The second unit comprises a fourth movable portion, a fourth forming portion, a fifth forming portion, a sixth forming portion, and a plurality of assembling portions. The fourth movable portion is configured to move so as to switch at least one assembling portion opposed to at least one first forming portion, at least one other assembling portion opposed to the at least one second forming portion, and at least one remaining assembling portion opposed to at least one third forming portion.

A method of manufacturing a three-dimensional shaped object, which is a method of shaping a three-dimensional shaped object using a cutting tool configured to cut a first length in a cutting direction, includes: a first portion shaping step of stacking a shaping material to shape a first portion having a length in the cutting direction shorter than the first length; a first portion cutting step of cutting the first portion in the cutting direction by the cutting tool; and a second portion shaping step of stacking the shaping material to couple to a first end surface of the first portion in a direction opposite to the cutting direction, and to shape a second portion having a length in the cutting direction shorter than that of the first portion.

The present invention provides a synthetic resin molded product reusing plastic waste including a plurality of kinds of plastics mixed therein (such as ocean plastic trash, and hardly classifiable plastic trash in industrial waste or general waste) as raw materials, and having a high sense of design, and provides a manufacturing method thereof. The molded product is characterized by being molded with a powder of plastic waste including a plurality of kinds of plastics mixed therein, and a powder of a second material (such as a woodchip) not molten under a temperature condition of 200° C. as raw materials, and is characterized in that a large number of spots 33 different in color and/or glossiness from a base color of the molded product (deck material 31) are scattered at random on a surface of the molded product, and in that a stipple pattern is formed on the surface of the molded product.

Embodiments of the present disclosure are drawn to additive manufacturing apparatus and methods. An exemplary additive manufacturing method may include forming a part using additive manufacturing. The method may also include bringing the part to a first temperature, measuring the part along at least three axes at the first temperature, bringing the part to a second temperature, different than the first temperature, and measuring the part along the at least three axes at the second temperature. The method may further include comparing the size of the part at the first and second temperatures to calculate a coefficient of thermal expansion, generating a tool path that compensates for the coefficient of thermal expansion, bringing the part to the first temperature, and trimming the part while the part is at the first temperature using the tool path.

In a metal fiber composite (MFC) additive manufacturing (AM) method, a layer of polymer structures is deposited using a fused filament fabrication (FFF) printer assembly comprising at least one nozzle. Subsequently, an MFC printer assembly is used to embed a continuous metal fiber into one or more of the polymer structures of the layer. The embedding is achieved by heating the metal fiber and applying pressure to the metal fiber using an embedding surface of the MFC printer assembly. The heated metal fiber melts polymer adjacent thereto, thereby allowing the pressure to embed the metal fiber into the polymer structure. Using the MFC-AM method, various composite structures can be formed, such as novel heat exchangers that may otherwise be difficult or impossible to fabricate via other manufacturing techniques.
