Slicers

Overview

Slicers are the software bridge between a 3D model and your printer — they translate geometry into toolpath instructions (G-code or proprietary variants). The consumer FDM slicer landscape has consolidated significantly since 2022, with OrcaSlicer emerging as the community-dominant open-source option as of 2025. Resin printing uses a separate class of slicers — most notably Chitubox and Lychee Slicer — that generate layer images rather than toolpaths.

OrcaSlicer

Status: Actively developed — current community favorite

OrcaSlicer is an open-source slicer developed by SoftFever, first released in 2023. It is forked from Bambu Studio (which is itself forked from PrusaSlicer), and supports a wide range of FDM printers including Prusa, Bambu Lab, Voron, Creality, and many others.

Why it has become dominant

By 2025, OrcaSlicer displaced SuperSlicer as the go-to advanced open-source slicer for the broader community. It absorbed and extended much of SuperSlicer's feature set while maintaining active development and broad printer support. Users of non-Bambu printers who want Bambu Studio-level polish with full control gravitate here.

Key features

  • Arachne perimeter generator
  • Built-in calibration workflows (Pressure Advance, flow rate, temperature towers, retraction)
  • Multi-material / MMU support
  • Variable layer height
  • Advanced support interface options
  • Frequent release cadence with active community contributions

Bambu Studio

Status: Actively developed — required for full Bambu Lab feature access

Bambu Studio is the official slicer from Bambu Lab, forked from PrusaSlicer and serving as the upstream base for OrcaSlicer. It is the primary slicer for Bambu Lab printer owners, offering tight hardware integration including cloud printing, AMS multi-color workflows, and device management.

Key features

  • First-class support for Bambu Lab printers (X1C, P1S, A1, etc.)
  • AMS (Automatic Material System) multi-color/multi-material workflow
  • One-click print profiles tuned for Bambu hardware
  • Cloud and LAN print modes
  • Regularly updated in step with Bambu Lab firmware releases

Note: Bambu Studio's Bambu-specific features (AMS management, cloud sync) are not available in OrcaSlicer. Users with Bambu printers who want those integrations should use Bambu Studio; users who want more calibration control can use OrcaSlicer for the same hardware.

PrusaSlicer

Status: Actively developed

PrusaSlicer is an open-source slicer developed by Prusa Research, originally forked from Slic3r. It is the upstream ancestor of both Bambu Studio and OrcaSlicer, and remains the reference slicer for the Prusa ecosystem.

Key features

  • Optimized profiles for all Prusa printers (MK4, XL, MINI+, etc.)
  • Paint-on supports and seam placement
  • Variable layer height editor
  • Multi-material / MMU3 support
  • Broad third-party printer profile library
  • Modern UI with beginner and advanced modes

Cura

Status: Actively developed under UltiMaker (formerly Ultimaker)

Cura is one of the longest-running and most widely used open-source slicers. Originally developed by David Braam and adopted by Ultimaker, the software continued development after Ultimaker's 2022 merger with MakerBot (under Stratasys) to form the combined UltiMaker brand. The slicer is now maintained under the UltiMaker name but remains free and open-source.

Key features

  • Extremely broad printer compatibility with a large community profile library
  • Plugin marketplace extending core functionality
  • Beginner-friendly interface with optional expert mode
  • Direct CAD integration (Fusion 360, SolidWorks, etc.)
  • Large user base with extensive community documentation

SuperSlicer

Status: Development largely stalled — superseded by OrcaSlicer

SuperSlicer is a community fork of PrusaSlicer that added advanced features — ironing, dynamic speed control, granular extrusion width control — ahead of the main PrusaSlicer branch. It was popular with power users from roughly 2020–2023.

As of 2024–2025, SuperSlicer development has effectively stalled. Most of its defining features have been absorbed into OrcaSlicer and PrusaSlicer. New users seeking SuperSlicer's advanced control are generally directed to OrcaSlicer instead.

Note: SuperSlicer is still functional and usable, but it no longer receives meaningful updates. Existing profiles can often be imported into OrcaSlicer.

Resin Slicers

Chitubox

Status: Actively developed — de facto standard for MSLA/DLP resin printing

Chitubox is a resin slicer developed by CBD-Tech, first released in 2019 and now the most widely used slicer in the MSLA and DLP resin printing ecosystem. It supports an exceptionally broad range of printers from Elegoo, Anycubic, Phrozen, Creality Halot, Peopoly, and dozens of other manufacturers, outputting printer-native formats including the ubiquitous .ctb format used across Chitu Systems-based printers.

Chitubox ships in two tiers: a free version covering core slicing, manual and auto-support generation, and basic hollowing; and Chitubox Pro, a paid perpetual-license or subscription option that adds more advanced support editing, multi-island detection, a parametric support tree system, and batch processing. As of 2024–2025, the free tier remains capable enough for most users, while Pro targets professionals and studios with high print volumes.

Key features

  • Broad MSLA/DLP printer compatibility across most major consumer brands
  • Outputs .ctb and other Chitu Systems-native formats as well as open .photon, .pwmx, and similar formats
  • Built-in hollow tool with configurable wall thickness and infill
  • Drain hole placement tool (manual and auto)
  • Auto-support generation with manual editing; Pro tier adds parametric tree supports and per-island control
  • Island detection (Pro tier; basic detection available in free)
  • Print time and resin volume estimates
  • Active development with regular releases; version 2.x branch introduced a modernized UI

Lychee Slicer

Status: Actively developed — leading alternative to Chitubox with stronger auto-support tooling

Lychee Slicer is a cross-platform resin slicer developed by Mango3D, available on Windows, macOS, and Linux. It operates on a freemium model: a capable free tier handles basic slicing and manual supports, while a paid Pro subscription (monthly or annual) unlocks AI-assisted auto-supports, island detection and repair, advanced support customization, and priority export speeds. Lychee has steadily grown its user base since 2021 and is widely considered the strongest direct alternative to Chitubox.

Lychee's primary differentiator is the quality of its AI auto-support generation, which tends to produce more structurally efficient and easier-to-remove supports than Chitubox's equivalent tooling. Its island detection and one-click repair workflow are particularly valued for complex miniature and jewelry prints where unsupported islands cause costly failures.

Key features

  • Cross-platform: Windows, macOS, and Linux
  • Free tier covers slicing, basic support placement, and export for a wide range of supported printers
  • AI auto-support generation (Pro) with tunable density, tip size, and contact point profiles
  • Island detection and guided repair workflow (Pro)
  • Advanced hollowing with variable wall thickness and drain hole placement
  • Print statistics, resin cost estimation, and plate management
  • Regular updates with active community engagement; supports most major MSLA/DLP consumer printers
  • Scene-based plating workflow supports multiple models with independent settings per model

Choosing a Slicer

Slicer Best for Status
OrcaSlicer Most FDM printers, power users, community-standard advanced features Active
Bambu Studio Bambu Lab printer owners needing AMS / cloud features Active
PrusaSlicer Prusa printer owners; solid general-purpose option Active
Cura Broad compatibility, large community, beginner-friendly Active
SuperSlicer Legacy users with existing profiles Stalled
Chitubox MSLA/DLP resin printing; broad printer support; industry-standard .ctb format Active
Lychee Slicer Resin printing with strong AI auto-supports; multi-platform users Active

For most new users on non-Bambu hardware, OrcaSlicer is the recommended starting point. Bambu Lab printer owners should start with Bambu Studio and evaluate OrcaSlicer if they want additional calibration tools. For resin printing, Chitubox is the most widely used starting point and supports the broadest range of MSLA and DLP printers out of the box; Lychee Slicer is a strong alternative worth evaluating if AI-assisted auto-support generation and island detection are priorities.
