So this technology, 3D printing, and new design rules really help us to reduce the weight, which is the biggest issue in aircraft design, because it's directly linked to greenhouse gas emissions.
Ova tehnologija, 3D printanje, i nova pravila dizajna zaista nam pomažu smanjiti težinu, koja je najveći problem  kod dizajna letjelice, jer je direktno povezana s emisijom stakleničkih plinova.
