Method and machine for additive manufacturing of materials

A machine for additive manufacturing materials, with a cavity and a powder material supply of an additive manufacturing device, a sinter/melting device and a control unit, which form a functional unit for the additive manufacturing which is configured such that under a control sovereignty of the control unit and based on a “Powder Bed Fusion technique

• powder material is fillable into a powder material bed,
• the powder material is used by way of sintering or melting through the sinter/melting device to build up within the powder material bed layer by layer an additive manufactured object on the build platform, which is both, moveable downwards tweew or moveable upwards and tiltable clockwise or tiltable counter-clockwise How, in the cavity, thereby changing a filling volume of the powder material bed (PMB) for the powder material,
• a simulation model including a digital-twin of the additive manufactured object and assigned to the control unit to execute under the control sovereignty of the control unit the sintering or melting based build-up through the sinter/melting device. and
• tilting under the control sovereignty of the control unit and according to the simulation model the build platform within the cavity such that during the layer by layer build-up an overhang angle as a maximum allowable additive manufacturing angle either referring to an additive manufacturing level is not undershot or referring to an additive manufacturing direction is not exceeded.
