advantageous on the smaller scale when only one or two pieces are required. Case studies can already be found of private owners experimenting with additive manu- facturing on their personal aircraft. In one example, an owner enlisted the help of an addi- tive company to re-engineer, print and replace the exhaust stack for his P-51 Mustang. The 3D part is stronger, more durable and reduced the part from four pieces to one. While recent progress and momentum is evident, the question remains to what extent will additive technology be accepted and im- plemented in the highly conservative, safety- driven aviation industry?
