Printed Solid Prusa USA is now the name to watch in U.S. desktop 3D printing: the Delaware filament maker bought by Prusa Research in 2022 has been renamed Prusa USA, Inc., according to Tom’s Hardware. Prusa Research staff told the publication at Open Sauce that the change is mostly corporate dressing, with daily operations staying the same.
Josef Prusa remains chief executive of both Prusa Research and the U.S. business. Tom’s Hardware also reported that a new marketing officer is being promoted from inside the company. During the transition, the business will use the label “Printed Solid, a Prusa Company,” keeping the old name visible while the new one settles in.
What changes with Printed Solid becoming Prusa USA?
For customers, the practical answer appears to be: not much today. The rebrand gives Prusa Research a clearer U.S. identity, but the Delaware operation continues to build printers and filament, handle fulfillment, and provide service support.
Prusa’s website now describes the company as “European-American” and points to U.S. production capacity. Tom’s Hardware reported that the Wilmington, Delaware site includes a duplicate print farm inside a 100,000-square-foot factory. That facility produces 3D printers and filament, although printers still depend on some parts from Prusa’s Prague factory, so the machines are not yet fully made in the United States.
The U.S. operation helps Prusa serve American buyers with less exposure to international shipping snags. Josef Prusa said the move into America was intended to put the company nearer to customers and support what he called its most important market, according to Tom’s Hardware.
At Open Sauce, Prusa’s booth described the company as the largest 3D printer manufacturer in the U.S. Tom’s Hardware added some needed scale: Prusa Research ships well over 10,000 printers a month from Prague and Wilmington combined, still far below the output of larger Chinese rivals manufacturing overseas.
What does Prusa make in Delaware?
The Wilmington plant manufactures the Original Prusa MK4S and Prusa Core One+ 3D printers, along with Prusament and the Jessie line of PLA and PETG filament, according to Tom’s Hardware. The Jessie filament line is named after former Printed Solid CEO David Randolph’s dog.
Tom’s Hardware said that during its 2025 visit to the factory, three filament lines were in place and a large unused area remained open for later expansion. The site also serves as Prusa Research’s American fulfillment center for Amazon sales and as the official U.S. service center for repairs and maintenance.
The rebrand lands while 3D printer regulation is becoming a more visible fight. Tom’s Hardware reported that several state bills seek new oversight of 3D printers to prevent firearms production. In Delaware, House Bill 399 would require so-called “blocking technology” on 3D printers.
That policy push cuts against the public identity Prusa Research has built around open source hardware and repair rights. Tom’s Hardware also noted that Prusa makes printers used by U.S. military and government customers with high security requirements.
The corporate rename follows leadership changes at Printed Solid. David Randolph stepped down as CEO in February, and Chris Pelesky, the company’s chief sales and marketing officer, left earlier this month, according to Tom’s Hardware. Randolph has since joined Cocoa Press, while Pelesky continues to lead 3D Printopia, a consumer-focused 3D printing expo scheduled for this fall in Philadelphia.
