Abstract (en)
[origin: WO2018215113A1] The invention provides an after-treatment process for increasing the hot strength of a shaped part (100) produced from particulate material and binder in which the shaped part (100) is a shaped part produced by 3D printing (S72) and, after its production, is heated by using a heating device (40) (S30) and the heated shaped part (100) is exposed to an atmosphere created by feeding in water and enriched with gaseous water (S50).
