Caproni Ca.40

[comPVter]

After a couple of balloons, now it's time to try something heavier than air.

So I take my copy of "Flight of the Giants" looking for something big.
My first attempt with a small airplane doesn't satisfy me too much.
My Ansaldo A1 is too thin and fragile (link).

Caproni Ca.40 appears a good choice: it's big enough, ...and Italian

So I started from here:



I opened the image with the great free software Inkscape and I vectorize the bitmap with only few click.
Than I imported in Rhino and rescale. After a bit patience...



It's time to prepare for the print in two version: assembled and disassembled.



I'm testing the first way. If it will be ok I think that could be better and easier to print:



Now it's working. I keep you tuned.

utterly gobsmacked, I can't wait to see pics of the finished beast!

Impressive Dino.

Noooo ! I crashed the Caproni Ca.40 removing the supports !!!

One more time, it is a bit too delicate, but before start to redraw it, I'd like to test a "separate print" (the disassembled version).
I promise: if it is just printable I'll share the file with all the community.

At the beginning, I was really next to put all in trash, but I know, I need a lot of exercise with the paintbrush.
So ....





Here's a comparison with the little brother Ca.3.
You have to use a lot of fantasy to immagine a good model
...the propellers are still missing....





Please, be patient..... The next one could only be better !

Never let a bad model or unused bits go into the trash. You never know what you might do with them.

Nice "recovery" with the bad one! That will be much fun to swap in when the good Ca.40 goes down.

As a Shapeways modeler, I'm curious: what are the minimum wall thicknesses and wire thicknesses (like a strut) with that printer? How hard is it to remove the supporting material?

(Shapeways has a black acrylate material that looks similar, but I'd never trust an untrained person to tell a support-structure from a wing strut that is supposed to be there.)

[comPVter]

My printer is a really cheap one. Less than 500 €.
I use also cheap material (PLA) for the first tests: 48€ in a big roll of 2.3kg.

For these reasons I print wings no thinner than 1 mm in the middle. But the theorically step in Z is 0.1 mm,
so the wing-profile is really thin !

Concerning the vertical structures I tryed 0.75 mm, but is not a good idea.
At every layer the printer have to be really precise in movement to put another 0,1 mm on every columns,
So I have two different way:
1. print the structures separated, in horizontal. But I have to mark the position on the wings to facilitate the assembly operation.
2. redraw biggest supports (1 mm could be ok). I have to double check the size of the Caproni Ca.3 ones.

Concerning the support, I use Simplify 3D a really good software, in my opinion, because have a incredibly fine tuning parameters:
- Support infill percentage is reduced at 20%.
- The extra inflation distance is 0,30 mm.
- I combine supports every two layers only.

I print the airplanes slowly : 45mm/s raising a bit the temperature respect the suggested (210 °C instead of 200 °C).

I'd like to keep the models light, so the infill is 10% only, with grid rectilinear and 25% outiline overlap.
For this reason I raise the top and bottom solid layers at level 6. The outline/perimeter shell is 3.
To keep the surfaces smooth I prefer a inside-out direction.

I hope that my experience with all this boring settings could be useful !
All are empirical, so I'm open to suggestion to improve them.

Nice project.

Delicate thing this 3D printing.

[comPVter]

Update: I'm next to the goal.
Stay tuned !

[comPVter]

That is strange !
After few weeks, I noticed that my post last was lost....

Here's some photo....



I hope you like it.



The most difficoult parts are the rudders and the propellers.



It is not difficoult to glue. I print a tool to allign the wings separators:



Next step: the crew !



I keep my first attempt for scenario...



Enjoy !

[Ken at Sunrise]

Enjoy !

I love the comparison. Great for scenarios.

Sometimes our first mistake leaves us with something awesome!

[Marechallannes]

Could be a "crash landed" sceanrio, too.

[Kubajs]

Great job.
Looks fantastic!

[zenlizard]

Somehow missed this back in October; glad I looked now.

Bang-up job on the second go-around. That's exactly why we make mistakes the first time around.

Very impressive. I couldn't even begin to think about such a project, let alone complete it. Congratulations Dino

Ciao !

Have a look at this masterpiece:



I found the picture here: http://yuripasholok.livejournal.com/5790900.html
It's the Caproni Ca.43 in hydro version with torpedo.

I really love it !

It could be my next work :-D

[flash]

That's a work of art - What a remarkable beast !

That. Is. Incredible. Thanks for the link. Amazing work!

[zenlizard]

That is nothing short of amazing.
