CHITUBOX Review

CHITUBOX is a resin slicer: it turns a 3D model into layers and settings your printer can use. It’s worth trying if you want one program to arrange models, add supports to hold them during printing, and export the finished file. Start free. Pay when a particular tool helps with work you do often. You still need to check supports and choose settings that suit your resin and printer.

This review covers CHITUBOX 1.3.0, the app that brings the older Basic and Pro lineup together. It offers free access and paid Advanced or Pro subscriptions. Choosing a plan can be confusing: an older Basic tutorial may show a useful feature without telling you which subscription includes its controls today.

Will CHITUBOX work with your setup?

Check your exact printer model first. CHITUBOX lists many Elegoo, Anycubic, Phrozen, and other resin printers, but support for a brand doesn’t cover every machine. The Mars 3 uses .ctb, for example, while the Mars 5 uses .goo. A model opening successfully on your computer doesn’t prove that your printer can read the exported file.

Match the printer profile, output format, and printer firmware—the software running inside the printer. Follow the printer maker’s compatibility instructions before changing firmware. Don’t alter a preset’s screen resolution or build dimensions to force a file to fit another printer.

Keep these file types separate:

For Windows, the current installation guide specifies Windows 10 version 1607 or later, 16GB RAM, 20GB storage, and graphics memory of at least 1GB. Its minimum processors are an Intel Core i5-6600K or AMD Ryzen 5 1600; 32GB RAM is recommended. Mac and Linux users should confirm an installer and requirements for the exact release before committing. Older Basic downloads and instructions aren’t proof of current platform support.

Paid features require signing into the account holding your subscription. ChituManager is a separate companion for network transfer and printer monitoring, not a requirement for ordinary USB-file preparation. Network sending needs a supported printer on the same local network as your computer. Manager can retain printers locally without login; signing in adds cloud synchronization.

What happened to CHITUBOX Basic and Pro?

CHITUBOX still has free access. The separate Pro application has been replaced in the current lineup, so you don’t need to start by choosing between two installers. “Pro” doesn’t always mean the same thing in an older review and today’s subscription menu. References to “CHITUBOX 3” can also concern the earlier transition to the redesigned app; a bigger version number doesn’t necessarily mean a newer download.

Older Basic included automatic and manual supports, hollowing, drain holes, and model repair. Hollowing wasn’t exclusively a Pro feature. Don’t assume that every hollowing option or support-editing control remains free in the unified app, though.

The current manual describes tools across the app without consistently identifying their subscription limits. Before paying, check the exact action you need in your account’s plan: changing support contacts, adjusting drain holes, or applying supports to a selected area. A visible button alone doesn’t establish free access to all its settings.

The most useful tools to investigate are those that replace repeated clicks. Batch Support applies supports to selected areas. Magic Support runs successive support steps with different settings. Model cutting and text labels can help if you regularly prepare files supplied by someone else. Older Pro offered these kinds of additional controls; their value comes from the work they help you finish, rather than the edition name.

Paid access means adding a subscription to your printing costs. Current license management lists personal licenses for up to two computers and team licenses for up to five, with automatic-renewal controls. Don’t treat a two-computer allowance as a license for two people.

CHITUBOX Dental is a separate specialist product with dental application presets, including orientation for orthodontic models. It has its own license and online verification. It isn’t the natural upgrade for someone printing miniatures; a dental lab needs to assess its specific printer and dental workflow separately.

How much work goes into preparing a CHITUBOX print?

The basic sequence is understandable: choose the printer, import your model, arrange it, add supports, and slice it. Learning where to click is only part of the job, though. The harder part is deciding how the model should be held while it prints.

Start by choosing the model’s angle. Supports are temporary structures connecting parts of the model to the build plate—the printer’s flat mounting surface—or another supported area. Rotating the model changes where they’re needed and where their contact marks may appear. For a figure, think about the face and other details you want to keep clean. There isn’t one angle that suits every shape.

Automatic supports give you a starting arrangement. Inspect the underside afterward, especially small features that begin separately from the main body. CHITUBOX’s manual controls let you add supports and change existing structures. After changing some support settings, you’ll need to generate the supports again. Check that their shape actually changed before moving on.

Support size involves a compromise. Larger contact points generally hold more firmly but can leave more noticeable marks when removed. Smaller contacts protect fine detail only if they’re strong enough to keep the part attached. Adding supports everywhere can leave you with more cleanup without solving the original weak point. Adjust the area that needs help, then inspect it again.

Hollowing removes the solid interior to reduce resin use. It also creates extra preparation work: the cavity needs suitable openings, and its inside surfaces may need support. CHITUBOX provides hollowing and drilling tools, but don’t treat a hollowed model as finished simply because its outside looks unchanged. For a small first print, keeping the model solid avoids that additional task.

Run the available error checks before exporting. Model repair addresses problems with the model’s surfaces; it doesn’t decide whether your supports will hold. Overhang detection highlights areas that may need support before slicing. Island detection checks sliced layers for areas with nothing attaching them to the previous layer. Inspect those findings instead of deleting every flagged island, which could remove intended detail.

Finally, examine the layer preview and confirm your resin settings. Exposure time controls how long each layer receives curing light. The wrong exposure can cause failure or lost detail even when the model preparation looks sensible. Paying for more preparation tools doesn’t remove the need to get that setting right.

Where CHITUBOX can slow you down

Separate the waits you encounter. Rotating a crowded scene, generating supports, slicing layers, and saving the finished file are different jobs. An improvement in one doesn’t establish an improvement in the others.

A reported 2021 comparison found stuttering scene movement in both Basic and Pro on a quad-core Core i5 computer with 8GB RAM. Support generation and cutting operations also involved waits. That was old software on a machine below today’s documented RAM minimum, so it doesn’t tell you how version 1.3.0 will run.

Support generation still depends on model complexity. Some optional operations add work of their own: CHITUBOX specifically cautions that checking symmetry for Mirror Support can take time on complex models. Skip that check when the object isn’t symmetrical. A feature that reduces manual effort can still require a processing wait.

Slicing speed is a separate consideration. Don’t choose CHITUBOX expecting a proven speed advantage over Lychee. Saving a minute on your computer wouldn’t necessarily shorten the print, either: physical printing time depends on the layers, exposure, and machine movements.

Saving and reopening matter more than a smooth-looking preview. Save the editable project before major changes, then reopen the exported slice file and inspect it. If you’re using USB transfer, saving to your computer before copying gives you a local copy to check.

Older Basic also offered Replace Model to keep supports when importing a slightly revised model. Check that those supports still touch the right places after the shape changes. If your setup can’t reliably save, reopen, or export your work, resolve that before using it for important jobs. Individual owner complaints don’t tell you how common those problems are in current installations.

How CHITUBOX compares with Lychee

Lychee is the closest useful alternative to try when CHITUBOX’s support editing feels awkward or a needed control requires payment. It also has subscription limits: the current names are free Lychee Lite and paid Lychee Plus, rather than the Free/Pro labels used in many older guides.

Lite includes core preparation and export, with ads on export and limited tools for organizing multiple print plates in one project. Plus adds tools such as support painting and more extensive 3D hollowing, and removes export ads. Its 30-day trial lets you assess those tools before subscribing. Check what remains available when that trial ends.

For detailed figures, support painting is worth exploring because it lets you target areas instead of placing every support individually. CHITUBOX also offers tools for adding supports to selected areas. Compare how easily you can reach an awkward underside, correct a contact, and inspect the result in each program.

Try the same model in both, using your actual printer and comparable settings. Check the required output format first, then compare the effort involved in fixing supports and reopening your saved work. Neither interface is automatically easier for every beginner, and the available comparisons don’t establish a current speed or reliability winner.

If you’re starting resin printing in 2026, choose a slicer that exports files your printer accepts and makes corrections easy to understand. CHITUBOX isn’t a general replacement for Cura, whose main job is preparing filament prints. Choose software for your type of printer before comparing convenience features.

Should you choose CHITUBOX?

I recommend trying CHITUBOX free if your printer is supported and you want to learn resin preparation without immediately adding a subscription. Complete a small job, including saving and reopening it, before committing a complicated model to the workflow.

If you’re comfortable with older Basic, identify what you actually need from the unified app before switching. A new printer’s required output may justify the move; an unfamiliar version number alone doesn’t. Keep copies of your projects and settings while checking compatibility.

Consider paid access when you’ve found a task you do often that its controls make easier. Confirm the subscription includes those controls and that they work with your files. Don’t pay for Pro simply expecting better prints or faster slicing.

Try Lychee if support correction remains frustrating. CHITUBOX’s appeal is the combination of preparation tools and broad printer support. Its limitations are the judgment still needed to prepare a print and the care required when translating old Basic/Pro advice into today’s plans.
