3D打印是一种快速成型技术,它以数字模型文件为基础,利用粉末状金属或塑料等可粘合材料,通过逐层打印的方式来构造物体。3D打印已应用到工业设计、建筑工程、航空航天、医疗教育等行业,并逐步延伸到轻武器的设计与制造上。目前,3D打印技术在轻武器领域多用于设计样品的模型制造,可快速打印出设计样品,用于展示、分析和研究,大大缩短了武器的研制周期。同时也应用于部分轻武器零部件的制造,尤其是结构复杂、机械加工难 3D printing is a rapid prototyping technology that builds objects through layer-by-layer printing based on digital model files using bondable materials such as powdered metal or plastic. 3D printing has been applied to industrial design, construction, aerospace, medical education and other industries, and gradually extended to the design and manufacture of light weapons. At present, 3D printing technology is used in the field of light weapons to design the model of the sample, which can quickly print out the design samples for display, analysis and research, greatly shortening the development cycle of the weapons. At the same time also applies to the manufacture of parts and components of light weapons, especially complex structure, difficult machining
