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)

  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.
  
  
  

• 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).
  

• 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.

• 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.

  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.

• 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.
  

• 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.

  

• Introduce RIB wall feature for wipe tower, inspired by BambuStudio by @anjis-elegoo in #9881
  OrcaSlicer now allows the multi‑color wipe tower to include the RIB wall, an enhanced structural option that uses internal ribs to significantly boost tower stability during multi-material prints. This makes wipe towers sturdier—particularly useful for taller or frequent tool‑change jobs—and ensures cleaner filament purges while minimizing wobble and print artifacts.
  

• Top/bottom surface pattern density by @Buildasaurus in #9783

  OrcaSlicer now allows you to set the density of top and bottom surfaces, making it possible to move beyond fully solid layers and create artistic, patterned finishes. This gives prints a new aesthetic dimension while still preserving structural strength where needed.
  

• Enable ironing and shell options for spiral vase mode by @ianalexis in #10115

  

• Ironing support interfaces by @Noisyfox in #9548

  OrcaSlicer now allows ironing on support interface layers, giving you the choice to smooth supported top surfaces for a cleaner, more polished finish, especially in multi-material prints.

• Add ironing fan speed control by @Noisyfox in #9944

  The new option allows users to set the fan speed specifically for ironing, providing finer cooling control to achieve smoother, more polished surfaces. This is particularly useful for support interface layers, where precise airflow helps maintain filament flow while improving surface quality. Check the image below for comparison:

• Port STEP import dialog from BambuStudio by @Noisyfox in #9102

  We have more control over the details when we import a STEP file into OrcaSlicer.
  

• gCode Legend & Viewer Improvements by @yw4z in #8198

  The G-code legend now offers a more compact layout, giving the viewer a cleaner, sleeker appearance while maximizing space for the print preview.
  

• Add Lateral honeycomb infill pattern by @elektrohenk in #9483

  A new lateral honeycomb infill pattern has been introduced, designed primarily for applications such as aircraft wings. Similar to ribs and stringers in traditional wing structures, this infill supports thin skins under aerodynamic loads and prevents oil-canning during printing.

  Compared to lateral lattice, honeycomb provides the same torsional stiffness with up to 33% lower weight. To address the inherent 60° overhang of honeycomb, we’ve added a new infill overhang angle parameter, which vertically stretches the pattern. This adjustment maintains the weight advantage at lower overhang angles. However, note that lateral honeycomb has limitations: vertical density distribution is uneven, and the pattern cannot self-subdivide. As a result, local density increases with modifiers may cause line disconnects.
