Compare Chitubox vs. Lychee Slicer, two popular resin slicer programs in 2026. Highlights, differences, and how to choose the right one for miniatures, prototypes, or functional parts.

For those who print with resin 3D printers, whether LCD, SLA, or DLP systems, the slicing software is as crucial as the printer itself. It determines how models are oriented, supports are added, and exposure settings are configured before being converted into a machine-readable file. Currently, there are several resin slicing programs available, but the two dominating the market share are Chitubox and Lychee Slicer, both with distinct strengths. This article will explore which program is suitable for which type of work and which one you should choose based on your printing style.

Chitubox: Detailed Control, Ideal for Fine-Tuning

Chitubox is a long-standing resin slicing software that supports almost all printer brands, including Anycubic, Elegoo, Creality, and Phrozen. Chitubox's main strength lies in allowing users to control almost every variable in detail, from the Exposure Time of each layer and Anti-aliasing settings to reduce stair-stepping on model surfaces, to adjusting Layer Transition between bottom layers and normal layers.

For those who enjoy experimenting with exposure settings for different resin brands or performing detailed exposure tests to find the most accurate values, Chitubox Basic (the free version) is a great fit. It supports a wide range of files and printers without cost, making it suitable for tasks requiring high precision, such as functional parts or small molds needing accurate dimensions.

Lychee Slicer: Strong in Support and Miniatures

Lychee Slicer (especially the Lychee Plus version) is renowned for its smarter automatic support management, particularly for complex models like miniatures, figures, or organic shapes. Lychee's Auto-support system accurately analyzes angles and fragile points, reducing the time spent manually adjusting supports.

Another area where Lychee excels is hollowing models with automatic resin drain holes, which saves resin and reduces peel forces during printing. Additionally, it offers an Auto-orientation feature that automatically positions models at the most optimal angle, which is highly beneficial when arranging numerous models on a single build plate for large-batch production.

Real User Tip: Use Both Programs Together

Many experienced users choose to use both programs in conjunction. They start by orienting models, creating supports, and hollowing with Lychee, as its Auto-support system is fast and accurate for miniatures. Then, they take the file to Chitubox for fine-tuning exposure and detailed layer preview inspection before actual printing. This method leverages the strengths of both programs fully, without being confined to just one.

Regardless of which program you use, a crucial step not to skip is checking the Layer Preview by scrolling through each layer before printing. Pay attention to layers with unusually small contact areas with the previous layer, ensure that all "islands" flagged by the system are adequately supported, and verify that the first 10 raft layers are smooth without any holes. Most print failures often hide in these details.

Which one should you choose?

In summary, if your work involves miniatures, figures, or highly detailed models requiring extensive support management, Lychee Slicer will save you more time. If your work prioritizes dimensional accuracy, requires precise exposure control, or involves functional parts needing consistent values, Chitubox offers greater flexibility. For beginners who are unsure, it's recommended to start with the free versions of both. Try them out with models you print frequently, then decide whether to upgrade to a paid version of either, as everyone has different work styles. The "best" program ultimately depends on what you print most often.
