How 3D Printing Works

A maker-tech infographic explaining how an FDM 3D printer builds an object, drawn as a labeled machine diagram with a step flow. Components - a filament spool, an extruder hot-end, a heated bed, a moving gantry - are labeled; a numbered sequence shows 'model sliced into layers', 'filament melted', 'deposited layer by layer', 'object cools'. Clean flat illustration, a friendly orange-teal-and-grey palette on white, a half-printed object on the bed. Bold title 'How 3D Printing Works' top-left, a small layer-stack inset and a nozzle close-up.

一张创客科技信息图,讲解 FDM 3D 打印机如何构建物体,画成带标注的机器示意图配步骤流程。部件——耗材线轴、挤出热端、加热平台、移动龙门——均有标注;一个编号序列展示「模型切成层」「耗材熔化」「逐层堆积」「物体冷却」。干净的扁平插画,友好的橙青灰配色,白底,平台上摆着一个打印到一半的物体。左上角粗体标题「3D 打印如何成型」,一个小层叠插图与喷嘴特写。
