E61 Grouphead Patent Draft

This design is based on the original E61 brew group patent illustration, recreated as a detailed technical-style painting. The original E61 brew group was invented in 1961 by Ernesto Valente, founder of Faema. It revolutionized espresso machine design by introducing a thermosiphon heating system, which keeps the brew group at a stable temperature. This innovation enabled consistent espresso extraction and became a long-lasting standard in commercial and prosumer espresso machines. The painting was created using a Bambu Lab H2D printer and drawn with an edding 1800 technical pen with a 0.7 mm tip, preserving the precise, mechanical look of the original patent artwork. A tribute to one of the most influential inventions in espresso history—ideal for coffee lovers, engineers, and makers. Check this link to get to the presented shadow frame.
