What it is

What is Calc3D?

Calc3D is a free 3D printing cost and price calculator for shops that sell printed parts. It turns filament, energy, machine wear, labor, failures, and target margin into a selling price you can defend — before the quote goes out.

Who it is for

Solo makers and small 3D print shops in the US who price custom parts, short runs, and marketplace orders. If you have been charging by gram or guessing from a competitor’s Instagram, this is the working method.

  • Price every part from filament, energy, machine time, labor, and failure risk.
  • Protect margin before the quote leaves the shop.
  • Compare one piece against a batch without a second spreadsheet.
  • Save the number as a branded PDF once you create a free account.
  • Run sales, production, and inventory on PRO when the calculator is not enough.

How it works

  1. 1

    Enter the job

    Weight, print time, material, energy, labor, and the margin you actually need.

  2. 2

    See true cost

    The calculator splits filament, machine wear, electricity, finishing, and failure reserve.

  3. 3

    Send a defensible price

    Leave with a unit and batch price you can explain — then save it in the app if you want.

Why Calc3D

$6 in filament. $52 on the quote.Where did the rest go?

Charging by gram alone hides machine hours, energy, your time, and failure risk. The right method protects margin — before the customer sees the price.
