A shaping method is provided and includes: generating a slice data indicating a cross-section of a shaped object based on a shaped object data, and shaping the shaped object. In a shaped object data preparing step, the shaped object data including multiple pieces of part data is prepared. Each piece of the part data is data indicating at least an outer surface shape of a portion indicated by the part data and a color to be colored on an outer surface. In the slice data generating step, the slice data indicating a cross-section of the shaped object is generated by setting the color of each position of the cross-section corresponding to a portion indicated by each piece of the part data, and a color of an interior of the portion indicated by each piece of the part data is set based on a color set for the outer surface.

A method for three dimensional (3D) printing and a 3D printing device are provided. The 3D printing device includes a modeling printing head, a coloring printing head, and a platform. The modeling printing head and the coloring printing head are co-constructed. The three dimensional printing method includes: printing a forming layer and at least one material barrier outside a bounding area of the forming layer; calculating multiple coloring routes of the coloring printing head according to an edge of the forming layer; converting the coloring routes of the coloring printing head into multiple color-passing routes of the modeling printing head; calculating multiple detour routes of the modeling printing head according to the color-passing routes of the modeling printing head. Each of the detour routes is not the shortest route between a corresponding color-passing route and the next color-passing route, and one of the each of the detour routes and the corresponding color-passing route passes at least one location of the at least one material barrier.

Techniques for integrating a machine-readable matrix with a component of a mechanical structure using three-dimensional (3-D) printing are disclosed. Such techniques include generating at least one data model representing the component, and projecting a matrix pattern identifying one or more features of the component onto a selected surface portion of the component to produce a modified data model for use as an input to a 3-D printer.

A method is provided for producing a three-dimensional object by stacking cured layers of a photocurable color ink composition containing a coloring material. The method includes applying the photocurable color ink composition onto an underlying member; and curing the photocurable color ink composition with light. The content of the coloring material in the photocurable color ink composition is in the range of 0.25% by mass to 2.1% by mass.

A three-dimensional printer and a scanning module thereof is provided. The three-dimensional printer includes a case, a printing platform, a cleaning module, a three-dimensional printing module, a coloring nozzle module and a scanning module. A containing chamber is defined in the case, and a first area and a second area are defined in the containing chamber. The printing platform is arranged in the first area. A portion of the second area is occupied by the cleaning module, and a remaining space is formed by the second area.
