3D Printed Part Cost with accepted part quantity of 40 parts: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop accepted part quantity to 40 parts, then walk the calculation through step by step. Estimate total printed-part cost from batch quantity, variable cost per part, setup labor, and overhead burden.

The inputs for this scenario

  • Accepted part quantity: 40 parts (the input this scenario stresses; the baseline uses 80)
  • Variable cost per part: 18.5 $ / part (held at the documented default)
  • Setup and labor cost: 240 $ (held at the documented default)
  • Overhead and burden: 160 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable part cost = accepted quantity × variable cost per part.
  • Total printed part cost works out to 1,140 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per printed part works out to 28.5 $ / part at these inputs.
  • Variable part cost works out to 740 $ at these inputs.
  • Setup and overhead adders works out to 400 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where accepted part quantity sits at 80 parts and the headline result is 1,880 $, this scenario comes in 39.36% below the baseline at 1,140 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to accepted part quantity, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a flat overhead and setup figure for the whole job; it does not model post-processing steps, support removal labor, or scrap from failed builds unless you fold those into the inputs.

Results at a glance

  • Total printed part cost: 1,140 $ (headline result)
  • Cost per printed part: 28.5 $ / part
  • Variable part cost: 740 $
  • Setup and overhead adders: 400 $
