I'm not shortsighted at all. You originally asked about getting one NOW and what use they could be in this hobby. You also asked about high volume production which is a complete impossibility right now. I'm sorry you don't like the answer.

I would challenge you to go get one TODAY and then show us how wrong I am. What is coming is one thing. What IS is entirely another matter. RIGHT NOW, they really don't have a practical use for r/c helicopters for structural components.

just wanted views on the ones people owed
I didn't start this post to have members agruing between them selfs. I just wanted to know if it was a good investment to do scale parts with. And maybe come up with ideas to improve my own heli's and help out friends. I really would like to have one and plus get a smithy cnc. But thats out of the question. See guys I'm a dreamer and have a lot of ideas in my head. Sometimes I wish I could do things to make myself feel better about my injuries that I've been suffering with for four year. No I don't want people feeling sorry for me. I just want to be able to get them out of my head and into something I can wrap my hands around.

So with all that being said let turn this thread into a good read and move on with this great hobby we all have and keep making it better and fun. To past down to our younger pilots.

Jeffrey:) (Love and Peace to all)

I use RP shops a lot and unless you plan on going into business making RP parts, shop it out. The machines change enough over the years that you will be stuck with a low resolution machine if you are trying to do it on a budget. Same goes with 3D scanners. They change so much it isn't feasible to purchase one unless that is your business.

Prototypes have evolved a lot in the last ten years. The last assemblies I did were full functional prototypes for a large consumer electronics company. I had crystal clear buttons, LCD screens and tuned micro speaker housing. Next to the competition, you couldn't tell that it was a prototype other than it didn't have knit lines like the injection molded parts did.

As for strength and real world application... yes, production parts are made on these machines. The main shop I use makes MANY parts for the Boeing 787, FA-18 Hornet and the Osprey. They are all FAA certified and going into production aircraft. The blends they have today are light years ahead of anything that was available even three years ago. There is even a special carbon composite material I was able to see that is simply amazing. Not cheap, but VERY functional in high performance applications!

As for it not being able to replace CNC metal... these are parts that simply cannot be machined nor molded due to complex geometry. The ONLY way to make these as single parts is to build them in the RP machines. One of the 787 components for example replaced 17 separate injection molded parts with a single RP part. Amazing!
