Hey folks,

I tried to add this to the previous thread about my new instrument for Jeff Titus (Taproot), but I've been unable to post a message to that thread, so I'm trying this as a new topic.

I've finally gotten a little video demo/tour of the features of Taproot up on YouTube.  I'm not sure what the best way to post it here is...here's the YouTube URL:





Enjoy!

Fred

Simply amazing!  Nice work Fred!  Looking forward to hearing what Jeff comes up with on this beauty!

Dear Fred, with this instrument, you take my dreams up to new heavens. I couldn't imagine this could happen. All my respect.
Philippe

I had just decided to build one of those but GAL doesn't have the plans yet.  Maybe you could push them along a bit . Thanks..

I have tried to respond to your video several times but words have failed me. I shall refer to you in the future as Fredaelangelo. You will live forever in your art.

Many thanks, my friends!!  Merci beaucoup!

Boy, it would be a project to come up with workable plans for that thing!  I did, of course, have tons of drawings and plans, but they were in constant flux, flowing with the development of the instrument.  Mostly, things stayed pretty true to the original sketches, but there was a lot of wandering around in the mystery-zone before coming out into the light at the end of the tunnel.  And of course, once it "settles in", we'll still need a few years to see how all the choices I made hold up in the real world!

Jeff and I have been talking about 3-D printing of an instrument (really, it can be done!  Print an instrument using a 3-D printer!)....but somehow I think Taproot isn't the design to start with for that adventure!

3D Printing? A working guitar, or just a model? Or are you only talking about selected components? Out of what material? We have several different types of RP machines at my work and I can't imagine how a whole instrument could be possible (it would also be wicked expensive).

There's an amazing video I've seen...don't have the link off hand but maybe you can google for it, of a violin printed out of some kind of resin.  The process apparently was one of first scanning a Stradavarius with a 3D scanner, then some tweaking with software, then printing the entire instrument body, neck and maybe also fingerboard.  Some handwork must have been done to clean it up, and then pegs and a tailpiece and bridge were fitted, strings added.  It sounds amazingly good in the little demo.  Jeff(Titus) claims that there are a wide variety of materials that can be used for the printing...wild stuff!

A department in my company have a variety of 3D printers. One of their eye-opening "prints" is that of an insulin syringe made from a laser cured resin. The syringe pen consists mainly of an outer housing and an inner part that screws into the housing via a spiral thread, i.e. when you twist the inner part it travels into the housing. Anyway; the syringe was printed in one piece and the only cleanup done afterwards was spooling off the uncured plastic, leaving a nice satin surface. Seeing how basically a threaded nut and bolt is printed already screwed together is simply surreal.

p.s. We make oilrigs not insulin pens . I think it was a favor they did for Novo.

p.p.s. And "wicked expensive" I think is *thee* word to use.

p.p.p.s. Extremely cool video, Fred, that played many times here at home !

Hi all... sorry I've not read this one until now. There are actually many ways to get 3D printed guitars produced... and it's been done many times, for years.

Here are some examples:

http://www.odd.org.nz/index.html


http://redeyeondemand.com/

Of course, these are electric examples, and what I'm counting-on here is that Fred will have a design that others have not yet imagined that would go fully acoustic. He's good at that sort of thing, y'know.

Another approach, besides direct printing of the guitar itself, would be to print the mold in component parts to exact specs of the design you have in mind.

With regard to the materials... I don't believe that the large scale printers like at redeyeondemand.com are doing this yet, but a place called Shapeways has stainless steel, sterling silver and all sorts of plastics, gypsum and other stuff. (sorry, no wood printers that I know of yet!) http://www.shapeways.com/materials

I have a few ideas of my own... and fortunately, Fred puts-up with my silly ramblings when I go overboard (then figures-out how to make it happen... as he did with the dulcimer hammers on Taproot mid-build!)

BTW... Taproot's features are real and they're fabulous.

It is a wild world!  Who'd ever thought we'd be printing guitars?

Jeff, I'm so thrilled that you're such a proud father of Taproot, and I like how you make it sound like that beast is just a working wonder of perfection.  No need, after all, to tell the world about all the blood, sweat and tears that have gone into trying to get it to work, and that continue to go into getting it to keep working as it settles into life with string tension and someone playing it in the real world!

The thing has a life of it's own, and we're stilling learning what it intends to do with it!

Like I said, it's a wild world!

Fred

We have the exact machine used for those Redeye guitars at my school. You have to understand they're really trying to sell the process, not the guitars.

BTW We charge the kids $10 a cubic inch. Personally, I'd rather have a wooden guitar.

Maybe Fred should start charging by the cubic inch!

Then I'd have to figure out how to figure out cubic inches in one of my creatures....Jeez...I have enough to do just picking fleas off my dog!!

Although it makes more sense, probably, than charging "per string", which started as kind of a joke, but turns out to be a reasonable way for me to make estimates.

Eeek!

Fred

I think as the scanning techniques improve perhaps we can inspire an army of Fred scans for inspiration. With Kinect Fusion coming to the SDK it will be fun to try on Oracle and Taproot.  http://www.i-programmer.info/news/194-kinect/5040-kinect-fusion-coming-to-the-sdk.html
