AI Technical Summary

Technical Problem

Existing 3D printing equipment faces problems such as low printing accuracy, slow printing speed and unstable bonding between layers when dealing with high viscosity magnetic resins.

Method used

A photocuring 3D printer for processing magnetic resins is designed, equipped with a magnetic scraper coating mechanism. The scraper body evenly scrapes the resin through movement, and creates a uniform magnetic field through the built-in permanent magnet to guide the alignment of the magnetic particles in the resin.

Benefits of technology

Through the magnetic scraper coating mechanism, the leveling problem of high viscosity magnetic resin and the alignment problem of magnetization direction are solved, the printing speed and accuracy are improved, and the interlayer adhesion force is enhanced.

Abstract

The invention discloses a photocuring 3D printer for processing magnetic resin, and belongs to the technical field of 3D printing, the photocuring 3D printer comprises a material disc, one side of the top of the material disc is provided with a magnetic scraper coating mechanism, the magnetic scraper coating mechanism comprises a driving part in transmission connection with the material disc, the driving part is in transmission connection with a hollow scraper main body, and the scraper main body is located in the material disc; a plurality of sets of permanent magnets are arranged in the scraper body at equal intervals, a release film assembly is arranged in the material disc, digital light processing equipment is arranged below the material disc, and a forming assembly is arranged on the side, away from the driving part, of the upper portion of the material disc. The leveling problem and the alignment problem of the magnetization direction of the high-viscosity magnetic resin in the printing process are solved by arranging the magnetic scraper coating mechanism; the scraper main body uniformly scrapes the resin through movement, so that the waiting time of automatic leveling is saved, and the printing speed is greatly improved; meanwhile, the height of the scraper body can be adjusted, so that the thickness of the resin layer can be accurately controlled.
