3D printed in NYLON using SLS for the truck in this video: https://youtu.be/tPoyGHQQrmI
Printing in Resin (With SLA/DLP/etc.) Should also be possible, but I haven't tried it. Printing with FDM will be challenging, particularly on the auger/screws.
If you want to print in SLS I advise using a 3D printing provider.
PA12 Nylon Nylon Powder
This is Nylon Powder, as was made using SLS, which is a powder-based process.
Created in SolidWorks. It had a little freak out so it had to be saved with a few separate bodies (called Shells in magics). I then used Materialise Magics to Unify (called Combine in SolidWorks) the shells.
