Printed Solid, the Delaware-based filament manufacturer acquired by Czech Prusa Research in 2022, is now known as Prusa USA, Inc. I spoke with Prusa Research team members at Open Sauce, who confirmed the name change was largely window dressing, with no changes to the company’s day-to-day operations. Josef Prusa will remain CEO of both companies, and a new Marketing Officer has been promoted internally.

During the transition, Printed Solid will be referred to as “Printed Solid, a Prusa Company.” The website now describes Prusa Research as a “European-American” company with U.S. production capabilities. The company operates a duplicate print farm at its 100,000-square-foot Delaware factory for manufacturing 3D printers and filament. The printers are not yet fully “Made in the USA,” as some parts are still sourced from the factory in Prague. This arrangement helps overcome supply chain challenges for American customers.

Expanding to Serve the U.S. Market

Josef Prusa stated: “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.”

At Open Sauce, Prusa’s booth proclaimed the company to be the biggest 3D printer manufacturer in the USA. While Prusa Research ships well over 10,000 printers per month from both Prague and Wilmington, this volume remains a fraction of what its Chinese competitors produce overseas. The 3D printing industry continues to grow as more businesses and individual makers discover the ease of additive manufacturing.

Regulatory Challenges and Open Source Commitment

The rebranding comes at a difficult time for 3D printing enthusiasts, as several anti-3D printing bills are emerging across the country. These bills seek to impose government oversight by installing spyware on new 3D printers to prevent the manufacturing of firearms. This approach stands in opposition to Prusa Research’s values, which firmly support Open Source, the right to repair, and the production of 3D printers that meet the high security needs of the U.S. military and government agencies.

Delaware, Prusa Research’s new home, has introduced House Bill 399, which would require so-called “blocking technology” on all 3D printers.

Wilmington Facility Operations

The Wilmington, Delaware facility manufactures the Original Prusa MK4S and Prusa CORE One+ 3D printers, along with Prusament and the Jessie line of PLA and PETG (named after Randolph’s dog). When we toured the facility in 2025, only three filament production lines were operational, with significant space reserved for future expansion.

The facility also serves as:

• The American fulfillment center for Prusa Research’s Amazon sales
• The official U.S. Service Center for printer support, including repair and maintenance

Leadership Changes

The corporate restructuring follows major leadership changes at Printed Solid:

• David Randolph, former CEO of Printed Solid, stepped down in February
• Chris Pelesky, Chief Sales and Marketing Officer, stepped down earlier this month

Both veterans remain active in 3D printing:

• Randolph has taken the helm at Cocoa Press
• Pelesky continues to lead 3D Printopia, one of the largest consumer-focused 3D printing expos, set to take place this fall in Philadelphia
