Meshy vs PartCrafter

Meshy creates 3D assets from text, images, or creative concepts for users to preview, edit, and export. Text-to-3D generates textured models from written descriptions, while Image-to-3D works from photos, sketches, or concept art. It can auto-rig humanoid and quadruped characters and offers more than 600 motion presets. For 3D printing, Meshy says its models are watertight and manifold; its printability check scans exports and can repair some edge cases. Integrations include Blender, Unity, Unreal Engine, Godot, Roblox Studio, Bambu Studio, OrcaSlicer, and Creality Print, along with a REST API and MCP server. The Android and iOS app syncs with the web app and exports formats including STL, GLB, FBX, OBJ, USDZ, and 3MF. The web app has a 100 MB upload limit for AI texturing and accepts one model at a time. Meshy has a free plan; Pro starts at $20 a month. Free-plan assets use CC BY 4.0 and require attribution for commercial use.

PartCrafter is a free, open-source model that generates multiple 3D parts and objects from a single RGB image. It can handle individual objects and complex scenes, producing distinct meshes with meaningful part structure without requiring a pre-segmented image. Its architecture represents parts with disentangled latent tokens and uses hierarchical attention to pass information within and across parts. Local inference scripts can remove backgrounds and optionally apply style transfer to adapt real-world photos toward the rendered-image domain used for training. An optional vision-language feature can suggest the number of parts; Gemini is the default provider, and the provider architecture can be extended. Pretrained object-level and scene-level weights are hosted on Hugging Face. Installation is from the GitHub repository in a Python environment, and inference requires a CUDA-enabled GPU with at least 8 GB of VRAM. The linked Hugging Face demo is paused, though its page says users can ask the authors to restart it. The repository lists an MIT license and provides the software as-is, without warranty.
