Estimate 3D print cost from slicer weight or filament length, spool price, print time, electricity, labor, waste, quantity, and markup.
Use the material use and print time reported by your slicer.
Used only when converting filament length to weight. Check your spool or material data sheet if it differs.
Built-in materials stay unchanged. Save edited values as a new material.
Start with the weight or length from your slicer. That keeps the calculator grounded in the actual toolpath.
Add a waste allowance for supports, purge, trimming, and failed attempts. Increase it when the part is risky or material is expensive.
Machine rate, setup time, finishing time, and markup are optional. Leave them at 0 for a simple hobby estimate.
Choose the mode that matches your slicer output. Length mode needs the right filament diameter and density.
Electricity prices vary by location. Use your own rate when a long print or print farm quote needs a tighter estimate.
Customer quotes often need time for setup, removing supports, cleanup, packing, and failed attempts.
Save density, spool cost, and spool weight for filaments you use often, then pick them from the Material drop-down.
Machine time covers printer wear or shop overhead. Labor covers hands-on setup and finishing.
Print time depends on layer height, speed, supports, travel moves, warmup, and the slicer profile.
A 60 g PLA print with 10% waste on a $24 spool costs about $1.65 before labor or markup.
Eight 25 g PLA parts with labor, machine time, waste, and 30% markup come to about $4.41 per item.
