A method for the additive manufacturing of an elastomer part, includes—the creation of a model of spatial coordinates of the part; followed by—the corresponding deposition of an elastomer material. The deposition is carried out in a plurality of substantially flat layers which are vertically stacked. The elastomer material is deposited in the form of a latex-based liquid composition having a dispersion of polymers in an aqueous base, and the deposition is carried out by formation and pressurized ejection of drops of a liquid composition.

The present invention discloses a colorful board structure comprising a transparent substrate, an adhesive layer, a three-dimensional painted layer and a protective layer. The three-dimensional painted layer includes at least one colored layer and at least one transparent stacking layer including at least one raised part. The aforementioned colorful board structure is made of a multi-layer structure, and has the advantages of enhancing the stereoscopic effect of the pattern and the color expression. In addition, a manufacturing method of the colorful board structure is also disclosed.

In exemplary implementations of this invention, an actuated fabricator deposits structural elements (e.g., tensile structural elements) in a 3D pattern over large displacements. The fabricator is supported by at least three elongated support members. It includes onboard actuators that translate the fabricator relative to the ends of the support members. The fabricator is configured, by actuating different translations along different support members, to translate itself throughout a 3D volume. In some implementations, each of the actuators use fusible material to fuse metal tapes together, edge-to-edge, to form a hollow structure that can be shortened or lengthened.

A solid object shaping apparatus can shape a solid object having a designated color, and includes a head unit that can eject a plurality of types of liquids including a first liquid used to represent the designated color and a curing unit that cures the plurality of liquids so as to form a plurality of blocks including a first block. The blocks include a first surface block whose upper face or lower face corresponds to a surface of the solid object and a second surface block whose side face corresponds to the surface of the solid object. When the solid object is shaped, the number of the first blocks used in a predetermined area formed by an upper face of the first surface block is different from the number of the first blocks used in a predetermined area formed by a side face of the second surface block.
