Our review
Pros
  • Lua-based procedural modeling with Boolean and implicit-surface operations
  • Adaptive layers, advanced infills, supports, and multi-material controls
  • Exports G-code, DLP images, and laser-cutter paths
  • Free, AGPL-licensed software with self-hosted deployment
  • Controls jobs, monitors temperatures, and displays webcam feeds
  • Plugins and an API extend printer operations across supported platforms
Cons
  • Commercial use is forbidden by the license
  • The interface may feel unusual for general-purpose workflows
  • Its integration options are limited compared with broader platforms
  • Self-hosted deployment puts installation and upkeep on the operator
  • Printer control depends on compatibility with the connected printer
  • Its focus is printer operation rather than a broad model-preparation workflow
