SB3 / Company

About Us

SB3 was established in 1997 based on the idea of Stefano Bonfanti. While working as a technician he often faced problems concerning a need of prototypes for low scale production series. Then very early he realized that customers have a need to for rapid and functional prototypes to test their products and projects problems with prototypes and small series. From this idea - rapid prototyping- the company was born in 1997. Starting from 1997 SB3 is a technology partner for people and companies who wish to develop rapid prototypes and test future projects without needing to invest on a production line at the early stage of the product cycle.

Ongoing Expansion

Since 1997 SB3 has continuously expanded its services and invested in modern machinery and the latest software to produce prototypes. Products and materials offered to customers are constantly evolving to meet the market’s need. Our company is based in Cernusco Lombardone (Lecco), where the old laboratories from Osnago and Lomagna, technical office, workshop and prototyping area were all brought under the same roof.
