3D printer workbench

Abstract

The invention provides a 3D printer workbench which comprises a printing platform under a 3D printer spray head and a cleaning mechanism for cleaning residues on the printing platform, wherein the cleaning mechanism and the printing platform are movably connected; the printing platform comprises a bottom plate, a thermal insulation layer, a constant temperature layer and a panel which are sequentially stacked from bottom to top; the constant temperature layer comprises a plurality of constant temperature plates which are arranged on the same horizontal plane in parallel and thermal insulation stripes arranged between every two thermal insulation plates, and each constant temperature plate is connected with a control unit which is used for controlling a temperature of the constant temperature plate. The workbench disclosed by the invention has a high residue cleaning efficiency and saves time and labor; a temperature of a contact face between a printed product and the panel is even to avoid the edge warping phenomenon, so that printing quality is improved; by controlling switches and temperatures of different constant temperature plates, energy waste caused by wholly heating the panel is avoided.

Description

technical field [0001] The invention relates to a 3D printer workbench. Background technique [0002] 3D printer, also known as three-dimensional printer, is a machine 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. It is a cumulative manufacturing technology that creates three-dimensional objects by printing layers of adhesive materials. The basic principle is that by putting data and raw materials into the 3D printer, the machine will build the product layer by layer according to the program, and The product is printed out and ready for immediate use. 3D printers used to be used to make models in the fields of mold making, industrial design, etc., and are now gradually being used for direct manufacturing of some products, which can be used in jewelry, footwear, industrial design, architecture, engineering and construction, automo...

AI Technical Summary

Problems solved by technology

At present, the workbench of 3D printers on the market is usually made of metal aluminum plate. Although the surface is flat and smooth, due to the phenomenon of uneven heating in its own structure, the product is heated unevenly when the printer is printing, and the separated temperature sensor cannot be timely and accurate. Feedback of the real-time temperature of the heated bottom plate is extremely easy to cause warping of the printed product, which seriously affects the printing quality
