摘要： Described is a 3D printer, which is configured to build up at least one three-dimensional component in layers in a construction space by forming construction material layers lying one upon the other, of particulate construction material, and selectively solidifying several adjoining construction material layers in a respective partial region thereof. The 3D printer comprises a coating device 3 which is movable in a first direction H1 across the construction space B1 to supply construction material to the construction space B1 in the form of a uniform construction material layer of the construction material to be solidified, a printing device 5 which is movable in a second direction H2 across the construction space B1, in order to output in a controlled manner a flowable treatment agent to a partial region of a previously applied construction material layer, which treatment agent contributes to a selective solidification thereof, and a control device C, which is configured to control the coating device 3 and the printing device 5 in such a way that they travel across the construction space B1 in a way to overlap in time and/or that they, in an overlapping manner, supply construction material to the construction space B1 and dispense flowable treatment agent in a controlled manner to a partial region of a previously applied construction material layer, respectively.

摘要： A post-treatment process for increasing the hot strength of a formed part (100) made of particulate material and binder is disclosed, wherein the formed part (100) is formed a part manufactured by 3D printing (S72) and after its manufacture is heated (S30) using a heating device (40), and the heated formed part (100) is exposed (S50) to an atmosphere enriched with gaseous water generated by supplying water.
