3Dresponse

[WHlTEDEVlL]

thank you hippy for clearing that up, i wouldnt care if you didn't either. stop view whoring. you ruined my life.

[Swearingworth]

The integrity and tenacity it takes to call out Nat Geo on there mistakes is inspiring.

On behalf of truth seekers, thank you.

[thrillscience]

What a horrible liar! I will never trust anything from National Geographic again. Z-Corp is a fine company; the culprit here is National Geographic.

[ronbo191]

Thank you David for being so honest. You are a rare breed and I hope others follow your lead......

[HalcyonicRepose]

Great follow-up video, the 3D printers are entirely capable of printing intricate internal shapes with the right input.

Here's a another brilliant invention, printing with GLASS (melted sand) using focused solar energy in the desert!

The desert could be a factory of the future, printing inexpensive building materials/etc ! (Need a building? Just print interlocking glass bricks!)

[wturber]

Well ... any reasonable person should have known to take the Natl Geo piece with a grain of salt as soon as this (quite cool BTW) technology was likened to science fiction replicators.

It is a shame to see this because the actual technology of the 3D printer is quite cool. It really doesn't need to "benefit" from ridiculous exaggeration.

It was good of dkapla that he posted a clarification. I hope Nat Geo sees this for the good thing that it is and continue to use dkapla where appropriate.

[thomasey2]

Right attitude, that is the way to go.

[puertoguiri]

Good on you.Thanks for your honesty...I wonder if the printer could print politicians............????

[wdmacr]

@puertoguiri

I assume you mean HONEST politicians.

[Ears14U]

Sincere, and integrity to match! Thanks for clarifying all that untrue crap!

[galimir]

and so iwhy they would do this fake stuff?i really dont get it?or its just america these days...

[TroyOi]

Hey David, thanks for this clarification. Yes, the scanning issue came right to my mind, and I just love it when a YT poster answers the obvious questions that his video provokes. As wlindenlaub just wrote, that tends to be rare. No need to rag on yourself for the original omission. You're just one cog in the wheel that made this video, and I think we as consumers of media should appreciate that the guy in front of the camera doesn't necessarily bear sole responsibility for the final product.

[wlindenlaub]

This is a rare video to see. What I thought was weird was that if they were showcasing the ability to print a 3 dimensional "tool" you would think that they would go for strength right off the bat for the simple nature of what they were demonstrating. Still a very cool technology and your honesty is very appreciated.

[taydubb]

Thanks for giving us the truth !! Wish we could just make more copies of you with a machine that's similar to that. Keep up what you do !!

[Shapeways]

Hey David,

You rock, if you ever need anything 3D printed please contact us at Shapeways and we will be happy to make it happen for you.

[Wizcrafts]

I suspected that what we saw needed manipulation in AutoCad to get the inner worm gear into the printing coordinates. The clarification is much appreciated! Now, onto the future...

What we saw here was what I believe is the first generation 3D scanner/printer. How long will it take to come up with a combination optical/x-ray scanner to get interior parts in the initial scan? Not long at the current pace of High Tech development. I bet we also see powdered metals with catalysts in next gen 3D.

[cirusMEDIA]

Thanks alot... this was soo needed!

This response sure clears it all up for me!

[gobo82ndc]

Thanks for posting this video and fighting misinformation with facts. Thumbs up!

[farooqmss]

exactly this question of inner structure was bugging me!!!

[CobaltDaydream]

WOw this tech will truly be disruptive. Whole new level. How long did the "printing" take. How much does one of these machines cost? I was surprised though. The hand scanning seemed rather "unscientific" lol. Amazing stuff!

[Angelena]

You are a very cool host/dude. period. Thanks for the refreshing honesty!!

[Ursenfuns]

"If you really wanna find out what's true, investigate more."

Can youtube install this as a permanent headline?

[nascarlurg]

Great guy....very professional....not a lot of other hosts would come on to set the record straight!!!...Bravo Sir!!

[sleekblind]

Good man. I assumed this was the case, since it is entirely possible to "edit" an object in such a program, and figured that whole process either got edited out, or they printed a similar object from a pre-existing file. Thanks for clearing it up!

[dontdispie]

So forgive me for being dumb but did we see a wrench get "replicated" or not? That was the implication it sounds like there were some more steps involved but if I were in a submarine and needed a crescent wrench could i "print" one with this technology or not?

[silvereagle2061]

your honesty is refreshing. thank you

[sunshineyogicom]

Thank you for doing this video and your honesty. The world needs honesty. Too many see something on the internet and take it as the truth, thus corrupting their minds. Thank you again.

[giantstepcomms]

Thanks for helping me maintain my sanity; I was wondering if I missed something! Glad to see others were THINKING and saw the same discrepancy and both David and Joe responded responsibly. A great product (also seen in a video with Jay Leno for reproducing classic auto parts that are no longer made) and now we see the limitations.

[mclaner]

Hey man,

I really appreciate you taking the time to explain that. It's an even better story now. It shows the strange interaction between machine, truth, and humans.

--Mac

[madfiddlebear]

Thanks for posting this, David -- it's always good to have the full story and be able to appreciate the real advances made with this technology!

[ZINTASTIC]

Actually spokybob, the only one the only one that come's across as a jerk is you!

Roz

[ericarainhart]

Also, no mention of the dollars cost/sustainability value?

[txstang84]

How did he come across as a jerk? when he said Nat Geo "needs to get their act together"? if the baby's ugly...the two separate technologies are pretty awe inspiring, but the way they were represented wasn't completely accurate-that's all he was saying.

[spokybob]

David: You come across as a jerk in your response.

[PiccoloKu]

Wow. I though journalistic integrity was dead, but David proved me wrong. Awesome response, thank you!!

[Paulie23]

Apology?

No need for that...wasn't your editing in the video

[joetitlow]

Joe Titlow from Z Corp. David - thanks for your response to the misunderstandings in the Nat Geo clip. We at Z Corp certainly never intended for anything to be deceiving and your explanation here helps to set the record straight. What was suggested in the video can be done today, but the complete story did not make the final cut. We spoke about the need to edit the scanned image during your visit, but inevitably editing our 4 hours of conversation down to 4 minutes, left out a few details.

[dkapla13]

@joetitlow Hi Joe - what was done was, I believe, for expediency. If millions of people watch, they are going to find the sloppiness. As far as I am concerned, no fault lies with you. You guys were great and are doing a great thing.

[morvarid69]

@joetitlow can you help me understand this? I get that if you try to print lets say, a spoon it will print it exactly the same, but what about electronics? What I mean is, if you "print" a camera, will the printed version still FUNCTION as a camera or does it just look like the camera? thanks

[robokill387]

@morvarid69 it will just look like a camera. it's really just a plastic replica of the object, so only mechanical objects can be produced in it.

[morvarid69]

@robokill387 Thanks! :) appreciate the answer

[Boshyworld]

Thanks for clearing everything up, I wanted this to be true so badly and now you've shown that the technology works I thik It's amazing even if it is "just" a demonstration programme.
