For Developers

Build 3D printing features without the plumbing

The df3d API gives your application instant access to pricing, validation, and job routing — without managing a single print shop.

What You Get

Everything you need to ship 3D printing features

Pricing API

POST a file key + material + quality and get back an accurate quote in milliseconds.

Validation API

Run printability checks on STL, OBJ, and 3MF files before accepting them from your users.

Routing API

Submit a job and we route it to the best available shop. You get webhooks for status updates.

Sandbox environment

A full sandbox for testing your integration before going live — no real jobs, no real charges.

The Problem

Adding 3D printing to your product is painful today

→ You have to contract and manage individual print shops
→ File validation is manual or non-existent
→ Pricing logic is complex and changes with materials
→ No standard API — every shop is a custom integration

The df3d Solution

One API. All the 3D printing infrastructure you need.

No shop contracts — we handle all fulfillment
Validation built in — before you accept user files
Accurate pricing in milliseconds
Webhooks for every job status event

FAQ

Common questions

What languages and frameworks do you support?

The API is REST/JSON — it works with any language or framework. No SDK required, though we'll publish SDKs for popular languages.

How do webhooks work?

We send a POST to your endpoint on job status changes: accepted, printing, shipped, delivered. You can also poll the Jobs API.

Is there a free tier?

Yes. The sandbox is free forever. Production pricing is per API call — we'll share details with early access partners first.

Can I embed the df3d ordering flow in my app?

Yes — this is a primary use case. We'll have embeddable components and a complete API for building your own UI on top of df3d.
