Chinese researchers have developed the worlds first-ever 2D printing for ceramics that are mechanically robust and can have complex shapes, offering broad potential applications in telecommunications, electronics and even space exploration.中国研究工作人员早就产品研发出世界上首项2D陶瓷打印机技术性,此项技术性使陶瓷特性坚固且形状简易,在电信网、电子器件乃至外太空探索行业中具备广泛的运用于发展潜力。Researchers at City University of Hong Kong reported in a study published last Friday in the journal Science Advances a novel ceramic ink, a mixture of polymers and ceramic nanoparticles.香港城市大学的科学研究工作人员在上周五公布发布在《科学进展》杂志期刊上的一项科学研究中报道了一种精美的“陶瓷油墨”,它是一种高聚物和陶瓷纳米颗粒的化合物。The 三维-printed ceramic precursors printed with this novel ink are soft and can be stretched three times beyond their initial length, according to the study.该研究表明,用这类新式油墨打印机的三维打印机陶瓷前体很硬实,而且能够裁切高达其原始长短的三倍。

These flexible and stretchable ceramic precursors allow complex shapes, such as origami folding. With proper heat treatment, ceramics with complex shapes can be made, making them the 2D ceramics.这种绵软且可裁切的陶瓷前体可变换简易的形状,比如手工折纸款式。根据必需的热处理工艺,能够生产制造出有形状简易的陶瓷,使其沦落2D陶瓷。2D printing is conventional 三维 printing combined with the additional element of time as the fourth dimension, where the printed objects can re-shape or self-assemble themselves over time with external stimuli, such as mechanical force, temperature, or a magnetic field.2D打印机是传统式的三维打印机与第四维度可选原素時间的集合体。

在其中打印机物件能够伴随着时间的流逝,在外部经济刺激性下(比如机械设备力,溫度或电磁场)重构或自组。The existing 三维-printed ceramic precursors, which are usually difficult to deform, also hinder the 2D printing of ceramics with complex shapes.目前的三维打印机陶瓷前体一般来说没法形变,也阻拦了具备简易形状的陶瓷的2D打印机。The researchers led by Lv Jian, chair professor of mechanical engineering, made use of the elastic energy stored in the stretched precursors for shape morphing.机械自动化院主任吕坚带领科学研究工作人员运用存储在裁切前体中的延展性动能来变化陶瓷的形状。

When the stretched ceramic precursors are released, they undergo self-reshaping and after heat treatment, the precursors turn into ceramics.当裁切的陶瓷前体被出狱时,他们不容易历经自主重构而且在热处理工艺以后,前体会变成陶瓷。The resultant elastomer-derived ceramics are mechanically robust. They can have a high compressive strength-to-density ratio and can come in large sizes with high strength compared to other printed ceramics.得到 的聚氨酯弹性体继承的陶瓷具备坚固的物理性能。他们具备很高的抗压抗压强度与相对密度比,而且与别的打印机陶瓷相比能够具备非常大的抗压强度规格。

With the versatile shape-morphing capability of the printed ceramic precursors, its application can be huge, said Lv.吕坚答复,2D打印机陶瓷前体的多形状形变工作能力促使其运用于范畴将十分广泛。
