Costing a PLA print from slicer weight

Reference preset: PLA 3D-print cost. These notes describe the original preset, not changes made in the calculator above.

This worksheet starts with an illustrative $25, 1,000 g spool. It is not a current market price: replace both values with your purchase figures. Select the correct PLA profile in the slicer and enter its total grams and time, including supports and adhesion features where used.

At that example price, filament costs $0.025 per gram. An 80 g print uses $2 of material before electricity and other costs. Because the input is already mass, the cost calculation does not need a PLA density or a volume conversion. Changing a material name alone would not change this arithmetic.

For a customer quote, switch to the selling-price mode and account for preparation, finishing, packaging, and failed attempts. Do not assume a successful first print or free operator time simply because material is inexpensive. The result is a cost estimate for the entered job, not a price list for PLA printing services.

Estimating the cost of a 3D print

Filament is only one part of print cost. Machine time, electricity, preparation, finishing, and failed attempts can all matter. Use the slicer's material weight and print time for the proposed settings, then enter the costs that apply to your own printer and workflow.

Separate per-part costs from batch costs

Check whether a field refers to one part or the whole batch. Preparation can be shared across several pieces, while finishing and packaging may repeat for each item. Use the spool's net filament mass when converting its price into cost per gram; the empty spool is not printable material.

Cost, markup, and margin are different

Cost estimates what you spend. Markup is added as a percentage of cost; margin is profit as a percentage of the selling price. Neither setting guarantees a profitable job if setup, reprints, or labor are missing. A failed-attempt allowance is a planning assumption, not a forecast of printer reliability.

Checking the material and time contributions

An 80 g part printed from a 1,000 g spool costing $25 uses $2 of filament. If a five-hour print draws an assumed average of 100 W, it consumes 0.5 kWh; at $0.20 per kWh that adds $0.10. Neither example includes machine ownership, setup, finishing, packaging, or a failed print. Those items should be entered separately rather than hidden inside the filament price.

For a batch, decide which preparation work happens once and which work repeats for every accepted part. Slicer time can change when multiple parts are arranged together, so check whether the per-part estimate still represents the planned build. A markup of 25 percent on $10 cost gives a $12.50 selling price, while a 25 percent margin requires about $13.33 before tax. Cost and price are therefore different outputs. Save the assumptions used for a quote so that a later change in spool price, finishing time, or rejection allowance can be compared with the original estimate.

Formula

Cost adds material, electricity, machine, labor, and packaging. Markup multiplies cost by (1 + rate); margin divides cost by (1 − rate).
