Resin Usage with resin consumption rate of 21 ml / hr: a worked example in additive manufacturing

Suppose resin consumption rate falls to 21 ml / hr. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate SLA/DLP resin consumption from resin use rate, exposure run time, and resin unit cost.

The inputs for this scenario

  • Resin consumption rate: 21 ml / hr (the input this scenario stresses; the baseline uses 42)
  • Planned resin print time: 9 hr (held at the documented default)
  • Resin unit cost: 0.12 $ / ml (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Resin used = resin consumption rate × planned print time.
  • Resin used works out to 189 ml at these inputs, and this is the headline figure for the scenario.
  • Resin run cost works out to 22.68 $ at these inputs.
  • Planned print time works out to 9 hr at these inputs.
  • Resin unit cost works out to 0.12 $ / ml at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where resin consumption rate sits at 42 ml / hr and the headline result is 378 ml, this scenario comes in 50% below the baseline at 189 ml.
  • It multiplies your resin consumption rate by planned print time to get total milliliters used, then multiplies by unit cost to get the resin run cost. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

  • Resin used: 189 ml (headline result)
  • Resin run cost: 22.68 $
  • Planned print time: 9 hr
  • Resin unit cost: 0.12 $ / ml
