UltiMaker boosts S6 and S8 with faster Cheetah motion planner

UltiMaker has turned the S6 and S8 into faster workflow machines without changing their footprint, and that matters most for users who care about throughput, not just spec sheets. The new Cheetah motion planner sits at the center of the update, with UltiMaker saying the S8 can reach up to 500 mm/s and 50,000 mm/s² acceleration. In practical terms, that means quicker prototypes, shorter waits between revisions, and more reliable batch output for print farms, classrooms, design studios, and maintenance teams.

The bigger story is that this is an upgrade for owners, not a reset. UltiMaker launched the S8 on March 11, 2025, and the S6 on June 3, 2025, so both machines are still early in their life cycle. Rather than pushing users toward a new platform, UltiMaker is building on the same S-series ecosystem and saying the gains come from motion control, firmware, and the surrounding workflow. The company says the S8 delivers up to 4x productivity versus the S7, while the S6 delivers up to 4x productivity versus the S5. For users making functional parts or classroom tooling, that is the kind of jump that can change how many jobs get finished in a day.

UltiMaker also tied the speed boost to print quality, not just raw velocity. The S8 page says print quality improves to 0.15 mm ± 0.15%, and both machines use the Cheetah motion planner. The S6 is also compatible with the Air Manager and Material Station, while the S-series materials ecosystem supports 301+ materials. That combination matters for anyone running different filaments across long sessions, because faster motion is only useful if the rest of the workflow keeps up. UltiMaker sells the S8 from USD $8,999 and the S6 from USD $6,999, keeping both squarely in professional territory.

The user case is easy to see in UltiMaker’s own comments. Erwin Laiho, Sculptor and PrintShop Master at Design Factory, said the S6’s speed and reliability let students do additional rounds of prototyping, which improves product-development outcomes. UltiMaker has also leaned into higher-stakes use, releasing Secure versions of the S6 and S8 for defense and high-security environments. 3Dnatives noted that the S8 closely resembles the S7 externally, with the main changes inside firmware and electronics, and that lines up with the way UltiMaker is selling this platform: not as a flashy redesign, but as a steadily sharper production tool that makes existing workflows faster and harder to break.
