A bit faked from GE but nonetheless here goes a glimpse of the upcoming new 3D Printing technology and what it can do -the later being very real. Those are the adaptive machines (similar) that HQ have put on order last October, we expect receiving those in July 2016. If all goes well, we'll have Aftermarket Jet Engines as a replacement for depo taillights.
Well, maybe it is not all that faked, who knows. Wonder how they printed the air-bearing (33k RPM lol) and fuel injector, etc etc. Regardless, still a good start/demo and worth showing in its current form.
Welcome to the future! and p.s. no it is not going to be plastic printers as many believed :/ give those another 5 years and they are all dead - you'll have laser and metal dust instead
