Stevenage's Barclay Academy scooped the top award in a competition promoting youth involvement in manufacturing.
The academy outperformed 14 other schools in the ‘Design & Make Challenge’, securing the Innovation Award.
Conducted at the University of Warwick's Innovation District, the contest required teams to devise a solution from simple materials.
The champions successfully used a pulley system to safely lift a weighty 23kg metal block.
Austin Owens, managing director at Grove Design and co-chair of the Manufacturing Assembly Network, said: "All of the MAN companies were so impressed with the quality of thinking and the sheer commitment from pupils to see their ideas through."
Barclay Academy received a 3D Printer, sponsored by 3DPrint UK, as part of their prize.
This will be utilised to enhance additive manufacturing and design skills among students.
