When will my 3D print finish if I start now?
Enter the current time in Start At mode and your slicer's estimated duration. The calculator instantly shows your finish time. For a 6-hour print starting at 2 PM, it finishes at 8 PM.

How to Calculate Delay Start Time
How accurate are 3D print time estimates?
Modern slicers (Cura, PrusaSlicer, Bambu Studio) are typically accurate within 5-10% for well-calibrated printers. Factors like retraction frequency, travel moves, and acceleration settings affect accuracy. Add a 10% buffer for critical timing.
Should I start a long print overnight?
For prints over 8 hours, calculate if it finishes at a convenient time. A 12-hour print started at 10 PM finishes at 10 AM - perfect if you work from home. Use our calculator to find the ideal start time for your schedule.
How to calculate multiple 3D print queue times?
Use the calculator for each print sequentially. Print 1 finishes at 3 PM → start Print 2 at 3 PM (allow 5 min for plate swap and preheat) → enter 3:05 PM as start for Print 2, and so on.
Does print time include bed heating?
It depends on your slicer settings. Cura and PrusaSlicer typically include heating time. Bambu Studio shows separate 'preparation' time. Check your slicer's time breakdown to know what's included.
About This Calculator
Why 3D Print Timing Matters
Unlike appliances with simple cycles, 3D prints can run for hours or even days. Knowing exactly when your print will finish helps you:\n\nPlan collection: Be there when it finishes to start the next print or remove it before it cools unevenly.\n\nAvoid overnight failures: Calculate if a print will finish before you need to sleep, or plan to start it so it completes mid-morning.\n\nQueue multiple prints: Schedule your print farm efficiently by knowing when each printer will be free.
How to Use This Calculator
1. Get Slicer Estimate: Your slicer (Cura, PrusaSlicer, Bambu Studio, OrcaSlicer) shows estimated print time after slicing.\n\n2. Enter Start Time: Use Start At mode with the time you're beginning the print.\n\n3. Enter Duration: Input the slicer's estimated time in minutes (e.g., 4h 30m = 270 minutes).\n\n4. Get Finish Time: See exactly when your print will complete, including if it runs into the next day.
Accounting for Print Time Variables
Slicer Accuracy: Estimates are usually within 5-10% for well-calibrated printers. Add 10% buffer for safety.\n\nFirst Layer: Complex first layers or bed adhesion issues can add 5-15 minutes.\n\nFilament Changes: Multi-color prints with AMS/MMU add time for filament swaps. Check your slicer's breakdown.\n\nPrinter Warm-up: Bed and nozzle heating (5-15 min) may or may not be included in slicer estimates - check your settings.
