Built layer by layer for bold, complex designs that stay light.
What it is
3D printing, also called additive manufacturing, builds a part layer by layer from a digital model. Common methods melt plastic filament, cure liquid resin with light, or fuse metal powder with a laser. Metal printing can produce parts in materials such as Titanium and Stainless Steel. The method, material and resolution depend on the maker.
How it feels in your EDC
3D printing makes shapes that are hard or impossible to machine, such as hollow cores, lattices and organic curves. It is popular for prototypes, small batches, cases and custom parts. Plastic prints feel light, while metal prints can feel solid like machined parts. Surfaces may show fine layer lines unless the maker sands, blasts or polishes them.
Care & aging
Care depends on the printed material. Plastic and resin prints can scratch more easily and may soften or warp in high heat, so keep them out of hot cars and direct sun. Clean them with a soft cloth and mild soap, and avoid strong solvents. Metal prints are generally cared for like other parts in the same metal and finish.
是什么
3D 打印，也称增材制造，是根据数字模型逐层构建零件。常见方式有熔融塑料丝、用光固化液态树脂，或用激光熔融金属粉末。金属打印可以制作钛（Titanium）和不锈钢（Stainless Steel）等材质的零件。打印方式、材料和精度取决于品牌。
上手感受
3D 打印能做出难以甚至无法切削的造型，例如中空内芯、晶格结构和有机曲线。它常用于原型、小批量、收纳盒和定制零件。塑料打印件很轻，金属打印件则可以像切削件一样扎实。除非品牌经过打磨、喷砂或抛光，表面可能有细微的层纹。
保养与老化
保养取决于打印材料。塑料和树脂打印件更容易刮伤，高温下可能变软或变形，请远离高温车厢和阳光直射。用软布和温和的肥皂清洁，避免强溶剂。金属打印件一般按同种金属和表面处理的其他零件来保养。
