Alumide is a composite material that combines aluminum powder with polyamide (PA12) powder. This blend combines properties of aluminum with the flexibility and durability of nylon. Alumide is used in selective laser sintering (SLS) processes.
Alumide looks a bit like casted aluminum due to its grainy metallic texture.
It is able to witstand temperatures up to 140 Celcius, making it one of the more heat-resistant plastics and usable
However, it’s worth noting that alumide does not possess the same mechanical properties as pure aluminum due to its composite nature, but it still offers a compelling balance of strength and versatility.
