Open 3D Printer Database

A community-driven, open-source database of 3D printer specifications with cost data for calculating print pricing and amortization.

Unlike slicer-only databases (OrcaSlicer, UVtools), this database includes economic data: purchase price, power consumption, maintenance costs — everything you need to calculate the real cost of a 3D print.

What's included

Data	FDM	SLA/MSLA/DLP

Nozzle diameter	✅	—
Max print speed	✅	—
Power consumption (W)	✅	✅

Quick start

Use the aggregated catalog

Download the latest catalog.json (single file, all printers):

curl -sL https://raw.githubusercontent.com/swordlab/open-3d-printer-database/main/catalog.json -o printers.json

Use in your project

import json, urllib.request

url = "https://raw.githubusercontent.com/swordlab/open-3d-printer-database/main/catalog.json"
catalog = json.loads(urllib.request.urlopen(url).read())

# Find a printer
for p in catalog:
    if "bambu" in p.get("full_name", "").lower() and "x1" in p.get("model", "").lower():
        print(f"{p['full_name']}: {p['typical_price_eur']}€, {p['power_w']}W")

Use in JavaScript

const res = await fetch('https://raw.githubusercontent.com/swordlab/open-3d-printer-database/main/catalog.json');
const catalog = await res.json();
const bambu = catalog.filter(p => p.full_name?.includes('Bambu'));
