Abstract

The invention discloses a separable selective melting and sintering rapid forming device. The device mainly comprises a high-energy-beam generator set, a scanning system, a protection cavity, a cavity support, a forming machine tool, an atmosphere protection system and a control system, wherein the protection cavity, the forming machine tool and the cavity support are core assemblies of the device. The forming machine tool or the protection cavity is designed to be movable or rotatable, and the forming machine tool and the protection cavity can separate from each other; parts with any size and any shape can be manufactured without changing the forming precision or the complexity of the parts or the mechanical performance and can be conveniently taken out of the forming machine tool, and the operating efficiency is doubled. The device is particularly suitable for manufacturing parts with any complex shape, which are large or extra large or extra large in size in a certain direction.

Description

technical field [0001] The invention belongs to the field of rapid prototyping, and specifically relates to a separate selective melting and sintering rapid prototyping equipment. The formed parts can be metal, non-metal or composite materials of metal and non-metal. Background technique [0002] Additive Manufacturing technology (Additive Manufacturing), also known as 3D printing technology, is a new manufacturing technology based on the principle of layer-by-layer accumulation of discrete materials, based on the three-dimensional CAD model of the product, and the product prototype or parts are accumulated layer by layer through materials. [0003] The selective melting and sintering rapid prototyping technology based on powder coating can manufacture parts of almost any shape because it can use auxiliary structures and loose powder as support, and has attracted the most attention among many additive manufacturing technologies. Its basic working principle is to spread a cer...
