Meshy Hermes Agent Plugin: From Chat Prompt to 3MF and Slicer

Meshy has put its print-preparation tools inside an AI assistant, and it’s the slicer handoff, not the model generation, that makes this different. The new plugin for Nous Research’s open-source Hermes Agent checks whether a model is printable, repairs it, scales it and exports a 3MF straight to a slicer on the user’s computer, all from a chat. For makers who can describe a part but can’t model one, that removes most of the steps between an idea and a print.

What Happened

3D Printing Industry reports that Meshy released an official plugin for Hermes Agent. It adds two skills:

• Generation: textured 3D models from text, images or multi-view references, which Meshy says are ready to rig and animate. The pitch is game development, character prototyping and digital content.
• Print preparation: checks printability, repairs common geometry problems, scales parts to real-world dimensions and exports 3MF files for single-color or multicolor printing, then sends them to a locally installed slicer.

Files save to a local folder in GLB, FBX, OBJ, STL or USDZ, and models can be previewed in the conversation. Hermes Agent picks the tools for each job, monitors progress and returns the file. Before any job runs, the user approves its credit cost.

The skills are free to install and connect through a browser sign-in with no API key. Generating models requires a paid Meshy plan and uses Meshy credits.

Why It Matters

Meshy’s argument is that 3D work has always meant a separate learning curve for each stage, from modeling and texturing to rigging and export. Moving those stages into a conversation changes the skill needed from knowing professional software to describing an idea. For printing, the repair and scaling steps matter most. Broken geometry and wrong dimensions are the usual fixes a generated mesh needs before it will print, and the announcement doesn’t show how reliably the automated repair handles them.

The plugin also continues Meshy’s strategy of living inside other companies’ platforms. In March 2026 its engine went into Bambu Lab’s MakerWorld through MakerLab, turning a photo into a print-ready file, and Meshy added multicolor texture mapping for Bambu’s AMS. xTool and Snapmaker were reported to be building tools on Meshy’s API. Autodesk took a different route with Wonder 3D, which runs its own model in its own Flow Studio platform and exports OBJ files.

Meshy has the scale to push this. It reports more than 15 million registered users, a Series B of nearly $400 million at a $1.5 billion valuation in July, and more than $100 million in annual recurring revenue in September. Stack Archive covered that funding round and Nous Research’s earlier Hermes Desktop release.

What This Means for Makers

The useful case is simple, decorative or personalized prints, such as the figurines, lamps, keychains and fridge magnets from Meshy Creative Lab that the workflow also covers. Functional parts that need exact tolerances will likely still call for CAD. Credit approval per job keeps costs visible, but every generation still spends paid credits, so iterating in chat isn’t free.
