crincon Posted April 1, 2021 Share Posted April 1, 2021 Hello all, Currently working on a GWH 1/72 F-15C. Excellent kit with lots of details and great fit but as it appears customary in this scale GWH choose to model "cropped intakes" that are completely inaccurate. So I took it upon myself to design proper intakes and 3D Printed them. Here are the results: I am now working to perfect these and since my intent is to model an open engine bay I'm tackling next a complete 3D Printed F100-220E... 😎 Quote Link to post Share on other sites

crackerjazz Posted April 4, 2021 Share Posted April 4, 2021 Very cool seamless intakes, crincon. Following along. That looks like Fusion360? And mind if I ask what printer you're using? Quote Link to post Share on other sites

crincon Posted April 10, 2021 Author Share Posted April 10, 2021 All too predictably the most challenging part of this project has been the F100's variable geometry exhaust nozzle... Quote Link to post Share on other sites
Major Walt Posted April 11, 2021 Share Posted April 11, 2021 I’m admiring the exhaust nozzle. How did you get that intricate detail on the surfaces. Emboss tool? Very inspiring. I’m relatively new to Fusion Quote Link to post Share on other sites

I’m relatively new to Fusion You can do it in a number of ways, I tried emboss at first but the resulting geometry was "non-manifold" and that in turn meant it likely would not 3D print. Ultimately settled on constructing the basic shape of the nozzle segment using 3D sketching, loft and extrusion (1). I then "cut" the detail midway thru the shape (2) and then used rectangular pattern to reproduce it (3) as shown below: Hope it helps!

crackerjazz Posted April 19, 2021 Share Posted April 19, 2021 You're something else, Crincon, wow! And your Orange10 can do that, amazing. What layer height is it set to? Quote Link to post Share on other sites

What layer height is it set to? Thank you! After a bit of trial and error I settled on a layer height of 0.10 mm for the "seamless intakes", 0.05 mm for the core and augmentor and 0.025 mm for the inlet fan and exhaust nozzle. Slicers used are Chitubox and Lynchee. Quote Link to post Share on other sites
crackerjazz Posted April 19, 2021 Share Posted April 19, 2021 0.025! That's some capable printer you got there! Quote Link to post Share on other sites

For the ISOGrid pattern on the augmentor and the lower portion of the core I followed the same methodology outlined on this video tutorial... For upper "slanted" portion of the core I had to basically devise a manual variation of the video above. Hope it helps. Quote Link to post Share on other sites
