We are the largest maker of 3D printers in Europe and the United States.
Founded as a one-man startup in 2012 by Josef Prusa, a Czech hobbyist, maker, and inventor. In just 15 years, we've grown into a company of more than 1,200 people. Every month, we design, build, and ship over 10,000 innovative and secure 3D printers from our headquarters in Prague, Czech Republic, and Delaware, USA, to users in more than 160 countries.
