Calculator cluster
FDM hardware & mechanics
PSU sizing, bed heater watts, stepper torque and nozzle layer/width limits.
FDM hardware & mechanics
Bed Heater Power Requirement
Estimate heated-bed watts from plate size, thickness and material, target temperature, heat-up time and insulation. Covers the power to heat up in time and the power to hold temperature. °C or °F.
FDM hardware & mechanics
Nozzle Size vs Layer Limits
Get min, typical and max FDM layer height plus min/max line width from nozzle diameter using 0.25–0.75× height and 0.9–1.5× width rules of thumb.
FDM hardware & mechanics
Power Supply (PSU) Sizing Calculator
Add heated-bed, hotend, stepper and controller wattage, then apply a 20% safety margin to size a Mean Well-class PSU for a custom FDM build.
FDM hardware & mechanics
Stepper Motor Torque Requirement Estimator
Estimate the torque a stepper must deliver from moving mass, acceleration, friction or the weight on a Z axis, and a GT2 pulley or lead screw. N·cm or oz·in. First-order physics, not a motor datasheet.
