Cache load is now all-or-nothing: on hit all vendors are applied from the bundle (sub-second); on miss all vendors are parsed from JSON and a fresh bundle is written to the user cache dir. Invalidation is driven by bundle_key - a sorted concatenation of all vendor JSON version strings. Any vendor update invalidates the whole cache and triggers re-parse on next launch. Guide wizard (WebGuideDialog) loads the bundled cache into a plain PresetBundle instead of a separate VendorGuideData struct, removing the duplicate data model. generate_system_cache simplified from a per-vendor loop to a single save_system_presets_cache() call producing one output file. * Transfer all Preset fields from cache via move assignmet apply_vendor_preset_group was copying fields manually and missed bundle_id, user_id, base_id, sync_info, updated_time, key_values, ini_str. Replace field-by-field copy with move assignment of the fully-deserialized Preset, then restore the vendor pointer which is excluded from serialization. * Ignore cache for future * Remove not used files * Ship one preset cache per vendor in place of the profile JSONs Each vendor's system presets serialize into a single <vendor>.opc built at package time, and a shipped build carries that file alone — the profile JSON and its sub-file tree are pruned. The vendor loader, the setup wizard's profile list and the resource installer all read a vendor through its cache, falling back to parsing whenever one is absent, stale or unreadable, so the cache stays an optimization and never a source of truth. Caches hold presets in source form and resolve inheritance at load, through the same code the JSON path uses. * Make the preset cache self-describing and load each vendor from the system folder alone The cached DynamicPrintConfig is keyed by name, through a per-file dictionary of the distinct opt_keys, the type each was written as, and the distinct enum value names, instead of by serialization_key_ordinal — a position assigned by declaration order at static init, where inserting one option shifts every later ordinal and the lookup then succeeds on the wrong option. Because a name-keyed payload drops the options this build cannot place rather than being rejected wholesale, the schema fingerprint goes, and with it the two fallbacks that existed only because an installed cache died on every app upgrade: the second lookup tier into resources/profiles and the parse fallback to the same place. A vendor is loaded from <data_dir>/system/ and nowhere else, as on main — which is what makes the app write its .opc files there again. * Simplify the preset cache internals after review * Use the shared temp-dir helper in the preset bundle loading test * Bound stamp string reads in the preset cache * Speed up the setup wizard with a profile-data cache The wizard's per-vendor fast path threw on vendors present only in resources, falling back to a ~29 s raw JSON scan on every open. Each vendor now loads from the directory it was found in, and the derived model/machine/filament/process catalog is cached whole in <data_dir>/cache/wizard_profile_data.json, stamped by each vendor's name and version - a fresh cache makes an open one file read, with no bundle built and no presets installed (~0.2 s vs ~2 s). * Remove debug SVG dump from a geometry test * Move the per-vendor cache file format into PresetCacheFormat * Move the vendor install helpers from PresetBundle into Utils * rename * fix flatpak * change cache version to 1 --------- Co-authored-by: SoftFever <softfeverever@gmail.com>

Nightly Builds
🌙 Download the Latest Nightly Build
Explore the latest developments in OrcaSlicer with our nightly builds. Feedback on these versions is highly appreciated.
Belt Printer Builds
The nightly release ships two parallel builds: the standard build and a belt-printer build. Both are attached to the same release — tell them apart by the filename suffix:
- Standard — no suffix (e.g.
OrcaSlicer_Windows_Installer_x64_nightly.exe) - Belt —
_beltsuffix (e.g.OrcaSlicer_Windows_Installer_x64_nightly_belt.exe)
The _belt builds add experimental support for belt / conveyor (infinite-Z) printers, where the model is sliced against a tilted belt surface instead of a flat horizontal bed. They include ready-to-use belt printer profiles, the full belt slicing pipeline (mesh rotation and G-code transforms), belt-aware support generation, and a tilted-bed preview.
⚠️ Belt printer support is under active development and is not yet merged into
main— it currently ships only in these parallel_beltbuilds, produced from thebelt-printerbranch. See tracking PR #14394 and the original documentation in #12998.

Some Background
Open-source slicing has always been built on a tradition of collaboration and attribution. Slic3r, created by Alessandro Ranellucci and the RepRap community, laid the foundation. PrusaSlicer by Prusa Research built on Slic3r and acknowledged that heritage. Bambu Studio in turn forked from PrusaSlicer, and SuperSlicer by @supermerill extended PrusaSlicer with community-driven enhancements. Each project carried the work of its predecessors forward, crediting those who came before.
OrcaSlicer began in that same spirit, drawing from BambuStudio, PrusaSlicer, and ideas inspired by CuraSlicer and SuperSlicer. But it has since grown far beyond its origins. Through relentless innovation — introducing advanced calibration tools, precise wall and seam control, tree supports, adaptive slicing, and hundreds of other features — OrcaSlicer has become the most widely used and actively developed open-source slicer in the 3D printing community. Many of its innovations have been adopted by other slicers, making it a driving force for the entire industry.
The OrcaSlicer logo was designed by community member Justin Levine.
