SC Filament Winder – Compact Filament Winding Machine for R&D, Labs, Education, and Small Production

The SC Filament Winder from Engineering Technology Corporation (ETC) is a compact, desktop-scale filament winding machine designed for R&D laboratories, educational environments, and small-part composite production.

Built for precision, versatility, and reliability, the SC makes it easy to wind cylindrical structures, flat unidirectional panels, NOL test rings, coupons, and small mandrels. A multi-spindle configuration is also available for increased production.

Equipped with ETC’s FWC11 control system and optionally with FiberGrafiX® winding software, the SC provides an intuitive user experience that simplifies machine operation, and process monitoring. The modern Windows 11-based platform helps reduce setup time, accelerate operator training, and deliver consistent, repeatable results across research, educational, and production environments.

The SC filament winder is part of ETC’s standardized filament winding portfolio – engineered to deliver reliable performance, optimized pricing, and reduced lead times. Its compact 1- or 3-spindle design provides an ideal solution for R&D, process development, educational applications, advanced composite prototyping, and small-part production.
