Has anyone used these guys?

Next up, sharks with frickin' lasers!

This division of the company looks to be about 2 months old. They have about 400 Facebook likes and no product reviews so I'm guessing not too many people know about them. Good find though, the products look interesting and made in the USA. Although, the claim to "print like ABS" and then requite 240°+ temps is not really printing like ABS.

Too bad this stuff is twice as expensive as regular ABS. And since they don't list its properties in a data sheet, it's probably not much better.


There was a kickstarter for a 3d printer claiming to print carbon fiber filament a while ago. It turns out that they're going to sell the stuff for 25 dollars PER CUBIC INCH. Just as a reference, trimmer line nylon costs about 40 cents per cubic inch. 25 dollars per cubic inch is more expensive than having a machine shop make you a one-off, and if it has to be printed I'd get it sintered full metal from Shapeways or something.

I doubt their hotend is too special, either. I think any high temperature hotend can print fiber filled thermoplastics.

Just looking at one today. https://markforged.com

Was kinda excited at first until you looked deeper and saw that what you were getting for 5x the cost of an RMax was a fairly small build volume gantry printer with two extruders that would only run their proprietary software with their proprietary (and insanely expensive) filaments. All these claims about insanely good strength etc but, in the end, it's a thermoplastic with some reinforcement and I'm struggling to work out how you couldn't use the same or similar filament through an RMax with an appropriate nozzle size.
