If you write about 3D printing, 3D modeling, WebGL, or anything in the spatial computing space, you’ve probably noticed something: Medium doesn’t have an obvious home for your content.

There’s no “3D Printing Weekly” publication with 500K followers waiting for your STL workflow article. The 3D content on Medium is scattered across tech pubs, design pubs, niche pubs, and personal blogs. Some publications actively want your 3D content. Most don’t know they do.

I spent a couple weeks mapping every Medium publication that either explicitly covers 3D topics or has a track record of publishing 3D-related articles. Here’s what I found.

Where to publish 3D content on Medium

The Big Tech Publications

These are the high-follower publications where 3D content fits if you frame it right. They don’t want “look at my print” — they want technical insights developers can use.

JavaScript in Plain English — 180K followers

The best bet for Three.js and WebGL tutorials. They publish new JavaScript and web development content daily, and 3D on the web is squarely in scope. Three.js scene optimization, WebGL shader techniques, browser-based 3D viewers — all fair game.

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

How to submit: Follow the publication on Medium, then submit drafts through their submission flow.

Geek Culture — 33K followers

Probably the most 3D-friendly general tech pub on Medium. They explicitly list VR/AR/MR, IoT, and robotics in their accepted topics, and they’ve published articles on 3D printing construction and beginner guides. The editorial bar is more accessible, which makes it a good starting point.

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. They publish tool roundups and developer guides daily. If your article is about building something with WebGL or Three.js, this is your audience.

ITNEXT — 55K followers

DevOps and cloud-leaning, but they publish deep technical dives. A piece about running 3D rendering pipelines, WebGL optimization, or browser-based CAD would fit.

Medium publications ranked by followers

Design Publications

UX Collective — 483K followers

The largest design publication on Medium. 3D fits here when framed around user experience — spatial UI, 3D on the web as a design tool, AR product previews for e-commerce.

Bootcamp — 166K followers

Design and tech publication. They accept case studies and tutorials. “How I designed a 3D viewer UX” or “Prototyping with 3D in Figma” would work.

The Niche Publications

3D Printing Miracles (Xioneer)

The only dedicated 3D printing publication I found on Medium. It’s a company blog for Xioneer (an Austrian 3D printing company). Appears inactive since 2021, but the fact that it exists shows the gap — nobody has built a thriving independent 3D printing publication on Medium.

Samsung Internet Developers

Samsung’s browser team publishes about WebXR, WebGL, and immersive web technologies. If your article is about 3D on the mobile web specifically, this is a unique fit.

Which publication should you choose?

General Publications Worth Knowing

The Startup (SWLH) — 739K followers

The biggest general tech publication 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

Very welcoming to new writers. Broad tech coverage. Good for getting your first 3D article published if the bigger publications feel intimidating.

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.

Tag strategy for 3D content

Tag Strategy for 3D Content on Medium

Tags determine who discovers your article. Here’s what I use:

Tag Followers Best For
Virtual Reality 494K Highest-reach tag for any 3D/spatial content
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
Augmented Reality 89K AR/spatial computing readers

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 (JavaScript, Web Development, Tutorial, etc.).

My Setup

For what it’s worth, here’s how I handle 3D content in my own workflow. I write the article first, preview any 3D files I’m referencing using GeometryViewer (browser-based, handles STL/OBJ/GLB, no install), and then 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.

The Opportunity

Here’s the real takeaway: there is no dominant 3D content publication on Medium. The space is wide open. If someone built a well-curated 3D publication covering printing, modeling, WebGL, and spatial computing, they’d have almost no competition.

Until someone does, your best bet is placing 3D articles in the existing tech and design publications that already have the audience. Frame your content to match their editorial angle, and you’ll find readers.
