The S6 and S8 run a different firmware that UltiMaker says is not compatible with the S3/S5/S7's; whether its local API is the same is unconfirmed. ([Source](https://support.ultimaker.com/s/article/s6-s8-firmware)) | | OctoPrint (Directly, over USB) | Not expected to work | | UltiMaker S-line printers take jobs over the network or from a USB drive; no USB serial printing is documented (the S7's manual shows a host port only). ([Source](https://ultimaker.com/3d-printers/s-series/ultimaker-s6/)) | | Klipper (Moonraker) | Not compatible | | Ships UltiMaker's own closed firmware; no Klipper, and no known route to install it.

Filament compatibility for the Ultimaker S6: the materials Ultimaker lists for it. | Filament | Suitability | Notes | | :--- | :--- | :--- | | PLA | Great | On the maker's list of materials for this printer. | | PETG | Great | On the maker's list of materials for this printer. | | TPU & flexibles | Great | On the maker's list of materials for this printer. | | ABS & ASA | Great | On the maker's list of materials for this printer. | | Nylon (PA) | Great | On the maker's list of materials for this printer. | | Polycarbonate (PC) | Great | On the maker's list of materials for this printer. | | Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. | ## When to choose the Ultimaker S6 Choose the S6 when you want UltiMaker's ecosystem (Cura, Digital Factory, 301+ materials) at the lower end of the S series and can live with a partly enclosed chamber. The UltiMaker S8 is the step up if you want the fully enclosed build chamber and an integrated EPA filter; the S6 only has an optional Air Manager. We cannot yet connect it to SimplyPrint, so check that matters to you first. ### Pros - Dual extrusion with swappable print cores, and 301+ compatible materials including optional composite and metal cores (UltiMaker). - Up to 500 mm/s travel speed and 50,000 mm/s2 acceleration from the Cheetah motion planner (UltiMaker). - Flexible PEI-coated steel plate that releases parts easily, with an optional glass plate (UltiMaker). - Works with the Material Station for longer unattended runs and the optional Air Manager with an EPA filter (UltiMaker). - 12-month warranty and Wi-Fi, Ethernet and USB connections (UltiMaker). ### Cons - No confirmed way to connect it to SimplyPrint: Klipper is not possible and OctoPrint is unlikely, and our SimplyPrint Client status is unknown. - Only partly enclosed and passively heated, so ABS and nylon are not as well served as on a fully enclosed printer; the filter is an optional extra. - Wi-Fi is 2.4 GHz only (UltiMaker). - No independent hands-on review found for the S6 itself; claims are UltiMaker's own. ### Who it suits - Schools: Good fit. Easy to run and well supported with a warranty; the partly open chamber and the lack of a confirmed SimplyPrint connection are the drawbacks. - Hobbyists: Can work. Capable, but priced for professionals and tied to UltiMaker's ecosystem. - Businesses: Good fit. Dual extrusion, many materials and a warranty suit prototyping and tooling work. - Print farms: Can work. The Material Station allows longer unattended runs, but we cannot yet connect it to SimplyPrint. ## Printers like the Ultimaker S6 that work with SimplyPrint - [Ultimaker S7 Pro](https://simplyprint.io/compatibility/ultimaker-s7-pro): Compatible, 330 x 240 x 300 mm, Also by Ultimaker · Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) - [Creality K3](https://simplyprint.io/compatibility/creality-k3): Expected to work, 260 x 260 x 260 mm, Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) - [Rat Rig V-Core 4.1](https://simplyprint.io/compatibility/rat-rig-v-core-4-1): Compatible, 300 x 300 x 300 mm, Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) - [Bambu Lab P1S](https://simplyprint.io/compatibility/bambu-lab-p1s): Verified by SimplyPrint, 256 x 256 x 256 mm, Similar build volume · Also prints ABS & ASA, Nylon (PA), Polycarbonate (PC) ## Where to buy the Ultimaker S6 - [Ultimaker for the US](https://simplyprint.io/buy/8391) (Official store) ## About Ultimaker UltiMaker is the company formed in 2022 when the Dutch printer maker Ultimaker, founded in 2011, merged with MakerBot. It sells professional desktop and industrial printers (the S series, Factor 4, MakerBot Method and Sketch) to businesses, engineering teams and schools, and develops the open-source Cura slicer and the Digital Factory cloud platform. - Founded: 2011 - Headquarters: Zaltbommel, Netherlands, and New York, USA - Ownership: Privately held; at the 2022 merger NPM Capital held the majority and Stratasys a minority stake - Website: https://ultimaker.com Openness: Mixed (2.9 of 5) UltiMaker is mixed: Cura and material choice are open, and printers can be used on the local network, but the printer firmware is closed and most management features sit in its Digital Factory cloud. - Firmware and custom firmware (2 of 5): The printers' own software is not published: UltiMaker's GitHub has its Linux kernel configuration and Cura, but no printer firmware. We found no documented way to run custom firmware on current S-series or Method printers. - Local control and integrations (3 of 5): Cura can add an S-series printer on the local network, by discovery or IP, without signing in, and start prints. UltiMaker says most features are only available through its Digital Factory cloud, and the API it documents publicly is that cloud API; we found no public documentation for controlling the printers locally. - Third-party filament, slicers and parts (3 of 5): Cura is open source and widely used with other brands, and UltiMaker lists over 300 materials, including third-party ones, for the S series. Print cores and the Material Station are UltiMaker's own parts. - Repairs and spare parts (3 of 5): UltiMaker publishes maintenance schedules for the S series and sells part bundles and maintenance kits, and gives an expected printer lifetime of five years at 1,500 printing hours a year. - Data and privacy (4 of 5): Local printing needs no account; Digital Factory needs one. UltiMaker's privacy policy says data is stored and processed in the EEA or the United States depending on the user's region. - Community and documentation (4 of 5): Cura is developed in public on GitHub with a large open issue tracker, and UltiMaker runs a community forum and support knowledge base. Printer internals are not documented publicly. ### Pros - Cura is open source and works with printers from many brands. - Wide material choice on the S series, including third-party materials. - Printers can be used on the local network without an account. - Published maintenance schedules and maintenance kits for long service life. ### Cons - Printer firmware is closed. - Most fleet and management features need the Digital Factory cloud, with paid tiers. - MakerBot CloudPrint was shut down in 2025, forcing users to move platforms. - Print cores and the Material Station are UltiMaker-only parts. ### Track record - May 21, 2026: UltiMaker launched the Factor 4 Plus, an industrial printer up to twice as fast as the Factor 4, with TRACE print validation for production and defence customers. - February 2026: UltiMaker sold the Thingiverse model platform to MyMiniFactory and archived its Thingiverse forum. - December 2025: UltiMaker shut down MakerBot CloudPrint in early December 2025. Users had to reconnect printers to Digital Factory, with a free year of its premium tier offered to former CloudPrint users; the Replicator+ cannot be networked in Digital Factory. - May 2022: Ultimaker and Stratasys' MakerBot announced a merger backed by $62.4 million from NPM Capital and Stratasys, with co-CEOs from both companies and headquarters in the Netherlands and New York. The combined company took the UltiMaker name.
