3D printer of double cycle heating constant temperature forming space

Abstract

The invention belongs to the field of 3D printing equipment, and discloses a 3D printer of double cycle heating constant temperature forming space. The 3D printer comprises a constant temperature boxbody, a printing worktable and a printing head are arranged in the constant temperature box body, at least two circulation air flues are arranged on the side wall of the constant temperature box body,the printing worktable is driven by a first drive mechanism to move along the Z axis, the printing head is driven by a second drive mechanism to move along the X axis and the Y axis, and the first drive mechanism and the second drive mechanism are arranged on the outer side of the constant temperature box body. The 3D printer of double cycle heating constant temperature forming space is stable incontrol, the effect of high temperature on a power drive mechanism is avoided, and the service life of the printer is prolonged.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a 3D printer with double-cycle heating and constant temperature molding space. Background technique [0002] The 3D printer based on the fused accumulation rapid prototyping process uses plastic filaments with a diameter of about 1-2 mm, and melts and extrudes the plastic filaments into filaments of about 0.2-0.4 mm through a computer-controlled printing extrusion head and scans them layer by layer. Print stacks into three-dimensional objects. [0003] The temperature control of the molding space of the 3D printer has a very important influence on the mechanical properties and molding accuracy of the printed three-dimensional objects. During the printing process, there will be two phase transition processes. The first is that the material is heated and melted from a solid filament to a molten state, and the second is that the molten state is extruded through a nozzle and the...

Problems solved by technology

[0005] The second solution is to heat the entire molding space. The hot air of the heating system cannot circulate, resulting in uneven heating and cooling of the space, affecting the printing accuracy of the model, and even causing printing failure. At the same time, many structural parts and electrical components are installed in the molding space. The temperature is high, the structural parts and electrical parts are exposed to high temperature environment, the working performance and service life will be greatly reduced
