An additive manufacturing, AM, system (10, 20), comprises a platform (5a) including a mold die (1) mounted on the platform (5a), the mold die (1) having a surface shape corresponding to a mold cavity used for thermoforming a thermoplastic sheet (B), and an AM assembly configured to perform an AM method on a thermoplastic sheet (B) having been thermoformed with the mold die (1). A method (M) for performing additive manufacturing, AM, on a thermoplastic sheet (B), comprises the steps of thermoforming (M1) a thermoplastic sheet (B) using a mold die (1), and performing (M2) an AM method on the thermoformed thermoplastic sheet (B) in the mold die (1) as a substrate.
摘要:
Automatic process control of additive manufacturing. The system includes an additive manufacturing device for making an object and a local network computer controlling the device. At least one camera is provided with a view of a manufacturing volume of the device to generate network accessible images of the object. The computer is programmed to stop the manufacturing process when the object is defective based en the images of the object.

摘要:
One aspect of the disclosure relates to an apparatus (320) including an extrusion nozzle (300). The nozzle (300) includes an inlet end, an outlet end opposite the inlet end and an axis (303) extending between the inlet end and the outlet end. The extrusion nozzle (300) is configured to rotate about the axis (303). The extrusion nozzle (300) also includes a rotary drive engagement portion (305) between the inlet end and the outlet end. The extrusion nozzle (300) further includes a cavity (304) including an inlet opening (304A) at the inlet end and an outlet opening (304B) at the outlet end. The inlet opening (304A) has a different configuration than the outlet opening (304B).
摘要:
The invention relates to a concave-convex nozzle plate (4) having an arrangement of the nozzles (3) on the convex side. Said nozzle plate and an extrusion device (2) equipped therewith is suitable for extruding plastic melts in strand granulation.
