The Type A Machines Series 1 gets heavily used in a design/production environment here at Zheng Labs. I'm truly impressed with this machine's reliability, ease of use, and print quality.
Leveling the print bed is insanely easy. Twist one knob, and you're The machine maintains its calibration for like, forever. In several months of owning this machine with daily printing I can count on one hand the print failures that could be attributed to the printer. I've seen one-- ONE! filament jam the whole time I've owned this bot.
Whatever small hiccups I've had with the Series 1 have been addressed by support quite quickly. These were mostly networking issues during setup.
The Type A Machines Series 1 is my third 3D printer, after a Makerbot Replicator 1 and a Printrbot Simple Beta. Since buying this printer I spend way more time printing and iterating designs than I do troubleshooting a cranky machine. Productivity's way up over here.
Check out the Beast Token torture test print attached to this review and look at how the Series 1 handles fine details and overhangs. This model was printed with Cura's default "High Quality" settings, minutes after I set up the printer.
Clever-eyed viewers will note the stringing on the print; I didn't quite have my slicing settings dialed in when I did this.
