3D Print Time Calculator

Estimate 3D print time and number of layers from model dimensions and print settings.

How to Use the 3D Print Time Calculator

  1. Enter model height and layer height in mm.
  2. Enter print speed in mm/s.
  3. Enter model volume in cm³ and click Calculate.

使用例

計算式

Formula: Time = Volume / (Speed × Layer Height × Nozzle Width). Layers = ⌈Model Height / Layer Height⌉.

よくある質問

Why is the estimate different from my slicer?
Slicers account for acceleration, travel moves, retractions, and cooling. This calculator gives a quick theoretical estimate.
What print speed should I use?
Standard PLA prints at 40–60 mm/s. Higher speeds like 100+ mm/s are possible with optimized settings and modern printers.
How does layer height affect print time?
Doubling layer height roughly halves print time but reduces detail. Common layer heights are 0.1mm (fine), 0.2mm (standard), 0.3mm (draft).
