3D-tulostuksen materiaalikustannukset

The 3D Print Material Cost Calculator computes the filament cost per model based on model weight in grams, spool price, spool weight (typically 1 kg), and waste percentage (5–15% accounts for purge towers, brims, supports, failed prints). Standard PLA averages $0.020–0.030 per gram ($20–30 per 1 kg spool); PETG $0.025–0.035; ABS/ASA $0.020–0.030; TPU $0.040–0.060; specialty materials (carbon fiber composites, metal-filled, glow-in-dark) $0.05–0.15 per gram. This calculator gives per-print material cost — essential for pricing custom orders, Etsy/Shopify listings, or comparing brand value. Get model weight from slicer estimate (Cura, PrusaSlicer, OrcaSlicer all show grams after slicing) or weigh the printed model on a kitchen scale post-print. Waste accumulates from: skirt/brim (1–3 g), purge tower for multi-color (10–30 g), supports (10–30% of model), failed prints (full waste of attempt), and color changes (purge per color). For solo prints with no supports, 5–10% waste is realistic; for complex multi-material prints with supports, 20–30%. For commercial use (Etsy shop, custom print services), material cost is typically 10–20% of total job cost. The other 80–90% covers: machine hour (depreciation + electricity $0.50–2.00/hr), labor (slicing, post-processing, packaging $5–30/hr), shipping, platform fees (Etsy 6.5% + payment processing), and profit margin (40–60% on hobby-level work, 100%+ on specialized engineering parts). Underpricing based on material cost alone is the most common first-year mistake for print-for-hire operators. For maker hobbyists: knowing material cost helps decide print-vs-buy. A 200g phone stand at $0.025/g costs $5 in filament — competitive with Amazon. A 500g organizer at $0.025/g costs $12.50 — often beats Amazon since the print is custom. Calculator helps make these tradeoffs explicit. For schools and libraries operating shared printers, charging $0.10–0.20 per gram covers material + wear + supervision and remains affordable for students.

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

1. 1Step 1 — Get model weight from slicer estimate (slice the file first; Cura/PrusaSlicer report grams)
2. 2Step 2 — Enter spool price (your actual purchase cost, not MSRP)
3. 3Step 3 — Enter spool weight (typically 1000g; sometimes 750g for premium brands)
4. 4Step 4 — Enter waste percentage (5% for simple prints, 15% for supports, 25%+ for multi-material)
5. 5Step 5 — Calculator computes cost per gram: SP / SW
6. 6Step 6 — Computes total filament used: W × (1 + Waste%)
7. 7Step 7 — Outputs cost per gram, total grams used, and total material cost

• !Ignoring waste — actual usage is 5–25% higher than model weight
• !Pricing custom prints at material cost only — should be 5–10× to cover machine time + labor
• !Forgetting failed prints — they consume material with no salable output
• !Using MSRP instead of actual purchase cost (Amazon sales, bulk discounts matter)
• !Mixing units — calculator wants weight in grams, spool weight in grams (not kg)
