Problems solved by technology

Although these technologies are mature, each has some problems. For example, the photocuring process is expensive, requires support, resin shrinkage leads to a decrease in precision, and the photocuring resin has certain toxicity problems; the material properties of the layered entity manufacturing process Poor, high cost compared with non-laser technology, lower precision than photocuring process, and complicated equipment; the disadvantage of 3D printing process is that the strength of formed parts is low, and it can only be used for conceptual use, not for functional experiments

Abstract

The invention provides a magnetic-control sinter molding device and method. The device comprises a trough structure for containing powder, and a magnetic ball making contact with the powder and sintering the powder. An electromagnetic heater for heating the magnetic ball is arranged outside the trough structure. Electromagnets used for controlling the magnetic ball to move are mounted outside the trough structure. In addition, the invention provides the corresponding magnetic-control sinter molding method. The magnetic-control sinter molding device is simple, low in cost and capable of achieving the purpose of rapid molding without causing environment pollution in the whole sinter molding process.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping, in particular to a magnetron sintering forming device and method. Background technique [0002] At present, the rapid prototyping process mainly includes the following types: 1) Photocuring process: using laser light to continuously irradiate light-cured liquid resin to solidify it; 2) Layered solid manufacturing process: it uses laser cutting foil, and the foil between The hot melt adhesive is melted and bonded under the pressure and heat transfer of the hot pressing roller, and the prototype is manufactured layer by layer; 3) Selective laser sintering process: the laser is used to sinter the powder material point by point, so that the powder material wrapped in the powder material The solid binder or the powder material itself is melted to realize the bonding of the material; 4) 3D printing process: the prototype is made by spraying the binder point by point to bond the powder materia...
