Metal AM dense vertical-fin heat sink
Dense vertical-fin metal heat sink on a solid base — for discussing printable fin pitch, powder escape between fins, and which base faces must be milled flat for thermal contact.
Typical specification
| Item | Typical value |
|---|---|
| Process | Metal powder-bed fusion |
| Material | Aluminum or copper alloy |
| Form | Dense vertical-fin heat sink on base |
| Thermal | Tall fin array |
| Post | Powder flush between fins; mill base |
Fin-array mindset
Dense vertical fins look simple from above but need clear minimum pitch, powder-clear paths, and a plan for milling the thermal-contact face.
- State which fins are flow-critical versus cosmetic
- Keep the base solid enough for fasteners or TIM
- Do not invent thermal-resistance numbers on this page
RFQ checklist
Alloy family, envelope, target fin pitch class, flatness of the working face, and any cleanliness requirements you need stated.
