Filament Fabrication (FFF), the build-up of the manufactured object is often slow, because each layer has to be completed before the next can be started. Since additive manufacturing is now no longer used for mainly prototyping, but also for serial productions, saving time during the manufacturing process is crucial in order to reduce production costs. Individual printing units are limited in their potential to speed up.

The invention describes a Fused Filament Fabrication (FFF) manufacturing device for the layered production of objects. Its main feature is the multiple number of printing units (extruders), each with a separate transfer plate. The printing unit extrudes at least one layer onto a transfer plate, which then moves into position. The build plate, which is rotated 180 degrees relative to the transfer plate, then moves into position over the transfer plate. Afterwards the build plate takes over the layer from the transfer plate by means of controlled pressure and temperature in order to produce the object.
