Novel 3D printer

Abstract

The invention discloses a novel 3D printer. The novel 3D printer has a good sealing effect. When it is necessary to clean a sealing cavity inside the 3D printer, there is no need to open a sealing door of the 3D printer, and the inside of the sealing cavity can be cleaned directly by manually using sealing gloves. In this way, the sealing cavity does not communicate with the outside so that the sealing cavity can be prevented from being polluted by the external environment. In addition, a connecting rod of a scraper is connected with a sealing belt, so that the scraper and the sealing belt synchronously move in a slide groove; and the sealing belt can seal the slide groove, so that printing powder in the sealing cavity is unlikely to leak out of the sealing cavity, the printing quality ofproducts can be effectively guaranteed, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a novel 3D printer. Background technique [0002] With the development of 3D printing technology, 3D printers have been able to directly manufacture metal parts with metallurgical bonding, compact structure, good dimensional accuracy and mechanical properties, which has broad application prospects and has become a research hotspot in the field of additive manufacturing today. 3D printer printing metal parts has the advantages of personalized design, fast forming, and short manufacturing cycle. It is very suitable for the manufacture of small batches, personalized metal parts with complex surfaces and internal structures. [0003] Generally speaking, 3D printers on the market perform printing operations in their sealed chambers. However, the sealing performance of 3D printers on the market is relatively poor. On the one hand, when the sealed chamber needs to be cleaned, the se...

Problems solved by technology

[0003] Generally speaking, 3D printers on the market perform printing operations in their sealed chambers. However, the 3D printers on the market have relatively poor airtightness. On the one hand, when the sealed chamber needs to be cleaned, the sealed door needs to be opened. Operation, and this operation is easy to make the sealed cavity easily polluted by the external environment. On the other hand, the printing powder in the sealed cavity is easy to leak out from the sealed cavity to affect the normal use of the device, thereby seriously affecting the printing quality of the product.
