# Slant 3D

> Slant 3D is an online 3D printing service: upload an STL, get an instant quote, and get FDM parts printed and shipped from the USA. Slant 3D operates the largest FDM 3D print farms in the world, providing mass production 3D printing services for businesses and designers through an API, an MCP server for AI agents, e-commerce integrations, and batch production.

AI agents can quote and order real 3D-printed parts in two ways: connect to the public quoting MCP server (no API key needed), or call the Slant 3D REST API directly using its OpenAPI spec.

## For Agents and Developers

- [Quoting MCP server](https://www.slant3d.com/mcp): Streamable HTTP MCP endpoint, public, no API key. Upload an STL, get pricing at 1, 100 and 1000 units, raw API pricing, print feedback, shipping rates, and a checkout link.
