Less friction.
More “I made this.”

You don't need to know CAD to get started.
Teach3D makes room for experimenting, understanding, and trying again.

Native by design

Built in Rust, with native desktop tools and GPU rendering. Designed for responsive editing and efficient use of your computer’s resources.

Your computer. Your projects.

Create, save, and reopen your work locally. No account or internet connection needed to use the desktop editor.

Free to start. Free to explore.

Free for everyone. A welcoming place for young makers, families, and teachers to take their first steps into CAD.

A first project.
A small discovery.

Make a simple name tag blank. Along the way, learn how shapes, dimensions, and subtraction become a model you can hold.

  1. 01

    Start with a cube

    Set its dimensions to 60 × 6 × 30 mm to make a flat blank.

  2. 02

    Make room for a ring

    Add a cylinder, position it near an edge, mark it as a hole, and combine.

  3. 03

    Make it.

    Save your .t3d project, export STL, and open it in a slicer for 3D printing.

Small beginnings.
A bigger workshop.

The desktop editor comes first. Then more ways to learn, share, and create together.

  1. 01CURRENT

    The local editor

    Simple shapes, dimensions, holes, project files, and STL export. An early desktop experience for macOS and Windows.

  2. 02PLANNED

    More tools. More learning.

    Develop the 3D editor, refine everyday workflows, and add guided projects, lesson templates, and model examples.

  3. 03PLANNED

    A shared classroom

    A cloud platform for creators, teachers, and students: saved projects, classes, shared work, and assignments.

  4. 04PLANNED

    Ideas into models

    Explore Claude Code and third-party MCP integrations to create and edit models from text and help teachers prepare activities.

A future with AI-assisted creation. Planned integrations will connect modeling tools to natural-language workflows.

Before you
get started.

Is Teach3D free?

Yes. Teach3D is free for everyone to use. Free access does not mean the source code is open source.

Who is it for?

Kids aged 8-12 discovering 3D modeling, teachers guiding their first projects, and anyone taking their first steps into CAD. Children can explore with a teacher or adult.

Do I need an account or internet access?

No. The current editor version works locally without an account or internet connection.

Which computers can run the Alpha?

The Alpha is for macOS and Windows only. Supported architectures and installation details will be listed alongside each release when download links are available.

What does Alpha mean?

Teach3D is still in early testing. You can explore the core modeling workflow, but bugs and rough edges remain. STL import, cloud classrooms, and AI integrations are not available in this version.
