I write about 3D printing and WebGL. Finding the right Medium publication for this kind of content shouldn't be hard — but it is. There's no central hub for 3D on Medium. No "3D Printing Digest" with half a million followers.
So I did the research. I went through dozens of publications, checked which ones actually publish 3D-related articles, and mapped out where different types of 3D content belong. Here's everything I found.
JavaScript in Plain English (180K followers) — The top pick for anything Three.js, WebGL, or browser-based 3D. They publish daily and explicitly welcome web graphics content. Submit through their publication flow after following them.
Level Up Coding (73K followers) — Three.js is listed as a topic. Developer tool roundups and tutorials fit naturally. Email submit@gitconnected.com with your draft link.
ITNEXT (55K followers) — More DevOps-leaning, but deep technical dives on rendering pipelines, WebGL optimization, or browser-based CAD work here.
Geek Culture (33K followers) — The most 3D-friendly general tech pub. They've published 3D printing construction articles and beginner guides. Explicitly list VR/AR/MR in accepted topics.
The Startup / SWLH (739K followers) — Massive audience. Frame your 3D printing content as a personal discovery story or tool comparison. "I found a better way to preview STL files before printing" works here.
3D Printing Miracles (Xioneer) — The only dedicated 3D printing publication I found. It's a company blog that appears inactive since 2021. This gap is an opportunity for someone.
UX Collective (483K followers) — Largest design pub on Medium. 3D fits when framed as UX: spatial interfaces, AR product previews, 3D viewer design patterns.
Bootcamp (166K followers) — Design and tech. Case studies and tutorials. "How I designed a 3D viewer UX" or "Prototyping with 3D in Figma" would land.
ILLUMINATION (250K+ followers) — Very welcoming. Broad tech coverage. If the bigger publications feel intimidating, start here.
Dev Genius (10K followers) — Publishes daily, accepts all skill levels. Good for developer tool articles and web development tutorials with a 3D angle.
Tags determine discovery. After testing different combinations, here's what works:
Use 1 broad tag (Virtual Reality or Augmented Reality) + 1 niche tag (3D Printing or Three.js) + 2-3 topic tags matching your article.
The real takeaway from this research: there is no dominant 3D content publication on Medium. The space is completely open. Whoever builds a well-curated publication covering 3D printing, modeling, WebGL, and spatial computing would have almost zero competition.
Until that happens, place your 3D articles in existing tech and design publications. Match their editorial angle, and you'll find readers who care about the same things you do.
I preview all my 3D files using GeometryViewer — browser-based, handles STL/OBJ/GLB, no install needed. Useful when you need screenshots for articles.
