[OrcaSlicer-FullSpectrum](https://github.com/SoftFever/OrcaSlicer-FullSpectrum) +with contributions from Rad, Justin Hayes, Calogero Guagenti, xSil3nt, and ratdoux. + +--- + +## User Guide + +### What It Does + +Mixed Filament lets a single virtual filament slot alternate between two +physical filaments across layers (or within a layer in Pointillisme mode), +producing blended or gradient-like colours on single-extruder printers. + +### Enabling + +1. Load a multi-colour (multi-extruder) profile with at least 2 filaments. +2. The **Mixed Filaments** panel appears automatically in the right-hand sidebar + when 2 or more filaments are configured. +3. Each auto-generated row represents one pair of physical filaments. + Toggle a row to enable it; the total filament count grows to include the + virtual slot. + +### Sidebar Workflow + +- **Add** — creates a custom row for the same pair or a different ratio. +- **Edit** — opens `MixedFilamentConfigPanel` to adjust ratio, pattern, + surface offset (bias), and distribution mode. +- **Delete** — marks the row deleted; existing painted geometry retains its + virtual filament ID until you re-slice or repaint. + +Painting with a virtual filament ID behaves the same as painting with a +physical one — use the Multi-Material Painting gizmo and select the virtual +slot from the colour palette. + +### Color Match Dialog + +Open via the colour swatch on a mixed row. The dialog (`MixedFilamentColorMatchDialog`) +shows a live preview strip of the blended result and lets you adjust ratio +until the preview matches your target colour. The preview accounts for +surface-offset bias when enabled. + +### Anti-Banding Options + +| Setting | What it does | +|---|---| +| `mixed_filament_advanced_dithering` | Uses an ordered dither pattern instead of simple A-then-B runs. Reduces stripe visibility on some hue pairs. More experimental than the default. | +| `dithering_local_z_mode` | Splits each blended layer into two sub-layers whose heights are proportional to the mix ratio (e.g. 66/33 at 0.12 mm → 0.08 mm + 0.04 mm). Produces the smoothest colour gradients. | +| `dithering_local_z_whole_objects` | Extends Local-Z splitting beyond painted masks to cover the entire object cross-section. Useful when mixed walls surround a painted zone. | +| `dithering_local_z_direct_multicolor` | For rows with 3 or more physical components, allocates Local-Z sub-layers directly across all components with carry-over error correction instead of collapsing to pair cadence. More toolchanges; less banding. | + +### Gotchas + +- **Single-extruder warning** — Mixed Filament requires a physical toolchange + between the two components. On a true single-nozzle printer this means a + manual filament swap. Verify your printer profile supports `T0`/`T1` before + using mixed slots in a production print. +- **Variable-layer interaction** — If Variable Layer Height is enabled, Local-Z + sub-layer heights are recomputed per interval. The mix ratio is preserved but + the absolute sub-layer heights change with the variable height. Review the + layer preview after applying variable layers. +- **Custom sequence disabled** — OrcaSlicer's "custom toolchange sequence" is + suppressed when mixed filaments are active (`PlateSettingsDialog`). The + virtual-to-physical resolution must control toolchange order; a user-defined + sequence would break it. +- **Stable IDs** — each mixed row carries a `stable_id` (64-bit). If you + reorder or delete rows and then load an older project, the ID remap in + `PresetBundle::update_mixed_filament_id_remap` translates painted geometry + to the correct new virtual slot. Do not rely on the 1-based filament index + as a stable identifier. + +--- + +## Developer Guide + +### Core Data Structures + +``` +src/libslic3r/MixedFilament.hpp — MixedFilament struct, MixedFilamentManager +src/libslic3r/MixedFilament.cpp — serialization, resolve(), auto_generate() +src/libslic3r/LocalZOrderOptimizer.hpp — bucket-ordering helpers for Local-Z +``` + +The key scalar fields on `MixedFilament`: + +- `component_a`, `component_b` — 1-based physical filament indices. +- `ratio_a`, `ratio_b` — layer-alternation cadence numerators. +- `mix_b_percent` — nominal colour mix (used for Local-Z height computation + and the Color Match preview; does not change the cadence). +- `stable_id` — monotonically increasing 64-bit ID assigned at construction. + Never reused. Survives serialization round-trips. +- `distribution_mode` — selects between `Simple`, `SameLayerPointillisme`, + and `GroupedManual`. + +### Seam: Adding New Distribution Modes + +`MixedFilamentManager::resolve()` in `MixedFilament.cpp` is the single +dispatch point that maps `(virtual_filament_id, num_physical, layer_index)` +to a physical extruder. The current switch covers `Simple` and +`SameLayerPointillisme`. A new mode is added by: + +1. Adding a value to the `MixedFilament::DistributionMode` enum in + `MixedFilament.hpp`. +2. Adding a `case` to `MixedFilamentManager::resolve()` in `MixedFilament.cpp`. +3. Serializing the new mode token in `serialize_custom_entries` / + `load_custom_entries` (format is a semicolon-delimited row string; see + existing tokens for the convention). + +G-code emission (`src/libslic3r/GCode/`) reads only the physical ID returned +by `resolve()`, so new modes are automatically emitted without further changes. + +### Seam: New Toolchange-Cost Heuristics + +`LocalZOrderOptimizer` (`src/libslic3r/LocalZOrderOptimizer.hpp`) exposes: + +- `order_bucket_extruders(bucket, current, preferred_last)` — reorders a + single-layer bucket to minimise toolchanges given the current active extruder. +- `order_pass_group(group, current_extruder)` — greedy walk across a set of + buckets (one per Local-Z sub-layer) to minimise total transitions. + +To add a new heuristic (e.g. cost-based look-ahead), replace or wrap +`order_pass_group`. The caller in `PrintObjectSlice.cpp` passes the result +directly into the sub-layer plan, so the heuristic is fully decoupled from +the plan builder. + +### Seam: New Picker Shapes in the Color Map Panel + +`MixedFilamentColorMapPanel` (`src/slic3r/GUI/MixedFilamentColorMapPanel.hpp`) +renders a 2-D colour map using a set of geometry "types" (currently strip and +gradient). Each type is a small self-contained rendering path keyed by an enum +value. New shapes are added by: + +1. Adding an enum value to `MixedFilamentColorMapPanel::GeometryType`. +2. Implementing the corresponding `Paint*` helper (follow `PaintStrip` as a + template). +3. Wiring the new type into the `switch` in `OnPaint`. + +### Persistence (3MF) + +The entire mixed-filament state is stored as a single string key +`mixed_filament_definitions` in the project config block (section `[presets]` +in the 3MF metadata). + +Round-trip path: + +``` +MixedFilamentManager::serialize_custom_entries() + called by PresetBundle::sync_mixed_filaments_to_config() + written by bbs_3mf: store_bbs_3mf → config.set("presets", "mixed_filament_definitions", ...) + +load_bbs_3mf → config.get("presets", "mixed_filament_definitions") + stored in project_config["mixed_filament_definitions"] + read by PresetBundle::sync_mixed_filaments_from_config() + → mixed_filaments.auto_generate(colours) + → mixed_filaments.load_custom_entries(defs, colours) +``` + +Auto-generated rows are *not* written to the definitions string; they are +rebuilt from the filament colour list. Only `custom == true` rows are stored. + +See `tests/fff_print/test_mixed_filament_e2e.cpp` for regression tests +covering this path. + +### ID Remap + +When filaments are added, removed, or reordered, virtual IDs shift. +`PresetBundle::update_mixed_filament_id_remap(old_mixed, old_count, new_count)` +produces a `remap` vector where `remap[old_virtual_id] = new_virtual_id`. +Painted triangle mesh face data uses these IDs; the remap is applied in +`TriangleSelectorMixed` after any filament list change. diff --git a/localization/i18n/list.txt b/localization/i18n/list.txt index a3fb0e995c..4591263363 100644 --- a/localization/i18n/list.txt +++ b/localization/i18n/list.txt @@ -249,3 +249,7 @@ src/slic3r/GUI/RammingChart.cpp src/slic3r/GUI/StepMeshDialog.cpp src/slic3r/GUI/FilamentPickerDialog.hpp src/libslic3r/PresetBundle.cpp +src/slic3r/GUI/MixedFilamentColorMatchDialog.cpp +src/slic3r/GUI/MixedFilamentColorMatchDialog.hpp +src/slic3r/GUI/MixedFilamentConfigPanel.cpp +src/slic3r/GUI/MixedFilamentConfigPanel.hpp diff --git a/src/libslic3r/AppConfig.cpp b/src/libslic3r/AppConfig.cpp index 6da825b090..0baa141002 100644 --- a/src/libslic3r/AppConfig.cpp +++ b/src/libslic3r/AppConfig.cpp @@ -371,6 +371,10 @@ void AppConfig::set_defaults() set("auto_calculate_flush","all");
