Abstract
The invention relates to a computer-assisted method for examining an input data set of a generative layer building device, comprising at least the following step: —comparing at least one parameter value in a computer-based model of an object that is to be produced using said generative layer building device, to a limiting parameter value which is an extreme value for the parameter able to be obtained in a method for producing the object, and particularly an extreme value for the parameter that can be obtained in a process-stable manner.
Claims12
A layer-wise additive manufacturing method of manufacturing at least one three-dimensional object by layer-wise solidification of a building material in powder form or a liquid building material in a layer-wise additive manufacturing device, the layer-wise additive manufacturing device comprising a building support for supporting the at least one object to be manufactured, an application device for applying a layer of the building material in powder form or the liquid building material on the building support or on a previously applied and selectively solidified layer of the building material, a selective solidification device that is able to act on all positions in the applied layer that correspond to a cross-section of the at least one object to be manufactured such that the building material at the positions coalesces to a solid state body, and a control unit that controls the application device and the selective solidification device such that the object is manufactured by a successive selective solidification of layers of the building material, the method comprising:
- examining, with a computer-based method, an input data set for controlling the layer-wise additive manufacturing of an object by the layer-wise additive manufacturing device, the step of examining including comparing at least one parameter value in a computer-based model of the object to be manufactured to a limit parameter value specified for the layer-wise additive manufacturing device, the limit parameter value being an extreme value for the parameter that is realizable in a stable process when the object is manufactured by the layer-wise additive manufacturing device,
- wherein when the result of a comparison is that a parameter value lies beyond a corresponding limit parameter value, an adaptation of the parameter value is carried out automatically and/or with interaction with a user.
A layer-wise additive manufacturing device for manufacturing at least one three-dimensional object by a layer-wise solidification of a building material in powder form or a liquid building material, the layer-wise additive manufacturing device comprising:
- a building support for supporting the at least one object to be manufactured;
- an application device for applying a layer of the building material in powder form or the liquid building material on the building support or on a previously applied and selectively solidified layer of the building material;
- a selective solidification device that is able to act on all positions in the applied layer that correspond to a cross-section of the at least one object to be manufactured such that the building material at the positions coalesces to a solid state body;
- and
- a control unit that controls the application device and the selective solidification device such that the object is manufactured by a successive selective solidification of layers of the building material,
- wherein the layer-wise additive manufacturing device comprises an examination device for examining an input dataset of the layer-wise additive manufacturing device and/or is connected to such an examination device in terms of signaling,
- the examination device comprising:
- a comparison unit that compares at least one parameter value in a computer-based model of the object to be manufactured by the layer-wise additive manufacturing device to a limit parameter value specified for the layer-wise additive manufacturing device, the limit parameter value being an extreme value for the parameter that is realizable in a stable process in a method used for the manufacturing of the object,
- wherein when the result of a comparison is that a parameter value lies beyond a corresponding limit parameter value, an adaptation of the parameter value is carried out automatically and/or with interaction with a user;
- a storage unit in which the computer-based model of an object to be manufactured by the layer-wise additive manufacturing device is stored;
- and
- a storage unit in which the at least one limit parameter value is stored.
