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.
