3D打印技术可以直接从计算机辅助数字设计中生产复杂的物体。该技术传统上被大公司用于在生产前生产合适的概念原型（“快速原型”）。然而，近年来，人们开始采用该技术作为全面的制造解决方案。RepRap和Fab@Home等低成本桌面3D打印机的出现意味着更广泛的用户群现在能够访问桌面制造平台，使他们能够生产高度定制的个人使用和销售产品。这种使用的增加已经与对能够打印功能元件（例如电子传感器）的打印技术和材料的需求相结合。在这里，我们提出了一种简单的导电热塑性复合材料的配方，我们称之为“carbomorph”，并演示了它如何用于未经修改的低成本3D打印机，以打印能够感测机械弯曲和电容变化的电子传感器。我们展示了这种能力如何可以用来生产定制的传感设备和用户界面设备沿着与嵌入式传感能力的印刷对象。低成本3D打印的这一进步为3D打印领域提供了一个新的范例，在单个构建过程中将打印传感器和电子器件嵌入3D打印物体中，而不需要包含碳纳米管等添加剂的复杂或昂贵的材料。
3D printing technology can produce complex objects directly from computer aided digital designs. The technology has traditionally been used by large companies to produce fit and form concept prototypes (‘rapid prototyping’) before production. In recent years however there has been a move to adopt the technology as full-scale manufacturing solution. The advent of low-cost, desktop 3D printers such as the RepRap and Fab@Home has meant a wider user base are now able to have access to desktop manufacturing platforms enabling them to produce highly customised products for personal use and sale. This uptake in usage has been coupled with a demand for printing technology and materials able to print functional elements such as electronic sensors. Here we present formulation of a simple conductive thermoplastic composite we term ‘carbomorph’ and demonstrate how it can be used in an unmodified low-cost 3D printer to print electronic sensors able to sense mechanical flexing and capacitance changes. We show how this capability can be used to produce custom sensing devices and user interface devices along with printed objects with embedded sensing capability. This advance in low-cost 3D printing with offer a new paradigm in the 3D printing field with printed sensors and electronics embedded inside 3D printed objects in a single build process without requiring complex or expensive materials incorporating additives such as carbon nanotubes.
