Publication number: 20220332039Abstract: A process for producing a three-dimensional (3D) object by a fused filament fabrication process employing at least one filament and a three-dimensional (3D) extrusion printer. Within said process, the filament is first fed to a cooling device, where the filament is cooled down to a temperature of 20° C. or colder. Afterwards, the cooled-down filament is transported to a heating device located inside the printing head of the 3D extrusion printer, where the cooled-down filament is heated to a temperature, which is high enough to at least partially melt the filament. The heated filament is extruded through the nozzle of the printing head of the 3D extrusion printer in order to obtain an extruded strand, which in turn is used to form the respective 3D object in a layer by layer way. Further an apparatus is disclosed, to be used within such a fused filament fabrication process or 3D printing technology, respectively.Type: ApplicationFiled: August 14, 2020Publication date: October 20, 2022Inventors: Rene ARBTER, Rudolf SEILER, Thorsten Martin STAUDT
