Having put this amount of work in I'd expect @Serkan Sen to keep them firmly private and sell either the files with a strict license or just to sell the printed model or parts. I used to post stuff to Instructables but other than competition prizes (which are largely just branded tat) it was just competing with my own sales 2 Link to comment Share on other sites More sharing options...

It is too early to say anything about availability of the parts or the files but definitely I will not put them into public area. In case of selling the parts or files the money will directly go to charity/foundation account as a donation. Serkan 6 Link to comment Share on other sites More sharing options...

You’re moving fast, Serkan! I’m sure it’s a very fascinating process and you’re always have a chance to perform a step back if something goes wrong. Unfortunately, the «Save As...» feature isn’t available in a real modelling.

Serkan Sen Posted January 2, 2020 Author Share Posted January 2, 2020 21 minutes ago, Nikolay Polyakov said: The same seat as for the Starfighters? From "EjectionSite.com" "This is a Lockheed Design which is not much different from the Stanley designed Lockheed C-2 (later modifed into the S/R-2) seat which preceded it in other aircraft [Note: the C-2 seat was used in the very early A-12 and SR-71 Blackbirds as can be seen in the cockpit of A-12 06925]. Some of the differences between the C-2 and the SR-1 seat include the omission of the leg guards and arm restraint nets which were used on the C-2. Due to a fatality which occurred early in the SR-71 program where a crewman was killed when his helmet impacted the headrest of the seat during a structural breakup, some of the C-2 seats were equipped with a headrest extender to more closely fit the seat to the crewman." 2 1 Link to comment Share on other sites More sharing options...

Serkan: loving the attention to detail here but I really would advise test-printing a diagnostic part sooner rather than later in order to get a feel for the tolerances of the resin output - just to reassure yourself that the level of detail being incorporated will actually be reproduced in the way that you anticipate. Also critical in order to work out what orientation to print various parts in, regarding the necessary support structures and resultant contact artefacts on various surfaces of the airframe that would need cleaning up afterwards. I've done a couple of test shots with the Elegoo and they are already influencing some of the design decisions I'm taking on the wing I'm building. 6 1 Link to comment Share on other sites More sharing options...
hendie Posted January 4, 2020 Share Posted January 4, 2020 I completely agree with Tony's suggestion Serkan. You have incorporated a lot of really interesting detail, but at 1/72 scale and the resolution of the printer, a lot of that detail is going to get lost in the noise. You need to experiment with printing to see what the finest detail you can actually print is going to be. 2 1 Link to comment Share on other sites More sharing options...

I will make some test prints using ejection seat model which is enough detailed to see output quality. The support structures will be added by checking the isolated islands before sending the jobs to printer. 1 hour ago, hendie said: You have incorporated a lot of really interesting detail, but at 1/72 scale and the resolution of the printer, a lot of that detail is going to get lost in the noise.

Maybe I should print in 1:48 even in 1:32 scale to overcome this issue 🙂 Currently I have no idea how to add and print panel lines to surface.

Depends how crazy you want to go. I did an experiment making each shape as two nested bodies one slightly smaller inside the other. then drawing panel lines as a sketch and using those to remove some of the outer body. It works ok(ish) but there must be a more elegant solution. Need to be really really precise to not get duplicate panel lines when you repeat the process from different angles and orientations. I came to the conclusion it was less time and difficulty to add panel lines and small details to the physical model than to incorporate into the print (with the caveat that I’ve been doing fused deposition printing) Edited January 5, 2020 by LostCosmonauts 4 1 Link to comment Share on other sites More sharing options...
Sting67 Posted January 5, 2020 Share Posted January 5, 2020 Watching a few Youtube videos on the Anycubic Photon (for example) the print quality seems to be that good that you are able to print even tiny pieces in 1/72. The second half of the video shows examples that have very small details. 4 3 Link to comment Share on other sites More sharing options...

Serkan Sen Posted January 7, 2020 Author Share Posted January 7, 2020 (edited) Recently I have received considerable amount of private messages about the current status of Italeri A-12 Oxcart and Revell Flanker conversions. To be honest I made no progress on both since I have jumped into virtual modelling world. But now it's time to go back to real world... Today I did some progress on Italeri/Testors Oxcart conversion and reported here: I will continue to update this thread in parallel.

Kushan_Farsight Posted March 6, 2020 Share Posted March 6, 2020 Has this progressed any further Serkan? Any trial run prints on the smaller parts yet? Just looking at your seat model again, i wonder if the 'D-Ring' might be a little too small/thin diameter when printing at 1/72? I fell down a hole of reading about the Sr-71 satellite launcher last night and went to bed dreaming of 'what ifs' and came back to this thread again 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted March 6, 2020 Author Share Posted March 6, 2020 I haven't made any further progress on this project. I am currently working on A-12 and M-21 conversions to finish them to be able to have more time for 3D business: You are right that the seat has very tiny parts which are most probably not possible to print in 72 scale. But they can be a little bit oversized to solve that problem. And who knows, in one day I might decide to print in 32 scale 😁 Serkan 6 Link to comment Share on other sites More sharing options...

Who knows, it might convince me to buy a printer and learn the necessary design software. Something this old dog has no time for 😂 Dear Bill, Almost one year later your wish became real. I dedicate this post to you as an early Christmas gift: As a last Christmas gift I got a 3D printer from my wife and daughters. This year during Black Friday offers I have seen that a new version of my Elegoo Mars (Pro) was only for 180€ and I wanted to get it. But my wife made me remembered that I haven't opened the existing ones box yet... Of course she was right (as always) and to deserve the new model I had to show my skill that I am capable of using such tool... I have decided to make some test prints using my 3D Blackbird model. I have selected first the nozzle assembly to print. The first step was to add supports to all nozzle parts and export to stl file to process them using chitubox tool: After calibrating the device I sent the first print job to printer. As you can expect the first print was a total disappointment. Of course this was because of my lack of experience and impatience but not the fault of device. After few iterations we got used to each other and the first acceptable results appeared: The nasty part is to clean both part and holding plate with IPA after each print job: Serkan Edited August 13, 2021 by Serkan Sen 8 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted December 23, 2020 Author Share Posted December 23, 2020 (edited) The evolution of print skill and model can be seen from below examples. First the nozzle and tertiary doors area: Also the exhaust area required some modifications especially increasing the wall thickness to print the part error free: Printing the compressor stator and rotor stages was really challenging: The first few attempts failed because of extremely thin blade shapes: But finally I managed to print these tiny parts successfully. Next step is to print intake assembly... Serkan Edited December 24, 2020 by Serkan Sen 13 Link to comment Share on other sites More sharing options...
