3D Printer (Dental) Calculator
Print time and resin cost for dental models and guides.
About this calculator
Print Time is driven almost entirely by geometry, not by the resin, electricity, or hardware-wear inputs on this page: Total Resin for Job, Resin Cost per Liter, Platform Utilization, Electricity Rate, Printer Wattage, FEP Film Cost, Prints per FEP, and Wash + Cure Time all have zero effect on it. Only Build Height, Layer Thickness, and Layer Exposure Time determine how long the printer runs, because LCD/DLP dental printers expose an entire layer simultaneously regardless of how many models sit on the platform -- print speed is purely a function of layer count and per-layer exposure, not part count or resin volume.
Build Height dominates because it directly sets the number of layers (build height divided by layer thickness), while a thicker Layer Thickness setting reduces the layer count for the same build height and therefore shortens Print Time, the opposite direction from Build Height. Total Job Cost, by contrast, does depend on the resin, electricity, and FEP inputs the print-time calculation ignores -- so a taller, thinner-layer print that takes much longer to run does not necessarily cost proportionally more, since cost is dominated by resin volume and platform utilization rather than time on the machine.

How to Use This Calculator
- Enter Build Height (mm) and Layer Thickness for the print job.
- Input Layer Exposure Time (sec) to calculate total print time.
- Enter Total Resin for Job (mL), Resin Cost per Liter, and Platform Utilization (%).
- Set Electricity ($/kWh), Printer Wattage, FEP Film Cost, and Prints per FEP.
- Review total print cost and per-unit cost to evaluate in-house printing economics.

Frequently Asked Questions
Does Platform Utilization affect how long a print takes?
No -- Print Time is determined only by Build Height, Layer Thickness, and Layer Exposure Time, since LCD/DLP dental printers expose an entire layer simultaneously regardless of how many parts are arranged on the platform. Platform Utilization instead affects only the Wasted Platform (%) figure, describing how efficiently the build area is being used, not how long the printer runs.
Why does a thicker Layer Thickness setting produce a shorter Print Time?
Total layers is calculated as Build Height divided by Layer Thickness, so a thicker per-layer setting means fewer total layers are needed to reach the same build height, and each layer takes roughly the same fixed exposure-plus-movement time regardless of thickness. Fewer layers at the same per-layer time adds up to a shorter overall Print Time, at the cost of coarser resolution on the finished model.
Does using cheaper resin change how long the job takes?
No -- Resin Cost per Liter and Total Resin for Job affect only Resin Cost and the derived Total Job Cost and Cost per mL figures, not Print Time. Print Time is purely a function of layer count and exposure settings, so switching to a cheaper or more expensive resin at the same build height and layer thickness produces an identical print duration.
Why might a longer print not cost proportionally more?
Total Job Cost is driven by resin volume, platform utilization, electricity, and FEP film wear, while Print Time is driven by build height and layer settings -- the two are calculated from largely different inputs. A tall, thin-layer print that takes much longer to run does not necessarily use much more resin or electricity, since a small, dense arrangement of parts can consume more resin per job than a taller but sparsely packed one.
