No joke. They built to withstand a pistol bullet (and demonstrate it) all on a 3D printer.
I have recently gotten into 3D printing, it is a blast, though somewhat frustrating at times. I have been using a cheap, Chinese Creality Ender-3 printer, and I got a lemon. after months of struggling, I finally got the bugs ironed out, but it served its purpose.
I didn't want to be one of those people who spends all this money on something and never uses it, so I bought this cheap printer for $175, and while I had no end of trouble with it, it was like owning my first car. I knew nothing about cars, but after owning a notoriously unreliable MG Midget, I learned all about cars.
Same with this printer. So I purchased a new one a couple weeks ago, a pretty expensive one, and purchased some real 3D software.
When I hadn't heard back a week after ordering it, I sent a polite email and left a call inquiring about the status. I fully understand with everything going on there will be delays, I just wanted to ensure the order went through.
The CEO personally called me back to give me an update, and the next morning, emailed me a picture of my printer being assembled...:)
(he said mine was the one on the left...:)
I like that. One of the reasons I chose the company was because the product was American Made, and the support experiences sounded like this call from the CEO-great customer service comes from the top down.
