Batch Printing Calculator — Time & Cost Savings
Calculate time and cost savings from printing multiple parts in one batch.
How We Calculate This
Formula
- Batches needed = Parts needed / Parts per batch (rounded up)
- Total print time (batched) = Parts needed x Single part time x Travel overhead (~1.15)
- Total batch time = Total print time + Batches x Setup time
- Total individual time = Parts needed x (Single part time + Setup time)
- Time saved = Total individual time − Total batch time
One nozzle has to lay down every part’s plastic, so the print itself scales with the total part count — a 4-up tray prints in roughly 4 single-part times, not one. Simultaneous printing adds about 5–15% travel time hopping between parts each layer. The genuine saving comes from running setup (heating, levelling, plate swap) once per batch instead of once per part: that consolidated setup is (Parts − Batches) × Setup time. When setup time is small relative to the travel overhead, the calculator may report a negative saving — meaning batching is slightly slower in pure print time but still wins on hands-on time and reliability.
Frequently Asked Questions
It saves wall-clock time and attention, but not by speeding up printing. A single nozzle still has to extrude every part’s plastic, so a tray of N parts takes roughly N times one part’s print time — plus a small inter-part travel penalty. The real saving is running setup (heating, bed levelling, first-layer checks) once per batch instead of once per part, and not having to babysit a reload between every part. If your setup time is short, batching can even be marginally slower in pure print time because of the extra travel moves.
If one part fails or detaches, it can knock over other parts and ruin the entire batch. This risk increases with print height and number of parts. For high-value prints, sequential printing may be safer.
Simultaneous prints all parts layer by layer (standard). Sequential completes one part fully before starting the next, which eliminates the risk of one failure ruining all parts but requires more Z clearance.
