UltiMaker launches Factor 4 Plus with faster printing, part validation

That proof comes from TRACE, short for Technical Reporting And Certification Engine. UltiMaker built the system into the Factor Series firmware so every print job is automatically validated and turned into a digital report. The company says the report can be ready within 15 minutes of job completion and exported as a PDF, giving operators a record of extrusion factor, nozzle temperature, chamber temperature, and build plate temperature. UltiMaker’s reporting materials also say the file can show where deviations happened in the model and how severe they were, which is exactly the kind of traceability industrial buyers keep asking for.

For advanced home shops and small production setups, the more interesting story is where these features point next. UltiMaker paired the Factor 4 Plus with its Cheetah motion planner, first introduced on April 8, 2025, which is designed to eliminate speed jumps and use input shaping and pressure advance to improve speed, visual quality, and dimensional accuracy. UltiMaker said the S8 with Cheetah reaches 0.15 mm ± 0.15% print quality, a useful reminder that the same motion tuning that helps industrial throughput also shapes how clean a machine feels on the bench.

The hardware package follows the same logic. The Factor 4 Plus uses a triple-insulated build chamber, direct dual extrusion, an actively temperature-controlled build volume up to 70 C, and a heated bed up to 120 C. UltiMaker says the gantry was lifetime-tested for 15,000 hours, and the machine supports automatic material handling with up to six spool switches while staying below 15% relative humidity. Those are the kinds of robustness and workflow features that often start in industrial systems before they migrate into more prosumer-friendly printers.
