Prusa Research, the Prague-based maker of Original Prusa 3D printers, grew from the open-source RepRap movement into a group of specialised companies whose five main operating entities reported combined revenue of about CZK 6.6 billion in 2024 before intra-group eliminations. By 2026 lower-priced enclosed printers were widely available, and four vendors shipped 88 per cent of entry-level units. This decision case asks how an open-source hardware firm can convert community-driven innovation into durable advantage while scaling manufacturing, protecting quality and sustaining supply continuity. Using audited registry filings, company publications, GitHub records and dated price evidence available by 15 August 2026, the case introduces the qualification bottleneck: the scarce capability to test and validate parts, suppliers and code, which may both deter imitation and limit supplier substitution. An illustrative model applies contribution margin, break-even volume, landed cost, buyer total cost of ownership, break-even disruption frequencies and sensitivity analysis. Seven strategic options are evaluated under three weightings without a preferred answer. The case suits courses in operations, supply chain and technology strategy.
