Hehe - another mega-brilliant build to follow and drool over :)

Great subject choice as always :thumbsup:

Wow, looking forward to seeing this one through! I think we'll see a lot more of this kind of modeling as people become more familiar w/3D design and rapid prototyping becomes more affordable, hopefully to a point where we can afford a setup right on our workbench.

Nice work Stratos75. I've done some amateur 2D flat pattern work designing balsa RC planes on TurboCad v12 that I purchased for about $20 at Amazon. Once complete I emailed the files to a business equipped with a laser cutter who charged my credit card and shipped me the laser cut balsa and plywood.

Doing a quick google for rapid prototyping services I found several that will create a 3D object from customer supplied STL files. So it looks like this is financially within reach to most any hobbiest right now! But wait, how are your 3D CAD skills? I think that's the limiting factor here. I know how long it took me to learn TurboCad 2D in my spare time. I shudder to imagine the steep learning curve required to make that Dino file. The creator probably does this kinda work professionally.

Amazing. I don't really see what's wrong with the red one to be honest, but the new one sure looks good too. What an incredible way to make a model!

Thanks, friends!
...I don't really see what's wrong with the red one to be honest...
It's 7 mm longer, 5 mm wider, 2 mm higher and has some distortions in a shape. Also the Airfix model has 15" wheels instead 13". So I'll mill new wheels too. The engine I'll copy from Fujimi's Ferrari Dino 246 GT.

:eek2:Excellent start to this brave project!
Kudos to your brother for his 3D design skills! :thumbsup:

I'm looking forward to see this project develop, it sure will be excellent to watch.

If I may ask, where do you get the blueprints for your projects?
Thanks!
There are no any blueprints, but only fotos. We use a Photomodeler program to find base points. Then they convert to Catia, where we build curves and surfaces, then control points convert back to Photomodeler, compare with photos, correct in Catia, compare with photos again and ets.
Now I want to show some problems of a body surface what has made by SLS method in other light. It needs in filling.

The rough surface is normal for a machined part. It would be impossible to make a perfect one because the tool's cutting edge should be very very small and also it should move with impossible to achieve small steps.

Did you try 3D printing? It is expensive but it also gives better finish.

Wouldn't it be easier to just sand it instead of filling it?

That surface reminds me of the some of the white metal castings in Hiro kits. Maybe they're using a similar process.

Is the matrial milled from a chunk with a tool or is it a liquid cured in tiny amounts as the surface is created?

You do know that some of us actually build the kits, right? :lol2:
Seriously though, this is some great work to watch. Keep it up!

I am actually building the Airfix model and I'll be following this thread closely... :smile:

Thanks for showing the comparison pics. Very interesting!!! It all depends on how good your references are though right - and how accurately you can model them. Your process does sound very accurate though. Again, thanks, and great stuff.

I can to mill all parts free of charge because I've got CNC milling machine on my job and it gives me more smooth surface. But I've used SLS method for build time reduction, although it costed to me of some money. This method is relatively low cost. More about it read for example there http://www.brightopinc.com/Prototyping.htm The same work on SLA method would cost to me about 150-200$:crying:

Thanks for the link.
Now I see why you got the rough surface on the prototype.
There is a need for puttying it but it will be fairly easy and fast to do, and you sure won't have difficulties doing it.

Also thanks for the info on the 3D modeling process, I'll take a look at that Photomodeler software as I'm planing to to a few not existing models in the future.

Today I've started a work on a surface correction.

Looking good.

Is it worth to you to continue doing this if the Fujimi is a good kit? I understand that it gives you satisfaction but it does take a lot of time.

Will see. I don't want to leave this invention and don't hurry up to finish it.

Why are you sad?!
You should be glad that you can do a better job than the Fujimi guys. :)

I'm happy too, as I bought the Fujimi kit and will have plenty of work to do to make it look OK! :D

alot of work for minimal imperfections imo but should look cool when finished.
I like the fact that your designing it and producing the model yourself..good luck
