    Man, You’re not going to believe it! This thing is a real tank. All the parts are steel making this a huge 3D puzzle..yes, there will be head-scratching. Follow the manual (which had lots of pictures) in order, and you won’t have any trouble. Except for the awesome structure and hardware, everything is pretty standard. The hot-end was nice and pre-built with a quick release for changing filament(Geeetech I think), no fooling around. I took my time building it, and it simply worked from the start (again, follow the 2nd manual in order). It makes a nice little music when it prints because of the metal structure. Like it says there is no plastic to wear, so once it’s set-up turn it on and press print. With MakerBot pushing their crappy breadbox for $1600, this is a steal and a no-brainer at around $500. The only bad points are minor..(1) it didn’t come with a starter roll of filament, and (2) the cable routing is a little shabby, but what can you do?

    I purchased one of the beta units, so I went in with the expectation that things were going to be rough around the edges, and was pleasantly surprised to find very few issues with the assembly process. Great manual with lots of photos. Everything fits together really snug, and all the parts are well secured. The result is a SOLID machine that is very quiet (with the exception of the quiet sound of the steppers doing their thing). Another nice thing about the metal frame is that I’ve been able to pick up the unit and put it on a shelf when not in use and then pull it back down again when I need to use it. No recalibration, bed leveling or Z-adjustment needed, which makes it a huge improvement over the original Makerbot and several other 3D printers that I’ve used. So far, I would say my experience with the it printing puts the i3PRO at the top of the consumer-level 3D printers I’ve worked with (a list that includes 3 models of Makerbots, a printrBot Metal, BFB3000 and an mBOT).

    I purchased this unit to replace another one and this one is so much better for less cost. It is built like a tank and can, so far, print t-glase and nylon without an issue. Customer service is the best with Makerfront and I would wholeheartedly recommend this printer – and I have so many times already!

    This is currently the best deal in 3D printers, bar none! Let me start with the assembly. If you have put together Swiss furniture, or even a Lego project, you have the skills to make build this magnificent machine. The instructions are very complete and well illustrated. Read through the instructions a couple of times while you are waiting for the box to arrive. When it arrives, have a clear bench top or table, and lay everything out and begin building. I had a couple of broken parts, due to the gorilla who handled the box at the Post Office, but an email got the replacements on their way to me in a matter of hours. As to what you are treated to when the build is complete – you will have an extremely sturdy and efficient 3D printer that surpasses everything in its own price range, and 4X beyond that, at least! If you have EVER thought about getting into 3D printing, this is the printer for you!

    I am very happy with my new printer. Construction is solid and performance good. Took about 8 hours to assemble, had to back up a couple of times but it was not a problem. I would definitely recommend this to someone looking to build a printer.

    Not much to add over what has been said already. I am incredibly impressed with this printer. I had previously purchase another (for work) that currently sells for almost $2000 (fully assembled, and it’s a fine printer), but this this is a quarter of the cost and seems just as solid. Putting the kit together was straightforward. I bought this one for my workplace as well, but will eventually be buying another for personal use. Very satisfied and excited about the purchase.

    The box arrived earlier this week and right now I’m typing this as I make my third print. The instructions are great (though the wiring info on the extruder motor is out of date), the assembly went smoothly, and configuration and setup were also fine. I would have liked one last set of instructions for first timers like me that would explain how to load filament, how to make my first print, etc. but I figured it out quickly enough. Most of all, this is a solid and sturdy machine and I am delighted with it.
