If anyone in the USA is not going to ever use their 3D print head send me a PM and we can discuss the possibility of me purchasing it from you, I would like to have a spare to put a ruby nozzle in so I can print more abrasive material.
I’d wait until after all backers are filled. Chances are good they will be purchasable after at some point…
yeah I figured that but if there is an individual thats not going to use theirs I’d rather not wait. I have never used the cnc or laser on my SM1 hahaha. Offer is still out there if anyone has a print head they aren’t going to use doesn’t really have to be in USA but just easier!
Yes the spare parts will be available in the future. 
Don’t have a defenite date though.
