Novel selective laser sintering (SLS) printing product clearing device

Abstract

The invention discloses a novel selective laser sintering (SLS) printing product clearing device. The novel SLS printing product clearing device comprises a box body, a box door, an exhaust pump, a powder suction gun and a powder storage box; one side of the box door is arranged on the box body in a hinged mode, the box door is provided with at least two operating ports, each operating port is connected with operation gloves, and the operating ports are further provided with observation windows; the powder storage box and the exhaust pump are fixed to the outer side face of the box body correspondingly, and the powder storage box and the exhaust pump communicate through a connecting pipe; and an exhaust pipe on the exhaust pump extends into the box body and is divided into two air ducts, one air duct is connected with the powder suction gun, and the other air duct directly leads to the interior of the box body. The novel SLS printing product clearing device solves the problem that in the prior art, after printing is finished by an SLS-type 3D printer, in the clearing process, raw material powder is prone to diffusing in the air and pollutes the environment and also generates threatto physical and mental health of staff.

Description

technical field [0001] The invention relates to the field of SLS printers, in particular to a novel SLS printing product cleaning device. Background technique [0002] Selective laser sintering (SLS for short) is a widely used rapid prototyping technology. It uses solid powder materials as raw materials, and uses laser to scan the cross-section of a three-dimensional solid layer by layer to complete prototype manufacturing. It is not limited by the complexity of the part shape. , does not require any tooling and molds, and has a wide range of applications. SLS rapid prototyping technology can be used to print out 3D models. Therefore, there is a type of 3D printer on the market called SLS 3D printers, which can quickly print out simple 3D models. [0003] However, after the SLS type 3D printer in the prior art finishes printing, during the cleaning process, the raw material powder is easy to diffuse in the air, pollutes the environment, and also threatens the physical and m...

AI Technical Summary

Problems solved by technology

[0005] In view of the above technical problems, the purpose of the present invention is to overcome the problem that raw material powder is easily diffused in the air during the cleaning process after the SLS type 3D printer in the prior art finishes printing, pollutes the environment, and also poses a threat to the physical and mental health of the staff. In order to provide a new type of SLS printing product that can effectively prevent the raw material powder from being diffused in the air when cleaning the printed product in the forming box during use, and can quickly recycle the raw material powder in the cleaning environment cleaning device
