Abstract: Disclosed embodiments relate to gelling aqueous ceramic slurries with temperature using laser-assisted free-forming to provide a break-through of rapidly making ceramics from slurries and computer assisted design files. Methods according to various embodiments are superior to any other since no toxic materials are used. The slurries are made with edible and safe compounds.

Abstract: Method for additive manufacturing of a metallic component includes providing a metallic powder; providing and/or producing a metallic support structure on a build platform, wherein the metallic support structure has at least one detachment point having an electrical resistance different than an electrical resistance of an adjacent section of the support structure and an electrical resistance of an adjacent section of the metallic component; consolidating the metallic powder with formation of the metallic component and, optionally, with formation of the metallic support structure at least in sections, wherein the metallic support structure connects the metallic component to the build platform; releasing the metallic component from the metallic support structure by bringing about an electrical current in the detachment point.

Abstract: The invention relates to an additive production method involving the production of a layer of geometrically compact particles, having the following steps: a) providing a particle layer depositing arrangement, comprising a first and a second semi-chamber, wherein a partition separates the first semi-chamber from the second semi-chamber, and the partition is permeable for a dispersion medium and impermeable for particles dispersed in the dispersion medium; b) providing a particle dispersion comprising the dispersion medium and particles dispersed therein in the first semi-chamber, the particle dispersion being distributed substantially homogenously in the first semi-chamber; c) generating a pressure gradient between the first and the second semi-chamber such that the pressure gradient in the first semi-chamber causes a particle dispersion flow directed towards the partition; and d) depositing a particle aggregate material comprising geometrically compact particles on the partition by transporting a dispersion a
