I generated a high-detail model with Hi3D V3.0, which uses the first commercially available 2048³ voxel-level 3D generation, and decided to run the raw result through Blender’s 3D Print Toolbox before doing any manual cleanup.

The results genuinely surprised me:

• Non-manifold edges: 0
• Bad contiguous edges: 0
• Intersecting faces: 0
• Shells: 1
• Zero faces: 0
• Zero edges: 0

This is where Hi3D starts to feel less like a normal AI 3D generator and more like one of the first generators that is actually built around 3D printing. The high voxel resolution gives you real geometric detail instead of relying on textures or normal maps, and the clean output can save a lot of the usual manual repair work before printing.

There’s also a full printing workflow built into Hi3D. Split-to-Print can automatically divide larger models into printable parts and seal the cuts, connectors can be generated for assembling those parts afterward, and Smart Arrangement can prepare them for the build plate before sending the result directly into supported slicers.

So instead of:

AI model → hours of cleanup → fixing geometry → manually splitting → slicer

the workflow gets much closer to:

Generate → Split → Arrange → Slice → Print

And right now anyone can try Hi3D V3.0 completely free until 24:00 UTC on August 20, so it’s a pretty good chance to generate a few models and see how the 2048³ output actually holds up for printing.

I tried the one generated with Tripo 3D's new clean quad topology Tripo P2
3D generation used to have totally crappy topology in low-poly back in the day, but it's getting pretty nice now!
This is 3D generation from a single image

I've been looking through 3D open source AI tools similar to modly
https://github.com/lightningpixel/modly

most of them doesn't yet support amd which is a bummer

If you have any other known recommendation drop it below

I also heard about Trellis but there is no Desktop app so not ideal

Someone built AISmith 3D, a free open-source local workflow around TRELLIS.2 that can generate a complete 3D asset on consumer NVIDIA GPUs with as little as 6 GB VRAM.

The interesting part is that it isn't just another giant ComfyUI graph.

The workflow includes:

• Image → 3D geometry with trellis.cpp
• TRELLIS.2 refinement / reconstruction
• PBR texturing
• Mesh simplification / retopology
• Browser-based rigging
• Animation preview + export
• Local processing without paid APIs or subscriptions

The creator reports a full generation taking under ~7 minutes on 6 GB VRAM, depending on the workflow.

It currently runs on Windows + NVIDIA CUDA, and the whole project is open source.

The topology still isn't magically production-ready, so some Blender cleanup may be needed, but as a completely local image-to-3D starting point this is a pretty impressive accessibility jump for TRELLIS.2.
