🌊 New Features & Improvements

Printing / Slicing

Fine-tune flow rate for each print feature separately by @valerii-bokhan in #10641
You can now adjust the flow rate independently for different parts of your print — first layer, outer walls, inner walls, overhangs, infill, gap fill, supports, and support interfaces. This is especially helpful for eliminating the "wrinkle effect" on outer walls when printing with very thin layers, without having to raise the temperature for the entire print.
Brim now follows Elephant Foot Compensation outline by @kisslorand in #11760
A new option that generates the brim based on the adjusted first-layer shape after Elephant Foot Compensation (EFC) is applied. Without this, when EFC significantly reshapes the first layer, the brim may not actually touch the print — reducing bed adhesion. Enabling this option keeps the brim properly aligned with the adjusted first layer. Disabled by default; existing profiles are unaffected.

EFC brim disabled EFC brim enabled
Ironing angle improvements by @ansonl in #11195, #10841
Two improvements to ironing direction: a new "Fixed Ironing Angle" option keeps the ironing direction the same on every layer, eliminating the visible "tiger-striping" pattern on ironed surfaces. Additionally, the ironing angle setting is now a relative offset from the top surface fill direction rather than an absolute angle, making it more intuitive regardless of how infill rotation is configured.
Higher bridge density for better bridge surfaces by @MakeSometh1ngWonderful in #11283
The maximum bridge density can now exceed 100%, allowing tighter spacing between bridge lines for better bonding and less sagging. Use lower flow rates with higher density for smoother bridge surfaces.

Before After
Smoother spiral Z-hop on slower printers by @kisslorand in #11556
Spiral Z-hop now adapts the number of movement segments (4–24) based on your slicing resolution, instead of always using 24. This reduces the processing load on printer boards, preventing communication issues on some budget controller boards.
Limit shrinkage compensation to 90–110% by @ianalexis in #10930
Shrinkage compensation values are now limited to a 90–110% range, preventing issues from accidentally entering extreme values — no common printing material shrinks more than 10%.
Much smoother multiline infill paths by @RF47 in #11435
A major quality improvement to multiline infill patterns. All multiline logic has been rebuilt for smoother, continuous extrusion with round corner transitions, no overlap issues, and clean intersections. The maximum multiline count has been increased to 10. Supported patterns include Triangles, Cubic, Adaptive Cubic, Quarter Cubic, Archimedean Chords, Concentric, Hilbert Curve, Octagram Spiral, Support Cubic, and Tri-Hexagon.
Multiline infill now connects to walls instead of floating by @RF47 in #11765
Multiline infill lines now connect to the perimeter walls instead of to each other, greatly improving the strength of lightweight infill patterns like Lightning without affecting cubic/adaptive patterns.

Before After
Smoother flow adjustments in small areas by @ianalexis in #11716
The small area flow compensation now uses an improved curve calculation that prevents spike artifacts when values are closely spaced, and adds visible error reporting instead of silently failing.

Before (spike artifact) After (smooth)
Fixed crashes and visual errors with multiline infill at high densities by @RF47 in #10967
Prevents crashes when density × line count exceeds 100%, fixes the settings UI, and properly trims infill at wall boundaries.

Before After
Smoother surface finish at seam transitions by @kisslorand in #10722
OrcaSlicer now automatically slows down very short travel moves right before outer walls, using the outer wall acceleration and jerk values. This prevents fast travel movements from causing vibrations and surface marks at seam points — no configuration needed.
Better filling of narrow areas on solid surfaces by @kisslorand in #12107
When using non-linear solid infill patterns (honeycomb, grid, etc.), narrow strips near walls could be left unfilled. These areas are now properly detected and filled, ensuring complete coverage of internal solid surfaces.

Before After
Auto-slice: automatic re-slicing when you change settings by @ianalexis in #11407
OrcaSlicer can now automatically re-slice whenever you change a setting, with a configurable delay so rapid edits are grouped together. If you make another change while slicing is in progress, it cancels and restarts with the latest values.

Multi-Material

Per-filament ironing settings by @ianalexis in #11194
You can now set ironing parameters (flow rate, spacing, inset, and speed) per filament instead of only per process profile. Different materials often need different ironing settings — for example, PETG typically requires higher flow and wider spacing than PLA. These overrides apply automatically when you switch filaments.
Cleaner filament remapping dialog by @tome9111991 in #12016
The filament remapping dialog now shows only the filaments actually used in your project (instead of every configured slot), with color previews for easier identification.

Before After
Higher purge volume limit for high-flow hotends by @igiannakas in #11778
The purge volume cap has been raised from 900mm³ to 20,000mm³ for non-Bambu printers with high-flow (HF/UHF) hotends that need more purging for reliable color changes.

Before (capped at 900) After (uncapped)
Modularize printer agent architecture and add filament sync for third-party AMS-style systems by @SoftFever in #12086
This architectural refactor modularizes the network agent architecture, laying the groundwork for future OrcaSlicer ↔ printer connectivity enhancements. It also introduces experimental filament info sync from printers with material stations or multi-tool systems.
The initial release includes dedicated agents for Moonraker/Klipper, Qidi, and Snapmaker printers, with experimental filament sync from AMS-style material systems including the Qidi filament box, Armored Turtle (AFC) box via Moonraker, and the Snapmaker material station.
Wipe tower interface layer features (ported from Bambu Studio, with improved preheat and cooldown) by @Argolein in #12266
Ports the wipe tower interface stability features from Bambu Studio 2.5.0 and adapts them for non-BBL printers. When mixing materials like PLA and PETG (commonly used as support interface for each other), the prime tower can become unstable due to poor inter-layer adhesion. These features improve tower reliability and layer consistency across multi-material prints.
- Interface-layer boost temperature (set a fixed value, or -1 for filament max)
- Interface-layer pre-extrusion distance to build pressure before tower printing
- Interface-layer purge length and notch at the start point for better stability
- Skip ironing on interface layers; configurable ironing area for other layers
- Slower infill on the layer after the interface layer to improve adhesion
OrcaSlicer-specific improvements:
- Smarter preheat injection — boost preheat G-code is now injected even when the remaining time before a toolchange is shorter than the configured preheat window. Previously, the preheat would be skipped entirely in this case. The preheat command is placed as early as possible after the last tool switch, outside toolchange blocks, without introducing waits or delaying motion.
- Optional cooldown during prime tower — the nozzle can begin cooling back down to print temperature while printing the wipe tower, avoiding color shifts or surface artifacts (especially with PLA) caused by resuming the print at an elevated temperature.
All features are gated behind "Enable tower interface features" in Advanced/Expert settings. When disabled, behavior is unchanged.

Filaments

Organize filament presets by vendor or type by @yw4z in #11681
Four grouping modes for your custom filament presets in the dropdown: All (flat list), None (ungrouped), By Vendor, and By Type. Configurable in Preferences.

By Vendor By Type
Standardized filament types with technical material support by @ianalexis in #10553
Filament type definitions are now standardized, and technical/engineering materials (like nylon composites, polycarbonate blends, etc.) have been added with their associated properties — temperature ranges, bed adhesion requirements, and compatibility info — for better filament management.

G-code Improvements

Show print time and filament usage on your printer's screen by @davydmaker in #12186
A new "File header G-code" option in Printer Settings writes metadata at the top of the G-code file, along with two new placeholders: {print_time_sec} and {filament_length_m}. This lets printers like the Creality Ender-3 V3 SE display estimated print time, filament usage, and layer height directly on the printer's screen.

Instances

Add instances — a faster way to duplicate objects by @vovodroid in #6237
Instead of creating full copies, you can now add lightweight "instances" of an object and use "Fill Bed With Instances" to quickly fill your build plate. Instances share the same model data, so they slice significantly faster than individual copies.
Collision detection now checks duplicated instances by @vovodroid in #11866
When printing objects one at a time ("Print by Object" mode), collision detection now properly checks instances, preventing missed collisions that could cause print failures.

Before (missed collision) After (detected)
Fix fill bed and auto-arrange for instances by @yw4z in #11619
Fixed "Fill Bed" not arranging items after cloning, and disabled auto-arranging after creating instances to preserve manual placement.

Model Quality & Processing

Change part type for multiple selections at once by @xyluphobia in #11544
You can now change the type (Normal, Modifier, Support Enforcer, etc.) of multiple selected parts at once, instead of one at a time.
Mesh Subdivision Ported from BambuStudio by @ianalexis in #12150
You can now right-click a part and choose Subdivide Part to apply Loop subdivision with multiple iterations. This is useful for models with low original mesh resolution.

Original Mesh Divided
Replace with 3D file — now supports STEP and batch replacement by @nilshasler, @ianalexis in #11145, #11637
The "Replace with STL" command has been expanded to support STEP files, and a new "Replace All" option lets you batch-replace multiple parts at once from a folder of matching filenames. Especially useful for production workflows where you repeatedly print the same set of parts with updated revisions.

Support for Draco (.drc) compressed 3D files

Support for Draco (.drc) compressed 3D files by @Maeyanie in #10681
You can now open and save Draco compressed mesh files. Draco files are extremely compact — often under 10% of an equivalent STL file size — with no visible quality loss.
Reduce Orca weight: Resources to Draco by @ianalexis in #12194

New Handy Model

Cali Cat built-in test model by @ianalexis in #11663
The popular Cali Cat calibration model is now available directly from the built-in test models menu (with permission from the model's creator @davidzhen).

Performance & Optimizations

Reduced memory usage for infill generation by @RF47 in #12063
Infill path processing now uses less memory by avoiding unnecessary data copying.
Faster multiline infill processing by @ianalexis in #11415
Re-introduces an optimized geometry library for multiline infill, providing significant speed improvements over the previous version.
~3× faster slicing for resin (SLA) models by @dbaarda in #10747
Major speed improvement to the polygon extraction used in SLA slicing — approximately 3× faster with lower memory usage and better output quality.
Faster equation-based infill patterns by @dbaarda in #10876
The TPMS-FK infill pattern now uses the same optimized algorithm as above, making it significantly faster and easier to maintain.
AutoSlice only triggers on Preview tab by @ianalexis in #12153
AutoSlice recalculation now only runs when the user is in the Preview tab, improving performance when moving objects in other tabs.
Remove unnecessary range checks for bed exclude area by @SoftFever in #11877

Connection & Sync

IPv6 support for printer connections by @andir in #11639
OrcaSlicer can now connect to printers using IPv6 addresses, for users whose networks use IPv6.

Bambulab

H2D/H2S support by @Noisyfox in #10780
Full support for Bambu Lab's H2D and H2S printers, cherry-picked from BambuStudio. Both LAN mode and dev mode must be enabled on the printer, and "Use legacy network plugin" must be turned off in Orca preferences.
Part skip from Orca for Bambu printers by @Noisyfox in #10875
Ported from BambuStudio, this feature allows you to skip printing specific parts in multi-object prints directly from OrcaSlicer. If a part fails or is no longer needed, you can skip it and the printer will continue with the remaining objects.

Note

Firmware requirements: X1C v01.09.02.12+, H2D v01.02.00.00+. Other models will be supported in future firmware updates.

Disable Power Loss Recovery on Bambu Lab printers by @michaelr0, @ianalexis in #11582, #11616
A new toggle in Machine Settings (developer mode) to turn off Power Loss Recovery. This can speed up prints by skipping the recovery checkpoints, and is useful if the feature causes issues on certain firmware versions.
Choose which network plugin version to install by @mLupine in #11645
You can now pick a specific network plugin version instead of always getting the latest. Includes a version selector, instant reload without restarting OrcaSlicer, and support for custom plugin variants. Handy for rolling back if a newer plugin causes problems.
More control over AMS filament sync by @Argolein in #12169
When syncing filament info from your Bambu Lab AMS, you can now choose to sync only the color, or sync all filament properties (type, temperature, etc.). This gives you finer control over how AMS-loaded filaments interact with your configured presets.
Upload to SD cards flagged as "abnormal" by @Seref in #10981
A new option to allow uploads to SD cards that the printer has flagged as "abnormal," with clearer error messages explaining why uploads may get stuck at 10%. Some printers incorrectly flag working SD cards after a power loss or cancelled network print — this setting lets you bypass that warning.
Sort AMS Material Selection by vendor and type by @ansonl in #11261
Fixed AMS Material Selection dialog to sort by both filament vendor and type instead of type only.

📐 Calibration Improvements

Input Shaping calibration: multi-firmware support and improvements by @ianalexis in #10913
The Input Shaping calibration dialog now detects your printer's firmware and shows the correct shaper type options for Klipper, RepRap, Marlin 2, and Marlin Legacy. Acceleration limits and jerk values are set automatically based on what your firmware supports.
New Cornering/Jerk calibration test by @ianalexis in #10962
A new calibration test to find the best cornering/jerk speed for your printer, supporting Marlin (Junction Deviation and Classic Jerk), Klipper (square_corner_velocity), and RepRap firmware. Also adds Marlin 2 Junction Deviation to Machine Settings.
Pressure Advance preserved during calibrations by @ianalexis in #11178
If you have Pressure Advance configured, it is now kept active during Input Shaping and Cornering calibrations instead of being reset to 0.
Pressure Advance calibration now validates your inputs by @ianalexis in #11493
Adds a check to ensure acceleration values are higher than speed values in Pressure Advance calibration, preventing invalid configurations that would produce bad results.
Calibrations now use your configured layer height by @ianalexis in #11835
Calibration prints now use the layer height from your active process profile instead of always using a hardcoded 0.2mm.
More consistent calibration results by @ianalexis in #11988
The "reverse on even" setting is now automatically disabled for most calibration prints, preventing it from interfering with calibration accuracy.
Retraction calibration seam placement fixed by @Andor in #11346
Retraction calibration now forces seams to align to the correct position on the test model, preventing misleading results from seams ending up in the wrong spot.

Wrong seam placement Correct placement
Better retraction calibration with Inner→Outer wall sequence by @ianalexis in #11372
Retraction calibration now uses Inner→Outer wall printing order, making retraction artifacts more visible and easier to evaluate.
Temperature tower for high-temp materials (up to 500°C) by @RF47 in #12103
A new temperature tower spanning 155–500°C for high-temperature materials like PEEK, PEKK, and ULTEM. The test model has been redesigned for better consistency and compressed to a much smaller file size.
Calibrations listed in recommended order by @ianalexis in #11389
"Max volumetric speed" is now listed second in the calibration menu, guiding you to calibrate speed limits first — which prevents underextrusion issues in later Pressure Advance and flow rate tests.
Fixed geometry errors in built-in calibration models by @RF47 in #11861
Fixed geometry errors in the temperature tower, bridge test, and max flow calibration models that could cause slicing warnings or print issues.

Profile Processing Improvements

Smarter default filament selection by @SoftFever in #12124
When OrcaSlicer needs to pick a fallback filament, it now selects the "Generic" profile instead of picking the first vendor alphabetically (which previously defaulted to names like "Aliz").
Save a profile without inheriting from system defaults by @Azio-Pantheon in #7071
You can now create fully independent ("detached") profiles that won't be affected when system profiles are updated. This prevents your custom settings from being unexpectedly changed by future OrcaSlicer updates. Available under developer mode for printer, filament, and process profiles.
