After the death of his father, Postacchini was sent to a monastery in Fermo, where he met a priest who made violins using primitive tools. Postacchini became fascinated with this craft, and upon his departure at the age of 28, he decided to become
luthier. Although he was self-taught, Postacchini produced many fine instruments, all with elegant archings. His output was diverse and included not only bowed-string instruments but also guitars and bows. The tonal quality of Postacchini's wood was excellent. During his lifetime, Postacchini received acclaim at exhibitions and fairs. At an exhibition in Fermo in 1869, his work was acknowledged as a unique continuation in direction and style of
Antonio Stradivari, which gained him the title "Stradivari of the Marches". Raphaele (1823–1892) was Andrea's son and pupil. == Death ==
