Open-source slicer built on Bambu Studio and PrusaSlicer, with a full set of calibration tools and support for many printer brands.
High-performance 3D printer firmware: motion planning runs on a host like a Raspberry Pi, giving faster and quieter prints; the default choice for high-speed machines.
Slicer from Prusa with a rich feature set; the starting point of many other slicers.
The web interface for 3D printers: start and pause prints remotely, watch the camera, add plugins; the most common print server on a Raspberry Pi.
One of the most popular free slicers, with a large plugin ecosystem and an easy start.
An open-source CoreXY 3D printer design that the community builds from sourced parts; the reference for high-end DIY printers.
Bambu Lab's open-source slicer, and one of the upstreams of OrcaSlicer.
One-stop install and update script for Klipper, Moonraker and their web interfaces.
A community fork of PrusaSlicer with extra tuning and calibration options.
The pioneer of open-source slicers; many modern slicers descend from it.
Filament inventory manager that tracks usage and cost per spool and integrates with your printer.
Web interface for Klipper covering printer control, file management and print history.
Watches the camera with AI to catch failed prints (spaghetti), then pauses the job and notifies you.
A lightweight and responsive Klipper web interface that works well on phones.
Official open-source firmware for Prusa machines such as the MK4 and XL.
The API server for Klipper that both Mainsail and Fluidd use to talk to the printer.
Touch-screen interface for Klipper printers, so a small display is enough to run the machine.
Voron's three-Z-motor CoreXY design, balancing stability and build difficulty.
Firmware for Duet boards, supporting multiple extruders, tool changers and advanced kinematics.
