Default Cockpit draft

I've been experimenting with finer 3D prints - one is a rough draft at 0.15mm pitch with a lick of a paint and no sanding.

The other is at a higher resolution (0.1mm) and density. Took 10 hours to print!

Default Engines!

Thought I'd keep you updated with some more prints - bells and whistles!

Spine is also complete - just waiting for it to cement properly.

The last landing pod is also being printed, so I'll get an overall pic of the Eagle by Wednesday?? ... we'll see

Default Engine!

... here's a sneak peak of the engine that's going into the Eagle ... chaser lights 'n' all!

3x CR2032's will fit in the back part of the engine and there will be a button to change the chaser sequence.

Printing the back walkway tonight.

Default Engine installed

... back walkway is now done and I've installed the engine ...

Most things are snap-fit, so you can slide the back walkway out, take off the top cover, remove the engine etc..

(I hope I haven't chased everyone away - even BlueMoon hasn't been in touch!?) ... oh well

Nice! I'm sure they're watching. Very interesting job here!

Looking good. Your progress is excellent, there are lots of lurkers for sure - lots of different topics covered here to keep us interested.
Something else to touch on - what design software are you using?

... Aww - now I feel bad

Anyways, I'm motoring on determined to get the whole thing finished. I've got two 3D printers chuntering away and a box full of bits that need slight mods each time until it's good enough.

I'm using 3DS Max 7 (a bit old) but it does the job - exported to Netfabb, Simplify3D and finally the printers. The plans are mainly based between Roberto's and Daniel's although, if needs be, I can be explicit to either one.

As for the price, I will give it once I've got a good kit ready to go.

BlueMoon - I'll get the rest of the proto-kit to you soon - I don't want to send bits that you work on only to find that I've upgraded them and wasted your time!!

Meanwhile, here's a couple of pics of the overall 37" design.

Thanks again for the vote of confidence guys

Edit: Just as a side note, how much interest would there be for a 3D printed 44" Eagle to Daniel Prud-homme's plans (or Roberto's for that matter)?

You mean 44?

I know there's rumour Round2 is coming out with one...(not sure when) but in the end an accurate one, no matter where it comes from if the price is reasonable will sell.
(I think)
Yes, it's true about the spine - I'm having to print a solid spine for the current 37" as the semi-hollow spine bends a bit and will probably break if held from one end! To help overcome the bending, I'm trying to make the parts as lightweight as possible without compromising strength.

How about producing 22/23/33/44" parts like the beak/engines/cages/landing pods/walkways etc.. ? Perhaps the spine could be partially 3D printed with brass rods for strength??

Also what sort of price do you think is 'reasonable' - it has cost me quite a bit to produce this model but I do want to make it affordable (more so than some of the prices I've seen!)

I'm just printing a 44" beak (as a trial) by knocking the nose off - I'll let you know.

As an indicator, you should sell at the going rate or a little less. Considering, there's a lot of ppl now with 3D printers doing the same thing you are which you can find at:
http://www.shapeways.com/search?q=space+1999

A 3D printed 44 Eagle was made, I believe in 2008 which from it made the master and the cast of many parts sold on this site. Anyone, can now take your part(s), toss them in silicone and cast a resin kit from it. Easy-Peasy....(simple).

As for 3D printing, once a good file is done, it's done and once it hits the public market (yours or someone else's) then it really has no value. It'll be just a matter of time.
And resizing a file/editing a file to one's preference, is simple. Very much like computer scripts/programs/code are done today. You don't need to be a programmer to copy/paste.

Personally, I wouldn't pay more than what WARP currently sell their kit especially when Round2 may be coming out with a 22/23 inch. This will be priced for the consumer market and mass produced and I don't expect it will be more than a few hundred.

The only reason PE's are selling a little higher is due to Ebay high pricing and because PE's are no longer produced.

I don't think a 44 could be (completely) made as the Spine and Landing Gear would need to be constructed from a stronger material.

IMHO, I don't think what is produced from 3D will make the money but the original source file(s) and only for a short time as more and more of it becomes main stream
and everyone has a 3D printer sitting beside their microwave.

I'm sure you're right - certainly 3D printers will become commonplace with lots of colours and producing smooth, high-quality models. But for now, there is room to produce a few kits.

I suppose my main objective for this Eagle is to make something inspiring - detailing both inside and out with working parts. The Eagle is probably one of the most exciting and technologically 'believable' models out there and it deserves to be modeled in Hi-Def ... 3D printing it will share the 'joy'

Thank you Richard for your advice - do you have the link for the 22/23" Round2 model? I couldn't find any info on this.

I am not too familiar with 3d printed parts, but today came across this video in which the guy uses "acetone vapour bath smoothing" to remove some of the lines caused by the 3D printing. Seems to work quite nicely and would reduce sanding considerably.

From the look of the pictures does the Printer leave a Slight print out pattern on the surface and need sanding?!

The parts are not going to be acceptable straight off the printer and the acetone vapor bath is almost certainly going to soften details that need to remain sharp. Unfortunately, careful sanding is really your only option on such highly detailed parts.

XTC 3D might do the trick ... I've got it but haven't had a chance to try it yet! I'll post the results next week. Meanwhile, there is a fair bit of work needed to sand / dremel if you want a smooth surface. Acetone smoothing is good for organic shapes but not too good if you want to retain sharp corners. At least with XTC you can apply it just to the areas that need smoothing (in theory at least)

It's all a bit of a balancing act I think...acetone vapour maybe an hour at a time and inspect the parts ? You are correct we want the smoothness without losing the detail, which is why I suggest an hour, two at most, and examine the results. It's all very new this tech but we CAN get a handle on it. I reckon there is an "inbetween" stage we need to find between the vapour bath and the sanding. All of us are used to sanding anyway but the more we can reduce it the better. Different plastics of course will require longer or shorter times in the vapour bath. We are really just at the experimental stages here. A whole new world opens up.

As you say, it seems like you ought to be able to get decent results with this method but it's going to require close monitoring of the process and taking studious notes. Should be interesting to see how it all goes with actual Eagle parts.

I am far from an expert B.P., but yes worth a challenge for someone.

Default XTC-3D tryout

I finally managed to mix some XTC-3D and apply a coat!

Here are some preliminary shots of the beak and tanks with XTC-3D applied.

I realised that I probably haven't applied enough as thicker layers of XTC do hide the striations completely. I'll rub down and try another coat.

Here are my initial results ...
