Once the operational life of electronics component is over, it becomes part of electronic waste (e-waste). Afterwards, it is either dumped in landfills or recycled for metallic constituents. Landfills, in long run, are proven hazardous. Recycling approach also leaves a significant energy footprint on environment. This article presents a brief insight into the harmful impacts of the e-waste. Primary aim of this work is to justify the importance of adjusting new technology according to the conventional one so that the working components from the obsolete technology can be utilized optimally. Prototype of compact 3D printer and 3D scanner combo is presented here, as one of the solution. The main components of this system, namely stepper motors, power supply, and metallic supporting structure, are salvaged from e-waste. Interfacing and control codes (novel aspects of the work) are developed for automation. Performance of this printer is compared with a commercial 3D printer. Prototype is found suitable (even performing at par) for samples (wall thickness of \(0.1mm\)). The inter-convertibility act will become necessary when new technologies like 5G, electric vehicle take over and existing one will become obsolete leaving significant e-waste to dispose. It is expected that this philosophy, if integrated at industrial level by encouraging protocols for product development and manpower training, would reduce the burden on the environment.

电子元件的使用寿命一旦结束，便成为电子废物（电子废物）的一部分。之后，将其倾倒在垃圾填埋场中或回收用作金属成分。从长远来看，垃圾填埋场被证明是危险的。回收方法还给环境留下了巨大的能源足迹。本文简要介绍了电子垃圾的有害影响。这项工作的主要目的是证明根据常规技术调整新技术的重要性，以便可以最佳地利用过时技术中的工作组件。作为解决方案之一，此处介绍了紧凑型3D打印机和3D扫描仪组合的原型。该系统的主要组件，即步进电机，电源和金属支撑结构，均已从电子垃圾中清除。接口和控制代码（工作的新方面）是为自动化而开发的。将该打印机的性能与商用3D打印机进行了比较。发现原型适用于样品（甚至与标准品性能相同）\（0.1mm \））。当5G，电动汽车等新技术被接管，而现有技术已过时，留下大量电子废物进行处理时，将需要相互转换法案。可以预期，如果通过鼓励产品开发和人力培训协议将这种理念整合到工业级别，将会减轻环境负担。
