Powder
#1
Anyone know where one can buy the powder to start doing some tests with a ~100W blue diode array? Possibly like something used by Metal Matters in the video...

Hi Martin,

I source my powder from metalpowders.com.au but you can get it from Aliexpress as well. e.g. https://www.aliexpress.com/item/32966310...web201603_

I'd enquire about what the mesh sizing is before buying anything first. I currently use 40um but will be changing to 80-100um for safety reasons.

So the mesh sizing is the size of the metal powder beads? Also, what were your safety concerns for needing to go up in size?
Thanks!

At levels as fine as 40um it is possible for the powder to be absorbed through the skin. The fine dust can also become airborne and enter the body that way. In the case of Aluminium, fine dust can be explosive.
