Grabner has a good rep and I can attest having his Eb,Bb and Bass zinners. I'm very intrigued by the new material compared to the old.
Most 3D printed pieces that I've heard have been interesting to witness but in regards to sound/tone they were very underwhelming IMO. The majority of the clips were sax players on SYOS pieces, however I found that notable players who played on them had a clear degradation in sound/tone(opinion). Although this is the clarinet we're talking about and furthermore Walter Grabner, who has a reputation of honesty and quality products.
I'm aware that this is a pretty new product and not many(or possibly no one) may have tried them, but I am very curious.

The material I am using is not an ABS or PLA. It is a new material, only available in the last year. It is a polymer, but to a non chemist it is best thought of as a nylon.
The acoustical properties, in my opinion, are in the same league as hard rod rubber.
An added bonus is that you can drop the mouthpiece beak down, on a concrete floor without any damage.
The actual printing is done on a Hewlett Packard Jet Fusion printer that costs over $200,000.00. The resulting accuracy rivals CNC development.
I will put more information on my webpage by tomorrow.

Wow Walter, that sounds really promising!
I take it the mouthpieces list for a little less than the machine?
Actually I do have a serious follow up question. Is it fair to say given the description you give of an EXTREMELY durable tip, that the facing will virtually NEVER wear down???

Well, Paul, I don't think I can make THAT claim, but it is a very tough, resilient material that will not slowly degrade, as rubber always does. I would expect these mouthpieces to last many years into the future.
In terms of the list price, I did not feel that it was necessary to charge more than my preexisting prices.

I played a Runyon mouthpiece made of an acetal resin on baritone saxophone for many years, but it was machined...not printed. Likely the material was very similar to the 'nylon' that Walter is using...great material and more comfortable to the teeth, being more elastic than brittle.

You are close, shmuelyosef, but acetal resin in actually Delrin. I have used, and continue to use Delrin in my barrel making. It is an excellent material to work with and has good acoustical qualities.
However, that is not what I use for my new mouthpieces.
This an excerpt on a webpage about various material that can be used for 3D printing. This section concerns PA 12, which I what I use:
Nylons are a common class of plastics that have been around since the 1930s. They are a polyamide polymer traditionally used in manufacturing for plastic films, metal coatings and tubing for oil and gas – among other things. In general, nylons are immensely popular for additive applications because of their processability, as referenced in the 2017 State of 3D Printing annual report.
"PA 12 (also known as Nylon 12) is a good general-use plastic with broad additive applications and is known for its toughness, tensile strength, impact strength and ability to flex without fracture. PA 12 has long been used by injection molders due to these mechanical properties. And more recently, PA 12 has been adopted as a common material in additive manufacturing processes for creating functional parts and prototypes.
It’s used in fused deposition modeling (FDM) as a filament, and in binder-jetting processes, such as HP® Multi Jet Fusion (MJF), as a powder. Proprietary forms of PA 12 have been developed for both additive technologies. HP®, for instance, created HP® 3D High Reusability PA 12 for use in its MJF process."
It is the HP 3D High Reusability PA 12for MJF (Multi Jet Fusion) that I use. I am also eveluating other material. If I selec any I will let you know.

I am aware of that material (hint: I studied Materials Science in grad school and worked at HP for >3 decades...retired now). Good choice...I look forward to checking it out. Your K14 is still one of the the 2-3 mouthpieces I fall back on for regular use (even though I'm very fickle)

Jeff -
I am also testing out the HP 3D High Reusability PA 12 Glass Beads. This also has a huge potential for an excellent acoustic material. I'll keep you informed.
