Volex Labs / Forge / Heat sink generator — text to CAD.

Heat sink generator — text to CAD.

Describe the heat sink — base footprint, fin height, fin count or pitch, fin thickness and mounting holes — and Volex Forge builds the finned body and returns a manufacturable STEP or STL for machining or 3D printing.

No repetitive fin sketching, no CAD seat. The fin array is generated evenly across the base and checked before download, so the geometry is clean and printable or millable.

Frequently asked

Can I set fin count or pitch?
Either — give the number of fins or the gap between them and Forge spaces them evenly across the base.
Is it suitable for 3D printing?
Yes. Fin thickness and spacing are yours to set, so you can keep the geometry within your printer's or mill's capability.
What does a heat sink cost?
Forge is free to try; individual parts are from £2.99. You only pay when you download a file you want.
Which format should I use?
STEP for CAD and CNC, STL for 3D printing. The fin array is 3D, so DXF is not used here.
