Large-storage-amount parallel-arm 3D printing machine with charging barrel separated from nozzle

Abstract

The invention discloses a large-storage-amount parallel-arm 3D printing machine with a charging barrel separated from a nozzle, and belongs to the technical field of 3D printing machines for high-viscosity materials. The 3D printing machine comprises an outer frame part, three kinematic pair parts, a driving part, an extrusion head part and a storing and conveying part. The three kinematic pair parts are uniformly installed at three corners of the outer frame part. The storing and conveying part is installed at the top of the outer frame part. The driving part is installed at the bottom of the outer frame part. The extrusion head part is connected with the storing and conveying part and the three kinematic pair parts. According to the large-storage-amount parallel-arm 3D printing machine with the charging barrel separated from the nozzle, the defects that a charging barrel and nozzle integrated type printing machine on the market is large in motion inertia, poor in dynamic property and the like are overcome, the positioning precision is high, the printing head response speed and the printing speed are high, the 3D printing machine is not limited by the size of a 3D printing structure any more, and the size of a target object capable of being printed is increased.

Description

technical field [0001] The invention relates to a device capable of 3D printing high-viscosity fluid materials obtained by heating foods, medicines, gypsum, etc., especially a high-storage parallel-arm 3D printer with separate barrels and nozzles. Background technique [0002] With the rapid development of digital technology, 3D printing technology has been realized and has a wide range of applications in various fields. Most of the research on 3D printing technology focuses on metals and plastics, and there are not many studies on printing high-viscosity fluids obtained by heating food and medicinal materials. At present, the 3D printers for high-viscosity materials on the market usually design the barrel and the nozzle as one for the convenience of material feeding. In the parallel arm structure, the design of the barrel and the nozzle as one will increase the load of the print head and cause the movement of the print head. The larger the inertia, the lower the positionin...

Problems solved by technology

At present, the 3D printers for high-viscosity materials on the market usually design the barrel and the nozzle as one for the convenience of material feeding. In the parallel arm structure, the design of the barrel and the nozzle as one will increase the load of the print head and cause the movement of the print head. The larger the inertia, the lower the positioning accuracy of the printer, the lower the response speed and flexibility of the print head, and the size of the barrel is limited by the structural size of the printer, which reduces the size of the printable object
