China’s home-built C919 jet receives 815 orders from home and abroad

How do you know that?

Also, 3D printing is now applied in all advanced processes according to need. Also, 3D print by itself doesn't mean efficiency.

Again, I am saying nothing, just reserving my judgement for the future. The actual results can only be known by independent third party testing and operation.

How do I know? As if I make up all this? The chief designer of C919 says it. China is leader of 3D printing. You are naive to think all 3D printing is same. Material use, size and quality? They are all different and China is world leader in 3D printing. The bigger u 3D print it. The more technical challenges it is. 3D print eliminates bold joint and traditional welding. Therefore reduces weight and strengthen groundwork. It is critical especially in aviation building where weight reduction is important.

Western stupid source jealous of rising China will badmouth and claim C919 is outdated and full of BS. This is the upbringing and their civil moral. Lying and smearing when they cant beat you fair and square in competition.

Wow if @Bussard Ramjet is more of an expert than the C919 chief designer is, then we have lost all the credibility. What a shameless liar our aviation leader is, time to throw him in jail and discipline him

No dude. I know very little about aviation in general, so I am very low on expertise. I am just trying to judge what the technological scenario will be from the data available to me.

Now, I think the chief designer of C919 is surely infinitely more skilled than me, but don't you agree he is a biased observer?

That is why I said, the aircraft needs more third party independent operation for us to actually found out how it performs. I have no doubt on the expertise of the designer, the only problem is that he is a biased party, not a neutral party.

how it performs? You trying to say our experts didn't compare the results? How hard can it be? We already bought boeing planes, run the efficiency tests on the American plane and the C919 and make your own judgement.

Did the source you got your data from perform any test on the C919 before jumping to the conclusion that it is decade behind? Isn't that biased then?
