3D Gear Generator
Design spur, helical, internal and planetary gears in real time and export STL, 3MF and DXF files ready for 3D printing.
Want it printed with precision?
Upload your file: we print it in our specialized lab with ±0.05 mm tolerances.
How the 3D Gear Generator Works
The tool mathematically computes the precise involute tooth profile to ensure smooth and silent meshing. Configure module, tooth count, pressure angle (typically 20°), face width, and backlash compensation specifically tailored for FDM and SLS 3D printing.
Recommended Polymers for Gears
For high-friction mechanical gears we recommend Nylon PA12 or PA-CF (carbon fiber reinforced), offering outstanding wear resistance and thermal stability. For medium loads, PETG and PETG-CF provide high rigidity and dimensional accuracy.
Frequently Asked Questions
Can 3D printed gears be used in real mechanical assemblies?
Absolutely. With proper layer orientation and self-lubricating technical polymers (such as Nylon PA or POM) or carbon-reinforced composites, 3D printed gears withstand thousands of operating hours in gearboxes, actuators, and robotics.
How is the 3D printing price calculated?
Pricing is calculated in real time based on actual volume (cm³) and chosen polymer (PLA, PETG, Nylon, Carbon Fiber). Shipping and taxes are transparently handled at checkout.
Which 3D CAD formats can I export for free?
You can export watertight STL files, 3MF files with material metadata, DXF/SVG vector profiles for laser cutting, and full engineering PDF datasheets.
