Scale: The Foundation of 3D Printing
[!WARNING]
Getting scale wrong is the #1 reason prints fail or come out the wrong size. Always double-check dimensions before printing!
The Standard: Millimeters
All 3D printing uses millimeters (mm) as the standard unit.
| Object | Typical Size |
|---|---|
| Keychain | 30-50mm |
| Phone Stand | 60-120mm |
| Figurine | 50-100mm |
In Our Editor
- 1 unit = 1 cm = 10 mm
- A 2×2×2 cube = 20mm × 20mm × 20mm
[!INFO]
The Print Readiness panel automatically shows dimensions in millimeters, so you can verify sizes before exporting.
Print Volume Limits
Most FDM printers: 220 × 220 × 250 mm
The Print Readiness panel will warn you if too large!
[!TIP]
If your model is too large, you can scale it down or split it into multiple parts that can be assembled after printing.
