Legendary Blackbird - Part 0: Genesis... (3D Printing)


Recommended Posts

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:

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

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...

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

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 ?

 

Regards

Robert

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 🥴
