Whether you run an Etsy 3D printing store, manage a high-throughput print farm, or run a desktop CNC router, in short, our tools calculate exact material costs, electricity, tare weight deductions, and cutting parameters.
Fabrication Calculators Quick Reference Matrix
| Calculator | Primary Inputs | Underlying Formulas | Key Output Metric |
|---|---|---|---|
| Print Cost & Pricing | Filament grams, print time, kWh rate, labor | 4-Pillar Quoting Model + Failure Buffer | Total job cost & retail price ($) |
| Filament Usage & Meters | Filament weight, material type (PLA/PETG) | Mass & Specific Gravity Density ($V = m/\rho$) | Length (m) & Benchy yield count |
| Spool Remaining Weight | Gross weight on scale, brand/spool type | Gross weight minus verified tare weight | Net filament grams & meters left |
| CNC Feeds & Speeds | Endmill diameter, flutes, material SFM | $RPM = (Vc \times 1000) / (\pi D)$, $F = RPM \times z \times fz$ | Spindle RPM & Feed Rate (mm/min) |

3D Print Cost & Price Calculator ⭐ (Flagship)
Calculate total production costs including filament weight, electricity kWh, machine depreciation wear, labor, and print failure buffers. Generates suggested retail pricing with customizable profit markups.
🧵
Filament Usage & Length Calculator
Convert spool weight to exact linear meters and feet for PLA, PETG, ABS, ASA, TPU, and Nylon. Includes realistic 3DBenchy and part benchmarks for 1.75mm and 2.85mm filaments.
⚖️
Spool Remaining Weight & Runout Check
Avoid mid-print failure. Deduct the empty spool tare weight (with presets for Bambu Lab, Polymaker, eSUN, Prusament, Sunlu, and Hatchbox) to confirm if you have enough grams left for your slicer estimate.
⚙️
CNC Feeds & Speeds Calculator
Calculate optimal spindle RPM, feed rate (mm/min or IPM), plunge rate, and depth of cut for softwoods, hardwoods, acrylics, and aluminum 6061 without burning workpieces or snapping end mills.
