3D Printing & Prototyping
Design brackets, enclosures, adapters, and custom parts — then export STL files ready for FDM, SLA, or SLS printers. scAId's parametric approach means you can adjust tolerances with a single variable change.
What is scAId?
AI-powered text-to-CAD,
right in your browser
scAId is a free, browser-based platform that lets you create 3D models by writing code or describing them in plain English. Unlike traditional CAD software that requires expensive licenses and steep learning curves, scAId puts the power of parametric 3D design in the hands of anyone with a web browser.
At its core, scAId is an OpenSCAD-compatible editor with a real-time WebGL viewport. You write declarative code using variables, loops, and CSG boolean operations — then hit Ctrl+Enter to see your model render in milliseconds. But what makes scAId unique is its integrated AI assistant: describe what you want in plain English, and the AI generates the parametric OpenSCAD code for you. It's text-to-CAD in the most literal sense.
Whether you're a 3D printing hobbyist prototyping bracket designs, a mechanical engineer sketching out quick concepts, or a student learning parametric design for the first time — scAId eliminates the friction between having an idea and holding a physical part. Write code, preview it, export the STL, print it. That's the workflow.
Zero install
Runs entirely in your browser. No downloads, no plugins, no system requirements.

⚙️
Mechanical Engineering
Sketch gear trains, housings, and assemblies using CSG booleans and precise parametric dimensions. Ideal for concept validation before moving designs to production-grade CAD systems.
🎓
Education & Learning
Teach or learn parametric design, computational geometry, and 3D modeling fundamentals without expensive software licenses. scAId runs in any browser — perfect for classrooms and remote students.
🔧
DIY & Maker Projects
Design custom tool holders, cable management clips, gadget cases, and one-off parts. scAId's template library gives you starting points, and the AI assistant helps you iterate fast.
🤖
Robotics & Hardware
Quickly model motor mounts, sensor brackets, chassis components, and custom connectors. Parametric variables let you scale designs to different actuator and board dimensions instantly.
💡
Product Design Ideation
Go from sketch to 3D concept in minutes, not hours. Use AI prompts to explore variations, then export for stakeholder review or rapid prototyping. Perfect for early-stage product development.
