Yetti Posted March 25, 2020 Report Posted March 25, 2020 8 hours ago, Ah-1 Cobra Pilot said: To throw more questions into the mix, there are several different methods of 3-D printing metal. The most common is sintering layers of metal powder with a laser or electron beam. Another is blowing metal powder into a melt-pool created by a laser or beam. Structures of less than 10μ m can be built with either and the resulting parts are between casting and forging in strength. Note that most cast aluminum cylinders typically have a hardened steel sleeve in them, as would anything 3-D printed. You did not need these in the old, cast iron blocks. The true beauty of the 3-D printing is the optimization of the design, including being able to better fit any aircraft with better strength and better cooling with lighter weights. The present detractor is the price. 3-D printed products usually cost at least $1/g-$5/g. Once that comes down, we will see a revolution, except the FAA will be there blocking it. Ha ha you said revolution and FAA in the same sentence. Funny guy. 1 Quote
carusoam Posted March 25, 2020 Report Posted March 25, 2020 Let’s look towards the experimental world for guidance... 1) If we could get better cooling... 2) If we could get better packaging/fit under the cowl better.... 3) What else could we get or need... There would be some upside worth chasing... Cylinders seem to be manufactured often enough... it could be considered mass produced.... cost opportunities of numbers... PP thoughts only...

aviatoreb Posted March 25, 2020 Report Posted March 25, 2020 Aside - I think really amazing are the soft materials 3d printing technology. Like this working heart valve https://directorsblog.nih.gov/2019/10/10/3d-printing-a-human-heart-valve/ Quote
