Device for preparing additive manufacturing material

Abstract

The invention relates to a device for preparing an additive manufacturing material. The device for preparing the additive manufacturing material comprises a furnace body, the furnace body is divided into left and right spaces by a heat conducting plate, wherein one space is a heating chamber, and the other space is a containing chamber used for storing metal particles; the upper side of the containing chamber is connected with a storing chamber used for storing other metal particles, and a cavity is formed in the chamber wall of the storing chamber; the heating chamber supplies heat to the containing chamber from the side part and the bottom part of the containing chamber, and residual heat generated by melting of the metal particles of the containing chamber is supplied to the storing chamber through the bottom part of the storing chamber and the cavity. According to the device for preparing the additive manufacturing material, different metal particles can be separately stored by adopting the containing chamber and the storing chamber, and the metal particles inside the containing chamber are uniformly heated by simultaneously supplying heat to the side part and the bottom part of the containing chamber; and meanwhile, the residual heat generated by the containing chamber is used for heating the metal particles in the storing chamber, thus the heating requirements of different metal particles can be met, on the one hand, preparation quality of a material can be improved, on the other hand, energy can be saved, and the production cost can be lowered.

Description

technical field [0001] The invention relates to a preparation device for additively manufactured materials. Background technique [0002] Additive manufacturing technology is a kind of rapid prototyping technology. It is based on digital model files, through software layered discrete and numerical control molding system, using laser beams, hot melt nozzles, etc. to build up bondable materials such as powdered metal or plastic, and superimpose them layer by layer. The core principle of the technology for manufacturing physical products is "layer-by-layer manufacturing, layer-by-layer superposition". Compared with the traditional "subtractive manufacturing" manufacturing technology, it has the ability to realize integrated manufacturing of complex-shaped workpieces, greatly shorten the product production cycle, and save a lot of energy. Material, improve production efficiency and other obvious advantages. The existing equipment for the preparation of additive manufacturing m...
