Abstract

A laser 3D printer capable of finishing high-precision sand mold manufacture at one step comprises a printing device, a feeding device, a material distribution device and a drying device, wherein the printing device comprises a base, a lifting device is arranged on the base for controlling the rise and fall of a lifting platform, a sand paving platform is arranged on the lifting platform, and a laser printing head is arranged above the sand paving platform; the feeding device comprises a sand box and a feeding pipeline; the material distribution device comprises a hopper and a sand pushing plate, the hopper is located at the bottom end of the feeding pipeline and used for distributing sand provided by the feeding device on the sand paving platform, and the sand pushing plate is used for uniformly pushing the sand flat; the laser printing head is used for printing patterns on a sand surface; and the drying device is used for drying a printed sand mold. The laser 3D printer can effectively increase molding speed and efficiency and can strictly control printing sizes, so that the size precision of molded components is high. By adopting the printer, sand molds with various sizes and complicated curvy surfaces can be printed, and the range of applications is wide.

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 (StereoLithography) and so on. [0004] Thin material selective cutting LOM (Laminating Object Manufacturing), mainly uses thin film as material, la...
