The world has been hit hardest by a type of Severe Acute Respiratory Syndrome (SARS) virus called corona. This vulnerability did not leave all the superpowers in the world. The virus, is spread through coughs and sneezes. It is also spread by touching objects or parts of an infected person. For this reason, it is considered an infectious disease. It is very difficult to protect ourselves from such a contagious disease. But the World Health Organization (WHO) says there are certain guidelines to follow. The first way is to prevent the spread of COVID-19 social infection by adhering to social spaces (i.e. 2 m intervals). Second, we can protect ourselves by using appropriate safety equipment. We can also protect ourselves from the COVID-19 virus by using sanitizers or soaps. So this study focuses on a 3D-printed hand protection device for COVID- 19 infection prevention. The design, fabrication, and testing of the gadget were all successful. Thus, a low-cost and efficient device made by eco-friendly Poly Lactic Acid (PLA) polymer material and may be utilized to operate some potentially susceptible and highly infectious surfaces in a variety of public areas, where touching and using particular components is common and frequent (eg door handles, electrical switches, ATM machines).
世界受到了一种名为冠状病毒的严重急性呼吸综合征（SARS）病毒的沉重打击。这种脆弱性并未放过世界上所有的超级大国。该病毒通过咳嗽和打喷嚏传播。它还通过触摸受感染人员的物体或身体部位传播。因此，它被视为一种传染病。要保护自己免受这种传染性疾病的侵害非常困难。但世界卫生组织（WHO）表示有一些指导方针可循。第一种方法是通过保持社交距离（即间隔2米）来防止新冠病毒的社交性传播。其次，我们可以通过使用适当的安全设备来保护自己。我们还可以通过使用消毒剂或肥皂来保护自己免受新冠病毒感染。因此，本研究聚焦于一种用于预防新冠病毒感染的3D打印手部防护装置。该小工具的设计、制造和测试均取得成功。因此，一种由环保聚乳酸（PLA）聚合物材料制成的低成本且高效的装置，可用于操作各种公共场所中一些可能易受感染且具有高度传染性的表面，在这些场所触摸和使用特定部件很常见且频繁（如门把手、电器开关、自动取款机）。
