ChituGlyph AI3D. 3D model generation directly from Chitu

I've spent a couple of weeks tinkering with ChituGlyph AI3D, the new AI generator that Chitubox has built into its slicer in version 3.3.0, and I'll be honest with you: I had my doubts. Just another "AI feature" shoehorned in, I thought. Well, I've had to eat my words, at least partly. Here's what it does well, what it does so-so, and whether it's worth updating.

The idea is simple to the point of being obvious: you type what you want to print, wait a few seconds, and the slicer spits out an STL. That's it. No jumping over to Blender, no downloading anything from Thingiverse, no wrestling with ZBrush if sculpting isn't your thing. "Medieval dragon with detailed scales" and off you go. And the most interesting part is that the AI understands our jargon — you can say "flat base" or "no extreme overhangs" and it gets it. Not always perfectly, mind you, but it gets it.

What exactly is ChituGlyph AI3D?

It's a model generation module built into Chitubox 3.3.0 that converts text prompts into meshes ready for the slicer. The important thing here isn't so much "we have generative AI" — that already exists on half a dozen websites — but rather that it lives inside the program you already use for printing. That changes the workflow in a way you don't fully appreciate until you try it.

You open Chitubox, click the AI3D button in the top bar, a side panel opens and you type away. "Human skull with articulated jaw", "stackable dice tower RPG style", "28mm orc miniature with round base". It takes between 15 and 40 seconds depending on complexity and drops the model directly onto the slicer platform, ready to orient and add support. That part — not having to export and import between five different programs — is where the real value lies.

I was surprised that it understands style modifiers: "low poly", "organic", "Warhammer style", "rocky look". Don't expect miracles with "Games Workshop Horus Heresy edition style", but with reasonable descriptions it responds pretty well. Where it falls apart, and this needs to be said clearly, is with anything requiring mechanical precision. Gears, threads, assembly tolerances... forget it. For that you still have Fusion 360 or FreeCAD, and that's how it's going to stay for quite some time.

Installation and what you need to have on hand

First things first, and this is important: earlier versions of Chitubox don't include the module. You need to download version 3.3.0 from the official website. During installation a checkbox appears that says "Install AI3D Module" — tick it. If you accidentally skip it, you can add it later through the module manager, but it's an unnecessary hassle. The installer with the module weighs about 180 MB more than usual.

As for requirements, it's not over the top but it's not trivial either. A GPU with at least 4 GB of VRAM (a GTX 1650 will do, though slowly), 8 GB of RAM, and Windows 10 or 11. On Mac it works with Apple Silicon chips (M1 onwards), and on Linux... let's just say it officially doesn't exist. I've seen people getting it to run with Wine but I wouldn't recommend it if you want to sleep soundly.

The first time you click the AI3D button the program asks you to log in to ChituBox Cloud. This is where things get a bit less friendly: generation consumes credits, and credits are tied to your Chitubox subscription plan. There's a free tier with a handful of daily generations so you can try it out, but the exact details of how many credits each plan gives you need to be checked in the official documentation, as they've been changing them every other day since launch.

A useful note: in Settings > AI3D there is a "GPU Acceleration" option that comes disabled by default on some machines. Enable it. My generation times went from almost a minute down to around 20 seconds.

What is it actually useful for, and what isn't it?

I'll spare you the marketing speech. AI shines with organic shapes and artistic concepts, and gets stuck with everything else. This isn't a one-off bug they're going to fix next week — it's the nature of the underlying model type. Once you understand that, you know where you stand.

On my test bench, what worked best were RPG miniatures, busts, decorative props, rocks, and terrain pieces. I produced a series of modular gothic columns for a Mordheim board that came out decent straight away, with a couple of tweaks in Meshmixer to clean up the base. Simple gems and rings also turn out well, although for real jewellery you'll want to refine the mesh afterwards.

A trick I've refined through trial and error: always put the size in mm at the start of the prompt and add "no internal supports" at the end. It sounds trivial, but the AI changes the geometry quite a bit when it knows the target scale, and the support note stops it from creating voids that are impossible to drain.

Does it replace downloading STLs the traditional way?

No, and I don't think that's the right question. The point of ChituGlyph isn't to compete with MyMiniFactory or the professional Patreon sculptors — it's something else entirely: eliminating the friction between "I have an idea" and "I have something printing." When you need ten rock variations to fill a base, or a quick prop for a weekend game session, or to test a concept before putting hours into Blender, that's where the integration inside the slicer makes the difference. No need to open other programs, no format conversion, no searching for anything.

For serious projects, display miniatures, or anything you're going to print more than three times, STLs from real sculptors are still in a completely different league. There's no comparison. AI produces pleasant shapes, but the hand of a skilled sculptor shows in the small details, the proportions, the visual narrative of the figure. That, for now, nothing replaces.

My workflow ends up being hybrid: I generate a base concept with ChituGlyph, export it to Meshmixer to clean up the mesh and fix any topological damage, and if it's a mini I'm interested in I take it into ZBrush to add detail where it matters. It sounds like more steps but it actually saves me the work of blocking out shapes, which is always the part I dread most.

Frequently asked questions

How many credits does the free version include?

It depends on the Chitubox subscription plan, and the exact details have been shifting since launch. Your best bet is to check the official documentation before signing up, because whatever any blog says — including this one — could be out of date within a week.

Can I export the models to other programs?

Yes, they come out as standard STL files and anything can open them. That said, the file comes with the orientation and support settings that Chitubox has applied, so if you bring it into Blender you'll probably want to regenerate them there.

Does it work without an internet connection?

No. The generation is processed on Chitubox's servers, not on your PC, so without internet there's no AI. The rest of the slicer works normally, of course.

Is it compatible with all resin 3D printers?

The STL files it generates are universal, so yes. Chitubox 3.3.0 maintains compatibility with Elegoo, Anycubic, Phrozen and pretty much everything you'll find on the market.

So, is it worth it?

If you regularly print miniatures, props or scenery, yes, even if just to try it out. Version 3.3.0 is free and the trial credits are enough to get a clear idea of whether it fits into your workflow. If your thing is technical parts, gears or items with tolerances, save yourself the download — this isn't for you, at least not yet.

What I am clear on is that the direction is the right one. Integrating generation inside the slicer rather than leaving it as yet another loose web service is the kind of move that, looked back on in a couple of years, will seem obvious. Chitubox got there first and that counts. Things still need polishing — the credit management is a bit confusing, the module demands more VRAM than it should, and the results still need to go through a mesh editor if you want something serious — but the core of it works.

My recommendation: download it, spend the free credits on something silly (a cat in armour, whatever) to get the hang of the prompts, and from there decide whether the leap is worth it for you. And if you go for it, let me know how it goes in the group.
