Problems solved by technology

[0002] The powder bed in traditional 3D printing is a metal plate plus a scraper. After printing a layer of metal powder, use a scraper to spread a layer of metal powder. This process mainly relies on the gravity of the powder itself and the fluidity of the powder for filling. The powder The tap density is not high, which can cause defects such as holes or voids in the print

Abstract

The invention discloses an ultrasonic oscillating powder bed system capable of significantly increasing the tap density of powder, thereby greatly reducing the number of defects such as holes or voids in printed parts, and improving the comprehensive performance of printed parts. The ultrasonic oscillating powder bed system includes an installation base plate, the installation base plate is provided with an installation housing; the installation housing is provided with a second guide rail, a second slide rail, a second slider, a scraper, an ultrasonic emitting head, a first Two ultrasonic emitters, first guide rail, first slider, 3D printing nozzle, raw material inlet pipe, first slide rail, cover plate, 3D printing raw material inlet pipe, atmosphere pipeline joint, metal powder feeder, telescopic device; A transparent observation window is arranged on the installation shell. The ultrasonic oscillating powder bed system can improve the quality of 3D printed parts and reduce the failure rate of 3D printed parts.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an ultrasonic oscillating powder bed system. Background technique [0002] The powder bed in traditional 3D printing is a metal plate plus a scraper. After printing a layer of metal powder, use a scraper to spread a layer of metal powder. This process mainly relies on the gravity of the powder itself and the fluidity of the powder for filling. The powder The tap density is not high, which can cause defects such as holes or voids in the print. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultrasonic oscillating powder bed system that can significantly increase the tap density of powder, thereby greatly reducing the number of defects such as holes or voids in printed parts, and improving the comprehensive performance of printed parts. [0004] The technical solution adopted by the present invention to solve th...
