Isn't this basically what D'addario did with the reserve mouthpieces? They also have done this with whole instruments like the Eos Stradivarius violin. Would love to have an old chedeville though.

Yes, it is for real; already used for delicate precision parts at NASA and elsewhere. Synthetic reeds can readily be reproduced, but cane is another matter. MP, why not ?

@richard: not so simple.. 3D printers use thermoplastics for printing. D'Addario used similar process, but they CNC Reserve out of hard rubber, not print.

CNC machining and 3D printing are very different. 3D printed blanks are still going to need to be hand-finished to be playable. Exciting that it will be easy to easily produce a wide range of blank shapes, but to my knowledge 3D printing tolerances are still lower than injection-molded plastic.

Investing in companies that are developing 3D printers probably a very good idea.

hmmm,
sounds like a thread that was already started! Good one Ken.

(Disclaimer - I sell Chedeville brand mouthpieces, Chedeville is a registered name mark and trademark)
3-D printing is amazing and no doubt will replace some areas that precision CNC machining is used now. A couple of problems as pointed out that a thermosetting plastic is used now in the process of 3D printing and the other is obtaining exact measurements to tell the printer what to make. I guess that 3D printing would add information as to whether the material or the architecture of the mouthpiece is an important functional property. Getting very accurate measurements of the outside of say a classic mouthpiece is not hard with today's laser scanning technology but getting precise measurements of the interior is very difficult and sometimes Computer Axial Tomography (CAT Scan) is necessary to get digital measurements.

What are the Intellectual Property Rights issues here? Does 3D-printing of a mouthpiece infringe on any patents/copyrights/trademarks/etc.?

I am not a lawyer but there are patented aspects of some commercial mouthpieces such as the composition, some architectural components which make them unique, as well as processes to make the mouthpieces. Some companies have registered names as name marks and logos which are copyrighted and/or registered nationally or internationally which would preclude their use in or on a 3D printed mouthpiece. A patent, copyright or trademark is however only as protected as the zeal, desire, and litigation used to protect it.

Any Chedeville patent will be long expired. Trademark law covers only the use of a trademark. Copyright law covers only the use of copyrighted language.
Many current mouthpiece makers advertise that they reproduce original Chedevilles, and Rick Sayre reproduces the original trademarks. I don't think he has a website or Facebook page, but he runs an ad in each issue of The Clarinet, showing his imprints.

Three questions on 3-D printers
1)Can a 3-D printer print a clarinet?
2)Can a 3-D printer print a 3-D printer?
3) Can a 3-D printer print money?

More than you wanted to know:
I worked in a shop that helped support some of these machines up to 2005. There were two kinds: FDM (fused deposition modeling), which fuses and deposits material from a spool of plastic wire in successive layers; and SLS (selective laser sintering), which uses a laser to sinter or solidify the desired areas of successive layers of plastic powder. The proper name for these things is "rapid prototyping" machines.
Both processes produced plastic parts with low density, a fairly coarse surface finish and tolerances in the .005" to .010" range. These parts seemed appropriate for their suggested purpose, which was to make a solid object from CAD data that you could inspect to critique the design. A good example would be a car door handle - you could test the feel of the grip before committing to tool and die work.
qualitycontrol is correct in saying a blank would need finishing, inside and out, and the materials I saw were not up to snuff in their mechanical properties. It felt as though I could have broken the parts easily with my hands. But materials must be better now if they're making pistols!
I think high-end coordinate measuring systems would have no trouble digitizing
a mouthpiece, and repeatability is very good with the prototyping machines. But by far the lion's share of the work would be finishing the pieces without altering critical dimensions.

Hi Ken and all, a company name can be trademarked as well as a logo and any use of the company name, even associated with a person living or dead associated with a current produce using the name as outlined in the description by trademark law. Chedeville name (name mark) and logo are registered trademarks of the Glolden-Henderson llc. Suffering the use of the name or trademark associated with woodwind products does not grant a license to use the name or logo on any commercial product or a description of the origin of the commercial product unless prior permission is obtained and attribution cited in usage. Any unlawful use of the name mark or logo other than authorized is an infringement of the trademark and perpetrators should cease and desist this usage. The name Chedeville is associated with commercially viable products produced by the Chedeville Group of the Golden-Henderson llc for many years and is recognized as the name used in commercial usage for woodwind products. Prior use of the name Chedeville describing woodwind products is not accepted as a license to use the name by the trademark owner as applied to products in current production. The name mark for Kaspar has similarly been trademarked with equal trademark protection.

I just received an email ad from MicroMark for a 3D printer you can assemble yourself.

I think I recall Maxton (an Austrian company) is in the business of making accurate reproduction mouthpieces as well as new designs by using 3D computer imaging and manufacturing.
