FDM 3D printer with heating thermal insulation property

Abstract

The invention discloses a FDM3D printer with heating and heat preservation performance, which comprises a casing, the casing includes a lower casing and an upper casing fixedly connected above the lower casing; an upper front door is installed directly in front of the upper casing, and the lower casing The lower front door is installed directly in front of the front; the upper shell and the lower shell are set as a rectangular parallelepiped structure without a front face; The double-layer structure, the double-layer structure includes the outer sheet metal shell and the inner sheet metal plate; the double-layer structure on the upper left side and the upper right side is equipped with an air duct; the upper end of the air duct is equipped with a heater, and the lower end is It is equipped with a turbo fan; it reduces the heat exchange between the printer's printing chamber and the outside air, so that the hot air in the printer is not easy to flow out from the sheet metal gap; and heats the air in the upper casing, and makes the printing chamber reach the preset goal After the temperature value, it is in a state of constant temperature and uniformity.

Description

technical field [0001] The invention belongs to the technical field of FDM3D printers, and in particular relates to an FDM3D printer with heating and heat preservation performance. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond materials, which create three-dimensional objects by printing layers of adhesive materials. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. [0003] At present, the traditional FDM 3D printers on the market are basically open or acrylic or single-layer sheet metal as the shell...
