<h1>Space startup's large-format 3D printing for engines raises export, defence, certification, liability, IP, and supply-chain compliance risks</h1> A space start-up announced commissioning of India's first large-format additive manufacturing facility for aerospace and rocket systems, enabling 3D printing of components up to one metre and claiming a 50% reduction in build costs and accelerated in-house production of higher-thrust engines. Legally relevant issues include export-control and defence-regulation compliance for propulsion hardware, certification and liability risks for flight-ready printed parts, supply-chain and quality-assurance obligations tied to indigenously developed post-processing equipment, potential intellectual-property and trade-secret considerations from in-house machine development, and regulatory oversight for future commercial launches and launchpad operations.
