A three-dimensional molding apparatus is provided and includes a reservoir portion, a nozzle portion, a liquid-sending unit, and a temperature control unit that correspond to each of the two or more different types of materials, a molding stage, a relative movement mechanism for moving the stage and the nozzle portions, and a control computer. By using this apparatus, industrial additive manufacturing with two or more different types of materials can be realized with high precision, and high-definition molded products in which different types of materials are arbitrarily combined can be produced.

An MFD is disclosed. For example, the MFD includes a color printhead to dispense color printing fluid, an enhancement printhead to dispense a three-dimensional (3D) print material, a processor and a non-transitory computer-readable medium storing a plurality of instructions. The instructions when executed by the processor cause the processor to perform operations that include printing a two-dimensional (2D) image on a substrate and printing a 3D object on the 2D image printed on the substrate such that colors of the 2D image provide a desired color for a desired portion of the 3D object.

The invention comprises a 3D printer for additively manufacturing a multilayer component. The 3D printer comprises at least two separate dispensers (2) coating a conveyor belt (3) with respectively different raw material, a manufacturing unit in which at least part of the raw material is added to the component (8) as a new layer, at least two separate recovery devices (12) for selectively recovering the respectively different raw material, which is not consumed when a layer is added to the component (8), and returning the raw material to the respective associated dispenser (2) and conveyor belt (3) which transports the raw material from the dispenser (2) to the manufacturing unit and further to the recovery device (12) in the lateral direction.

The invention relates to a device and method for preparing a structure or object using an additive manufacturing process referred to as sequential cold spray laser sintering. The method includes depositing by cold spraying a plurality of sequential layers of material onto a substrate/build plate or particles of materials onto a compacted powder bed of material and employing an energy source to sinter or melt each of the plurality of sequential layers or powders to produce sequential sintered layers, wherein the number of additional layers is determined based on those needed to produce the final structure.

Methods of fabricating three-dimensional objects featuring properties of a soft bodily tissue and three-dimensional objects featuring properties of a soft bodily tissue or of an organ comprising same are provided.

A computer system performs corrective operations during a three-dimensional (3D) printing job. The 3D printing job is initiated to produce a physical object. Printing of the physical object is monitored to identify a defect of the physical object during the printing. The defect is analyzed to determine one or more corrective operations to apply to the physical object. The one or more corrective operations are performed during the printing. Embodiments of the present invention further include a method and program product for performing corrective operations during a 3D printing job model in substantially the same manner described above.
