Printed Solid, acquired by Prusa Research, rebrands to Prusa USA

Printed Solid, the Delaware-based filament manufacturer acquired by Czech Prusa Research in 2022, is now known as Prusa USA, Inc. I chatted with Prusa Research team members at Open Sauce, who confirmed the name change was largely window dressing, with nothing changing in the company’s day-to-day operation. Josef Prusa will remain CEO of both companies, with a new Marketing Officer moving up the ranks internally.

During the changeover, Printed Solid will be known as "Printed Solid, a Prusa Company." The website now proudly states that Prusa Research is 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 the production of 3D printers and filament. The printers are not yet fully "Made in the USA," as some parts are still needed from the factory in Prague. This helps overcome supply chain issues for American customers.

Expanding to the U.S. Market

Josef Prusa states, "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." His booth at Open Sauce proclaimed Prusa to be the biggest 3D printer manufacturer in the USA. Though Prusa Research ships well over 10,000 printers a month from both Prague and Wilmington, it's a fraction of what its Chinese competitors produce overseas. 3D printing is simply getting bigger as more businesses and individual makers discover the ease of additive manufacturing.

Regulatory Challenges and Open Source Commitment

The change comes at a difficult time for 3D printing enthusiasts, as several anti-3D printing bills are sprouting up around the country. These bills aim to impose government oversight by installing spyware on new 3D printers to prevent the machines from manufacturing firearms. This is the antithesis of Prusa Research, which stands firmly on the side of Open Source, the right to repair, and proudly produces 3D printers that meet the high security needs of the U.S. military and government agencies. Delaware, Prusa Research's new home away from home, has just introduced House Bill 399, which would place so-called "blocking technology" on all 3D printers.

Wilmington Facility and Product Lines

The Wilmington, Delaware facility manufactures:

• Original Prusa MK4S 3D printers
• Prusa CORE One+ 3D printers
• Prusament filament
• Jessie line of PLA and PETG (named after Randolph's dog)

When we toured the facility in 2025, only three filament lines were established, with a massive space left clear for future expansion.

It is also the American fulfillment center for Prusa Research's Amazon sales and the official U.S. Service Center for printer support, which includes repair and maintenance.

Leadership Changes

The corporate restructuring follows some major leadership changes at Printed Solid:

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

Both veterans are still deeply involved in 3D printing, with Randolph taking the reins at Cocoa Press and Pelesky still leading 3D Printopia, one of the biggest consumer-focused 3D printing expos set to take place this fall in Philadelphia.
