a 3d printer

Abstract

The invention discloses a novel 3D printer comprising a base and a printing device arranged above the top of the base; the top of the left side of the base is provided with a supporting post; first slip grooves are formed in the top of the left side of the base in a back and forth symmetry way; a second slip groove is formed in the middle end of the inner bottom of each of the first slip grooves; the second slip grooves are internally provided with first screw rods extending left and right; the first slip grooves are internally connected with first slip blocks in a slip fit way; the printing device is internally provided with a slip cavity; a convex end is arranged inside the right side of the slip cavity and is internally provided with a locking cavity extending rightwards; a printing driving device is fixedly arranged in the bottom of the printing device; the bottom of the printing driving device is matched and connected with a printing head; a through groove is formed between the top of the printing driving device and the bottom of the locking cavity; and a rotating rod vertically extending is matched with and connected to the inside of the through groove. The novel 3D printer is simple in structure, high in safety and capable of increasing the printing efficiency and improving the printing precision.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a machine of rapid prototyping technology. It is based on digital model files, using special wax or plastic and other adhesive materials to manufacture three-dimensional objects by printing layers of adhesive materials. object. 3D printing can directly generate objects of any shape from computer graphics data without machinery or molds, thus greatly shortening the production cycle of products and improving productivity. At present, some 3D printers on the market adopt the technology of "fusion deposition molding". The whole process is to melt the plastic in the printing part, and then form a thin layer by depositing plastic fibers. The problem of easy displacement seriously affects normal printing. In addition, the existing 3D printers cannot realize immediate stop during th...

Problems solved by technology

At present, some 3D printers on the market adopt the technology of "fusion deposition molding". The whole process is to melt the plastic in the printing part, and then form a thin layer by depositing plastic fibers. The problem of easy displacement seriously affects normal printing

In addition, the existing 3D printers cannot stop immediately during the printing process of the printing head rotation, which does not meet the existing needs
