    Abstract: According to examples, a three-dimensional (3D) fabrication system may include a controller that may control an agent delivery system to deposit a fusing agent onto a fusing area of a layer of particles of build material. The controller may also control the agent delivery system to deposit an energy absorbing agent onto an unfused thermal support area of the layer of particles, the unfused thermal support area being located adjacent to the fusing area. The controller may further control an energy supply system to supply energy, in which supply of the energy is to cause the particles on which the fusing agent has been deposited to melt and a temperature of the particles in the unfused thermal support area to be raised to a level that is below a melting point temperature of the particles.

    Abstract: A system and method for providing three dimensional printing production quality prediction is described herein. The system may include logic to scan a region of interest associated with a layer of a plurality of parts during printing to obtain an input for the region of interest and compute an input metric associated with the layer based on the input. In response to an initial set of print jobs, at least a portion of the plurality of parts is mechanically tested to determine at least one output. In response to a production print job, a likelihood of a part of the plurality of parts to satisfy a quality specification is predicted by inputting the input metric to at least one machine learning function comprising the at least one output, wherein the at least one machine learning function is trained during the initial set of print jobs.

    Abstract: A hybrid connection for connecting a first portion of a three-dimensional (3D) print design to a second portion of the 3D print design may include a cross-sectional pattern of fully-fused connections and under-fused connections that connect between the first portion of the 3D print design and the second portion of the 3D print design. Systems and methods are also described herein that facilitate designing 3D parts with hybrid connections and/or automatically replacing fully-fused connections with hybrid connections.

    Abstract: According to examples, an apparatus may include a fabricating system, a processor, and on memory on which are stored machine readable instructions. The instructions, when executed by the processor, may cause the processor to control the fabricating system to spread a first layer of build material as part of an object fabrication process, the build material comprising particles or a paste. The instructions may also cause the processor to control the fabricating system to selectively solidify a first area of the layer to a higher degree of solidification than a predefined second area encompassed by the first area, in which the predefined second area has a lower fracture toughness than the first area to propagate a crack in the object more readily than the first area.

    Abstract: A spherical identifier may, in an example, include a sphere including a plurality of shells forming the sphere, a radially-defined code being discernable using the arrangement of the plurality of shells. A three-dimensional object identifier may, in an example, include a number of spheres manufactured into the body of the three-dimensional object wherein each of the spheres comprise a plurality of shells; the shells constituting a radially definable code.

    Abstract: An example technique for generating slice data from a voxel representation can include obtaining a shape specification of the 3-D object. The example technique for generating slice data from a voxel representation can also include obtaining a material specification of the 3-D object. The example technique for generating slice data from a voxel representation can also include merging the shape specification and the material specification to create a voxel representation of the 3-D object, wherein each voxel in the voxel representation includes a plurality of data types. The example technique for generating slice data from a voxel representation can also include generating slice data from the voxel representation, wherein the slice data provides a higher resolution than that provided by the voxel representation using the plurality of data types.
