3D Baskı Filament Kullanım Hesaplayıcısı

The 3D Print Filament Usage Calculator converts model volume (cm³) to grams of filament consumed and meters of filament extruded — essential for predicting whether your current spool has enough filament for a large print and for ordering replacement spools in time. Conversion uses material density (PLA 1.24 g/cm³, PETG 1.27, ABS 1.04, TPU 1.20, nylon 1.13, PC 1.20) and filament diameter (1.75mm or 2.85mm). The geometric relationship: filament is a cylinder, so length × π × (radius)² = volume, allowing conversion from extruded volume to linear meters. Why both grams and meters: spools sell by weight (1 kg standard); machines and slicers track usage in meters. A 1 kg PLA spool contains ~330 meters of 1.75mm filament (1000 g / 1.24 g/cm³ / (π × 0.875² cm²) ≈ 333 m). When slicers report 'used 124 meters' you can convert to grams (~373 g) to know how much spool remains. Conversely, a slicer reporting '180 g' equals ~60 m extruded. For PETG (denser at 1.27), 1 kg ≈ 322 m. For TPU at 1.20, 1 kg ≈ 335 m. For 2.85mm filament, lengths are ~38% shorter at same weight (larger cross-section). Most modern printers use 1.75mm; legacy Ultimaker and some industrial machines use 2.85mm. Mixing diameters causes feeder/hotend issues — match filament diameter to printer specification. Who needs this: print operators planning multi-day prints (need to know if spool will last), spool inventory managers, comparing 'cost per meter' across brands (sometimes more honest than 'cost per kg' since meters depend on density), and slicer setup validation (cross-check that slicer reports match expected values for a known volume). For makers tracking total filament consumed over time, this calculator converts model libraries' published volumes into purchasing forecasts.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

1. 1Step 1 — Get model volume from slicer estimate or CAD report (cm³)
2. 2Step 2 — Select material type — density populates automatically (PLA 1.24, PETG 1.27, etc.)
3. 3Step 3 — Select filament diameter (1.75mm standard, 2.85mm for older Ultimaker)
4. 4Step 4 — Calculator computes mass: Volume × Density
5. 5Step 5 — Computes cross-section area: π × (Diameter / 2)²
6. 6Step 6 — Computes length: (Volume × 1000) / Area in mm, then divides by 1000 for meters
7. 7Step 7 — Outputs grams, meters, and millimeters for verification

• !Forgetting waste and supports — actual usage is 5–25% higher than the model volume
• !Using wrong density for material (PLA vs PETG differ by 2.4% — small but compounds on large prints)
• !Mixing filament diameters between machines that can't accept the size
• !Not factoring in spool weight — gross weight includes spool plastic (~250g typically)
• !Calculating cost per kg when materials with different densities should be compared per meter
