Great reporting, Ann. Any idea how much more a multi-material printer would cost? Is it 2X? 3X?

Some day, I want you to tell me how in the world you found this story.

I feel the 3D printing option has already started to play the game. The innovation has started with so many compliments towards it. 3D printing will surely be embraced by many in the future and it wont take long to make things which we never expected to be.

Great innovation idea.  I'd love to hear how it sounds.  It would be interesting to see how responsive its dynamic range would be over the audio spectrum using these types of materials.

@Greg: Yes me too. Anyway I think the sound quality will be the same since it cannot be enhanced by 3D.

Excellent point.  The primary function of a speaker is making sound, and nothing about sound is mentioned in the entire article.  It seems that most articles about 3D printing only talk about how they look and not how well they function. They also never mention how much the equipment cost to design and make the parts or how many units wound up in the scrap barrel to get the one good one in the photograph.

It is a very nice use of the 3D print to make the speaker, but let us be real - like every other product it does use other technologies too. 

Somehow the media, the blogs and commentetors on the internt all make the 3D printer something it is not.  Sadly the common person feels that what ever they want can be printed and used.  I think we are very far away from that reality.  For example the other day - I had a Dean of an Engineering school talk to me as if he can get his body parts printed and replaced.  Now we know this so far from the truth, but that is what educated people believe, you can then imagine what the other common folks believe.  We are engineers and let us be real please.

Rungun, I believe that there is 3D printing being used for medical purposes.  I'm going off memory, but I seem to recall 3D printing being used to build a substructure on which to grow ligaments.

But your main point is well taken:  3D printing is a long way from displacing traditional means of manufacture, especially for mass production.

All that said, that is one *pretty* speaker.

jcbond_mi:

Thanks for your response and at least I know someone else who shares my main point.

I have read about growing tissues with a 3D print scaffold as a support structure, but that is not the same as printing replacement tissues.  (I heard enough of people who come up to me and say 3D printers can print tissues and they believe that a doctor can print tissues, organs etc and do the surgery and send you back home....


Like many other technologies that have come and gone, I am unable to predict how far this will go.   I think on of the major issues will be what loads, stresses and strains the finished product can handle. 

I used 3D printing first in 1992 and I am excited for the technology and am using it now too, but I am not a friend of the hoopla around it.

If you have some familiarity, perhaps you can answer this:

I used to work for a company that does outdoor LED signs.  Like every other company in this business, they purchase the LED's from China.

I was wondering if we could 3D print the LED's on the circuit boards and actually manufacture the LED tiles to order.  I did a little research, and it did seem possible (but maybe not cost effective).  Do you know if it is?
