Hi3D V3.0 is out, and probably the most interesting part of the release is the jump to 2048³ voxel-level reconstruction.

Hi3D claims this is the first commercially available AI 3D model to reach this resolution. Previous Hi3D models topped out at 1536³, so the main improvement here isn't just higher-poly output, but preserving much smaller details directly in the geometry: engravings, wrinkles, thin parts, sharp edges and small mechanical forms.

They've also upgraded a few other areas that matter quite a bit for image-to-3D:

• 2048³ geometry reconstruction
• Better handling of hidden/back-side geometry and complex structures
• Up to 8K textures
• Improved UV completion
• PBR materials
• More focus on print-ready geometry and complex thin structures

I've been looking at some of the comparison examples against Meshy, Rodin and Tripo, and the geometry detail is probably the part I'm most interested in testing properly.

At this point AI 3D generators are already pretty good at making something that looks convincing from a distance. I'm much more interested in whether these higher-resolution models actually preserve details when you remove the textures, zoom into the raw mesh, and try to use the result for printing or further 3D work.

I'll probably run some identical inputs through V3.0 and a few other generators to see how much of the 2048³ advantage actually survives into the final mesh.

I used:

1. Nano banana (built-in version) to generate the picture
2. Hi3D V3.0 to convert 2D picture into 3D printable model
3. BambuStudio to hollow + drain holes + supports + slice

I’ve been working on a small free project called FlashFit AI, mainly for the Flashforge Adventurer 5M.

I started it because I was tired of changing many slicer settings every time depends from the model, filament and quality I wanted. The idea is simple: you load an STL, OBJ or 3MF file, choose the material and quality, and the app analyzes the geometry before preparing settings for that specific model.

It checks things like dimensions, overhangs, small details, separate parts and proportions. Then it adjusts speed, acceleration, walls, infill, supports, cooling and adhesion.

I honestly don’t know yet how useful it will be for everyone, but it works pretty good in my tests, so I decided to share it and maybe it can help other Adventurer 5M users too.

The macOS Apple Silicon version is currently the most complete and polished one.

The Windows 11 version is still in alpha. It works, but the interface and some parts are still rough and I’m actively improving it.

For now it supports the Adventurer 5M with a 0.4 mm nozzle. In future I want to add support also for other Flashforge printers and later printers from other brands.

It’s free at the moment and I would really appreciate honest feedback, test results or suggestions. Please always check the generated project and slicing preview in Flash Studio before printing, because the project is still young and there can be some problems.

wanted to see how far I could get without sculpting the character from scratch. I made the original reference image in ChatGPT, ran it through a 3D AI generator, then cleaned the mesh up in Blender. mostly fixed the non-manifold areas, thickened the fingers and thinner cloth parts, and adjusted the pose so it would actually print.

printed it on a Bambu Lab A1 mini with a 0.2 mm nozzle, 0.08 mm layers and marble PLA. removing the supports around the hands and clothing was a pain, and the surface still needs some cleanup, but I’m honestly surprised by how much detail survived at this size.

probably going to sand, prime and paint it next. pretty fun workflow for turning a random concept into something physical.

made this little gnome artificer as an experiment with AI-assisted 3D generation and turned it into a printable STL.

I tried to keep the details chunky enough for printing while still giving him a lot of character, especially around the armor, belts, tools and little potion canisters.

generated the concept and base 3D model with AI, then cleaned up the mesh in Blender and split it into separate parts for printing.

printed it on a Bambu Lab P1S with a 0.2 mm nozzle using mostly black, white, red and purple PLA Matte. after that I did some light sanding, assembled everything and added the smallest details with acrylic paint.

really happy with how the face, cards and tiny details came out.

decided to test hunyuan3d 2.5 since it’s free. i generated an image of a small armored car, turned it into a 3d model, fixed a few minor issues in blender and printed it on an elegoo mars 5.

honestly didn’t expect the details to come out this clean. the whole process was pretty quick and i didn’t have to pay for anything.

Hey everyone!

I’ve been learning 3D printing recently, and I wanted to see if I could turn a character reference I liked into an actual physical mini, so I tried a few different image-to-3D tools.

I used the same reference image for all of them, but the results came out pretty different, especially around the face, hair, clothing, and the hammer. In the end, I went with the meshy version because the overall shape was closer to what I wanted, and it was also easier to work with afterward.

Before printing, I did some basic checking and cleanup. I mainly fixed holes, areas that were too thin, and smaller details that looked like they might cause problems during printing, especially the hair tips, fingers, hammer, and feet.

The workflow was basically:

Reference image--AI-generated model -- check/fix --thicken a few details --add supports --print --clean and paint

Printed in resin, then cleaned, assembled, and hand-painted.

This was my first time trying this kind of workflow, and the final result came out better than I expected. I was especially happy that the expression and overall feel of the original character still came through pretty well in the physical version.

Still learning, so I’m curious: when you’re printing character minis like this, what problems do you usually run into before printing? Anything you always make sure to check first?
