Abstract: In an example, a method includes acquiring, by a processor and for a set of locations in a fabrication chamber for additive manufacturing, data identifying a first subset of locations associated with a first level of variability in deformations in object generation and a second subset of locations associated with a second, greater, level of variability in deformations object generation. A geometrical compensation model may be derived to compensate for anticipated deformations in object generation by a first additive manufacturing apparatus. The geometrical compensation model may comprise geometrical transformations to apply to object model data representing at least a portion of an object, wherein each geometrical transformation is associated with a location of the set of locations. The first subset of locations may be associated with geometrical transformations determined based objects generated by a plurality of additive manufacturing apparatus and the second subset of locations may be associated with geometrical transformations determined based on objects generated by the first additive manufacturing apparatus.

Abstract: In an example, a method includes receiving, at least one processor, object model data representing at least a portion of a first object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber. An indication of an amount of fused build material in a region of the fabrication chamber which is to be below the region in which the first object is to be generated may be determined and a dimensional compensation value to apply to the object model data representing the first object may be determined based on the determined indication. The determined dimensional compensation value may be applied to the object model data to derive modified object model data.

Abstract: Example implementations relate to compensating for shrinkage in 3D printing. One example implementation receives an object model to print a corresponding object in a three-dimensional (3D) printer, the object model having a plurality of surface coordinates. A plurality of dimensional modification compensation factors are determined dependent on respective locations within a printing volume of the 3D printer. The object model is adjusted at the plurality of surface coordinates using respective dimensional modification compensation factors depending on the location of the surface coordinates within the printing volume in order to generate a printable object model.

Abstract: A method of configuring an additive manufacturing system. The method comprises configuring the additive manufacturing system with a first value of an operation parameter associated with the additive manufacturing system and, with the additive manufacturing system configured with the first value of the operation parameter, forming, in a build chamber, a first object The additive manufacturing system is subsequently configured with a second value of the operation parameter and, with the additive manufacturing system configured with the second value of the operation parameter, a second object is formed in the build chamber, subsequently to forming the first object. The method further includes receiving a signal indicative of which of the first value or the second value the operation parameter is to be configured with for subsequent operation of the additive manufacturing system.

Abstract: In an example, mesh model data representing at least a portion of a print job to be generated by an additive manufacturing apparatus by solidifying build material is received at a processor. Using a processor and based on the mesh model data, it is validated whether the three-dimensional print job described by the mesh model data conforms with at least one of material-dependent shape constraints and apparatus-dependent shape constraints of the additive manufacturing apparatus. If the result of the validation is positive, the mesh model data is rendered, using a processor for manufacturing the three-dimensional print job by an additive manufacturing apparatus. If the result of the validation is negative, a predetermined action is performed.

Abstract: In an example, a method may include obtaining a first measurement of a first object generated using additive manufacturing apparatus based on object model data and obtaining a second measurement of a second object generated using the additive manufacturing apparatus based on object model data to which a first geometrical compensation parameter has been applied. An effect of the first geometrical compensation parameter may be determined based on the first and second measurements and, based on the determined effect, the first geometrical compensation parameter may be evaluated.

Abstract: In an example, a method includes receiving object model data representing at least a portion of an object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber. At least one of a number of different geometrical compensation models to be applied to the object model data may be selected, where the geometrical compensation models are to determine geometrical compensations to compensate for object deformation in additive manufacturing. An object generation operation based on a modification of the object model data using the or each selected geometrical compensation mode may be simulated and predicted attributes of the object when generated based on the or each simulation may be displayed.
