Additive Manufacturing worked example

Resin Cost Per Part with total resin cost of 48 $: a worked example in additive manufacturing

This worked example runs the resin cost per part numbers for a tougher week than the baseline: total resin cost of 48 $ instead of the typical 96 $. Calculate photopolymer resin cost per accepted part from total resin cost and good part count.

The inputs for this scenario

  • Total resin cost: 48 $ (the input this scenario stresses; the baseline uses 96)
  • Accepted resin parts: 24 parts (held at the documented default)
  • Cost conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw resin cost per part = total resin cost รท accepted resin parts.
  • Resin cost per part works out to 2 $ / part at these inputs, and this is the headline figure for the scenario.
  • Raw resin cost per part works out to 2 $ / part at these inputs.
  • Cost conversion factor works out to 1 x at these inputs.
  • Accepted resin parts works out to 24 parts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where total resin cost sits at 96 $ and the headline result is 4 $ / part, this scenario comes in 50% below the baseline at 2 $ / part.
  • Use it when quoting SLA/DLP/MSLA jobs, comparing resin chemistries, or measuring how failed builds raise effective material cost. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Resin cost per part: 2 $ / part (headline result)
  • Raw resin cost per part: 2 $ / part
  • Cost conversion factor: 1 x
  • Accepted resin parts: 24 parts
