Novel 3D printing platform

Abstract

The invention relates to a novel 3D printing platform which comprises a fixed base, wherein a printing chamber is fixedly arranged at the top of the fixed base; a placing plate is arranged in the printing chamber; a first stepping motor is fixedly mounted on the left side of the cavity of the fixed base; a vertical screw rod is rotatably arranged on the left side of the cavity of the printing chamber; the output shaft of the first stepping motor is connected with the vertical screw rod; a vertical guide rod is fixedly arranged on the two sides of the vertical screw rod; the left side of the placing plate is connected with the vertical screw rod and the vertical guide rod through a vertical sliding block; a transverse screw rod is symmetrically and fixedly arranged on the two sides of the top of the printing chamber; a transverse guide rod is fixedly arranged on the two sides of the transverse screw rod; a second stepping motor is fixedly mounted on the left side of the printing chamberand is in drive joint with the transverse screw rod; and a transverse sliding block is arranged on the outer side of the transverse screw rod. During the printing process, the printing head displacement is preciser and more stable to reduce the failure rate, and after printing is finished, cooling and solidification of a finished material can be accelerated.

Description

technical field [0001] The invention relates to a novel 3D printing platform, which belongs to the technical field of 3D printing. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing usually uses Realized by digital technology material printers, it is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. Traditional 3D printing heads The displacement device is controlled by three liftable swing arms installed on the outer periphery of the print head. The three swing arms are arranged in a triangle. One end of each swing arm is the driving end to move vertically along the column, and the other end is the linkage end. ...

Traditional 3D printing heads The displacement device is controlled by three liftable swing arms installed on the outer periphery of the print head. The three swing arms are arranged in a triangle. One end of each swing arm is the driving end to move vertically along the column, and the other end is the linkage end. head, the driving ends of the three swing arms respectively lift and adjust the relative position of the print head and the printing platform. This method has limited adjustment accuracy, and the cooling of the material after printing is slow, and it takes a certain amount of time to wait for the formed material to cool before proceeding. next step, thus delaying the operation time
