I wouldn't be at all surprised if one day soon we get top end cameras made with 3D printed titanium bodies. -- Regards, Eric Stevens |

Its combustion chamber, injectors, pumps, and main propellant valves are all 3D-printed." https://www.ge.com/reports/treat-avg...rcraft-engine/ "More than a third of the components in GE’s advanced turboprop (ATP) engine, rated at 1,300 shaft horsepower, will be built through additive manufacturing methods, a catchall term that includes 3D printing." https://www.designboom.com/readers/u...ne-12-20-2017/ -- Regards, Eric Stevens |
