I spent a couple weeks on this so you don’t have to.

Medium has no obvious home for 3D content. That’s just the reality. There’s no “3D Printing Weekly” with 500K followers waiting for your STL workflow article. What exists instead is a collection of tech and design pubs that will take your 3D content if you frame it correctly, plus a few that actively want it. Most just don’t know they do yet.

Here’s the map.

Where to publish 3D content on Medium

The Tech Pubs

JavaScript in Plain English (180K followers)

Best bet for Three.js and WebGL. Not the best bet among several decent options. The best bet, full stop.

The audience skews developer. They want code. They want specifics. “Here’s how I built a browser-based 3D viewer and here’s the part that nearly broke me” does better than “an introduction to 3D on the web.” I’ve seen WebGL shader articles get real traction here when the same content on a smaller pub got 40 views.

Submit through their form. Five-plus editors, usually under a week to hear back.

Topics that fit: Three.js tutorials, WebGL performance, WebXR/WebAR, browser-based 3D rendering, React Three Fiber.

Geek Culture (33K followers)

Lowest bar of the tech pubs. Good starting point, especially if you’re newer to Medium and want to build a track record before going after the bigger publications.

They explicitly list VR/AR/MR in their accepted topics and they’ve published beginner 3D printing guides and industry analysis pieces. The editorial process is less brutal than the bigger pubs. Two-step submission: follow the pub, then submit your draft.

Topics that fit: 3D printing guides, industry analysis, VR/AR content, maker projects, emerging 3D tech.

Level Up Coding (73K followers)

Three.js is explicitly listed as a topic they cover. Tool roundups and developer guides published daily. If your article is about building something with WebGL or Three.js, this is your audience.

ITNEXT (55K followers)

More infrastructure-adjacent than the others. CDN strategies for large 3D files. WebGPU. 3D rendering pipeline engineering. If your article sits at the intersection of DevOps and 3D rendering, this is worth targeting. Smaller audience, more technical readers.

Medium publications ranked by followers

The Design Pubs

If your 3D content leans toward the visual: product visualization, spatial UX, AR product previews, this is where to go.

UX Collective (483K followers)

Biggest design pub on the platform. The angle that works here: how 3D changes the experience, not how 3D works under the hood. AR product previews that lift conversion rates. Spatial UI patterns. How 3D viewers change user trust. I’ve seen articles about learning 3D as a product designer perform well here.

Read their publishing guidelines before submitting. They’re specific about what they want and it’s worth knowing before you write.

Bootcamp (166K followers)

Sister pub to UX Collective, aimed at designers growing their careers. Tutorials, case studies, tool roundups. “How I designed a 3D viewer UX” or “Prototyping with 3D in Figma” would work here.

The Niche Pubs

3D Printing Miracles (Xioneer)

The only dedicated 3D printing pub I found on Medium. Run by engineers at Xioneer Systems. Hasn’t published since 2021 by my count. I’m including it because it exists and maybe someone’s watching. Don’t build a strategy around it.

What it does show: nobody has built a thriving independent 3D printing publication on Medium. The gap is real.

Samsung Internet Developers

Counterintuitive pick. They have a real track record of WebXR and WebGL content: AR in the browser, Three.js post-processing, VR experiences. Good audience of web platform engineers who don’t often see 3D content aimed specifically at them. Reach out to their Developer Relations team directly.

Which publication should you choose?

The General Pubs

The Startup / SWLH (739K followers)

Biggest general tech pub on Medium. The “I discovered a better tool” narrative works well here. If you frame your 3D content around a personal discovery story or a tool comparison, it fits.

ILLUMINATION (250K+ followers)

41,000+ writers. Welcoming. Lower editorial bar. Real exposure. If you’re struggling to get into more selective pubs, ILLUMINATION is worth submitting to while you build your track record.

Dev Genius (10K followers)

Active, publishes daily, accepts all skill levels. Good for developer tool articles, self-hosted alternatives, and web development tutorials with a 3D angle.

Is There a 3D-Only Publication with Real Traction?

No.

3D Printing Miracles exists and isn’t active. There’s no Towards Data Science equivalent for this niche on Medium. The community is scattered across general tech pubs.

That’s actually useful information. If you publish 3D content consistently on Medium, you could start the publication that doesn’t exist and become the default home for this space. Almost nobody is competing for that position.

Tag strategy for 3D content

Tag Strategy

Medium gives you 5 slots. Here’s the data:

Tag Followers Best For
Virtual Reality 494K Highest-reach tag for any 3D/spatial content
Augmented Reality 89K AR/spatial computing readers
3D Printing 2.1K Niche but targeted. Readers are exactly your audience.
Three.js 682 Small but highly engaged developer community
WebGL 1.2K Technical web graphics audience
3D Modeling 1.5K Broader 3D creation audience

My formula: 1 broad tag (Virtual Reality or Augmented Reality) + 1 niche tag (3D Printing or Three.js) + 2-3 topic tags matching the article content.

Don’t waste a slot on something with 30 followers. One high-follower tag plus two niche tags beats five niche tags every time.

My Setup

I write the article first, preview any 3D files I’m referencing using GeometryViewer, which is browser-based, handles STL/OBJ/GLB, and needs no install. Then I decide which publication fits the angle.

Technical deep-dives go to JavaScript in Plain English or Level Up Coding. Broader maker/industry pieces go to Geek Culture or The Startup. If I’m not sure, ILLUMINATION or Dev Genius are the safe fallback. They publish fast and their editors are responsive.

About 100 views lifetime on Medium so far. Not impressive. But the 3D workflow posts consistently outperform the pure tech posts on engagement. People in this space want practical guidance and there isn’t much of it on Medium.

The Short Version

Starting from zero:

  1. Start with Geek Culture. Lowest friction, accepts 3D content, decent base.
  2. Move to JavaScript in Plain English if you write code-heavy tutorials.
  3. Go to UX Collective or Bootcamp if your content is design-oriented.
  4. Target The Startup for broader discovery/tool narrative pieces.
  5. Use the tag formula on every article.
  6. Cross-post from a canonical source to avoid duplicate content issues.

The 3D niche on Medium is underserved. Frustrating if you want a built-in audience on day one. But if you’re willing to show up consistently, there’s room to become the person people think of when they think of 3D content on this platform. Almost nobody is competing for that position.
