Additive Manufacturing (FDM) Simulator — Layer Height, Flow & Filament Interactive

Follow an XY gantry depositing a rectangular thin-wall part. A filament spool feeds a hot end, the nozzle traces each perimeter, and visible roads accumulate with layer height and flow demand.

About the Additive Manufacturing (FDM) Simulator

Follow an XY gantry depositing a rectangular thin-wall part. A filament spool feeds a hot end, the nozzle traces each perimeter, and visible roads accumulate with layer height and flow demand.

What the simulator shows

• A 3D process cutaway of an FDM gantry, nozzle deposition, material flow and filament length, with labeled components you can select. • Controls: Deposition travel speed (20-80 mm/s), Layer height (0.2-0.4 mm), Number of layers (2-12 ), Nozzle temperature (160-240 °C), Filament available. • Live readouts: Current layer; Completed build height; Deposited volume; Equivalent Ø1.75 filament consumed; Commanded material flow; Toolpath completion. • Three guided experiments (No filament, Cold nozzle, Larger layers), a built-in model verification check, a timestamped event log, a trial report and a short knowledge check.

Equations used

Perimeter length = 2(30+20)=100 mm Material flow = 0.45 × layer height × travel speed mm³/s Filament length = deposited volume / [π(1.75²)/4] One animation second = 0.25 process seconds.

Model limits

Single-wall constant-width deposition without infill, retraction, acceleration or bed adhesion physics. Extrusion is simply enabled above an illustrative temperature threshold; this is not a recommended temperature for a particular polymer. Layer dimensions are visually exaggerated. Dimensions, motion and process time are enlarged where stated for explanation. These are educational models, not machine programs or qualified production procedures.

Frequently asked questions

Does moving the nozzle guarantee deposition?

No. Feedstock and an enabled extrusion condition are also required.

Does the model include infill?

No, it prints a thin wall. A rectangular perimeter isolates layer-by-layer construction.

What does the Additive Manufacturing (FDM) simulator not model?

Single-wall constant-width deposition without infill, retraction, acceleration or bed adhesion physics. Extrusion is simply enabled above an illustrative temperature threshold; this is not a recommended temperature for a particular polymer. Layer dimensions are visually exaggerated. These are educational models, not machine programs or qualified production procedures.
