Printing module of rapid prototyping device

Abstract

The present invention relates to a printing module of a rapid prototyping device, which includes a printing platform, a bearing seat and at least two identical modular liquid spray boxes, and the at least two identical modular liquid spray boxes are arranged on the bearing seat , wherein the liquid spraying box has a box body and a liquid spraying chip, the liquid spraying chip has a length and a width to form a total area area, the total area area includes: a non-wiring area, at least three liquid supply tanks are arranged, and they are arranged parallel to each other , which are respectively connected to a liquid storage chamber in the box body of the liquid spray box; the wiring area is provided with a liquid spray control circuit, and the liquid spray control circuit circuit includes a plurality of droplet generators, and each droplet generator is composed of a heating resistor and a driving transistor. and the liquid spray hole, the liquid spray control circuit receives the power signal, the print data signal, the preheating data signal, the preheating control signal, the reverse preheating control signal, the heating control signal, the reverse heating control signal and is connected to the common terminal connection to control the droplet generator.

Description

technical field [0001] The invention relates to a printing module of a rapid prototyping device. Background technique [0002] Rapid prototyping technology (RP technology for short) is developed based on the concept of building a pyramid-like layer stacking molding. Automatically and quickly convert the design scheme of any complex shape into a 3D solid model, which greatly shortens the 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. Molding technology provides a more complete and convenient product design communication tool for technical personnel, as well as between technical personnel and enterprise decision makers, product users and other non-technical personnel, thus significantly improving the competitiveness and competitiveness of products in the market. The ability of enterprises to respond quickly to the market. [0003]...

Problems solved by technology

[0006] However, when the rapid prototyping jet printing operation of this 3D object is implemented, in addition to containing black and color inks, the printing ink cartridge 12 needs to contain an additional high-viscosity adhesive to bond the construction materials, and then can be layered. Layers are stacked to form 3D objects. Therefore, traditional rapid prototyping devices need to be equipped with additional carriers and printing ink cartridges to accommodate high-viscosity adhesives. In this way, the overall volume of the printing module 1 will increase. , while increasing the cost of the carrier and print cartridges
