Description

Technical Field

[0001] The invention relates to the technical field of 3D printing, and in particular to an FDM type 3D printer suitable for high-temperature printing. Background Art

[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology. This technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automobiles, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.

[0003] Most of the FDM 3D printers currently used in the market do not have matching heat dissipation equipment. Because the temperature inside the nozzle needs to be maintained, the nozzle has a good thermal insulation effect. After the 3D printer is used, it can only be placed for a long time to wait for the equipment to dissipate heat by itself. Such poor heat dissipation effect will cause damage to the parts inside the nozzle, affecting the service life of the nozzle, thereby causing inconvenience to the staff. Summary of the invention

[0004] In view of this, the object of the present invention is to provide an FDM type 3D printer suitable for high temperature printing to solve all or one of the problems mentioned in the above background technology.

[0006] Optionally, there are two heating blocks, and two sides of the nozzle are fixedly connected to the two heating blocks respectively.

[0007] Optionally, a second slide groove is provided inside the shell, a second slider is movably connected inside the second slide groove, and one side of the second slider is fixedly connected to one side of the baffle.
