Abstract
The invention relates to a device and to a method for producing 3D moulded parts, wherein a preheating container is used.
Claims19
A particle material preheating container suitable for a 3D printing device, said container comprising one or more heating means, wherein the heating means is/are arranged in the area intended to receive the particle material and wherein the heating means is/are substantially surrounded by the particle material wherein the particulate material preheating container includes a closure for dispensing preheated particulate material to a recoater.
A device suitable for a 3D printing method, said device comprising one or more particle material preheating containers comprising one or more heating means substantially surrounded by the particle material;
- wherein each of the one or more particulate material preheating containers includes a closure for dispensing preheated particulate material to a recoater.
A method for producing a molded part by means of particle material application and selective solidification and all further process steps and process means necessary for this purpose, wherein the particle material is heated to a target temperature in a preheating container prior to introduction into the recoater or/and prior to application to the build field.
