Estimate 3D printing filament usage in grams and meters from model volume and infill. Plan material costs and spool requirements for FDM print jobs.
Calculate optimal layer height from nozzle diameter and print quality target. Set layer resolution as a fraction of nozzle size for best FDM results.
Calculate 3D print speed settings from volumetric flow rate and layer dimensions. Set max speed within extruder and hotend flow limits.
STL/OBJ mesh volume in cm³ converts directly to ml of resin for the solid part. 1 cm³ = 1 ml.
Model resin (ml) = mesh volume (cm³)Supports add 15–40% extra resin depending on orientation and support density. Heavy supports on overhangs increase consumption.
Support resin ≈ model volume × support factor (0.15–0.40)MSLA vats need minimum resin depth (~2–3 mm) regardless of model size. Failed prints, purge, and resin stuck in vat add 5–10% waste.
Total resin = model + supports + vat minimum + waste allowanceUpdated: July 2026
Six miniatures totaling 8 cm³ with 25% supports: 8 × 1.25 = 10 ml resin. Add 15 ml vat minimum for small MSLA printer = 25 ml total per batch.
120 ml model + 30 ml supports (25%) + 10 ml waste = 160 ml. Fits in 250 ml bottle with one print; plan resin level above model height in vat.
Ring model 0.8 cm³ with light supports (15%): ~0.92 ml per ring. Batch of 20 rings ≈ 18 ml plus vat minimum — efficient use of expensive castable resin.
Most SLA prints need supports. Omitting 20–30% support allowance causes mid-print resin shortage and failed jobs.
Always filter vat resin through mesh strainer before reuse. Cured particles cause failed layers and LCD screen damage on MSLA printers.
Resin printing consumes material for both the model and support structures. This calculator estimates total resin volume from mesh volume, support density, and vat dead volume for SLA, DLP, and MSLA printers.
