Does anyone know of or has anyone tried using a 3D Printer to make test parts for one of their RC Heli Models?

I don't think they are ready for primetime just yet.

Hmmm, I think your uninformed on this one TMoore.

If we can get one of the CAD engineers to chime in I'm assure you that this topic will get interesting.

An "upgrade" from what, modeling clay?

Nas,
Ya think? You can make a lot of things with them, it just depends on how usable you need them to be.

Selective Laser Sintering (SLS ) produces metal parts that include materials such as titanium. These produce parts similar to cast parts. Just as cast parts require finish machining, SLS parts do too. It uses high powered CO2 laser and the machine price is out of reach for most.

Filament Doposit Machining (FDM) can use strong plastic such as PolyCarbonate and achieve 70% molded counterpart in mechanical strength.
But, this is one of the slowest process as you deal with building and melting through a single nozzle. As you get more accurate, build time increases and machine cost goes up. Pro grade FDM plastic material can cost as much as $200/lb while molded counterpart can be as low as $0.30/lb

I have actually used low volume electronics housing out of PC FDM for production use.

There are other methods such as ProJet, SLA but above two will produce parts that can be used in our helis if the cost is no object as simple fan housing will cost as much as whole heli and still not as good as molded parts.

Read Peters post on this thread. It's old news.

The machine tool biz has been using these things for years so I'm not unfamiliar with them. They have their place for a lot of development things just not heli parts unless you have a very expensive system and a lot of time.

Let me put it to you this way. NASA has been contemplating putting a 5 axis machine tool on the space station but not a 3d printer. Why is that?

Just a hunch, but I'm guessing the 3D printer needs gravity to work.

Most do, but FDM does not as it lays very thin molten plastic right next to the already hardened surface and re-solidify.

Yes 3D printers can make production parts...No its not practical, unless your a defense contractor and the taxpayer is picking up the bill.

Seriously...the only folks making production parts are those in the aerospace industry who have found that 3D printing is cost effective with very complex designs.

no kidding...whats the point of getting all super complex...with todays FBL DFC heads, direct to swash, one piece side frames, low part counts...i don't see any advantage to it.

even a good machinist on a manual mill/lathe can turn out a typical heli part in a mere fraction of the cost...maybe even faster too.

showing a preference will only get you into trouble, 90% of everything is crap...

They're coming but are not there yet for structural parts for our helis. I have purchased stock in one of the 3D printer manufacturers because I do think they are going to be a big deal in the future.

We use these processes at work to model headlamp components but they are in no way structual enuf for our needs.
