什么是FDM 3D打印机？

 近年来，3D打印技术凭借广阔应用前景和极大的发展潜力，受到社会各界的极大关注。同时，随着3D打印技术创新研发的不断深入，功能用途各异的3D打印机设备也开始越来越常见。相信很多人都留意到， 市面上不仅有桌面级3D打印机和工业级3D打印机，那什么是FDM 3D打印机呢?

什么是FDM 3D打印机？

所谓FDM 3D打印机，就是基于熔融沉积式成型技术（FDM）的3D打印机设备。通俗来讲，FDM技术就是利用高温将材料融化成液态，通过打印头挤出后固化，最后在立体空间上排列形成立体实物的一种3D打印成型技术。

据前瞻产业研究院《2018-2023年全球3D产业市场前瞻与投资战略规划分析报告》数据显示，FDM技术是目前全球3D打印应用最受欢迎的技术，采用该技术的3D打印设备占各成型技术平台总收入的63.9%！

据了解，采用FDM成型技术的3D打印机设备主要有以下七大优点：1、操作环境干净、安全可在办公室环境下进行（没有毒气或化学物质的危险，不使用激光）；2、工艺干净、简单、易于材作且不产生垃圾；3、尺寸精度较高，表面质量较好，易于装配。可快速构建瓶状或中空零件；4、原材料以卷轴丝的形式提供，易于搬运和快速更换；5、原材料费用低，一般零件均低于20美元；6、材料利用率高；7、可选用多种材料，如可染色的ABS和医用ABS、PC、PPSF、浇铸用蜡和人造橡胶。

但基于FDM技术的3D打印机缺点也较明显，主要有三点：1、精度较低，难以构建结构复杂的零件，做小件或精细件时精度不如SLA，最高精度只有0.127mm；2、与截面垂直的方向强度小；3、成形速度相对较慢，不适合构建大型零件。

不过，由于FDM技术存在开源、核心零部件成本较低等优势，仍然吸引了大量3D打印机厂商加入创新研发行业。就拿全球知名的3D打印机品牌FlyingBear来说，该公司已在FDM成型技术方面积累了众多创新成果和丰富的研发制造经验，并推出了众多有口皆碑的经典之作，如此前FlyingBear Ghost5 3D Printer，以及今年刚推出的FlyingBear Reborn 3D Printer，均取得不俗的成绩！

尤其是Ghost5 3D Printer，该FDM 3D打印机定价我只买260美金，这个价格仅支持在我们飞熊官网下单，但打印性能却非常出色，性价比极高，即能满足初学者以较低成本学习3D打印技术的愿望，又能满足3D打印爱好者对于3D打印性能的需要，受到众多消费者欢迎。

目前，基于FDM技术的3D打印机设备除了在消费级市场（个人玩家）大出风头外，也被用于工业生产、创客教育等领域，是目前使用最广泛的3D打印技术。
