The UltiMaker Factor 4 Plus Upgrade Kit turns the Factor 4 you already own into a Factor 4 Plus. The upgrade is about speed: UltiMaker rates the Factor 4 Plus at up to 2× the print speed of a standard Factor 4, across all materials including composites, with no loss of dimensional accuracy. The kit combines a new vibration-absorbing gantry, high-flow AA+ and CC+ print cores and firmware that runs UltiMaker's Cheetah motion planner. It also includes a permanent license for UltiMaker TRACE, which logs and validates every print.
The build volume stays the same (330 × 240 × 300 mm), and so does everything else you rely on: the heated chamber, the material handling, Digital Factory and your existing print cores.
| Factor 4 | After the upgrade (Factor 4 Plus) | |
|---|---|---|
| Print speed | Standard | Up to 2× faster |
| Gantry | Original XY gantry | Re-engineered gantry built to absorb vibration at high speed |
| Motion planning | Standard | Cheetah motion planner removes abrupt motion changes that cause vibration |
| Print cores | Standard AA, BB, CC and HT cores | High-flow AA+ 0.4 mm (2×) and CC+ 0.6 mm (1×) included; standard cores still work |
| Process validation | Not included (Print Process Reporting sold separately) | Permanent UltiMaker TRACE license included |
| Build volume | 330 × 240 × 300 mm | Unchanged |
| Digital Factory | Connected | Stays connected; the printer updates to Factor 4 Plus automatically |

The new XY gantry module is the most important part of the kit. Printing fast shakes a machine, and vibration is what costs accuracy, so the gantry is built to absorb it. The included firmware adds the Cheetah motion planner, which takes out the abrupt changes in motion that cause vibration in the first place. Together they let the printer move much faster while holding its dimensional accuracy.
With three cores you can run two high-flow cores, or one high-flow core next to a dedicated BB support core. You only get the full speed increase with AA+ or CC+ cores installed.
UltiMaker TRACE (Technical Reporting And Certification Engine) continuously measures four key factors of every print: extrusion factor, nozzle temperature, build-volume temperature and build-plate temperature. It flags small thermal or volumetric deviations that could affect part quality, layer adhesion or mechanical performance, and it produces a digital report for each job. That makes it useful for the documentation that production, aerospace and defense work require. The license is permanent. You activate it through an UltiMaker account, but the printer itself doesn't have to be networked or added to Digital Factory.

Nothing will impact your 3D printing results like the kind of filament you use. Good filament is highly consistent in diameter, is wound evenly onto the spool with just the right amount of tension, and will not tangle when being unwound. 3D Universe offers a wide range of high-quality filaments to choose from.
