Hey everyone,
The past few months have been some of the most exciting we’ve seen in the U1 community. What started as a few experimental posts about full‑color printing has snowballed into a great movement, and we want to take a moment to: say thank you, share some news, and tell you what’s coming next.
- Thank you!
Full Spectrum didn’t come from a roadmap meeting. It came from you.
It started with u/Rob_Bob_you_choose, who showed the world that the U1’s four toolheads could be coaxed into 9‑color prints from just 4 filaments — a wild proof of concept that lit the spark.
Then u/Aceman11100 posted his approach to near‑full‑color printing on the U1 using just three base filaments and layer‑alternating color mixing.
Within hours, u/beybladetable (Radu, “Ratdoux”) had forked Snapmaker Orca and shared a working prototype: Snapmaker Orca FullSpectrum, a Snapmaker Orca fork with mixed-color filament support. Hours. From idea to working tool!
Then @WombleyWonders stepped up and made the deep‑dive video that introduced Full Spectrum to a much wider audience — explaining the theory, showing the limits, and helping new users actually understand what they were looking at.
And honestly, that’s still just the visible tip. A huge group of contributors on our Discord and GitHub have been quietly making Full Spectrum better:
-
wildtang3nt (Discord) — testing and coding for improved color prediction
-
Hunter Cook (@jusdisgi on Reddit/GitHub) — process testing, advice, and improvement reporting
-
Silent (@xSil3nt on GitHub) — early UI development
-
cheeky_b52 (Discord) — print & filament testing and improvement reporting
-
neotko (Discord & GitHub) — top‑surface blending feature development
-
Xipit (Discord) — UI redesign currently in development
-
북리지 (@bookledge) (YouTube) — print testing, improvement reporting, and incredible creations/videos
-
YGK3D (YouTube) — influential video that helped bring Full Spectrum to a wider audience
-
Steve Lavedas (HueForge) — early development advice from someone who literally pioneered this space
…plus everyone in the Discord threads who’s been printing test palettes, posting failures, posting wins, and discussing about better UI. Thank you!
- Radu is joining Snapmaker
We’re thrilled to share that Radu (Ratdoux) — the developer behind Full Spectrum — is joining the Snapmaker team to help lead our next‑generation color‑printing work.
We reached out because it is the right thing to do, when a community member builds something this meaningful, we believe the right path is to recognize the work, bring the creator into the process, and support it with engineering, testing, and product resources.
Radu will keep doing what he’s been doing: pushing what’s possible with the U1, working openly, and listening to the community. Full Spectrum will continue to be developed openly under AGPL‑3.0.
Welcome aboard, Radu. 
- Full Spectrum is coming to official Snapmaker Orca soon
We’ve been quietly preparing this for a while: the core features of Full Spectrum are being integrated into the official Snapmaker Orca, and we plan to share a beta version with our community first, in the coming weeks.
When the beta drops, you’ll be the first to know. We’d love your feedback: bugs, feature requests, weird filament combinations, the works. The whole point is to build this with you, the same way it started.
A small note before we go:
To everyone above, to everyone we missed (sorry — please call us out so we can fix that), and to everyone who’s about to jump into Full Spectrum for the first time: thank you for making the U1 community what it is.
The Snapmaker Team
