The failure buffer isn't an exact reprint probability. Here, 5% means adding 5% to the cost as a cushion — that's the current engine's logic.

A 30% markup means selling at 1.30× the cost — that's not the same as a 30% margin.

What is 3D Printing Cost Calculator?

ProntoUso's 3D Printing Cost Calculator accurately calculates 3D print costs and sale prices, factoring in sliced filament weight with purge waste, printer power draw, machine wear, labor, and profit margins via markup or target margin.

How to calculate 3D printing costs and price your prints

Calculate the true cost of filament, electricity, machine depreciation, labor, and failure risk to price your 3D prints profitably.

The five pillars of 3D printing costs

A comprehensive 3D printing quote accounts for five main cost drivers: raw material consumption (filament or resin), electricity consumed during the print, machine depreciation and maintenance per operating hour, human labor (slicing, bed prep, and post-processing), and extra hardware (threaded inserts, screws, magnets, or packaging).

Material cost and slicer waste margin

Filament cost is calculated by dividing the spool purchase price by its total weight in grams (e.g. $20 for a 1,000 g spool = $0.02/g). Always add a waste allowance (typically 5% to 10%) on top of the slicer's estimated model weight to cover purge lines, prime towers (especially for multi-color prints), support structures, and unusable spool remnants.

Machine depreciation and hourly wear rate

3D printers degrade mechanically over time and require replacement nozzles, belts, and build plates. To calculate your machine hourly rate, subtract expected resale value from the printer purchase price, add anticipated maintenance costs, and divide by the printer's total expected lifespan in operating hours (typically 2,000 to 5,000 hours).

Failure rate and reprint buffer

Even well-tuned printers experience occasional failures due to warping, power blips, or tangled filament. Adding a failure surcharge (typically 5% to 15%) across your jobs ensures that unexpected failed prints are subsidized by your overall volume without eating into your personal income.

Commercial pricing: Markup vs. Target Profit Margin

The calculator supports two distinct pricing models: Markup on cost (adding a percentage on top of production costs: Price = Cost × (1 + Markup)) or Target Profit Margin (setting your profit as an exact percentage of final sale revenue: Price = Cost / (1 - Margin)). If your job produces multiple identical parts on a single build plate, total costs and prices are automatically divided per finished unit.

Calculation formulas

Frequently Asked Questions

How do I calculate the cost of filament per gram?

Divide the total price of the spool by its weight in grams. For example, a 1 kg (1,000 g) spool costing $25.00 costs $0.025 per gram. If a slicer estimates 120 g with a 5% waste buffer (126 g effective), the raw material cost is $3.15.

How do I estimate machine depreciation and maintenance costs?

Take the initial purchase price of the 3D printer minus its estimated resale value, add estimated lifetime maintenance expenses (replacement nozzles, hotends, belts), and divide by the printer's total expected lifetime hours (usually 2,000 to 5,000 hours). For example, a $500 printer with $100 in maintenance running for 3,000 hours equals $0.20 per printing hour.

What is the difference between Markup and Profit Margin?

Markup adds a percentage on top of production cost (e.g. 100% markup on a $10 cost yields a $20 sale price). Profit Margin calculates profit as a share of the final sale price (e.g. 50% margin on a $10 cost also yields a $20 price, since $10 profit is 50% of the $20 revenue).

Why is it important to include a failure buffer?

Prints can fail due to bed adhesion loss, layer shifts, or nozzle clogs. A failure buffer (usually 5% to 15%) spreads the risk of lost filament and machine time across all completed jobs, ensuring you never lose money on reprints.

How much power does an average 3D printer consume?

A standard FDM printer (with heated bed at 60°C and nozzle at 210°C) consumes about 80W to 150W continuously during printing. High-speed enclosed CoreXY printers draw between 200W and 350W, while MSLA resin printers typically consume 40W to 80W.

How do I price a build plate that prints multiple items at once?

Enter the total number of finished pieces in the 'Pieces per job' field. The calculator calculates the entire plate's material, power, and machine time, and divides the total manufacturing cost and suggested retail price evenly across each individual piece.
