Hello All,

Today an English friend of mine sent me the following:

"Now lowering the bar to sub-£700 (about $1000?): the Velleman K8200 [http://www.k8200.eu/locale/ ]. It claims to be able to print anything that fits in a 20 cm cube (8”), to a half-millimetre resolution. The demo video [here: http://www.youtube.com/watch?v=MNEZLUXctf8 ] is most impressive. I’m planning to let the technology “firm up” a little for a couple of years, but this is easily affordable!". Also:

Here are links to more information on the Velleman K8200 (see: http://www.google.com/search?sclien...K=Google+Search. Not only could fins and nose cones be 3-D printed, but with the appropriate attachments and holders, such devices could also precision-sand balsa fins to tapered, aerodynamically-contoured (with precise airfoil sections) shapes. This would be a boon to competition flyers and scale model rocket enthusiasts.

Hello Blackshire,
Peruse my shop to see what the current state of use of 3D printing for rocketry parts. What you will find publicly is only about a third of my inventory to date. PM me on that site or this one for anything you don't see, I might have already modeled it. And yes, competition style designs are made ( not public for obvious reasons), as well as scale.This goes for everyone; Your welcome to try any of my designs as test proofs. A lot of them have not been tested (as there are so many). So if you are willing to participate, give it a go. Already folks are pleased with some of the printed results.
Go to link below or search Cespedesign Multimedia:

I hope you all like what you see and approve.
Kevin A. Cespedes

I went. I saw. I...gawked! THANK YOU for posting this for us! My mind is alight with ideas; one (which I've longed to see realized for years) is that it is now possible to make high-fidelity scale sounding rocket parts (fins, fin cans, boat-tails, payload sections, antennas, nose cones, etc.) that will enable whole series of multi-stage scale model sounding rockets to be built (Nike-boosted ones, Terrier-boosted ones, etc.). It will even be possible to make all-plastic models, which will enable any useful scale factor to be used. Also, I'm pleased to see your plastic versions of classic Estes balsa nose cones. What is the smallest size that you can 3-D print nose cones, nozzles, and fin units?

Not to mention small AV-bays

Hmmm...a Cineroc could be printed so that its (modified) interior fittings would accommodate existing small video cameras!

Thnanks!
All of the aforementioned ideas are in the works. You should check out the shapeways shop to see what people are doing in the DIY section. As for the smallest size those details vary from material to material but for our purposes less than a quarter centimeter square roughly if my memory serves me correct. Fitting screws and bolts, launch rails hardware custom payload sections can all be custom designed. It just takes skill that I am developing. I plan to do a writing on all my research for NAR soon. Camera housing shrouds are easy once you specify the hardware.
EDIT: If anyone is purchasing a print of one of my designs PM me.I would like to get some pics of the printed product for the shop so that rocketeers can see the real results, I hope to replace a lot of renderings with the real thing!

That will be a much-anticipated NAR R & D report! Hmmm...the ability to print 2.5 mm size parts should even permit detail parts like 1:100 scale Apollo CSM thruster quads to be printed.
