AI Technical Summary

Technical Problem

The resin tank size design of traditional 3D printers leads to significant material waste when printing small objects, reduced material freshness, and impacted print quality. Furthermore, high-viscosity resins are difficult to fully cure on large-scale build platforms, resulting in print failures.

Method used

Using hydraulic devices and fluid mechanics principles, the transfer and curing of printing materials are controlled by the movement of a piston within the chamber. Flexible films or coatings are used to optimize the printing process, enabling precise use of materials and effective curing of high-viscosity resins.

Benefits of technology

It reduces material waste, improves printing quality and efficiency, ensures the full curing of high-viscosity resin, and adapts to the need for rapid switching between different printing materials.

Abstract

This invention relates to a system and method for printing 3D objects using a hydraulic device. The device can include cartridges or container assemblies that can be single-use or disposable. The container assembly can integrally house structures such as pistons, platforms, multiple chambers, and channels, wherein the channels and chambers are fluidly connected and configured to hold sufficient 3D printing material suitable for printing a single 3D object. In an exemplary embodiment, a moving piston transfers 3D printing material from one chamber to another where the platform is located; radiation from a light engine coupled to a chamber including the platform exposes the 3D printing material to curing light on the platform surface or to a cured layer of printing material on the platform, thereby constructing a 3D object on the platform.
