OrcaSlicer v2.3.1 beta Release Pre-release
Pre-release

What's Changed

This is OrcaSlicer V2.3.1 beta release. It fixes some bugs found in 2.3.1-alpha and adds some new features.

  • Add a new feature that allow user to insert extra solid infills by @SoftFever in #10611
    Insert extra solid infills at specific layers to add strength at critical points in your print. This feature allows you to strategically reinforce your part without changing the overall sparse infill density.

    extra-solid-infill

    The pattern supports two formats:

    Interval Pattern

    • Simple interval: N - Insert 1 solid layer every N layers, equal to N#1
    • Multiple layers: N#K - Insert K consecutive solid layers every N layers
    • Optional K: N# - Shorthand for N#1

    Examples:

    5 or 5#1    # Insert 1 solid layer every 5 layers
5#          # Same as 5#1
10#2        # Insert 2 consecutive solid layers every 10 layers

    Explicit Layer List

    Specify exact layer numbers (1-based) using comma-separated values. Each entry may be a single layer N or a range N#K to insert K consecutive solid layers starting at layer N:

    1,7,9       # Insert solid layers at layers 1, 7, and 9
5,15,25     # Insert solid layers at layers 5, 15, and 25
5,9#2,18    # Insert at 5; at 9 and 10 (because #2); and at 18

    [!NOTE]

    • Layer numbers are 1-based (first layer is layer 1)
    • #K is optional in both interval and explicit list entries (N# equals N#1)
    • Solid layers are inserted in addition to the normal sparse infill pattern

    [!TIP]
    Use this feature to:

    • Add strength at stress concentration points
    • Reinforce mounting holes or attachment points
    • Create internal structure for functional parts
    • Add periodic reinforcement for tall prints
    • Insert a single solid layer at a specific height by using an explicit list with a leading 0, which will be ignored because layer indices are 1-based. Example: 0,15 inserts a solid layer only at layer 15.

    [!WARNING]
    Layers that include solid infill can take significantly longer than surrounding layers. This time differential may lead to z-banding-like bulges. Consider adjusting cooling or speeds if you observe artifacts.

  • Refactor infill rotation by @SoftFever in #10587
    This update enhances the user experience and logic of the infill rotation controls by making "Sparse infill direction" and "Sparse infill rotation template" mutually exclusive to avoid conflicts. When the "Sparse infill rotation template" is active (non-empty), both "Sparse infill direction" and the automatic 90-degree rotation logic for certain patterns (e.g., Line pattern) are automatically disabled for clearer behavior.

    Solid infill handling has been improved by removing the solid infill insertion code from the sparse infill rotation template system, as this functionality was misplaced in 2.3.1-alpha. A dedicated option has been added for this feature (see change note above). The previous implementation caused issues where solid infill was incorrectly inserted directly above sparse infill.

    The overall infill rotation logic has been refactored for better maintainability and clarity, also resolving a critical regression where auto internal bridge infill direction was not functioning correctly in 2.3.1-alpha (#10469).

  • Fix a regression bug in 2.3.1-alpha where Rectilinear infill generates unoptimized toolpaths. by @SoftFever in #10649

  • Fix a bug where Orca didn't allow exporting the "Printer Config Bundle" in certain cases. by @Azio-Pantheon in #10380

  • Improve Fisher koch Infill Precision by @RF47 in #10428
    Improved curved infill pattern quality by replacing lookup tables with direct trigonometric functions, eliminating grid artifacts and delivering naturally smooth curves with full floating-point precision. This enhancement produces more accurate, visually appealing infill patterns while improving performance.
    image

  • Optimize 3DHoneycomb infill: avoid using bridge flow by @gringer in #10453

  • Ignore the precise outer wall option when the wall sequence is not set to InnerOuter. by @SoftFever in #10687

UI & UX

  • GCodeViewer will now always show the estimations by @niklasb22 in #10333
  • Fixed a bug that legend window increases endlessly on some Linux distros by @yw4z in #10501
  • Fix: Reset object settings not working for plate's Skirt Start Angle and Other Layers Sequence by @yw4z in #10482
  • Fix crash when opening AMS humidity popup by @Noisyfox in #10472
  • Fix scaling on bed and extruder icons in BBL > Device tab by @yw4z in #10416
  • Add stl, step, etc. to recent list by @vovodroid in #9481
  • Fixed many profile issues and cleaned up some messes. by @SoftFever in #10686
    In the filament selection dialog, some incompatible filaments from some vendors are shown, this is fixed now.

OrcaSlicer V2.3.1-alpha Release Notes

OrcaSlicer V2.3.1-alpha is a comprehensive update focused on infill, surface control, motion tuning, and workflow polish. In this release we’re introducing a template-based sparse infill rotation system; two new fuzzy skin features—fuzzy skin (extrusion mode) and fuzzy skin painting; improved flow rate calibration; and built-in Input Shaping and Junction Deviation calibration. Multi-material printing gains color remapping and a sturdier RIB wipe tower. You’ll also see UI refinements, performance improvements, and broader printer support, including the latest BambuLab firmware and AMS 2/HT.

Below is the full changelog—thanks to everyone who tested builds and contributed PRs.

🎯 New Features and Enhancements

  • New sparse infill rotation system by @SoftFever and @pi-squared-studio in #9924 and #9996

    OrcaSlicer now allows you to specify Sparse Infill's rotation pattern in any possible way by using the newly introduced template meta-language(kudos to @pi-squared-studio)

    infill_rotate.mp4

    If you want to learn more about the new rotation system, please visit our WIKI: infill_rotation_template for detailed documentation.

  • Infill Line Multiplier by @RF47 and @profOnno in #9432
    We're introducing the new Infill Line Multiplier feature, giving you greater control over your print's internal structure.
    This option lets you multiply the number of infill lines while preserving your chosen infill density, providing more flexibility
    to balance strength and material distribution.

    By increasing rigidity and fine-tuning material usage, you can create complex, customized internal structures
    tailored to your printing needs—while maintaining consistent cross-sectional weight.

    442467934-a0b404a4-ac3d-471c-ad50-1fc5052052ec

  • Improve flow rate calibration: use ipArchimedeanChords pattern for flow rate calibration by @SoftFever and @Noisyfox in #8993

    The surface pattern and printing sequence in OrcaSlicer’s flow rate calibration test have been redesigned for improved accuracy. You can now identify the correct block not only by visual inspection but also by feeling for the smoothest surface at the ring, making it easier to determine the most accurate flow rate.

    This method is inspired by jimcorner

  • New calibration- Input Shaping & Junction Deviation by @ianalexis and @RF47 in #9160

    OrcaSlicer now introduces comprehensive input shaping and junction deviation calibration tools to optimize motion control on Marlin 2 and Klipper-based printers. Through a two-step calibration process—first identifying the optimal input shaping frequency, then fine-tuning damping ratios—users can significantly reduce ghosting and vibration artifacts. With support for Marlin’s M593 G-code and initial Klipper compatibility, the feature provides granular control, a dedicated calibration UI, and has been validated across a wide range of machines from Ender-3 class printers to high-performance models like the Voron 2.4 and FLSun T1 Pro. By building on proven resonance compensation techniques from Klipper, OrcaSlicer makes advanced motion tuning accessible to more printers, enabling cleaner, higher-quality prints.

  • Feature: Fuzzy Skin Extrusion Mode by @pi-squared-studio in #9878

    Now OrcaSlicer implement a novel way fuzzy skin! Instead of creating jagged tool path to create fuzzy skin effect. This new approach create fuzzy skin effect by simply alter extrusion(flow).
    fuzzy

  • Add fuzzy skin painting by @Noisyfox in #9979

    Ported from PrusaSlicer by @Noisyfox, we can now paint the areas we want to apply the fuzzy skin.
    This new paint-on fuzzy skin feature lets you brush texture directly onto chosen surfaces, giving precise control over where the rough, randomized finish appears. It’s ideal for adding grip, decoration, or selective surface detail without affecting the entire print.

    fuzzy_paint.mp4

  • Introduce a new seam alignment option: Aligned back by @SoftFever in #10255

    We’ve added a new option for seam placement to improve print aesthetics on front-facing models, such as sculptures or designs with a clear viewing direction.

    Previously, using the Aligned seam option could result in seams being placed at the front, which is often undesirable. The new option prioritizes placing seams away from the front while still searching for optimal hidden positions on other sides.

    image image image Unlike the Back option, which always forces seams to the backmost position, this approach provides a more balanced and visually pleasing result. You can see the difference in below video:

  • Remap filament for pre-colored models by @SoftFever in #10303

    This release introduces an intuitive color remapping feature that addresses a common workflow challenge when printing pre-colored models. Users can now easily adjust filament assignments when a model's built-in color sequence doesn't match their printer's loaded filament order, eliminating the need to physically rearrange filaments or modify the original model files.
    This is particularly useful when working with pre-painted models where the artist's intended color order differs from your current extruder setup. For example, if a model expects red, blue, green, yellow but your printer has blue, red, yellow, green loaded, you can now simply remap the assignments through the interface.

    This enhancement streamlines the multi-material printing workflow, making it significantly more convenient to print pre-colored models regardless of their original color assignments.

    remap.mov

  • Adds resonance avoidance ported from qidi slicer by @EpiphanyPrinting in #9403

    You can now set a resonance avoidance range in OrcaSlicer. When enabled, the slicer will skip over such a zone of speeds automatically and choose a nearest safe value, minimizing the occurrence of the vibration-induced ripples and VFA artefacts all too commonly witnessed within such zones. This option is particularly beneficial on those printers which are prone to mechanical resonance, where you can entirely skip those offending speeds. You can obtain the correct range on your machine by running the integrated VFA calibration test available within OrcaSlicer.
    image

  • Junction Deviation Machine Limit by @RF47 in #9234
    This update introduces new Junction Deviation (JD) option, allowing users to configure the maximum JD value on printers running Marlin firmware. As JD has replaced the older jerk parameter in recent Marlin versions, it is now the preferred motion control setting. A corresponding menu is also added in the print settings panel.

    The JD value is applied only when the firmware is Marlin, and the “Emit Limits to G-code” option must be enabled for the setting to be included in the generated G-code.

OrcaSlicer V2.3.0 Official Release

This is the official release of Orca Slicer v2.3.0, a stable version that we highly recommend for all users.

Note: If you upgrade from OrcaSlicer 2.2 or an older version, there’s a chance that some of your previously custom filaments are now available to all your printers. However, if this isn’t what you want, you can set the filament’s dependency to restrict it to a specific printer. For custom filament settings created with 2.3, it will automatically set to be compatible with the current printer model only. In the following video, I demonstrate how to change my “Aliz PETG @voron” filament, which is optimized for my Voron machine and won’t work with my other printers. I set its dependency to make it visible only to my Voron machine.

OrcaSlicer V2.3.0 Release Candidate Pre-release
Pre-release

This is OrcaSlicer V2.3.0 Release Candidate release.

This release introduces new features and fixes bugs identified in the two previous beta versions.

What's Changed

  • Limit visibility of custom filament profiles based on OrcaFilamentLibrary to currently selected printer only by @SoftFever in #8779
    With the newly introduced Global Filament Library in 2.3.0, when users save custom filament profiles, if the base profile is from the Orca Filament Library, these user profiles will automatically become visible to all printers, which can be annoying.
    To address this, we now ensure that new user profiles derived from system profiles (from the Orca Filament Library) are automatically set to be visible only to the selected printer model.
    Users can also manually adjust the compatibility of filament profiles in the filament settings if they want.

  • QoL: Add auto perspective by @Noisyfox in #8312
    This new QoL feature introduces auto perspective that works similar to Blender:

    • When click the top/bottom/left/right/front/back on the 3D navigator, or switch to those view from the menu, or by shortcuts (Ctrl+1-6), the camera automatically switch to orthogonal view
    • When switch to any other angles, either by dragging with mouse/track pad, or by clicking other non-perpendicular faces on 3D navigator, or select default view from menu/short cut (Ctrl+0), the camera automatically switch to perspective view
    • Panning and scalling won't trigger the view change
    • This is optional and disabled by default, you can enable this from the view menu
      image

    This new feature also fixes a few issues with 3D navigator:

    • When click top/bottom view, sometimes the orientation is wrong. Now the orientation is always the same as if you select the top/bottom view from the view menu or by the shortcut.
    • When dragging the 3d navigator vertically, once the vertical limit is reached and you keep dragging it, the view will keep fliping diagonally (gimbal lock, techenically). This issue is illustrated as below, and has been fixed in this PR and the orientation is stable. flipping

  • pa calib: batch mode for pa pattern by @buzzhuzz in #7199
    A new batch mode for PA pattern calibration: generate a set of tests for a given list of accelerations and printing speeds.
    https://github.com/user-attachments/assets/8797fe34-6836-4918-81e3-5e333b48c53f

Pre-release

This is OrcaSlicer V2.3.0 beta release.

We have introduced many new features and improvements in this version.

Before we dive into the details, I would like to share 3 great news.

  1. Orca Slicer has been honored with the Software of the Year award from 2024 3D Printing Industry . A huge thank you to all the contributors and supporters—this project wouldn't be what it is today without you! I'd like to especially thank @Noisyfox and @igiannakas for their exceptional contributions and dedication to the project.
  2. Printables.com now support "Open in OrcaSlicer" feature, you can now open models in OrcaSlicer directly from Printables.com. Kudos to Josef Průša and his team for making this happen!

  3. Orca Slicer has it's own official website now! https://www.OrcaSlicer.com

What's Changed

  • Orca filament profile system rework and global library by @SoftFever in #8287, #8057

    This update introduces infrastrature changes of OrcaSlicer's profile management system as well as a global filament library in OrcaSlicer, addressing one of the most significant challenges users face: organizing filament profiles, especially when managing multiple printers. Previously, filament profiles could not be reused across different printer brands (e.g., Voron profiles did not work on Vzbot and vice versa). The lack of a shared filament library made it particularly difficult to add filament vendor profiles for all printers in Orca, as users had to perform this task individually for each printer model.

    With this new update:

    • A global filament library has been added to Orca, allowing filament presets to be used across all printer models if desired.
    • Filament profiles in Global library can be specialized for specific printer models. E.g. a specially tuned filament profile for certain printer model. When both generic and specialized versions of a filament profile are available, Orca will automatically select the appropriate one based on the printer model.
    • The process of creating filament profiles has been simplified, encouraging manufacturers to submit their profiles directly to Orca. Which again will make life easier for all users.

    Some sample filaments have been added to the global library with this update too, enabling all machines to use them. This feature represents a significant step forward in streamlining filament management within OrcaSlicer.
    image

  • enabled dependency setting for filament and process by @Azio-Pantheon in #6235
    This update re-enables the dependency setting UI for filament. Along with the Orca filament profiles syterm rework, users now can set dependencies for filament so that the custom filament can be used in by other printer.

    Screen.Recording.2025-01-15.at.11.24.14.PM.mov

  • Introduce more fuzzy skin styles(structured noise/perlin) by @Arachnid in #7678
    The existing fuzzy skin support does a good job of hiding printing artefacts, but uses a very naive algorithm based on randomly displacing points on the outside wall of an object. This means that there's no correlation between the displacements of vertically adjacent points, and this in turn gives the fuzzy skin a characteristic horizontal pattern that can accentuate rather than hide layer lines.
    This new enhancement adds support of creating structured noise, and uses it to enhance the fuzzy skin functionality with new options that have better aesthetics compared to the existing uniform random noise. Several noise algorithms are supported:

    1. Perlin noise: A classic structured noise algorithm that creates spatially coherent noise.
    2. Billow noise: A variation on perlin noise that has a more 'billowly' or cloud-like appearance.
    3. Ridged Multifractal noise: Creates random ridgelike formations, or marble-like textures.
    4. Voronoi: Divides space up into voronoi cells, and displaces each by a random amount. Creates a patchwork effect.

  • Add "2D Lattice" fill pattern for lightweight aircraft structures by @LoftedAero in #8293
    This is a new fill pattern intended for lightweight printed model aircraft structures, primarily wings with single walls and low fill percentages. It creates a 2D lattice structure extruded in a planar direction, typically perpendicular to the wing chord but able to be manipulated by the fill angle setting. The lattice elements are arranged in two alternating groups, each with a user-specified angle relative to the Z direction. These two angles are adjustable by the user via settings that appear when this fill type is selected.

  • Extrusion rate smoothing improvement by @igiannakas in #7398:

    1. Reduce redundant gcode commands from extrusion rate smoothing by @igiannakas
      Extrusion rate smoothing (pressure equaliser) materially increases gcode size due to significant redundancies in the produced gcode.
      This improvement reduce gcode size, making the gcode smaller and hence, more easily printable due to reduced gcode commands / second issued to the printer.
    2. Introduces an option to limit ERS to the areas that are visible to the user, reducing print time impact.
    3. Allow smaller segment length

  • Expose interface_shells option by @SoftFever in #8411
    "interface_shells" option exists in original PrusaSlicer, this PR just expose this option as this is a useful feature for people want to print multi color logo or sign.

  • Enhancement: Additional controls over bridges by @igiannakas in #8263
    The following features have been developed

    1. Internal bridge density: can help improve internal bridge reliability by improving cooling efficacy for the bridge layer as the lines can be spaced a bit further apart. It can also help reduce over extrusion if thick internal bridges are selected as the extra spacing allows for the material to spread down/side more easily.
    2. Second bridge layer over internal bridge: significantly improves robustness of the internal solid infill, especially for high speed high acceleration printers, as it allows for multiple layers of material to be laid down slowly (using the internal bridge settings) before speeding up for internal solid infill. As a bonus it slightly reduces benchy hull line as material contraction is spread over more layers, more gradually.
    3. Second bridge layer over external bridge: significantly improves robustness of the external bridge before transitioning to the solid infill.
