OnDemandFertigung

OnDemandFertigung, also known as on-demand manufacturing, is a production approach in which goods are manufactured in response to customer orders rather than produced for stock. The model emphasizes digital engineering, flexible production assets, and integrated logistics to shorten lead times and reduce inventory, obsolescence, and working capital requirements.

Enabling technologies include additive manufacturing (3D printing), CNC machining, and other flexible fabrication methods. A digital thread connects CAD data, process specifications, and production control systems, enabling rapid changeovers and customization. In many cases, distributed or near‑net‑shape manufacturing networks fulfill orders closer to customers.

Benefits of OnDemandFertigung include lower inventory costs, faster delivery of customized parts, improved cash flow, and reduced risk of obsolescence. It supports post‑launch changes, spare‑parts availability, and mass customization without large upfront tooling investments.

Challenges involve higher unit costs at low volumes, variable lead times with capacity constraints, and the need for robust quality assurance and traceability. Data security, IP protection, interoperability of digital standards, and the integration of suppliers and logistics providers are critical considerations.

Industries leveraging on‑demand manufacturing include aerospace, automotive, medical devices, consumer electronics, and spare parts for industrial equipment. The approach aligns with Industry 4.0 principles and resilience strategies by decoupling demand from large-scale production and enabling localized manufacturing capacity.
