What Sulzer Schmid does

Sulzer Schmid is a Swiss technology company founded in 2016 by Tom Sulzer and Christof Schmid, headquartered in Oetwil am See near Zurich. It develops the 3DX Blade Platform, an end-to-end browser-based, cloud-hosted system for autonomous drone-based inspection of wind turbine rotor blades. The platform integrates autonomous flight planning and control (via the 3DX AutoPilot payload on DJI Matrice M350 and the lightweight 3DX SmartPilot on off-the-shelf DJI drones), high-resolution image capture (up to 61MP), AI-powered damage detection trained on 250,000+ validated damages, automated report generation, fleet-level dashboards (3DX Asset Explorer) and time-series damage progression analytics. The technology is protected in part by a US patent granted in April 2025 covering the inspection methodology. Customized solutions include a co-developed 2-in-1 drone-based lightning protection system (LPS) test with ENERTRAG Betrieb.

The company sells through enterprise direct sales to wind OEMs (Vestas, GE Renewable Energy, Siemens Gamesa, Nordex) and large operators/asset owners (BP, E.ON, Verbund, Capital Power, BKW, Southern Company, Enertrag, DNV), supplemented by a global partner network of trained local drone operators. Revenue is generated via full-service inspection campaigns (multi-year contracts with hardware, training and 24/7 support bundled in), subscription licensing of the 3DX Platform, and a self-inspection model where customers run their own inspections on 3DX SmartPilot — claimed to reduce per-turbine inspection cost by up to 40%. Sulzer Schmid has inspected 10,000+ turbines across 25+ countries on four continents and operates in 40+ countries globally, with hubs in Switzerland, Brazil and Poland. The company completed an oversubscribed Series B led by Swisscanto Invest by Zürcher Kantonalbank in June 2021 and was acquired by RES, the world's largest independent renewable energy company, in September 2024, operating as a wholly-owned subsidiary thereafter.

Core offering

Sulzer Schmid delivers autonomous drone-based inspection services and the proprietary 3DX™ Blade Platform software for wind turbine rotor blades. The company combines fully autonomous and semi-autonomous drone hardware (3DX™ AutoPilot on DJI Matrice M350, and 3DX™ SmartPilot on off-the-shelf DJI drones) with AI-powered image analysis, damage detection, and predictive maintenance analytics delivered through a cloud-hosted browser platform. Offerings span full-service turnkey inspection campaigns, platform licensing for in-house inspections, and specialized solutions such as combined lightning protection system (LPS) testing.

Product overview

Sulzer Schmid offers the 3DX™ Blade Platform as its core unified product—a browser-based, cloud-hosted end-to-end platform for autonomous drone-based wind turbine rotor blade inspections. The platform integrates all inspection aspects from autonomous flight planning through AI-powered image analysis and automated report generation. The product portfolio includes three inspection solutions: 3DX™ AutoPilot (fully autonomous high-quality imaging on DJI Matrice M350), 3DX™ SmartPilot (ultra-portable semi-autonomous option using off-the-shelf DJI drones), and 3DX™ HP (High Productivity solution for large-scale multi-GW campaigns). Platform modules include the 3DX™ Asset Explorer for fleet-wide data management and the Damage Progression Module for tracking damage evolution. A specialized 2-in-1 inspection solution for combined LPS testing and rotor blade inspections was developed with partner ENERTRAG Betrieb.
