An additive manufacturing tool configured to couple to a spindle of a CNC machine, comprises a plurality of drive wheels movable between an engaged position wherein they compress filament from a filament source against a drive disc and a disengaged position wherein they are spaced apart from the filament, and a delivery assembly including a heating element and a nozzle having an outlet opening. When the plurality of drive wheels are in the engaged position and the drive disc is rotated, the filament is drawn into the tool from the filament source and routed around the drive disc to the nozzle, where heat transferred from the heating element to the nozzle melts the filament so that the filament flows through the outlet opening.

A method of forming a molding tool includes performing a computer aided engineering (CAE) analysis on a molding tool design. The CAE analysis predicts flow of injection molded material and a location of gas entrapment within a molding recess of the molding tool design. At least one venting design constraint is applied to the molding tool design as a function of the gas entrapment location. Also, a biomimetic shaped passageway for venting gas away from the gas entrapment location is selected from a plurality of biomimetic shaped passageways. A computational fluid dynamic (CFD) CAE analysis of the molding tool design with the selected biomimetic shaped passageway is performed and modifications of the selected biomimetic shaped passageway are CFD CAE analyzed until a final biomimetic shaped passageway is determined and a molding tool with the final biomimetic shaped passageway is formed.

At least a portion of the plurality of angled struts are internally terminated along the thickness direction of the lattice structure and providing a plurality of internal degrees of freedom towards the first or second surface of the lattice architecture.

A method for manufacturing a decorative material, the method including a step of creating density distribution data having a density value D(x, y) for each two-dimensional position (x, y); a step of converting the density value D(x, y) into a height H(x, y) corresponding to how large the concentration value is; a step of converting the height H(x, y) into a depth F(x, y) that corresponds to the height; a step of forming irregularities on a surface of a material to be a die based on the depth F(x, y) to form the die; and a step of shaping a resin with respect to the irregularities of the die to form irregularities on a surface of the resin.

A method of molding an interior part for a vehicle includes determining a 3D graphic sample model. A shape of the sample model has concave portions having curvatures determined through 3D modeling and gradients of an inner surface of each concave portion. A molded sample having the same general shape as the sample model is injection molded. Information related to scratch occurrence positions is acquired from the molded sample. Information of curvatures and gradients of the concave portions of the sample model are acquired and collected at positions on the sample model corresponding to the scratch occurrence positions. A limit angle and limit angle are determined by using the collected information and preset curvatures for the concave portion of a design of the interior part. The interior part having the concave portion with a shape based on the determined draft angle and the preset curvatures can then be injection molded.
