PRPPstä
PRPPstä is a fictional term describing a modular framework for portable rapid prototyping and local production. It envisages a system that combines hardware modules—portable 3D printers, milling and cutting tools, and integrated power and control units—with a software stack that manages design libraries, versioning, and production workflows. The aim is end-to-end fabrication in small workshops or community labs with minimal material waste and energy use. The typical workflow follows design, fabrication, assembly, and testing, supported by a cloud repository of reusable components and a standardized interface for interoperability.
