Advanced 3D Print Cost Calculator
See what a successful FDM print really costs by separating filament, electricity, machine wear, maintenance, hands-on work, packaging and expected failures.
Open calculator →Filament Weight to Length Converter
Convert filament mass into length using its measured diameter and material density, so a weighed spool can be compared with slicer length estimates.
Open calculator →Volumetric Flow Rate Calculator
Estimate hotend throughput from extrusion width, layer height and print speed to identify demanding settings before running a physical flow test.
Open calculator →STL Geometry & Dimensions Analyzer
Measure the bounding box, triangle count and surface area of an ASCII or binary STL in your browser. Geometric volume is reported only when topology passes the stated checks.
Open calculator →3D Print Selling Price Calculator
Set a selling price that covers your unit cost and target margin. Compare the same percentage as a markup to avoid underpricing your products.
Open calculator →3D Printer Electricity Cost Calculator
Convert measured average printer power and running time into kilowatt-hours and electricity cost for a single job.
Open calculator →Printer Depreciation Calculator
Spread the purchase price of your printer over its useful operating hours, allowing for a residual value, and assign depreciation to each print.
Open calculator →Batch Printing Cost Calculator
Separate setup costs from variable unit costs and see how expected rejects change the cost of each accepted part in a production batch.
Open calculator →Failed Print Cost Calculator
Budget for unsuccessful attempts using their average loss and your observed failure rate, including partial failures that cost less than a completed print.
Open calculator →Print Farm Break-Even Calculator
Find the monthly number of paid prints needed to cover fixed costs and compare it with the operating capacity of your printer fleet.
Open calculator →Resin Printing Cost Calculator
Price a resin job from sliced model and support volume, additional resin losses, machine time, cleaning consumables and active labor.
Open calculator →Filament Cost per Gram Calculator
Turn a spool price and its net filament weight into a cost per gram, then calculate the material cost of a specific print.
Open calculator →Filament Remaining Calculator
Weigh a partly used spool and subtract its empty spool weight to estimate the remaining filament mass and length.
Open calculator →Prints per Spool Calculator
Check how many complete jobs fit on a spool after a safety reserve, with supports already included in the supplied mass per print.
Open calculator →Filament Density, Volume & Weight Calculator
Translate solid material volume into mass at your selected density. Use this for material comparisons, rather than as an infill-aware slicer estimate.
Open calculator →Multicolor Purge Waste Calculator
Estimate the filament and money spent on color-change purges, and compare that waste with the useful model mass.
Open calculator →Multi-Material Print Cost Calculator
Combine two differently priced materials into one job cost and add an explicit allowance for extra material losses.
Open calculator →Maximum Print Speed by Flow Calculator
Convert a tested hotend flow limit into a theoretical print-speed ceiling for the selected layer height and extrusion width.
Open calculator →Layer Height & Layer Count Calculator
Plan the number of fixed-height layers needed for a model, accounting separately for a different first layer height.
Open calculator →Extrusion Width & Wall Planner
Compare a target wall thickness with your extrusion width and estimate how many nominal perimeter lines are needed.
Open calculator →E-Steps Calibration Calculator
Correct an extruder steps-per-millimetre setting from commanded and measured filament movement, using a controlled extrusion test.
Open calculator →Flow Ratio Calibration Calculator
Apply the percentage modifier selected in a flow calibration test to your existing extrusion flow ratio.
Open calculator →Pressure Advance Tower Calculator
Read the pressure advance value at the best height of a linear calibration tower from its start value and increase per millimetre.
Open calculator →Shrinkage Compensation Calculator
Calculate the scale correction needed when a measured printed dimension differs from its target, and quantify the observed linear shrinkage.
Open calculator →3D Model Scaling Calculator
Preview the dimensions of a uniformly scaled model and see why its geometric volume changes with the cube of the scale factor.
Open calculator →3D Printer Build Volume Checker
Check whether an axis-aligned model fits the supplied printer dimensions with a specified clearance around the part.
Open calculator →Print Finish Time Calculator
Add a realistic buffer to a slicer duration and calculate the expected completion time in your browser’s local timezone.
Open calculator →G-Code Metadata Analyzer
Inspect supported G-code comment metadata locally, including declared print time and filament use when present, without executing motion commands.

Are the calculators free?
+
Yes. All 28 tools work without an account or a paid API.
Do you upload my 3D files?
+
No. STL and G-code files are analyzed on your device in a browser worker.
Are results measurements or estimates?
+
Calculations use your inputs. Cost and timing models depend on assumptions; flow and calibration tools still require real print tests. Every tool explains its limits.
