Hello 3D Printing

I am trying to find some information about the possibility of printing vintage motorcycle engine.
How advanced is the metal printing technology, I can read some info about jet engine printing and gun printing but can't really find anything about piston gas engines. Any suggestions would be helpful.

Yup. You should either cast it, or use a subtractive form of manufacturing from a block of metal. Like cnc.

It is average build quality. Not the best. The locking mechanism for the visior is just plastic, actually part of the visior is just spring-loaded against a plastic pin. Chicago has no helmet law but after a 5 K miles road-trip it's already broken.
The wind and rain protection is average and you can only have it up or down above parking speeds.
Check their Diesel line i hear it's better...

Typical late night cabbie dining place where you can hear Arabic language more often than English and TV is on a Jazeera but the food is good, plentiful and delicious. Not the cleanest bathrooms.
