Resin Slicer Comparison: Lychee vs Chitubox vs Photon

Introduction to Resin Slicer for MSLA Printing

If you’ve ever pulled a failed print off your build plate and wondered what went wrong, chances are your resin slicer settings were part of the problem. Choosing the right resin slicer isn’t just a matter of personal preference — it directly shapes your print quality, support reliability, and overall workflow speed. Whether you’re printing miniatures, dental models, or engineering prototypes, the resin slicing software review you’re reading right now will help you make a confident, informed decision.

A resin slicer is the bridge between your 3D model and your printer. It converts a mesh file (STL, OBJ, or similar) into a series of exposure layers that your MSLA printer reads one by one. Get the settings right, and you’ll see crisp details, clean supports, and smooth surfaces. Get them wrong, and you’re looking at warped layers, support failures, or prints that never stick to the plate.

In this guide, we’re diving deep into the three most widely used resin slicers in 2026: Lychee Slicer, Chitubox, and Anycubic Photon Workshop. We’ll compare their support systems, workflow speed, advanced features, and real-world performance — so you can pick the one that fits your setup and skill level.

What Is MSLA Printing Software?

Before jumping into comparisons, let’s quickly clarify what MSLA slicer software actually does and why it matters.

MSLA stands for Masked Stereolithography Apparatus. Unlike FDM (filament) printers that melt plastic layer by layer, MSLA printers use a UV light source masked by an LCD screen to cure liquid photopolymer resin one layer at a time. The LCD panel acts as a mask, exposing only the cross-section of your model per layer.

This is where MSLA printing software comparison becomes critical. The slicer must:

• Slice your model into thin horizontal layers (typically 0.05mm or less)
• Generate support structures that hold overhangs and prevent sagging
• Calculate exposure settings — how long each layer is exposed to UV light
• Export the file in a printer-compatible format (CTB, PWMO, LYS, etc.)

Each slicer handles these tasks differently, with different levels of automation, customization, and compatibility. The right MSLA slicer software can mean the difference between a 3-hour successful print and a plate full of cured soup.

Lychee Slicer Overview

Lychee Slicer, developed by Mango3D, has rapidly become one of the most talked-about names in the resin printing community — and for good reason. It’s frequently cited as a top contender for best resin slicer 2026, and it earns that reputation through a combination of smart automation, a polished interface, and an active community ecosystem.

Key Strengths of Lychee Slicer

AI-Powered Support Generation Lychee’s standout feature is its AI support system. Rather than placing supports based on simple overhang angle rules, the AI analyzes your model geometry and places supports where they’re actually needed. This dramatically reduces support failures without requiring you to manually inspect every millimeter of your model. For Lychee Slicer supports, the results are consistently impressive, especially on complex organic shapes and miniatures.

Community Resin Profiles Lychee hosts a cloud-based library of community-contributed resin profiles. Instead of manually dialing in your exposure settings for a new resin, you can often find a tested profile uploaded by another user with the same printer and resin combination. This is a massive time-saver for beginners.

Clean, Modern UI The interface is intuitive and visually organized. Navigation between the prepare, support, and slice stages feels logical. The layout works well on both high-resolution monitors and more modest setups.

Freemium Model Lychee offers a free tier with core functionality, plus paid tiers (Pro and Premium) that unlock AI supports, advanced hollowing, and cloud sync. For most hobbyists, the free or Pro tier covers everything they need.

Broad Printer Compatibility Lychee supports printers from Elegoo, Anycubic, Phrozen, Creality, and many others, making it versatile across the MSLA ecosystem.

Chitubox Deep Dive

Chitubox, developed by CBD-Tech, was for a long time the default slicer for many resin printer manufacturers — and it still ships as the recommended software for a wide range of machines. Its reputation is built on raw control and compatibility depth.

Chitubox Slicer Settings: Power and Precision

Chitubox gives users granular control over virtually every parameter of the slicing process. For experienced users, this level of depth is invaluable.

Advanced Exposure Control Chitubox slicer settings allow you to fine-tune normal layer exposure, bottom layer exposure, lift speed, retract speed, and rest time with precision. This matters a great deal when printing highly detailed models where overexposure can blur fine features.

Resin Print Supports Chitubox’s support system is powerful but more manual than Lychee’s. Auto-support works reasonably well for simple models, but for complex geometries, you’ll often need to go in and add or adjust supports by hand. The upside is that you have full control over support density, tip diameter, pillar shape, and connection angle. Users who understand support geometry can achieve very clean results with minimal scarring on the model surface.

Hollow and Drain Holes Chitubox includes reliable hollowing tools with customizable wall thickness and built-in drain hole placement. This is essential for reducing resin consumption and preventing suction cup failures on large flat-bottomed prints.

Compatibility Chitubox supports a vast range of printers and output formats. Its CTB format is one of the most widely supported file types across MSLA printers. Chitubox Basic is free, while Chitubox Pro adds features like anti-aliasing, image blur settings, and multi-platform export.

Learning Curve Chitubox’s UI is functional but can feel cluttered to newcomers. The sheer number of settings panels can be overwhelming at first. However, once you understand the workflow, it becomes a reliable and consistent tool.

Anycubic Photon Workshop Breakdown

Anycubic Photon Workshop is the official slicer developed by Anycubic for their line of Photon resin printers. It takes a different approach from Lychee and Chitubox by prioritizing simplicity and tight brand integration over feature depth.

Designed for the Anycubic Ecosystem

Anycubic Photon Workshop is built primarily for Anycubic printers — the Photon Mono series, the Photon M3, and the Photon Ultra, among others. If you own an Anycubic printer, this slicer is optimized out of the box for your hardware. Firmware updates from Anycubic often come bundled with Photon Workshop profile updates, keeping the two in sync.

Beginner-Friendly 3D Printer Resin Workflow

The 3D printer resin workflow in Photon Workshop is streamlined for simplicity. The interface has fewer panels and options than Chitubox or Lychee, which makes it much less intimidating for first-time resin users. You load a model, orient it, add supports, set layer height, and export. The steps are clear and logically ordered.

Support generation in Photon Workshop is automated and reasonably reliable for standard models. It doesn’t have the AI sophistication of Lychee, but for typical hobby prints, it gets the job done.

Limitations

Where Photon Workshop falls short is in customization depth and cross-brand compatibility. The software works best with Anycubic printers and becomes less useful outside that ecosystem. Advanced users looking to fine-tune anti-aliasing, experiment with non-linear exposure curves, or use community resin profiles will quickly find themselves reaching for Lychee or Chitubox instead.

That said, for Anycubic users who want a stable, no-fuss slicer that just works, Photon Workshop delivers exactly that.

Supports Comparison: Which Handles Them Best?

Support structures are arguably the most critical aspect of resin printing. Unlike FDM, where failed supports might leave a rough surface, failed resin supports often mean the entire print falls off the plate mid-print. Getting resin print supports right is non-negotiable.
