3D Printing Tools

Free 3D printing calculators that run entirely in your browser — filament length/weight/cost, print cost, print time, resin volume, E-steps calibration, max volumetric flow rate, shrinkage compensation, infill weight, spool remaining, layer count, nozzle settings and prints per spool. No accounts, nothing uploaded.

🧵

3D Printer Filament Calculator (Length / Weight / Cost)

Convert 3D printing filament between length, weight and cost for any diameter and material — enter one value, get the rest.

💵

3D Print Cost & Pricing Estimator

Price a 3D print end to end: filament, electricity, machine wear, labor, a failure buffer and profit margin.

⏱️

3D Print Time Estimator

Estimate how long an FDM print takes from model volume, layer height, line width and print speed.

🧪

Resin 3D Print Volume & Cost Calculator

Estimate resin volume, weight and cost for an SLA / MSLA / DLP print, including supports and cleanup waste.

📏

E-Steps & Steps-per-mm Calibration Calculator

Calibrate extruder E-steps from a measured extrusion, or compute belt and leadscrew steps-per-mm for Marlin / Klipper.

🌊

Volumetric Flow Rate & Max Speed Calculator

Find a hotend's volumetric flow in mm³/s for a layer height and line width, or the max print speed a flow limit allows.

📐

Shrinkage & Scale Compensation Calculator

Find the slicer scale % to cancel material shrinkage so your 3D printed part hits its target dimension.

🧊

Infill Weight & Filament Estimator

Estimate a 3D print's filament weight and length from model volume, infill % and wall thickness before you slice.

🧵

Filament Spool Remaining Length / Weight Calculator

Work out how much filament is left on a partial spool by weight or by measuring the wound diameter.

📚

Layer Count & Print Height Calculator

Compute the number of layers and the exact Z height of a 3D print from object height, layer height and first layer.

🔧

Nozzle Layer Height & Line Width Calculator

Get recommended min/max layer height and extrusion line width ranges for any 3D printer nozzle diameter.

🔢

Prints Per Spool Calculator

Find how many copies of a print one filament spool yields, the leftover filament and the material cost per print.
