Method and device for 3d printing using temperature-controlled processing

Abstract

The invention relates to a method for producing 3D components, particulate material being applied in layers to a building platform in a closed build space and printing fluid being selectively applied, and these steps being repeated until a three-dimensional component is obtained, the relative humidity or the relative solvent concentration in the atmosphere in the build space being set to a selected value, and/or the temperature in the build space being set to a selected temperature.

What is claimed is: 
     
         1 - 8 . (canceled) 
     
     
         9 . A device, suitable for 3D printing methods, comprising
 a. a closed build space;   b. a coater for applying a layer of particulate material to a building platform in the closed build space;   c. a printer for selectively applying a printing fluid to the layer of particulate material;   d. a sensor for measuring a temperature of an air in the closed build space;   e. an air conditioner for regulating a temperature and a humidity of the air in the closed build space and for flowing a processed air into the closed build space, wherein the temperature is regulated to −18° C. to 40° C.; and   f. a diffusor or a baffle plate for controlling or eliminating eliminating air currents from the processed air in the closed build space.   
     
     
         10 . The device according to  claim 9 , wherein the build space is essentially tightly sealable. 
     
     
         11 - 17 . (canceled) 
     
     
         18 . The device of  claim 10 , wherein
 the device includes a water-based humidifier for regulating the humidity of the air in the closed build space.   
     
     
         19 - 20 . (canceled) 
     
     
         21 . The device of  claim 10 , wherein the closed build space is insulated. 
     
     
         22 . The device of  claim 10 , wherein the device includes an IR emitting unit. 
     
     
         23 . The device of  claim 10 , wherein a reservoir of the coater includes a water-insoluble particulate material. 
     
     
         24 . The device of  claim 10 , wherein the device includes a removable build container. 
     
     
         25 . The device of  claim 10 , wherein the device includes a 3D part having particulate material joined by bridges of a dried water glass binder, wherein the 3D part is embedded in loose particulate material. 
     
     
         26 . The device of  claim 23 , wherein the reservoir of the coater further includes a dried water glass binder. 
     
     
         27 . The device of  claim 26 , wherein the printer includes the printing fluid, wherein the printing fluid includes or consists of water. 
     
     
         28 . The device of  claim 27 , wherein the device includes a humidity sensor.
