Accurate positioning 3D printer

Abstract

The invention relates to an accurate positioning 3D printer. The accurate positioning 3D printer comprises a base, a support plate, a printing platform, a printing head, an X-axis movement mechanism, a Y-axis movement mechanism and a Z-axis movement mechanism, wherein the X-axis movement mechanism comprises a first motor, a first bottom plate, a first baffle, a first screw rod, a first limiting rod and a first sliding block, the Z-axis movement mechanism comprises a second motor, a second bottom plate, a second baffle, a second screw rod, a second limiting rod and a second sliding block assembly, the second sliding block assembly comprises a second sliding block, a correction unit and a control unit, and the Y-axis movement mechanism comprises a third motor, a third bottom plate, a third baffle, a third screw rod, a third limiting rod, a third sliding block and an adjustment assembly. According to the accurate positioning 3D printer, the positioning accuracy of a Y axis and a Z axis is increased, the adjustment assembly is additionally arranged in the Y-axis movement mechanism, so that the horizontal accuracy of the Y axis can be increased, and the control unit and the correction unit are additionally arranged in the Z-axis movement mechanism, so that the vertical displacement of the Z axis is stable and accurate.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a 3D printer with precise positioning. Background technique [0002] With the development of science and technology, 3D printing technology has been applied in many fields such as jewelry, footwear, industrial design, automobile, etc. 3D printer is a machine of rapid prototyping technology, which is based on a digital model file, using Bondable materials such as powdered metal or plastics are used to construct objects by layer-by-layer printing. [0003] Regardless of additional factors such as cost and raw materials for existing 3D printers, the biggest bottleneck is the lack of printing accuracy, which prevents 3D printing from being scaled up. There are many reasons that affect the accuracy, and the impact on the accuracy of mechanical transmission is irrelevant. neglected part. Contents of the invention [0004] The technical problem to be solved by the present invention is to ...
