Mass production of more than one nosecone at a time will save on time and hence production cost. I have been printing 9 to 25 BT-20 sized ABS nosecones in a single batch.

Can a large 3-D printed nose cone ( BT-70 and larger ) be thin-walled, hollow, durable, lightweight, and shock resistant ?

What would the cost be to do a 5:1 BT-80 Ogive with .060"- .125" wall thickness ?

How much would it weigh and how long would it take to print ?
