Provided is a system, method, and apparatus for forming surface designs in hard-setting materials. The method includes depositing a hard-setting material mix to create a construction component, controlling a movable unit to manipulate a surface of the construction component with a first profile tool arranged on the movable unit based on surface design data before the hard-setting material mix sets, and controlling the movable unit or at least one other movable unit to manipulate the surface of the construction component with a second profile tool arranged on the movable unit or the at least one other movable unit based on the surface design data before the hard-setting material mix sets, wherein the second profile tool comprises a blade edge and a trowel edge.

A three-dimensional molding apparatus repeatedly discharges a first molding material, which configures the surface layer of a three-dimensional molding and comprises a mechanoluminescent material that emits light upon being subjected to an external force, and a second molding material, which configures internal areas located on the inside of the surface layer of the three-dimensional molding, onto a molding stage to form a molding material layer, and molds the three-dimensional molding by layering multiple molding material layers.

There is provided a manufacturing method of the three-dimensional shaped object, the method being capable of reducing an undesirable phenomenon associated with the contamination of the light transmission window with the fume substance. The manufacturing method according to an embodiment of the present invention is a method for manufacturing a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming, wherein the irradiation with light beam for the solidified-layer forming is performed by directing the light beam into the chamber through a light transmission window of the chamber, and wherein a gas blow is supplied to the light transmission window by use of a movable gas supply device, the light transmission window having been contaminated with a fume generated upon the formation of the solidified layer.

A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.

A three-dimensional object printing system improves the leveling of an object during object printing and removal of waste material during leveling. The printing system includes a material applicator configured to expel material, a member configured to move in a process direction to a position opposite the material applicator to enable the material applicator to expel material onto the member, and a belt assembly. The belt assembly includes a first roller, a second roller, and a continuous belt entrained about the first roller and the second roller. The belt assembly is configured to remove a portion of the material ejected onto the member. The belt assembly is further configured to move the removed portion of the material away from the member.

The present invention lies in the field of 3D printing methods. In particular, the invention relates to 3D printing methods for the production of a 3D part in a layer-by-layer manner, wherein the printable composition is a pasty epoxy composition comprising at least one epoxy resin, at least one monomer and/or prepolymer that is polymerizable by exposure to radiation and at least one photoinitiator, wherein the pasty epoxy composition has a viscosity factor (1.5/15) of at least 2 at application temperature.

The present disclosure describes an apparatus for additively manufacturing a three-dimensional object. The apparatus includes a radiation source, a carrier on which the three-dimensional object is made, an applicator assembly configured to apply a polymerizable liquid, and a frame, with the applicator assembly and the radiation source connected to the frame. A first drive assembly interconnects the applicator assembly and the frame and a second drive assembly interconnects the carrier and the frame. The frame defines a build region between the applicator assembly and the carrier. The applicator assembly includes a polymerizable liquid supply chamber, an application roller, and a metering roller. The applicator assembly may optionally include a post-metering roller. An apparatus comprising a first and a second applicator assembly and a smaller scale version of the apparatus are also described.
