SLA equipment for forming high-viscosity slurry and control method for slurry forming

Abstract

The invention discloses SLA equipment for forming high-viscosity slurry, which includes a forming chamber, a laser through hole is arranged on the top of the forming chamber, an optical system is installed on the top of the laser through hole, and a feeding bin, a forming There is a lifting platform a in the feeding warehouse, a lifting platform b in the forming warehouse, the laser through hole is facing the lifting platform b, a scraper module is installed in the forming room, the optical system, the scraper module, the lifting platform a and The lifting platform b is connected with a control system. The invention also discloses a control method for forming the slurry, which solidifies and forms the high-viscosity slurry through the coordinated action of the optical system, the feeding bin, the forming bin, the receiving bin and the scraper module. The SLA equipment of the present invention evenly spreads the high-viscosity slurry on the lifting platform b through the horizontal movement of the scraper and the vertical movement of the push plate, effectively avoiding the high-viscosity slurry from sticking to the scraper and causing the lack of material in the forming substrate The problem.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an SLA device for forming high-viscosity slurry, and also relates to a control method for forming slurry. Background technique [0002] Stereo Lithography Apparatus (SLA) is the first rapid prototyping technology proposed and applied in commerce. SLA works based on the principle of photopolymerization of photosensitive resin. The computer controls the ultraviolet laser to scan the photosensitive resin, and the photosensitive resin in the scanning area is cured and gradually accumulated until the required parts are formed. Due to its low cost and high precision of the prepared parts, the scope of use of the SLA process has expanded from simple resin forming to the forming of ceramics, metals and other materials, as well as the forming of mixed resin materials such as ceramic slurry. Ceramic slurry is a mixture of resin and ceramic powder. Its performance is better...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide SLA equipment for forming high-viscosity slurry, which solves the problems in the prior art that the high-viscosity mixed resin material is easy to stick to the paving scraper, and the uncured high-viscosity mixed resin material on the forming platform is difficult to clean up in time , causing the problem of material contamination
