Resin
Hollow Model Resin Savings Calculator
Quantify whether hollowing meaningfully reduces resin use before you trade material savings for drains, supports, and post-processing.
How the calculation works
Saved resin = (solid volume − hollow volume) × quantity. Saved cost = saved resin ÷ bottle volume × bottle price.
How to use this result
Hollowing is not automatically better for every part. Account for wall thickness, drain holes, trapped resin, strength, orientation, and cleaning access before treating material savings as a final design decision.
Example
A model reduced from 180 ml to 75 ml saves 105 ml per print before multiplying by the run quantity.
