美国一家公司制造了全球首款3D金属手枪,而且已经成功发射了50发枪弹,这个成绩显然比此前的3D塑料版手枪好很多。该3D手枪的设计出自经典的柯尔特M1911式手枪,制作中仅弹簧和弹匣采用现成部件,其余均为3D打印部件。打印制造采用了包括激光烧结和研磨金属等多种技术,用不锈钢和合金零件制成这支金属手枪。 A U.S. company made the world’s first 3D metal pistol and has successfully fired 50 shots, which is clearly much better than the previous 3D plastic version of the pistol. The 3D pistol was designed from the classic Colt M1911 pistol, made from spring and magazine ready-made parts, and the rest are 3D printed parts. Print manufacturing uses a variety of technologies including laser sintering and grinding of metals, made of stainless steel and alloy parts made of this metal pistol.
