STEM Sketch

★ Flagship

Design real, fabrication-ready parts for 3D printing, laser cutting, and CNC — the perfect on-ramp to CAD production. From screen straight to your makerspace.

Grades 4–12EngineeringDesignMakerspace

STEM Sketch is a browser-based 3D design studio built for classrooms. Students create real objects in an intuitive format that builds directly on how they first learn to draw — the same orthographic thinking they practice on paper carries straight into the software. Their work exports as fabrication-ready files: STL for 3D printers, SVG for laser cutters, and paths for CNC. There's nothing to install, and a first-time user is modeling within minutes.

Under the hood it's genuinely capable — precise dimensions, boolean cuts, even threaded bolts and nuts — so the ceiling stays high for your strongest builders while the floor stays low for beginners.

The work doesn't stay trapped on a screen: export to 3D printers, laser cutters, and CNC machines, and bring students' designs into their hands.

How a class uses it

  • Start with a one-period project: a name keychain or luggage tag, designed and sent to the 3D printer the same day.
  • Level up to functional parts — hooks, brackets, boxes with fitted lids — that students measure, model, and print.
  • Run a design brief: give a constraint (must hold a phone at an angle, must fit in a 100 mm cube) and let students iterate.
  • Every design saves to the student's account, and you can see the class's work from your dashboard.
Lesson plans & projects

Teacher Pro and District plans include ready-to-teach lesson plans and projects — bringing 3D-printed and CNC-style projects to entire classrooms, not just one student at a time.
