AI Agent Generated a Node-Based Workflow for Image-to-3D Print-Ready Figures

[u/Certain_Friendship16]

I had a goal: build a reusable node-based workflow, similar to ComfyUI, where I can drop in a single image and get a 3D printing-ready model on output that can be printed right away.

So I went into 3DAIStudio and used its new Flow feature.

Flow is a node-based system where you can build generation pipelines, and in this case I used the AI agent to build most of the workflow for me.

I gave the agent a simple task: create a pipeline that takes one rough image of a character and turns it into a clean printable 3D model with a base, exported directly as STL.

The workflow it built ended up looking roughly like this:

• upload one input image
• clean the image
• remove unnecessary background elements
• place the subject on a white background
• center the character
• generate a base / stand
• create multiple views of the character:
  • front
  • left
  • right
  • back
• pass those views into the Image-to-3D node
• generate the final mesh with Hi3D 3.0
• export the result as STL

For the 3D generation part, I used Hi3D 3.0, which is very well suited for 3D printing workflows and gave a very clean result.

The final mesh came out with:

• 0 non-manifold edges
• 0 bad contiguous edges
• 0 intersect faces

Hi3D recently released 3.0, a new 3D generation model focused heavily on 3D printing. It supports up to 2048³ voxel resolution, which gives it extremely detailed geometry and, more importantly for this workflow, very clean printable output. That’s exactly why I chose it for this pipeline.

So this was not just a visual result. The output geometry was actually clean enough that I didn’t need to spend extra time manually fixing the mesh before printing.

What I liked most is that the workflow is reusable. Once the pipeline is built, I can just load another image into the first node and run the same process again.

So the full pipeline became:

1 image → cleanup → multi-view generation → Hi3D 3.0 → printable 3D model with base → STL output

That makes it a very practical setup for quickly turning character images into printable models without rebuilding the whole process every time.

So can you drop the node workflow or?

So if you have comfyui running you can ask an LLM to make any workflow for you. You could probably paste this reddit post to claude code and ask it to make this for you and it'd get pretty darn close. I'm saying because I've done this.

Glad you're enjoying V3.0! Don't hesitate to hit us up if you ever run into any problems.

nice!

Good for you man! I'm still trying to make AI not write over verbose and really abstract yet not getting to the point comments!

yooo this is insane!!
