The Build Plate: Your Foundation

3D printer build plate
The build plate is the foundation where your print begins

The build plate is where your print begins.

Why Position Matters

✅ Good: Flat Bottom on Build Plate

  • Strong adhesion
  • Stable first layers
  • No supports needed for bottom

❌ Bad: Floating or Tilted

  • Print will fail
  • Wasted material
Warning
A floating object (not touching the build plate) will cause the printer to print into thin air! Always check that your model touches Y=0.

The Y=0 Rule

Objects should have their lowest point at Y = 0.

The Print Readiness panel shows warnings for floating objects!

Tip
In our editor, the grid represents the build plate. If your object appears above the grid, move it down until it's resting on it.
