Light-cured 3D printing material supply fluid path system

Abstract

The invention discloses a light-cured 3D printing material supply fluid path system. The system comprises a host material box, a first filter, a fluid conveying pipeline, a fluid pump, a solenoid valve, a second filter, an auxiliary material box, a flexible tube, a fluid level sensor and a negative pressure device, the host material box is arranged above the shell of a printer, the auxiliary material box is arranged on the printing head of the printer, the auxiliary material box is connected with the printing head through the flexible tube, the fluid level sensor is arranged in the auxiliary material box, the negative pressure device is arranged at the top of the auxiliary material box, one end of the fluid conveying pipeline stretches into the host material box, the other end of the fluid conveying pipeline is connected with the auxiliary material box body, the first filter, the fluid pump, the solenoid valve and the second filter are sequentially arranged on the fluid conveying pipeline, the first filter is arranged on the fluid conveying pipeline in the host material box, and the second filter is arranged on the fluid conveying pipeline close to the auxiliary material box. The light-cured 3D printing material supply fluid path system shortens a distance from a printing material to the printing head, guarantees timely supply of the printing material, reduces the load of a printing system and improves the printing efficiency.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a light-curing 3D printing material supply liquid circuit system. Background technique [0002] With the globalization of the economy, the market competition is becoming more and more fierce. Whether the product can quickly affect the market is the key to the success or failure of the company's competition. This requires companies to shorten the research and development cycle of new products. There will be an increasing demand for rapid prototyping equipment that reduces product development time and development costs by shortening the product design feedback cycle, improving the success rate of new product development, and reducing product development time and development costs. In contrast, 3D printing rapid prototyping technology has obvious advantages in terms of molding speed, types of moldable materials, equipment prices, operation and maintenance costs, and ...

AI Technical Summary

Problems solved by technology

Light-curing 3D printing is a rapid prototyping technology based on the layer-by-layer accumulation and curing of sprayed droplets. It is required that the printed material can produce stable and controllable droplets through the sprayed print head. It is supplemented by sucking the material from the flow channel by the capillary action of the liquid. In order to ensure that the material in the print head can be replenished in a timely and stable manner, the connection between the material and the print head is required to be as short as possible, preferably Fixing the material cartridge directly on the print head system so that the material cartridge moves with the print head system is impractical and difficult to achieve for large-capacity material cartridges that move together with the print head
