AI Technical Summary

Technical Problem

Existing UV-curing printers can only use a single printing method, which cannot meet different printing needs, resulting in an irreconcilable contradiction between consumable usage and printing costs.

Method used

A large-format dual-mode photopolymer printer was designed, which includes pull-up and sink-down printing modules. The two printing modes are switched through a flipping mechanism, and seamless stitching is achieved by using an image stitching method.

Benefits of technology

It enables seamless switching between different printing modes on the same printer, reducing printing costs and improving printing accuracy and success rate, adapting to various printing needs.

Abstract

本发明涉及一种大幅面双模式光固化打印机及图像拼接方法，其中的打印主体能够相对翻转机构翻转，实现两种打印模式的切换，一个打印主体适配两种打印模式，使得打印机的应用场景更广，当需要打印精准度较低的模型时，可使用上拉式打印模式，降低打印成本，当需要打印精准度较高的模型时，可使用下沉式打印模式，提高打印精度和成功率。光固化打印机不论选择上拉式打印模式还是下沉式打印模式，均能够对超出设定范围的投影图片进行拼接打印，对图像进行分割成若干个幅图像块，在同一层相邻两幅图像块的结合部位，以单像素为单位设置重叠区域，选择需两次光固化的像素点，进行固化，实现相邻两幅图像块的无缝拼接，提高大幅图像的打印质量。
