Free 3D Printing Calculators & Tools

Q: "Are these calculators really free?"

"Yes! All calculators are 100% free with no registration, no ads, and no hidden costs. They run entirely in your browser for privacy."

Q: "How accurate is the FDM Cost Calculator?"

"Very accurate! It accounts for filament cost, electricity (based on printer wattage and local rates), print time, and optional depreciation. Many users report within 5% of actual costs."

Q: "Can I suggest a new calculator?"

"Absolutely! Contact me at minimal3dp@gmail.com or comment on YouTube with your ideas. I\u0026amp;rsquo;m always looking to add tools the community needs."

Q: "Do the calculators work offline?"

"Once loaded, yes! The calculations happen entirely in your browser, so you can bookmark the page and use it offline."

Reference Guides

Nozzle Lifespan Reference Guide

Nozzle lifespan depends on the nozzle material and the filament being printed. Abrasive filaments (carbon fiber, glow-in-the-dark, wood-fill) will destroy brass nozzles very quickly.

Nozzle Material	Filament Type	Est. Lifespan (kg)
Brass	Standard (PLA, ABS, PETG)	10 - 25 kg+
Brass	Abrasive (CF, Wood, Glow)	< 1 kg (as low as 0.25 kg)
Stainless Steel	Standard & Light Abrasive	20 - 50 kg+
Hardened Steel	All, incl. Heavy Abrasive	50 - 100 kg+
Ruby / Nozzle X	All, incl. Heavy Abrasive	100 kg++

Nozzle Size Reference Guide

Nozzle diameter (size) is a trade-off between print speed and detail.

Nozzle Size (mm)	Typical Use Case
0.15 - 0.25	Extreme detail (e.g., miniatures), very slow. Prone to clogging.
0.40 (Standard)	Best all-around balance of speed and detail. Default on most printers.
0.60	Faster prints, stronger parts. Good for abrasive filaments. Loses fine detail.
0.80 - 1.00+	Very fast "draft" prints or large structural parts. Very low detail.
