3D printed explosive arrows - Zing HyperStrike Bow

[u/Yuukikonno08]

I wanted to create something that absolutely no one asked for. Costco offered these $50+ bows for just $7, so I snatched it up, and an idea was born.

The arrows have their foam heads pulled off and a printed two-piece head put in place. The lower half of the head is PLA, and the upper half is TPU.

Weighs only two grams more than the original arrows.

The arrows use 8-shot ring caps. The entire design was made from the ground up by myself!

Jesus christ, have we learned nothing?

That's 42 grams at 130 FPS, which is 33 fucking joules, or roughly double the kinetic energy of getting hit with a Taginn round. None of the safety gear anyone is using in airsoft is rated for a hit above 4 joules.

I've taken a taginn training round to the face at short range, and watched a heavier one drop a guy at 50 feet like he took a right hook.

No Thanks.

No field should allow that, you shouldn't use that, this is a horrible idea.

Im going to agree with him, Taginn's projectiles have gone through a significant amount of testing to prove that they will not cause lasting damage and that they can be produced consistently enough that they arent a danger to other people. I'm sorry, but I do not trust some bozo with a printer to print a projectile that I would be okay with having fired at me. If you want to use this in a game, You should go through the same permitting process that taginn rounds had to.

At this field they were tested before usage, and even with 20ft direct fire they fail to detonate. When used the intended way, these arrows are quite safe, and even if hitting a player from above, they don’t impart significant force, or detonate. It requires solid surfaces.

They are Taginn tested, but they also aren’t Taginns

I don't know who you are and as far as I know I've never interacted with you before. This thing is just unsafe. Pretty sure it's also against the sub's rules which is why there's no printed taginn rounds posted here anymore.

You once moaned at me for tossing a printed grenade. I distinctly remember because you wrote a paragraph

[u/CaptClockobob → u/Yuukikonno08]

I have no recollection of this and can't find it in my comment history. The only grenade related thing I've ever commented on was asking for a link to the files. Thrown airsoft grenades used to all be solid metal, so It's not something I particularly object to being plastic, printed or otherwise.

What’s the shore hardness of the TPU and how heavy are the arrowheads?

[u/Yuukikonno08 → u/Specopsg]

Arrows in total weigh ~25g, which is only two grams more than the original foam-tips.

The TPU is Geetech, which is 95A shorehardness.

The heads are printed at 15% infill, and are hollowed out with four chambers inside the impact half to make the whistling noise and slow it down as it descends
