Small part 3D printer

Abstract

The invention provides a small part 3D printer. The small part 3D printer comprises a case, a printing table is installed inside the case, a sound collecting plate is installed at the bottom of an inner cavity of the case, fixing blocks are installed at the bottom of the printing table, a vibration rod is fixedly connected with the bottom of each fixing block, and the end, away from the fixing block, of each vibration rod is sleeved with an outer sleeve; and a damping spring is arranged inside each outer sleeve. According to the small part 3D printer, a sound adsorption plate is arranged, noise of the printer is adsorbed into a sound adsorption sponge through sound adsorption holes, the density of the sound adsorption sponge is adjusted through sound adsorption springs, the noise is buffered, and harm of the noise to the human body is reduced; and the arranged outer sleeves, the damping springs and the vibration rods are used in a cooperative mode, vibration generated in the operationprocess of the printer can be effectively adsorbed by extruding and damping the damping springs through the vibration rods, the strength of vibration generated by the printer and transmitted to the ground is reduced, and noise generated by operation of the printer is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer for small parts. Background technique [0002] 3D printer, a machine of rapid prototyping technology, is a technology based on a digital model file, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and it is gradually being used in the direct manufacture of some products, which means that this technology is becoming popular. In current 3D printers, the body vibrates when the printing head is moving, which is prone to noise, making the working environment too noisy. In such an environment, the ears of long-term workers will be damaged, affecting hearing health. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present inventio...

AI Technical Summary

Problems solved by technology

For current 3D printers, the body vibrates when the printing head is moving, which is prone to noise, which makes the working environment too noisy. In this environment, the ears of long-term workers will be damaged, which will affect hearing health.
