Absolutely stunning work Serkan!

Thanks mate! I am impatient to see  the print results...

Can all these parts be used with Italeri kit?

[Serkan Sen]

To be honest I don't know yet. My 3D model especially the fuselage is based on overlapped circular sections and I haven't compared the dimensions with Italeri kit. I will do this check when the parts are ready...

[Hornet]

Maybe you can check the nozzle and inlet parts if they fit the Italeri kit. 🤔

[Serkan Sen]

not a bad idea. I will do this check soon.

The print has been completed. Here are the fresh parts:

 

More pictures will be available soon . But first the parts has to be washed with IPA and cured under UV light...

All parts were cleaned and fully cured:

 

 

The printed parts weigh only 43gr in total including base&supports.

 

There are some areas to be improved but I am really happy what I got even after first print.

Amazing...

[Serkan Sen]

Here are the parts to build three versions:

 

I have generated the support structure both in CAD model and chitubox tool to see which one is more effective:

 

I didn't notice any advantage one to another for printing these parts. What I would conclude that if the support structure is parallel to z axis then chitubox is very quick and efficient. Otherwise adding the support structure in CAD model is more convenient.

Some issues to be improved:

 

The scaled pitot tube was too thin to print. The diameter should be resized to print it reasonably.

 

Also the chine edges are too sharp to print. I will round the edges with a diameter of 0.2mm:

 

Here are the all parts printed till now:

Super!!!

[Serkan Sen]

Thanks Bill,

Tomorrow I will make some fit tests with Italeri kit.

Is this a commercial endeavor? I'm sure I'm not the only one who would like to acquire copies of these exquisite items!

Ditto. I have an A-12 and interceptor version on my wish list.

+1 for the A12 parts. I'm interested in the hardness of the cured resin, would it be able to scribe panel lines into?

Fascinating stuff and the end result looks great too.

At the beginning was not. But now I see that there is a potential of selling the parts to finance my other fancy future projects (like RF-8 Crusader, TF-102 etc...) 😁

 

But I will first complete Blackbird family by adding YF-12 and SR-71 variants including different nose options...

As I promised (remember my A-12 Oxcart build) you and Nikolay will get a complete set when all parts are completed.

Thanks Iain. I hope the completed model will look good too.

Thanks Neil. I will post some images about the scribed and modelled panel lines soon. (I have to prepare them first 😁)

Hi Serkan, would like to see how the seats print out. Have you plans for the undercarriage bays or will you use what you have done before with the kit parts ?

Hi Robert,

Based on my experience (which I gained during last few days) I need to thicken many areas of ejection seat. That means it won't be fully scaled but in any case better than the kit seat. Also I will print a pair with more realistic part thicknesses for my Testors 1:48 Blackbird.

Regarding to landing gear bays and assemblies I haven't done anything yet. Maybe I can start with doors but the rest will be done next year (oops next week will be already next year 🙂 )

To remove the support structure and base plate I use two types of razor saw instead of flush side cutter which easily leads to break resin at undesired location (as the resin is very brittle)

 

For support structure I used Hasegawa Modeling Scriber Scribe Saw which is extremely thin (0.1mm I assume):

 

For base plate I use Xacto Precision Razor Saw with 0.5mm thickness:

 

Here all parts were processed and assembled together:

 

As you may have noticed the A-12B Mother Goose's aft wind shield is missing because somehow I lost this tiny piece 🥴

Here are some pictures to compare printed parts with my ongoing (and never ending 🙂 ) Oxcart:

 

Note that how perfectly fits the canopy parts to their frames:
