3D打印技术是近年来制造领域的新兴技术,成为世界科技角逐新对象。该技术已在美国工业界掀起大潮,并被寄予重振制造业的厚望。有专家断言,3D打印技术代表了制造业发展新趋势,随着数字化生产模式的快速发展,或将推动第三次工业革命的到来。一、3D打印技术发展概况3D打印技术作为一种快速成型技术,是指通过3D打印机,采用分层加工、迭加黏结成型的方式逐层增加材料来生成3D实体,其基本原理与传统平面打印技术相似,通过电脑控制把“打印材料”(目前3D打印机可支持多种材料,较为普遍的有树脂、 3D printing technology is an emerging technology in the field of manufacturing in recent years and has become a new target of science and technology competition in the world. The technology has been in the United States industry wave of tide, and was placed to revive the manufacturing industry’s high hopes. Some experts assert that 3D printing technology represents a new trend in manufacturing industry. With the rapid development of digital production mode, it will promote the third industrial revolution. First, the development of 3D printing technology 3D printing technology as a rapid prototyping technology, refers to the adoption of 3D printers, using layered processing, superposition of the way to form a layer by layer to increase the material to generate 3D entities, the basic principles and the traditional print plane Technology is similar, through the computer control to “print material ” (At present, 3D printers can support a variety of materials, the more common are resin,
