From zero to first successful print.

Eight short lessons covering the CAD basics, file formats, design rules, and slicer hand-off you actually need to ship your first design. Beginner-friendly, practical, opinionated where it helps.

Read 3 lessons

CAD basics, wall thickness, and the top-10 mistakes — the floor of what avoids a failed print.

Customize a Starter

Pick a Beginner Starter on the homepage. Each one drops a real, printable design into the workspace.

Hand off to your slicer

Export 3MF, open in OrcaSlicer / Bambu Studio / PrusaSlicer, and print. The exporting lesson covers each.

Lessons

CAD basics in 4 minutes

4 min

What CAD really is, why ForgeSlicer is a gentle starting point, and the three things you'll do over and over.

Read lesson

STL, 3MF, OBJ, G-code — what each is for

5 min

Four file formats you'll see constantly. Here's exactly when to use which, no jargon.

Boolean operations — cut, combine, keep

4 min

Union, subtract, intersect. The three commands that turn LEGO bricks into actual designs.

Designing for FDM — orientation, overhangs, supports

6 min

The physics of FDM printing in 4 minutes. Knowing this lets you skip 80% of failed first prints.

Read lesson

Wall thickness — what's actually printable

3 min

Concrete millimetre numbers for FDM. Save these and you'll never print a wall that snaps in half.
