Certain examples described herein relate to structure forming for the production of a three-dimensional object. In these examples, different structure forming components or functions are applied to volumes of a three-dimensional object. These structure forming components or functions are arranged to differentially generate a halftone output. The halftone output is generated by processing a material volume coverage representation for the three-dimensional object. The halftone output is used to provide control data for instructing production of a three-dimensional object.

An adjustable level 3-D printing platform includes a platform, three support posts, and an adjusting component by which heights of the three support posts are adjustable. The bottom of the build platform includes at least one socket to engage with a ball end of one of the three support posts, thereby enabling two point leveling. The adjusting component is configured to simultaneously adjust a height of the at least three support posts using a first arm and a second arm, each connected to the build platform at respective pivot points and configured to apply respective clamping forces to the support posts. The printing platform further includes at least one sensor leveling system that deploys a probe, measures a relative probe state, and compares the measurement to a predetermined value. During the leveling processes, the 3-D printer is configured to provide sensory feedback.

A method for manufacturing a three-dimensional object includes converting model data of the three-dimensional object into slice data, sintering powder based on the slice data after the conversion, and manufacturing the three-dimensional object by a layered manufacturing process of stacking a plurality of sintered layers. The method includes a part data correction process of correcting positional information of at least one of mutually adjoining part data of the model data of the three-dimensional object, and laying part data on each other by a predetermined amount of overlap, converting the model data corrected in the part data correction process into slice data, and after forming a sintered layer based on the slice data corresponding to one part, forming a sintered layer based on the slice data corresponding to the other part.

Systems and methods are provided for composite part design. One embodiment is a method for selectively analyzing feasibility of optimizing fiber orientations for layers of a multi-layer composite part subdivided into panels that each comprise a fraction of an area of the composite part. The method includes identifying stacking sequence rules that constrain the composition of sublaminates that comprise consecutively stacked layers utilized during optimization, for each panel of the composite part, analyzing the panel by identifying ply counts that constrain a number of plies at the panel, selecting a number of sublaminates to utilize during optimization of the panel, calculating ply count ranges for a laminate, based on the number of sublaminates and the stacking sequence rules, and determining whether the ply counts for the panel comply with the ply count ranges for the laminates.

The method comprises following steps of: building a color 3D object into a coloring model; dividing the coloring model into a plurality of color cells, wherein a shell of each of the color cells forms an accommodating space configured to accommodate a color material; setting respectively the color of the color material accommodated by each color cell according to the color of the color 3D object and generating a printing color data corresponding to the color 3D model; generating a printing object data associated with the printing color data according to the color cells. The disclosed example can effectively realize the printing of the color 3D model through the inkjet manner via generating color cells configured to accommodate color materials.

Method and computer-readable model for additively manufacturing a ducting arrangement in a combustion system of a gas turbine engine are provided. The ducting arrangement may be formed by duct segments (32) circumferentially adjoined with one another to form a flow duct structure (e.g., a flow-accelerating structure (34)) and a pre-mixing structure (35). The flow duct structure may be fluidly coupled to pass a cross-flow of combustion gases. The pre-mixing structure (35) may include an array of pre-mixing tubes (48) fluidly coupled to receive air and fuel conveyed by a manifold (42) to inject a mixture of air and fuel into the cross-flow of combustion gases that passes through the flow duct structure. The duct segments or the entire ducting arrangement may be formed as a unitized structure, such as a single piece using a rapid manufacturing technology, such as 3D Printing/Additive Manufacturing (AM) technology.

A method for computer numerically controlled processing may include receiving configurations for a fabrication in which a computer numerically controlled machine processes a material to achieve one or more designs. An analysis may be performed to determine whether a thermal event occurs during the fabrication. The analysis may include performing one or more of a time-variant simulation and a time-invariant simulation of the fabrication. The thermal event may include one or more regions of the material exhibiting an undesirable response to the electromagnetic energy delivered to the material. One or more outputs may be generated based on the result of the thermal verification. The outputs may include a visualization of the quantity of energy exposure across the material, an alert if a thermal event is determined to occur during the fabrication, and corrective actions for resolving potential thermal events.

Generating tool path data for an additive manufacturing apparatus comprises providing object design data in which at least a part of a physical object is represented by a line. A section of the line is then sliced using an intermediate slicing layer that is provided between first and second physical build layers of the additive manufacturing apparatus. The slicing generates an intermediate layer point at the intersection of the section of the line and the intermediate slicing layer, with the intermediate layer point being located between the first and second physical build layers. The intermediate layer point is then projected to a projected build layer point that lies within a physical build layer of the additive manufacturing apparatus. The projected build layer point is used to provide tool path data for that physical build layer. A similar process can be used in which the physical object is represented by a surface.

Systems and methods are provided for three-dimensional (3D) printing with three-dimensional (3D) model cuts based on anatomy, in particular during medical imaging operations.

A data processing apparatus includes: a receiving unit: that receives first data defining a shape and a color of a three-dimensional object; and a generating unit, wherein when two or snore color components interfere with each other in one voxel as a result of performing a halftoning process for each of plural color components based on color information in the first data, the generating unit generates color voxel data by assigning any one of the two or more color components as color information of the one voxel and assigning the remaining color components of the two or more color components as color information of voxels present around the one voxel.
