Check out the OrcaSlicer 2.5.0-alpha release! Our most ambitious release so far 👇
OrcaSlicer V2.5.0 Alpha is here 🐋
This is the most feature-packed release in OrcaSlicer's history: more than 950 pull requests from over 140 contributors.
🧩 Python plugins: extend the slicer without maintaining a fork, and share your plugins on Orca Cloud
🧱 Texture Displacement: stamp real, printable 3D texture onto any surface
🎨 Color mixing: blend new colors from the filaments you already have loaded
🏭 Belt printing: conveyor "infinite Z" printers, sliced natively
👯 IDEX & IQEX parallel printing: two to four parts at once
✏️ Design tab: a parametric CAD workspace inside the slicer (early preview)
⚡ Speed Dial: press Space, run anything
Plus Tool-changing algorithm improvements, precise Seam modifiers, startup in about half the time, slicing ~35% faster, and hundreds of fixes.
It's an alpha, so some of this is experimental. Back up the projects you care about.

☁️ Reminder: since 2.4.0, OrcaSlicer syncs your profiles with Orca Cloud.
Were you using Bambu Cloud to sync? Just sign in to Orca Cloud and your profiles migrate automatically. If you didn't, nothing changes for you.

People ask me all the time where the name "OrcaSlicer" came from. The truth? One picture popped into my head — an orca using its fluke like a blade, slicing a model clean in half. Done. Named.
(Plus a nod to Slic3r, PrusaSlicer, SuperSlicer.)
@BlayneSapelli & Radu from @Snapmaker sat down with Ian, Yunus and me — origin story, going full-time, the whole thing: blog.snapmaker.com/blog/six-…

Let's continue, shall we? 🧩
OrcaSlicer 2.4.0 supercharges the Dovetail tool! You can now cut with multiple dovetails in a single operation (previously just one), with control over count and gap. Perfect for splitting large models to fit your plate and reassembling them accurately. This is all possible thanks to Xipit's work (Printables: @penguinprototypes), who also contributed other 2.4.0 improvements — like more user control over the auto-drop-to-bed feature. Check out our release notes for more: orcaslicer.com/wiki/releases…
Dovetail was originally ported from @PrusaSlicer — kudos to @josefprusa and his team! 🙌

Also for Linux users, we have significantly improved usability and stability on Linux!
OrcaSlicer V2.4.0 Beta is here 🐋
This build is all about stability, speed, and print quality — with plenty of new features along the way.

Highlight 1: Realistic View — A new realistic rendering enhancement with ambient occlusion and cast shadows makes your models look stunning right inside the slicer.

We do!
We probably undersell OrcaSlicer features too much.
Did you know OrcaSlicer supports printing with different nozzle sizes?
This feature was first introduced by @fever_soft in v2.2.0-beta back in 2024 (!!). In v2.4.0-alpha, IanAlexis fixed a regression, and now it works even better.
More enhancements are coming soon!
Pro tip: use percentages for line widths.

OrcaSlicer V2.4.0 Alpha is here 🐋
This one's packed!
Orca Cloud is the big new platform — centralized profile sync, preset bundles, and community sharing at cloud.orcaslicer.com. Your profiles on every machine, no more config-file juggling.
Z Anti-Aliasing (ZAA) brings micro-non-planar contouring for noticeably smoother curved top surfaces.
Fuzzy skin gets a Ripple mode — tunable patterned textures that finally look intentional.
Non-crossing tri-hexagon infill — stronger, more isotropic infill with no line intersections.
Plus: optimized Gyroid infill, combined brims, Machine Input Shaping, Expert user mode, native Wayland support, a redesigned printer selection dialog, and a mountain of bug fixes.
Free, open source, and better than ever.

This is what happens when you use Copilot in Outlook. Microsoft forces AI into every Office application, and this is the experience. I can't understand their company culture.
And we will ship more amazing features together with the incredible community :)
Hey everyone — a quick note from the OrcaSlicer team.
A few of you have asked whether we're connected to a recent legal notice from Bambu Lab. Just to clear things up: that notice went to the developer of a separate, independent fork — not to OrcaSlicer or anyone on our team. Forks are a normal and healthy part of open source, and we wish that developer the best. Thanks to everyone who pinged us about this — it means a lot that you cared enough to check. Back to slicing.

GitHub Copilot has been going rogue lately—it's adding itself as a co-author on every commit I make in VS Code, even if I never used it at all. I knew nothing good would come from Microsoft taking over GitHub 🤦♂️
We just raised $30M at a $500M valuation, bringing our total funding to $47M.
Led by @craft_ventures , with @PaceCap , @chemistry , TruArrow, and others.
But before anything else: this belongs to the community.
ComfyUI started as one developer and one open-source repo. No roadmap. No company. Just creators who wanted real control over how they built with AI.
That community is now:
→ 4 million users
→ 60,000+ community-built nodes
→ 150,000+ daily downloads
Every number traces back to people who built in the open, for anyone to use.
Here's where the funding goes:
→ Comfy Cloud: for teams and studios that need security and scale
→ Collaborative workflows: versioning and iteration built for how studios actually work
→ A better local experience: more seamless, more stable
→ Ecosystem reliability: making 60,000+ community nodes more dependable
→ Day-one model support: every major release, compatible at launch
We are not building a walled garden.
We are building open infrastructure, built to last.
Thank you genuinely,
The ComfyUI Team
A big shout out to @QIDI_3dprinter and @BigTreeTech for their genuine and consistent support of the OrcaSlicer project. Kudos to both teams. Their support has meant a lot to both the project and the community.
As of today, they are the only two companies sponsoring OrcaSlicer through recurring monthly donations. We hope more companies that have benefited from OrcaSlicer’s work will also contribute back. Donations help our volunteer open-source contributors buy machines, materials, and other resources needed to keep the project moving forward.
