Stereoscopic moulding device

Abstract

The invention relates to a stereoscopic moulding device, used for moulding a stereoscopic article. The stereoscopic moulding device at least comprises a dismountable construction tank, a movable powder supply tank, a printing assembly, a heating assembly, a lifting device, a spray nozzle cleaning device, a spray nozzle sealing device and a jet-printing moulding and powder spreading isolated operation device; wherein the movable powder supply tank can move above the dismountable construction tank to supply construction powder, so as to feed powder; the printing assembly is arranged below the dismountable construction tank; the spray nozzle sealing device comprises a bearing seat, at least one sealing part and a moisturizing device; the jet-printing moulding powder spreading isolated operation device comprises a telescopic dust boot which is connected with one side of the powder supply tank, so as to cover and be linked with the construction powder in the construction tank when the powder supply tank moves.

Description

technical field [0001] The invention relates to a three-dimensional forming device, in particular to a desktop three-dimensional forming device. Background technique [0002] Rapid prototyping technology (RP technology for short) is developed based on the concept of building a pyramid layer by layer. Its main technical feature is the rapidity of forming, and it can be molded without any tools, molds and fixtures. Automatically and quickly convert the design scheme of any complex shape into a 3D solid model, which greatly shortens the research and development cycle of new products and reduces the cost of research and development, and can ensure the time to market of new products and the first-time success rate of new product development. It provides a more complete and convenient product design communication tool between technical personnel and non-technical personnel such as enterprise decision makers and product users, thus significantly improving the competitiveness of pro...

Problems solved by technology

[0007] Another object of the present invention is to provide a three-dimensional forming device to solve the problem that the traditional three-dimensional forming device cannot thoroughly clean the nozzle, and the nozzle is dry and blocked due to lack of moisture when the nozzle is sealed, resulting in damage to the nozzle and reducing the use of the nozzle lifespan, and cause poor functionality of subsequent printing, unable to continue printing to produce high-quality 3D products and other shortcomings

[0008] Another object of the present invention is to provide a three-dimensional molding device with a detachable construction tank, so as to solve the problem that the existing technology is prone to pollute the working environment due to powder flying when taking finished products, and high-frequency cleaning is required to maintain normal operating disadvantages
