Abstract

A laser 3D printer that completes high-precision sand molding at one time, including a printing device, a feeding device, a material distribution device, and a drying device. The printing device includes a base, and a lifting device is installed on the base to control the lifting of the lifting platform. There is a laser printing head above the sand laying platform, the feeding device includes a sand box and a feeding pipe, the distributing device includes a hopper and a sand pushing plate, the hopper is located at the end of the feeding pipe, and is used Arranged on the sand laying platform, the sand pushing plate is used to push the sand evenly, the laser printing head is used to print patterns on the sand surface, and the drying device is used to dry the printed sand mold. The laser 3D printer of the invention can effectively improve the molding speed and efficiency, and the printing size can be strictly controlled, so that the dimensional accuracy of the molded parts is high. The printer of the invention can print sand molds of various sizes and complex curved surfaces, and has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a laser 3D printer capable of producing high-precision sand molds at one time. Background technique [0002] Laser rapid prototyping technology can quickly convert the computer-aided design model (CAD model) of product parts into physical models, part prototypes or parts. Laser rapid prototyping is directly driven by the CAD model, and the corresponding physical entity can be obtained only by changing the CAD model, which greatly shortens the production cycle from conceptual model design to production of products or samples. [0003] The current laser rapid prototyping methods mainly include: selective cutting of thin materials LOM (Laminating Object Manufacturing), selective laser sintering SLS (Selected Laser Sintering) and SL (Stereo Lithography). [0004] Thin material selective cutting LOM (Laminating Object Manufacturing), mainly uses thin film as material, laser cuts ...
