Zoo
Parametric CAD with an AI assistant. Describe a part in words and get editable geometry you can export as STEP or STL.
Strengths
Trade-offs
Text-to-3D tools like Meshy make sculptures. Text-to-CAD tools make parts. Zoo’s Zookeeper assistant turns a description like “a 40 mm wall bracket with two countersunk 4 mm holes” into real parametric geometry that you can edit, dimension and export as STEP or STL.
It handles the simple, tedious parts well: spacers, brackets, plates and basic enclosures. Independent testing has found it struggles with complex mechanical geometry such as gears and manifolds, so treat it as a fast first draft, not a replacement for learning CAD.
Always measure before you print. Check the critical dimensions in the model, and print a quick test piece before committing to a long job.
Also in AI for Makers
Text-to-3D and image-to-3D generator with STL export and plugins for the major slicers, including Bambu Studio and OrcaSlicer.
Best for Decorative prints like figurines, props, ornaments and game pieces, where the look matters more than exact dimensions.
A small computer with a real GPU. Runs vision models, small LLMs and robotics stacks on-device, without the cloud.
Best for Robots, smart cameras and drones that need serious on-board AI, and learning CUDA and edge AI.
AI failure detection for 3D printers. Watches your webcam, spots spaghetti and failed prints, and pauses the job.
Best for Klipper and OctoPrint users who leave long prints running unattended.
