Raise3D N2 3D Printer with Dual Extruder

I bought this after having used a number of 3D printers (Robo 3D+, QidiTech dual, FlashForge Dreamer, Rova3D Dual). It is whisper quiet, 12x12x12 build plane and fantastic print quality. I had a little trouble with ripples in my prints until I realized that I needed to clip the build plate to its platform. The build plate is a glass plate with buildtek on one side. You can flip it to the glass side when printing PETG or similar material that prefers clean glass. This printer also reaching much higher temperatures that my previous printers. This is the first printer that I've been able to print Ninja flex on without modifying it. I absolutely love the transparent filament feed system. It opens easily with a few well placed screws. I did notice that flexible filaments need to be fed slowly or this feeder jams. But its easy to clear in a couple of seconds by removing the aforementioned screws. Easiest jam fix ever! As you can tell, I'm absolutely in love with this printer. Well worth the money. I've loved my other printers. But this one is on a whole new level.

This is a great large format printer. We received this several weeks ago, it has been powered on and busy 24/7 without a hitch. The enclosure itself looks clean and industrial and the maintenance of the printer has been minimal so far with non-stop projects. The only reason we do not give this a 5-star rating is the 150mm/s speed. Where most of the other printers are doing 200mm/s. This 25% slower is felt on every print. But, otherwise, we absolutely love this printer. Quality, reliability, usability, all 5 star!

This is a well built, well designed printer. Solid and quite. Started printing within 1 hour after unpacking. It took an hour only because I had to learn the IdeaMaker slicer first. The LED lighting is a nice touch. This one has an XY axis vibration, but I'm hoping we can resolve that quickly. Support is very responsive and helpful.

I wish I could give this printer an excellent review but we have had so many problems with this printing properly I can't even begin to know where to begin. We are part of an Engineering Services company and my team has spent so much time with trial and error that I could have taken all the $ lost in productivity and bought a new printer. It will print test blocks great and then when you print the actual part you want it is issue after issue. We haven't even been able to repeatably replicate some of these things. At my wits end.

Slow and reliable. We have had XYZ printers and the gloppy Formlabs resin printers. So far, this is the most reliable, but quite possibly also the slowest. For us, reliability wins over speed every single day.

I have been using my Raise3D N2 for about 2 1/2 years. I now have 2 N2s and each needed to be set up and tuned in. I even replaced the extruders and reworked the print beds to be adjustable on the fly. Why all this work for a new printer? Because once it is dialed in it is a true workhorse. It prints fast and reliably. However, it will not print fast or reliably with the factory extruder. Get the BondTec BMG extruder. This is the most needed fix on the printer. In fact, their own new Pro series will be using the BondTec extruders (or a reasonable facsimile), but (A) they are not yet shipping [as of Apr 2018], and (B) They cost a lot more.When i bought my first N2 I could not find another enclosed dual nozzle direct drive printer with a removable print bed that could print 12x12x12 with any filament on the market anywhere near this price. So the upgrades were totally worth it and a minor cost. The downside is that if you are not familiar with 3D printers, you really may not want to get this deep into modifying a new printer. When I first got mine and ran into the difficulties you are having I wanted to return it. Glad I didn't and that is why I bought another. I have printed nickel sized nylon gears with a 0.2mm nozzle at 20mm/sec and footlong parts with a 0.8mm nozzle at 100mm/sec. I have printed extensively in ABS, ABS+, PLA, ASA, Nylon (Taulman 911), PETG, TPU, and HIPS. Using the BondTec extruders I have had no jambs or clogs.The actual material and components of this printer are extremely robust and rigid. Oh, and something to think about too, nearly quiet. I can have two printers printing away behind me in my office and not hear anything but a very low background noise that tells me they are printing. If that sound changes in any way, it is just enough to alert me to a problem. And that is another plus. You do not want a silent printer no matter how much you think you do. Very low sounds carry information you need such as the fact that material is extruding and you walked away to let it clear the nozzle. You may forget what you were doing, but the background sound will sooner rather than later bring your attention back to the fact that you left the extruders extruding! Seriously.One word of caution about these printers: They have quality issues only in the form of assembly. I found loose bolts on the drive carriage and both carriages were misaligned on delivery. Also, the print bed was not level. All easy fixes IF you know that you have any of these problems.One more surprising omission that they now are shipping a fix for, and that is thermal runaway protection. The printer, as it has been shipping up until now, had no way of detecting whether or not the hot end (the part that melts the filament) was overheating due to a broken control wire. Make sure that yours comes with factory installed thermal runaway protection. If they had not started shipping these printers with this protection I would have taken away another star (or two even) as I consider this omission a potentially dangerous situation.Use the R3D community forums and the R3D Tech Support. Both have been extremely helpful. It is a shame that such a capable printer is hampered by what amounts to rather small problems. Even with the factory extruder, a correctly set up N2 will produce some very nice prints -- albeit at a rather slow speed to eliminate ringing.Realize that a lot of real world experience has been typed into a very short review here and that you may never read about the short comings of many other 3D printers in Amazon reviews.. Would I buy yet another Raise3D printer? Yes. I not only printer prototype engineered components, I also use these printers for short run production. When the Pro models have been out for several months, I will most likely buy those to create a printer farm.

Bought 2 of the N2 plus printers and in the 6 months we have had them, they have had multiple mechanical failures. Raise3D has sent the wrong part twice for two different problems and have been. Unless you are an expert user that can maintain these printers DO NOT buy.Problems feb - augPrinter 1 - Ribbon cable brokePrinter 1 - ribbon cable broke a second timePrinter 1 - Clogged nozzle after 45 hours of printer Raise3D premium PLAPrinter 1 - Constant staircasing due to warped X/y armsPrinter 2 - build plate is warped (visible light between glass and metal surface)Printer 2 - Second Extruder nozzle brokePrinter 2 - Software error causing the screen to be unresponsive.Both printer spool holders constantly grind into the plexi-glassWe ordered run out sensor (because why build these into a printer that prints 1ftx1ftx2ft) they sent us the wrong runout sensor.They sent us a replacement extruder board and the board itself had a bunch of extra material on it (like it wasn't cut properly) which was a massive headache to install.They sent us 2 replacement ribbon cables (we had to purchase) one of them has a pinhole in it.
