Printed Solid, a Delaware filament manufacturer acquired by Czech Prusa Research in 2022, is now operating as Prusa USA, Inc., with CEO Josef Prusa continuing to lead both companies. The name change was announced at the Open Sauce conference and described by Prusa Research representatives as largely symbolic, with no change to daily operations. The company runs a 100,000‑square‑foot facility in Wilmington that produces Original Prusa MK4S and Prusa CORE One+ 3D printers, Prusament filament, and the Jessie line of PLA and PETG. While the printers are assembled in the United States, certain parts are sourced from Prusa’s factory in Prague, a practice the company says helps mitigate supply‑chain issues for American customers. Prusa USA serves as the U.S. fulfillment center for Amazon sales and the official service center for printer repair and maintenance. Josef Prusa said, "We wanted to be closer to our customers. Expanding to America was the natural next step to support the most important market in the world." Several states have introduced legislation requiring spyware on new 3D printers to prevent firearm production, and Delaware’s House Bill 399 proposes “blocking technology” for all printers. Prusa Research has opposed these measures, citing its support for open source principles, the right to repair, and the security needs of U.S. military and government agencies. David Randolph, the former CEO of Printed Solid, stepped down in February, and Chris Pelesky, the chief sales and marketing officer, resigned earlier this month. Both remain active in the industry; Randolph now leads Cocoa Press, and Pelesky heads 3D Printopia, a major consumer expo scheduled for Philadelphia this fall. The rebranding occurs as additive manufacturing gains traction and regulatory proposals loom.
