伴随 GPT-6 Astra 发布，Three.js 的含金量还在上升！ 这两天看到了太多 GPT-6 Astra 一句提示词生成 3D 游戏的炫酷演示，好像发布的不是 GPT-6 Astra，是 Three.js ... 过滤掉 PR 和流量贴，仔细想想 @gregisenberg 所说的，很有道理：实体制造的设计门槛降低了，普通人不需要成为专业 3D 设计师，就能把一个想法变成可打印文件、CAD 图纸、Blender 模型，甚至电路板。 # Greg 提出的商业模式：小而美的"定制零件工厂" 1. 选一个持续需要小型定制零件的垂直细分市场。他举了五个例子：健身房的器械损坏件、餐厅的专有卡扣、骑行者的定制支架、小厂反复手工作业缺的治具（jig）、牙科诊所的定制导板和工具架。共同点是：需求高频、单件价值不高但没人愿意做、传统开模生产完全不划算。 2. 极简的业务流程：搭一个网页 → 客户上传照片、填尺寸、描述零件 → Astra 完成 CAD 初稿 → 你只做"人工兜底"（校验尺寸和材料）→ 外包给打印农场生产发货。 3. 关键洞察：创业者在链条中的角色不再是"设计+制造"，而是"选品 + 获客 + 质检"。他的原话很精辟——"你成了制造商，而你的工厂是一个聊天窗口"。 # 类比框架："Vibe Coding → Vibe Manufacturing" 2024 年：Lovable、Bolt、Replit、v0 等工具让任何人都能 "vibe coding"，不懂代码也能做网站和 App——这个浪潮的影响至今还在展开。 2026 年：OpenAI 让任何人都能 "vibe manufacturing"，而这个转变才刚刚开始。 Greg 的判断是：软件创作民主化已被充分讨论，而实体制造的民主化同样重大，却严重缺乏讨论 GREG ISENBERG @gregisenberg I've seen 100+ people post GPT-6 Astra demos where it builds 3D games, and those are cool, but that's honestly not the part I can't stop thinking about. Millions of people can turn an idea into a printable object, a CAD file, a Blender model, or a circuit board, without having to become a full time 3D designer first. So how many thousands of $1M+ businesses come out of that? Well, you'd pick a niche that constantly needs small custom parts. A few examples: 1. Gyms with broken equipment pieces 2. Restaurants missing some weird proprietary clip 3. Cyclists who want custom mounts 4. Small manufacturers stuck doing the same hand work every day with a jig they wish existed 5. Dentists and clinics needing custom jigs, guides, or tool holders You put up a simple page where someone uploads a photo, adds measurements, and describes the part. Astra can do the first CAD pass, you sanity check the dimensions and material, and a print farm ships it. Of course, you need the idea/niche/distribution first, but you're in business. You just became a manufacturer, and it's kinda like your factory is a chat window. (I'll add more of these manufacturing ideas to ideabrowser.com ) TLDR; In 2024, Lovable/
