High-precision sinking photocuring 3D printer

Abstract

The invention discloses a high-precision sinking photocuring 3D printer, and relates to the technical field of 3D printers. The high-precision sinking photocuring 3D printer comprises a rack and a resin groove arranged on the rack, wherein an opening of the resin groove is vertically arranged upwards, and a printing table which slides in the resin groove in the vertical direction is arranged on the rack. According to the high-precision sinking photocuring 3D printer, a scraping plate is arranged, a motor is controlled to rotate forwards and reversely, the scraping plate is driven to slide backand forth in the length direction of guide rails, resin can be spread all the time in the printing process, and then the resin is uniformly spread on the current printing layer, so that the printingprecision is effectively guaranteed; after printing is finished, the scraping plate made of rubber completes unloading on a printing piece on the printing table, so that manual unloading is avoided, and safety and convenience are achieved; and an adjusting block and a mounting plate are arranged, only the adjusting block needs to be replaced, the distance between the bottom of the scraping plate and the printing table can be adjusted, the scraping plate and the mounting plate are detachably connected, and replacement and maintenance of the scraping plate are also very convenient.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a high-precision sinking light-curing 3D printer. Background technique [0002] The existing photocuring 3D printing technology is mainly based on the principle of lamination manufacturing. The computer obtains the solidified geometric parameters of each layer by layering the 3D model, and then constructs the object by printing layer by layer. This layer-by-layer printing method is limited by the printing accuracy. It is necessary to reduce the thickness of a single layer to ensure the printing accuracy. It usually takes a lot of time to complete the printing project. [0003] The invention patent with the notification number CN105437547B provides a continuous sinking high-efficiency 3D printing method and equipment, including a closed material trough and a light source arranged above the closed material trough, and a printing platform is slid and connected in the closed mat...

AI Technical Summary

Problems solved by technology

[0004] During the printing process, the resin above the printing table will be cured and formed, but the following disadvantages are found during use: 1. Due to the poor fluidity of the resin, the resin cannot be spread evenly on the printing table, which affects the printed image. Product accuracy and product quality cannot be guaranteed; 2. When the cured printed parts are unloaded on the printing table, the operator usually needs to shovel them off the printing table with tools such as shovels. Although the resin has high strength and good toughness

However, this process is easy to cause damage to the printing platform, and because the photosensitive resin is volatile, it will produce pungent gas. Even if the resin used in the latest technology has been non-toxic, it will still make the operator feel uncomfortable. unwell
