Abstract: In an example, a method includes analysing, using at least one processor, object model data representing at least a portion of an object to be generated by an additive manufacturing apparatus by fusing a build material to determine at least one predicted object generation temperature. The method may further include identifying, using at least one processor and from said analysing, a feature of the at least a portion of the object associated with a predicted object generation temperature which is below a fusing temperature of build material to be used in object generation. The method may further include determining, using at least one processor, modification data to be used in object generation, the modification data being to increase a temperature of the feature in object generation.

Abstract: An airborne particle detector comprises a light source to emit a light beam through a target space adjacent to a heat source of a 3D printer, a detector to detect an amount of light of the light beam having passed through the target space, and a detection engine in communication with the light source and the detector to detect airborne particles in the target space using an amount of light detected by the detector.

Abstract: Misalignments of a 3d printing device may be detected by providing a reference pattern in a print zone of the 3d printing device, wherein the reference pattern comprises a plurality of reference marks, printing a test pattern on the reference pattern by means of the 3d printing device, and comparing the test pattern with the reference marks.

Abstract: A first number of color patches are printed with a target printing system to obtain a sparse color gamut characterization. A second number of color patches are printed with a reference printing system to obtain a reference color gamut characterization. The second number is greater than the first number. A dense color gamut characterization is generated with a transformation of the reference color gamut characterization to the sparse color gamut characterization. A color management resource can be generated for the target printing system from the dense color gamut characterization.

Abstract: There is provided a method of generating print data for use by an additive manufacturing system to generate a plurality of 3D objects within a build chamber having a build surface. First spatial data defining a first 3D object and second spatial data defining a second 3D object is received. First print data is generated to cause the additive manufacturing system to manufacture the first 3D object at least partly from a first build material. Intermediate print data is generated to cause the additive manufacturing system to manufacture a partition comprising a 3D object configured to fill the build chamber in a plane parallel to the build surface. Second print data is generated to cause the additive manufacturing system to manufacture the second 3D object at least partly from a second build material.

Abstract: There is disclosed a build material supply unit, comprising: a supply chamber body enclosing a supply volume to contain a build material for additive manufacture; an electromagnetic distance sensor to determine a length parameter relating to a length of a beam pathway extending from an emitter of the sensor to a surface level of build material in the supply volume; and a reflector to reflect the beam pathway between the emitter and the surface level of build material; wherein the reflector is spaced apart from the emitter.

Abstract: An example disclosed herein analyzes a first scan of a first target scanned with a first scanner module of a scanner, analyzes second scan of a second target scanned with a second scanner module of the scanner, identifies a color difference greater than a threshold color difference between the first scan and the second scan, and adjusts color settings for the first scanner module to correct the color difference to less than the threshold color difference.
