If you follow us on Twitter, you may have seen that we have updated our print farm. We have 4 Markforged printers set up, 3 of them are Onyx Series while our first one was a Mark Two. We've been using their Onyx filament along with embedded carbon fiber in the Mark Two. Onyx is a filament created by Markforged that consists of chopped carbon fiber. This allows us to print stronger parts that have a higher melting temperature than PLA. PLA is a good material, but we can't leave a Dexter made of one in a car during the summer here in Las Vegas. We have before and it needed major repairs due to deformation.
