What's Changed

This is the OrcaSlicer V2.4.0 Alpha release. The headline feature is Orca Cloud — a new centralized platform for profile sync, preset bundle sharing, and community discovery at cloud.orcaslicer.com. This release also introduces Z Anti-Aliasing (ZAA) contouring for smoother top surfaces, an Expert user mode, native Wayland support for Linux, Machine Input Shaping, Optimized Gyroid infill, Prusa-style combined brims, a redesigned printer selection dialog, and a large number of bug fixes and profile updates.

Note: Please check #13828 for known issues.

☁️ Orca Cloud

Orca Cloud is now live at cloud.orcaslicer.com ↗ — a centralized platform that brings your 3D printing workflow online.

It keeps your printer, filament, and process profiles synchronized across every machine you use, lets you share finely tuned preset bundles with the community, and helps you discover configurations created by fellow makers around the world.

Think of it as the connective tissue between your slicer, your profiles, and the broader OrcaSlicer ecosystem — no more manually copying config files between computers or hunting through forums for the right profile.

Note: Orca Cloud is optional. Local profiles and existing OrcaSlicer workflows continue to work as before. You can keep using OrcaSlicer without logging in to Orca Cloud.

Open ecosystem: Orca Cloud is part of our long-term vision for an open 3D printing ecosystem. We want OrcaSlicer to connect users, contributors, printer manufacturers, filament makers, and hardware/software partners through shared profiles, better compatibility data, and smoother workflows. We welcome users, makers, manufacturers, and partners to join, integrate, and collaborate with us to build an ecosystem that benefits the whole community and the wider 3D printing industry.

This is just the beginning. We have many more features planned for Orca Cloud and the broader OrcaSlicer ecosystem.

Orca Cloud is designed with privacy in mind. Data is currently hosted in the USA. In the future, we plan to add more region-specific servers and allow users to choose their preferred data center location for improved performance, data residency, and privacy needs.

Profile Sync: Log in to OrcaSlicer with your Orca Cloud account, and your printer, filament, and process profiles sync automatically across machines. You can also view and manage all synced profiles from the Orca Cloud web interface.

Orca Cloud profile sync interface

Profile Version History: Your cloud-backed profiles support version history on Orca Cloud. Mark milestones, track what changed, and revert to a previous version whenever you need — useful for recovering from a tuning session that did not work out, or rolling back to a known-good configuration before an important print.

Orca Cloud profile version history

Preset Bundles: Create shareable preset bundles with descriptions, images, version info, and compatible printer metadata. Publish them publicly for the community to discover, or keep them private and share only with specific collaborators.

Orca Cloud preset bundle editor

Community Explore: Browse public bundles shared by the community on the Orca Cloud website. Subscribe to bundles you like and they will sync to your slicer automatically, with update notifications when the author publishes a new version.
