The present invention relates to a method of producing an article, comprising the step of producing the article by means of an additive manufacturing method from a build material comprising an aromatic polycarbonate and interference pigments and/or pearlescent pigments from the group of the metal oxide-coated micas. The invention likewise relates to an article obtainable by the method. The build material further comprises ≥0.05% by weight to ≤3% by weight of anhydride-modified α-olefin polymer.

Additive manufacturing process using a building material that contains metal-oxide coated mica

A deformable body, wherein the body is constructed from a multiplicity of layers of a polymer construction material and in which a construction direction is defined perpendicular to the layers. The body preferably comprises layers with a multiplicity of curve pairs () which are formed by the construction material and which run in the same direction as one another, the curve pairs comprise in each case two periodic curves () running oppositely with respect to one another, and the curve pairs comprise portions of maximum spacing to one another () and portions of minimum spacing to one another (). In one part of the layers, in adjacent curve pairs (), at least one portion of maximum spacing () of one curve is connected to a portion of maximum spacing () of an adjacent curve, in a further part of the layers, in adjacent curve pairs (), at least one portion of maximum spacing () of one curve is not connected to a portion of maximum spacing () of an adjacent curve, in a further part of the layers, in adjacent curve pairs (), at least a part of the portions of minimum spacing () are connected to one another, and in a further part of the layers, in adjacent curve pairs (), at least a part of the portions of minimum spacing () are not connected to one another. The invention also relates to a method for producing the body and to a device for supporting and/or bearing a person having the body according to the invention. The boy may be used inter alia as a mattress or as a vehicle seat.

Deformable body and method for the production thereof

The invention relates to a method for producing a three-dimensional object by means of a powder-based additive production method from at least one first powdery material, wherein the at least one first powdery material comprises at least one first compound having a first reactive group a). The first reactive group a) is selected from the group consisting of an isocyanate group, a blocked isocyanate group, or a mixture thereof. The invention further relates to a component produced using the method according to the invention, and to powdery material that is suited for the method according to the invention.

Method for producing products by means of additive manufacturing methods using reactive powders, and products thereof

The invention relates to a method for producing an object, comprising the step of producing the object from a construction material by means of an additive manufacturing process, wherein the construction material comprises a plurality of thermoplastic polyurethane materials. The materials differ by at least one mechanical property such as the shore hardness or the elongation at break. The invention also relates to an object obtained according to said method.
