UltiMaker S6 Flex 3D printer for faster dual-material production

The UltiMaker S6 Flex is a dual-extrusion 3D printer built on the award-winning S5 legacy and updated for higher throughput, easier operation, and better day-to-day usability. It delivers up to 4x productivity with the UltiMaker Cheetah motion planner, improved bed levelling, and a flexible build plate included in the box.

S5 versatility with higher speed and easier access

This 3D printer combines the proven versatility of the S5 platform with S8-level speed and improved accessibility. The result is a more efficient system for users who need dependable output across a wide range of materials and applications.

Features that improve print speed, handling, and reliability

UltiMaker Cheetah motion planner for higher productivity

The UltiMaker Cheetah motion planner is designed to unlock new levels of efficiency. It works alongside redesigned high flow print cores, a built-in accelerometer, a new feeder system, and improved firmware to increase throughput while supporting cleaner, more controlled printing.

Digital Factory for slicing, file management, and maintenance

Digital Factory is the workflow platform for managing every step of 3D printing, from slicing and file management to maintenance. The system is built to scale from individual users to teams and enterprise environments, making collaboration and printer management more streamlined.

Flexible PEI build plate for faster turnaround

The included PEI-coated flexible build plate helps reduce preparation and part removal time. Users can skip glue and remove parts more easily, while the patent-pending design uses 25 magnets and 4 pins to maintain precise alignment and reduce time spent handling the printer.

Dual extrusion for combining different materials

The dual extrusion system works with UltiMaker software and firmware features to combine any two materials no matter how different they are. That approach supports low material waste and high reliability in multi-material printing workflows.

High flow print cores for cleaner prints at higher throughput

The AA+ and CC+ print cores developed for the UltiMaker S6 use a new quad-chamber design. These high flow print cores provide 2.5x more flow and help regulate pressure in the print head for cleaner printed results.

Material Station compatibility for unattended printing

Backwards compatibility with the Material Station supports longer unattended print jobs during day or night operation. Material loading takes seconds rather than minutes, helping reduce interruptions in production workflows.

Cura integration for a smoother workflow

UltiMaker Cura integration adds workflow tools that help improve print success and reduce setup time. Supported features include intent profiles, easy remote printing, and other tools designed to speed up job preparation and management.

Updated feeder system for high-speed material control

The updated hardened feeder module design is inherited from Factor 4. It improves grip and provides better material control at high speeds, helping the printer maintain consistency during faster operation.

Reliability backed by a 24-month warranty

The UltiMaker S6 Flex is positioned for dependable long-term use with bulletproof reliability and a 24-month UltiMaker warranty. This combination supports users who need predictable output and lower supervision in regular production work.

Optional Air Manager for cleaner enclosed printing

An optional Air Manager with EPA filter is available for users who want improved air handling. It has been independently tested to remove up to 95% of ultrafine particles, while the fully enclosed build chamber also helps boost print quality.

Where the UltiMaker S6 Flex fits best

The UltiMaker S6 Flex suits makers, educators, engineers, product designers, and small production environments that need faster output without giving up material flexibility. The dual-material system, high flow print cores, unattended printing compatibility, and workflow software make the printer well suited to prototypes, fixtures, functional parts, classroom use, and managed multi-user environments.
