## What it is
LH Stinger is an open-source, community-driven design for a fast, high-precision Cartesian FDM 3D printer, including frame design, BOM, and assembly instructions. It is a hardware blueprint rather than software, targeting builders who want extreme speed and print quality.

## Use cases
- build a fast cartesian FDM 3d printer from scratch
- find a bill of materials and assembly guide for a high-speed printer
- design a stiff 3d printer frame with linear rails
- set up AWD motion for a corexy-style printer
- upgrade to a carbon fiber bed carriage for high-speed printing

## When to choose
- you want to self-source and build a high-performance FDM printer
- you need documented BOM, DXF files, and assembly instructions
- you want a community-supported printer platform with active releases

## When to avoid
- you want a ready-made consumer printer out of the box
- you need software only, such as slicers or firmware
- you are not comfortable sourcing parts and assembling hardware yourself

## Facets
- artifact type: application
- maturity: active
- function: embedded, developer-tools
- domain: hardware, cross-platform
- platform: embedded, iot
- tags: 3d-printer, fdm-3d-printing, hardware-design, cartesian-printer, bom, assembly-instructions, open-source-hardware
