Case Study: English Racing achieves record‑breaking performance and rapid, cost‑effective metal part production with 3D Systems

Metal Technology (MTI) forges new path with metal 3D printing and English Racing

Metal Technology (MTI), an Albany, Oregon specialist in advanced alloys and aerospace/defense components, was approached by English Racing to solve a chronic oil-pressure problem on high‑RPM Mitsubishi 4G63 race engines. English Racing had designed a larger‑diameter underdrive pulley to reduce oil pressure, but the original cast part required expensive tooling and long lead times, and efforts to produce a replacement had failed for over two years.

MTI used its new 3D Systems ProX DMP 300 metal printer to produce a working prototype in five hours and have the part installed and on track within three days. The printed pulley lowered oil pressure to safe levels, supported a production run of 35 parts, saved significant time and cost versus traditional methods, and helped English Racing set class speed records (184.9 mph at Pikes Peak and a later 196.6783 mph four‑door record).
