Summary

I love this model, it's nicely detailed and very well made.

The original illustration by Splotchyink has a great blue dragon with a pink tummy,I wanted to re-create that in print, so he is sliced and printed then re-assembled.

He is printed with Faberdashery PLA - Electric Blue and
CHERRY BLOSSOM PINK.

Instructions

print each section and assemble.

This was also a test of hollow printing, one side was printed hollow (0% infill) and the other side was 5% Tummy was printed with 10% infill

He is 2 x the original size to show off all that great detail, you may want to scale him back down if you have a smaller print area.

You don't need to use any support to print this model. :)

Little question, how do you put it on skeinforge where it doesn't intersperse the entire model with fifty solid layers? Because it seems that skeinforge likes doing that to me. with models of this particular type.

With organic objects you need to uncheck 'infill in direction of bridge' in Skeinforge this will stop it trying to 'support' over and under-hangs by adding the partial solid layers you can see.

You will also need to play with the number of shells when you remove the infill direction.

This was a top tip by Sublime - it's explained here in one of my earlier blog posts, take a look at the bottom section of the post - Pink panther woman - http://richrap.blogspot.com/2011/06/hollow-printing.htmlhttp://richrap.blogspot.com/20...

Thanks man, I'll defenantly give that a good read.

Hmm... I have an idea... this just may work for my needs... Muhahaha

Bratty Dragon + Sim City 2000 set = Awesome Godzilla like playset

Now I need something to resemble King Kong :P

Really nice! :)

It would be EVEN NICER if you added registration holes like I did for the tie interceptor, makes it much easier to glue together exactly.

That is a good idea! thanks Bob.

He is held together with double sided tape at the moment, I'm still experimenting with fixing PLA together.

What glue do you use?, I have tried all sorts and usually end up bonding together with heat.

I have used both super glue and UHU 300 plus with success.

This is astonishingly good, not to mention not having to worry about those time consuming support structures. Not to mention he's almost life sized (yes, he's a very puny little dragon, there's a lot for him to be grumpy about.)

Your model is very well detailed, I bet even if you printed him at 4X size you would still not see all the detail, but something to aim for with a smaller nozzle and finer layer slices. :)

Thanks, really, your maing me blush.

I doubt you would 'need' to see all that little detail, because what you have right here is detailed enough because all that extra 'detail' is in flact tiny flaws in the sculpture :p . Though, that doesn't mean I'm not gonna be trying to make better models in the future, maybe a few more of Roal.

Very nice, I was wondering if there was a way to slice him so the wings could be printed sans-support. Great job. I like the belly slice as well. More color for Roal.

Thanks, I'm sure there is more you could do with him, maybe we can encourage SplotchyInk to model him in a few more positions :)

I would like to have that cookie he is holding coloured and the eyes, spikes etc.

Of course I will sculpt him in different positions, but only if you reveal your secrets of model slicing. (And even if you dont, I'll probably do it anyway)

I just used Netfabb to slice him up, that's the easiest way when you only have an .STL file

With a real source file you can do it in most 3D programs.

What was he originally modelled in? 3DS Max?

I used Sculptris to make him, and then conveted him from .obj to .stl with Blender.
