What is Extrusion?

Extrusion is a geometric operation where a two-dimensional shape is 'pushed' along a linear path to create a three-dimensional volume. It is a fundamental process in manufacturing (like 3D printing or aluminum extrusion) and CAD modeling. The volume is simply the area of the base times the length of the extrusion.

Pro Tips

Any 2D shape can be extruded: circles become cylinders, squares become prisms.
The cross-section remains constant throughout the entire length.
To find the weight, multiply the volume by the material density (e.g., Aluminium ≈ 2.7g/cm³).

Fun Facts

"Extrusion is how we get everything from pasta and Cheerios to aluminum window frames and PVC pipes."
"Most 3D prints are built layer-by-layer using a process called 'FDM' (Fused Deposition Modeling), which is a form of extrusion."
"The longest continuous extrusion process is used to make deep-sea power cables, which can be miles long."

Formula: Volume = Area × Length
