    • A one piece eyewear having concealed hinges made via 3D printing is disclosed. More specifically, the invention includes a U-shaped hinge with irregular offsets that are blended parametric curves that connect a lens frame to temple bars. The hinge is most flexible at its parabolic cross section and allows the temple bars to open and close, mimicking the rotational and stress bearing properties of traditional mechanical hinges. The eyewear is sculpted in a 3D modeling program that exports digital instructions for rendering the hinges, lens frame, and temple bars as a single construct by a 3D printer. The one piece eyewear is capable of accepting prescription or non-prescription lenses. A method for making the eyewear having concealed hinges is also disclosed.
    • 公开了具有通过3D打印制成的隐藏铰链的单件式眼镜。 更具体地说,本发明包括具有不规则偏移的U形铰链,该U形铰链是将透镜框架连接到镜腿的混合参数曲线。 铰链在其抛物线横截面上最为灵活,并允许太阳镜杆打开和关闭,模仿传统机械铰链的旋转和应力承载特性。 该眼镜是在3D建模程序中雕刻的,该程序导出数字指令,以便通过3D打印机将铰链,镜框和镜腿呈现为单个结构。 一件式眼镜能够接受处方或非处方镜片。 还公开了一种制造具有隐藏铰链的眼镜的方法。
