Come l'Altezza del Strato Influenza la Resistenza delle Stampe 3D
Scopri come l'altezza del strato influisce sulla resistenza meccanica delle stampe 3D FDM e impara a ottimizzare le tue impostazioni per ottenere risultati migliori.
Quick answer: a small PLA part (up to 50 g) costs between $1 and $3 to produce in 2026, including filament, energy and machine wear. In resin, a 30 ml miniature runs $2 to $5. Below is the full math — and at the end you can calculate the exact cost of your part.
Cost per gram (rule of thumb)
PLA filament averages $15–25 per kilo in 2026, i.e. $0.015–0.025 per gram of material. But the real production cost — adding electricity, printer depreciation and a failure reserve — lands around $0.04 to $0.07 per gram.
Practical examples with 2026 numbers
- Keychain (10 g, ~40 min): $0.40–0.80 cost → sells for $3–5.
- Phone stand (40 g, ~3 h): $1.60–2.50 cost → sells for $5–10.
- Resin RPG miniature (15 ml, ~4 h): $1–2 cost → sells for $8–15.
- Large cosplay part (800 g, ~40 h): $30–50 cost → sells for $100–200.
How much does a 3D printer cost in 2026?
Prices have dropped a lot. Figures below are Brazilian retail (the links go to Amazon Brazil), checked on 30 Jul 2026:
- Entry FDM (Creality Ender-3 V3 KE): ~R$ 2,200 — great for learning.
- Plug-and-play FDM (Bambu Lab A1 + AMS Lite (Combo)): ~R$ 4,700 — fast, quiet, just works. The bare A1, without the AMS, runs ~R$ 3,200.
- Enclosed production FDM (Bambu Lab P1S + AMS (Combo)): ~R$ 8,300 — ABS and multi-material. The bare P1S runs ~R$ 7,100.
- Entry resin (Elegoo Mars 5 Ultra 9K): ~R$ 2,600 — 9K detail for miniatures.
- Large resin (Elegoo Saturn 4 Ultra 16K): ~R$ 3,900 — volume + 16K resolution.

FDM or resin: which is cheaper?
FDM is cheaper per part: PLA goes a long way and there are no extra consumables. Resin costs more ($30–50 per liter, plus alcohol and FEP film), but delivers detail FDM can't match — which is why resin miniatures sell at higher margins.
How much should you charge for a 3D print?
The maker-market rule: total cost × 1.5 to 2.0 (50–100% margin). Add your modeling/finishing time and shipping. Custom or urgent parts justify higher multipliers.
