3D printing device

Abstract

The invention discloses a 3D printing device. The 3D printing device comprises an outer barrel box, wherein an inner barrel box is fixedly installed on the upper portion inside the outer barrel box, vertical remaining grooves are formed in the outer surfaces of a barrel body on the periphery of the inner barrel box, fans are arranged inside the remaining grooves, fan boxes of the fans correspond to the remaining grooves in size, a plurality of through holes are formed at the position, corresponding to the remaining grooves, of the upper portion of the inner surface of the inner barrel box at intervals, connecting rods are fixedly connected to the middles of the outer surfaces of the lower ends of the fan boxes of the fans, a motor is arranged at the bottom inside the outer barrel box, the output end of the motor is fixedly connected with a circular corrugated guide rail, and the ends, away from the fans, of the connecting rods extend into a rail groove of the circular corrugated guide rail. In the using process of the device, surface roughening of a model is prevented, the smooth degree of the surface of the model is guaranteed, the texture of the formed model is further guaranteed, cooling of the model is facilitated, solidification of the model is accelerated, and then application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of 3D forming, in particular to a 3D printing device. Background technique [0002] 3D printing belongs to a kind of rapid prototyping technology. It is a technology based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by stacking and accumulating layer by layer. In the past, it was often used in Mold manufacturing, industrial design and other fields are used to make models, and are now being gradually used in the direct manufacture of some products, especially some high-value applications have already used this technology to print parts, which means that 3D printing is a technology At present, the resolution of 3D printers is sufficient for most applications. Some technologies also use supports during the printing process. For example, when printing some upside-down objects, some easy-to-remove Things (such as soluble things) are used as supports. ...

[0002] 3D printing belongs to a kind of rapid prototyping technology. It is a technology based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by stacking and accumulating layer by layer. In the past, it was often used in Mold manufacturing, industrial design and other fields are used to make models, and are now being gradually used in the direct manufacture of some products, especially some high-value applications have already used this technology to print parts, which means that 3D printing is a technology At present, the resolution of 3D printers is sufficient for most applications. Some technologies also use supports during the printing process. For example, when printing some upside-down objects, some easy-to-remove Things (such as soluble things) are used as supports. In the process of 3D printing, powder and fine materials are easy to be adsorbed by the model in the printing process. The surface of the model that absorbs powder and fine materials is rough, which affects the model The degree of smoothness will affect the texture of the model, which in turn will affect the printing effect
