FAQ
Questions about PrintPrice
These are the short answers. How to price a 3D print is the same method written out in full. Neither page lists a spool price or a fee that the calculator does not cite.
Does PrintPrice open or slice a 3D file?
No. It does not open a 3D file, and it does not slice a model. Enter the grams of filament or the milliliters of resin the slicer reports. Include brim, raft, supports, and purge when they are part of the job.
How do I turn a filament length in meters into grams?
Use the length control on the calculator. It needs the filament diameter and the density in g/cm³ from the technical data sheet. The formula is π × (diameter ÷ 2)² × meters × density, with the diameter in millimeters. Density is left blank on purpose. 1.75 mm and 2.85 mm are common spool sizes. Use the number printed on the spool.
What is the difference between margin and markup?
Margin is profit divided by the selling price. Markup is profit divided by the cost before fees. On a $10 cost with no fees, a 40% markup is a $14 price and a 40% margin is a $16.67 price. That pair is arithmetic, not a print price. Fees then raise the price so the profit you asked for is what remains.
How do failed prints change the cost?
The failure rate is the share of attempts that do not become a sale. At 20%, each sale carries 1.25 attempts of material and electricity. The material and electricity lines are the successful attempt. The waste line is the extra 0.25 attempt, spread onto that sale. If you mark labor as time on every attempt, the extra labor is in the waste line too. If labor is only for a finished print, failed attempts do not add it.
Are taxes included?
No. Sales tax and income tax are not calculated. The result is not tax, accounting, or legal advice.
Is anything I type uploaded?
No. Entries stay in the browser tab. They are not sent to Wraith Labs Studios, and they are not saved in an account. There is no account. Reload or close the tab and they are gone. The site stores only the theme choice on your device, under the key printprice-theme.
Is PrintPrice free?
Yes. PrintPrice is free. There is no account and no payment.
Should I trust the Etsy fees and the electricity rate already filled in?
Treat them as starting points. They are copied from public pages, and the calculator names the page and the date it was read. Confirm the live Etsy rate in your own dashboard. Replace the electricity rate with the figure on your bill. The U.S. average is not your utility tariff.
The calculator is on the home page.
