As the 3D printed gun story unfolds, many (including me) have noted that you can't print ammo. However, you can print shotgun slugs on a 3D printer, but they suck:
Heeszel was surprised at the first two. “I didn’t think it would go through the first piece of wood at all, much less hit anything,” he says. But he also called them more of a novelty than a practical bullet. “I thought the thing was kinda lame, but I realize there’s a lot of novelty with the 3-D printed gun, and I thought it was kind of timely. But overall I think they’re kind of crappy little rounds,” he adds...
“I might be a redneck from Tennessee, but I love the technology,” Griffy says. Griffy, who runs a YouTube account ArtisanTony — where he also shows off a printable knife and buckshot rounds — tells Danger Room he printed the slugs more for their own enjoyment. “Because a real gun shooting plastic bullets is more fun than a plastic gun shooting real bullets,” he says. “You have to spend six hours printing a barrel that you’re going to use one time, and it’s not as much fun. It’s more about the enjoyment and the sport. And if you’re having to labor that much, then the enjoyment goes away.”
Griffy says he printed the slugs with a Solidoodle 3 3-D printer — which retails for $800 — using ABS thermoplastic using dimensions from one of Heeszel’s non-printed slugs. Griffy then created the computer-aided design files, converted them to a stereolithography format, and checked the files for inconsistencies with the 3-D printing software Netfabb. He also designed slugs in three sizes. The largest slug takes about an hour to print. The others take about 30 minutes. He also added a lead ball to each slug to give them more weight. The final step was mailing them to Heeszel, who fitted the slugs into hollowed-out — non-printed — shotgun cartridges.
