3D Printing

[Crispy1688]

Hey guys,

I'm looking into the feasibility of getting an upper receiver 3D printed but I don’t know enough to make sensible decisions so am appealing to the hive mind. 
 

Has anyone got experience of SLS printing in PL-12 or other nylons? How do you rate their resilience. 
 

Does anyone know of a company that will print airsoft bits using these or equivalent materials?

cheers!

I've seen a few fixed carry handle uppers for TM MWS printed in PA12 by Airtac.  They look pretty decent.
