The present invention relates to a method of producing a shaped body, wherein, in step i), a layer of a sinter powder (SP) comprising at least one polyhydric alcohol inter alia is provided and, in step ii), the layer provided in step i) is exposed. The present invention further relates to a method of producing a sinter powder (SP) and to a sinter powder (SP) obtainable by this method. The present invention also relates to use of the sinter powder (SP) in a sintering method, and shaped bodies obtainable by the method of the invention.

Sinter powder containing a multivalent alcohol for producing moulded bodies

The present invention relates to a sinter powder (SP) comprising at least one semicrystalline terephthalate polyester (A), at least one amorphous terephthalate polyester (B) and at least one phosphinic salt (C). The present invention further relates to a method of producing a shaped body by sintering the sinter powder (SP) or by an FFF (fused filament fabrication) method, to a shaped body obtainable by the method of the invention, and to the use of a phosphinic salt in a sinter powder (SP) for broadening the sintering window (W) of the sinter powder (SP).

Sintered powder (SP) containing a partially crystalline terephthalate polyester, an amorphous terephthalate polyester and a phosphinic acid salt

The present invention relates to a process for producing a polyamide powder (PP) comprising at least one semicrystalline polyamide (P) and at least one additive (A). The semicrystalline polyamide (P) and the at least one additive (A) are initially compounded with one another in an extruder and subsequently introduced into a solvent (SV) in which the at least one semicrystalline polyamide (P) then crystallizes to obtain the polyamide powder (PP). The present invention further relates to the thus obtainable polyamide powder (PP) and to the use of the polyamide powder (PP) as sintering powder (SP) and also to a process for producing a shaped body by selective laser sintering of a polyamide powder (PP).

Process for producing a polyamide powder by precipitation

The present invention relates to a process for producing a shaped body, wherein, in step i), a layer of a sinter powder (SP) comprising at least one mineral flame retardant inter alia is provided and, in step ii), the layer provided in step i) is exposed. The present invention further relates to a process for producing a sinter powder (SP) and to a sinter powder (SP) obtainable by this process. The present invention also relates to the use of the sinter powder (SP) in a sintering process and to shaped bodies obtainable by the process of the invention.

Sinter powder containing a mineral flame retardant for producing moulded bodies

The present invention relates to a process for the production of a reinforced polyamide (rP) in an extruder. In this process, a first mixture (M1), a second mixture (M2) and a third mixture (M3) are added into the extruder, and subsequently at least one carbon material is added to obtain a carbon containing polymerizable mixture (cpM) in the extruder. This carbon containing polymerizable mixture (cpM) is polymerized and subsequently devolatilized to obtain the reinforced polyamide (rP). Furthermore, the present invention relates to the reinforced polyamide (rP) obtainable by the inventive process.
