Bachi blade material

Hello All

Looks like I found the material closest to a “Pro” level bachi properties. It is a Polyetherimide (PEI) polymer. Material comes in different sheet thickness: 0,8mm, 1mm, 2mm, 3mm etc, semi-clear, amber color. I have seen black version as well. I have been playing with two pieces of 1mm PEI glued together as I did not have correct thickness material laying around. I compared it to “classic” bekko or faux bekko bachies for hardness, flexibility, wear, bending force, “springy” feeling and it seems to be a really good match. It is expensive, way more expensive than acrylic (but not as bekko bachi :sunglasses: ) and a bit fragile (close to acrylic, maybe a bit less). I would say it is overpriced a lot due a popularity of this material as a bead material in 3D printers.
I have ordered a 3mm thick piece and going to build a test bachi as soon as I receive the material.
Just curious if anybody tried it as well.

Nice! Since you have the opportunity to compare materials, would celluloid be any good? Thanks! :slight_smile:

I have tried celluloid. It is too soft and would not hold the shape and will deform under the string strike bending force. I the end it would get curved to one side (away from the strings). The real bekko surprisingly hard and quite flexible at the same time.

Ah, that´s a bummer, it has such nice patterns… Thanks for the reply and good luck with testing the new material!

@Alexey, did you ever try out the PEI? If so, how did it work out?

I played around with a small piece I have got and liked it a lot. Have no time yet to do a full sized version.
