MANUFACTURING – 3D PRINTING (REIN LA/MLA/DLP) CALCULATOR
Resin Cost Per Part
A precise tool.
What is the Resin Cost Per Part & How does it work?
Resin‑based SLA, MSLA, and DLP printers solidify liquid photopolymer layer by layer, and the amount of resin used is directly proportional to the part’s geometric volume.
To translate volume into material cost, the resin’s density (grams per cubic centimeter) is multiplied by the part volume, giving the mass in grams, which is then converted to kilograms for pricing.
Manufacturers also account for waste and support structures, typically expressed as a percentage increase over the raw material cost, yielding the final cost per part.
C = frac{V times rho}{1000} times P times left(1 + frac{w}{100}right)
C = cost per part (USD)

Frequently Asked Questions
How do I calculate the resin cost per part?
Multiply the part’s volume by the resin’s density to get mass in grams, then convert to kilograms. Add any waste or support structure costs as a percentage.
What is the typical resin density for SLA printers?
Resin density for SLA printers is usually around 1.05 to 1.1 g/cm³.
How do I account for waste in my resin cost calculation?
Add a percentage increase (e.g., 20%) to the raw material cost to cover waste and support structures.
Can this calculator be used for MSLA printers too?
Yes, the same principles apply. Just use the specific resin density for MSLA printers, which is typically slightly higher than SLA.
What units should I use for part volume in this calculation?
Use cubic centimeters (cm³) for part volume in your calculations.
How does resin cost per part vary between SLA, MSLA, and DLP printers?
Resin cost can vary based on density differences. MSLA resins are usually denser than SLA, affecting the final cost per part.
Is there a way to reduce resin waste in my 3D printing process?
Yes, optimizing your print orientation, using supports strategically, and ensuring proper calibration can help reduce resin waste.
