Abstract: A powder supply system for supplying powders by a transmission structure includes a first stock bin, a driven member, a driving medium, and a second stock bin. The first stock bin includes an outlet, the driven member is arranged at the outlet, and the driven member includes a powder holding area configured for receiving the powders discharged from the outlet. The outlet is arranged opposite to an inlet of the second stock bin, the second stock bin can drive the driving medium to contact the driven member when moving to a discharge range corresponding to the outlet, and the driven member can discharge the powders in the powder holding area into the second stock bin by the driving medium driving the driven member. A three-dimensional printer is also disclosed.

Abstract: This disclosure provides a powder compaction assembly, a powder laying mechanism, and an additive manufacturing equipment. The powder compaction assembly includes a mounting frame, a powder compaction roller, a scraper, and a rotary member. The mounting frame is rotatably disposed in the mounting frame. The scraper is connected to the mounting frame along an adjusting direction removable. The adjusting direction and the molding surface are perpendicular or intersecting. The scraper is separable from the powder compaction roller. The rotary member is connected to the mounting frame rotationally and fitted with the scraper. The rotary member is configured to rotate relative to the mounting frame and drive the scraper to move along the adjusting direction, and adjust distance between the scraper and the molding surface along the adjusting direction.

Abstract: A 3D printer system that uses the AM method to print a product using a plurality of materials, each of which is contained in a respective capsule. The capsules are removably inserted into respective capsule holders, each of which includes a heating device for adjusting the temperature of the material, and is releasably held in one of a plurality of stations. A tool fetches individual capsules from and deposits them to their stations, and holds individual capsules for printing the product using a telescopic extrusion apparatus. A memory stores capsule-identifying data, a processor provides position coordinates for positioning of the tool, and a controller moves the tool to the position coordinates. The capsule holders include heating systems for controlling the rheological behavior of the materials based on algorithms executed by the processor.

Abstract: A belt adjusting device of a printer includes a bracket, a base, a driving device, and a resisting member. The bracket includes a bottom wall and a belt placed on the bottom wall. The belt is loop-shaped. The base is slidably mounted to the bracket. The driving device is mounted to the base and includes an eccentric device engaging with the belt. The resisting member resists the driving device to enable the eccentric device to rotate to adjust the belt when the base slides relative to the bracket.

Abstract: A printer includes a hanger, a printer head, a carriage, and an adjustment assembly. The hanger includes a base and a board above the base. The carriage includes a body, a rod, and an actuator. The body is rotatably connected to the rod. The actuator is rotatably connected to the body. The actuator includes a projection and a resisting member. The adjustment assembly includes a protruding post. When the body moves in a first direction, the projection applies a push force to the protruding post, the protruding post rotates downward. When the body moves in a reverse, second direction, the protruding post applies a push force to the projection, which causes the actuator to rotate, the lateral surface of the resisting member stays in contact with the board during the rotation of the actuator, causing the carriage to rotate, the distance between the printer head and the base is changed.
