Ultimaker S6 Secure is a variant of the Ultimaker S6.
This means it shares many characteristics with the base model but may have specific modifications, additional features, or bundled accessories.
Connect the Ultimaker S6 Secure to SimplyPrint
Does the Ultimaker S6 Secure 3D printer work with SimplyPrint, OctoPrint, Mainsail and Fluidd?
Each way of connecting it, what it needs, and how to set it up.
SimplyPrint Client
Not expected to work
Built to run air-gapped: no Wi-Fi, no cameras, USB-only workflows, tamper-resistant firmware. (The Secure page also mentions Digital Factory over a local network; even so, the S6 firmware is not a Client integration.)
Source
Ships UltiMaker's own closed firmware; no Klipper, and no known route to install it.

No known way to connect it to SimplyPrint
Unfortunately, the Ultimaker S6 Secure is currently not, to our knowledge, compatible with OctoPrint, Mainsail, Fluidd, or SimplyPrint. For the best 3D printing experience, consider other 3D printers that are compatible with these softwares.
How we determine compatibility
We consider a printer compatible if it works with one or more of the following:
SimplyPrint custom integration for this specific model
OctoPrint support (requires the printer to support serial printing)
Klipper support (printer can run Klipper, either by flashing compatible firmware or using an external controller/pad)
OctoPrint compatibility is primarily based on whether the printer supports serial communication. If serial printing is not supported, we mark OctoPrint as not compatible.
Note: Some printers have third-party OctoPrint plugins that enable unofficial/custom connections. We don’t maintain a list of these plugins, so they are not reflected in our compatibility data.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Ultimaker S6 Secure.

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.

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:ultimaker.com
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 ●●●●●
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.
[1][2]
Local control and integrations ●●●●●
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.
[3][12]
Third-party filament, slicers and parts ●●●●●
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.
[2][4]
Repairs and spare parts ●●●●●
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.
[5]
Data and privacy ●●●●●
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.
[6][3]
Community and documentation ●●●●●
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.
[2][3]
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.
[7]
February 2026: UltiMaker sold the Thingiverse model platform to MyMiniFactory and archived its Thingiverse forum.
[8]
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.
[9]
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.
