Print time depends on four main factors: object volume, layer height, print speed, and infill percentage. A small 50g keyring at 0.2mm layers on a Bambu A1 Mini takes roughly 1–2 hours. A large 300g vase at 0.3mm draft quality might take 6–8 hours. The estimator above covers all of these variables.
Layer height vs print time
Halving your layer height roughly doubles your print time. At 0.1mm you get fine detail but twice the layers of 0.2mm. For most functional prints, 0.2mm is the standard — it balances quality and speed well. Draft quality at 0.3mm cuts time by ~30% with a small visible quality drop.
Why faster printers save more than time
A Bambu A1 Mini at 250mm/s completes the same job as an Ender 3 at 60mm/s in roughly 40% of the time. That means less electricity per print and more jobs per day — directly improving your cost per print and potential revenue. Use the running cost comparison to see the full numbers.
