Join the 3D printing revolution with this Dual Extrusion 3D Printer from Monoprice!

3D printing is the hot ticket now, primarily because it allows you to cheaply produce a design prototype prior to manufacture and, as can be seen from news reports, even make finished, usable products.

This 3D printer features a dual extrusion head, which allows for two color print jobs. It can use 1.75mm ABS, PLA, and PVA filaments and supports layer thicknesses from 0.1 ~ 0.5 mm. The extruder can be heated to 250°C and the metal heating plate can be heated to 120°C. It prints at a rate of 24cc per hour.

The printer comes with two 1kg reels of PLA filament.

Support Files:

Steep Learning Curve

Pros: Lots of good features for the money compared to other units on the market, seems sturdy/good quality, replacement parts available, based on a common design so not too hard to find tips online

Cons: The included documentation is worthless, as well as the free software that they recommend you use. Not a very easy machine to setup/use...I would not suggest buying one if you are unwilling or unable to tinker with things. No mention of ventilation or system to manage fumes. Very frustrating to use sometimes and can require a lot of troubleshooting to get correct results.

This is the first 3D printer I've used, I consider myself very tech savvy and mechanically inclined. I have spent years reading about 3D printing as the prices went way would I have spent $3k on one. However as the price dropped on this one I decided it was time...I bought this to learn on. I assume most people are not looking at this unit for "plug and play," I knew what I was gonna be in for when I bought it. The initial setup out of the box is fairly easy. However the documentation included is not worth the paper its printed on. Also, the demo files included on the SD card are setup for ABS...but the machine comes with PLA...don't ask why. Leveling the build plate is a little tricky and in my experience requires a few run throughs of the same procedure to get perfect...and if you don't get might as well forget about making good prints. I have spent a lot of time online finding answers to my questions to troubleshoot problems...because for the most part with this device you are on your own. Fortunately if you look up Flash Forge Creator X and Replicator 2 info, you will be on the right track...but again what you are reading is from other users...some of the info may work for you, some may not. I was having problems yesterday and determined I had a clog in the right extruder. Taking it apart was not a big deal...but you know I wish the manufacturer would provide a service manual for all of these procedures...because you can pretty much expect to have to troubleshoot this thing from time to time...I found a YouTube video from a user and was on my way. I had issues with sticking to the build plate with PLA at first...I had painters tape down but still did not always work. I read a tip online about using alcohol to prep the bed between prints, and this works wonders. I have not messed with ABS yet, because even after owning this a few weeks I feel like I don't have this quite down predictably enough to try it out. I have tried out several different PLA filaments though. Have not tried a dual color job yet.

Out of the box I planned to buy Simplify3D as my software for this, and just buying this software cut down my problems quite a bit...worth the money. I wish Monoprice would make a bundle of the printer with the SImplify3D software, with a bit of a cash savings, would make the open source software out there is complete garbage.

Not many people touch on fumes or venting this thing...even though PLA does not have an offensive smell I feel like "better safe than sorry" would be the smart way to approach would be responsible for the manufacturer to make a point to make appropriate suggestions...even to sell me another product...fine, as long it works. For the time being I have my printer setup in a spare bedroom near a window, and I run a window fan set to exhaust. Seems to work very well, you can't smell anything unless right up on the printer. Will probably want to look into a fume extraction system because having the window open is not always practical, and may effect print quality... especially as winter is here.

Would be nice if the included firmware allowed you to change the temp settings of the file on the SD card so you are not constantly going back to the computer to make adjustments.

Nice unit for the price

Pros: Seems to have all the features one could want.
Nice price for a dual extruder w/heated bed as compared to other units.

Cons: Manual sucks!

Being new to 3D printers it took me a while to get things working right. I couldn't get any prints to stick to the bed no matter what I did (blue tape, higher extruder/bed temps). Nothing worked. Finally, after trying masking tape instead of blue tape, and having the tape's glue stick all over the kapton coating, I replaced the kapton tape and tried purchased a different filament. Now prints are sticking like they should. ReplicatorG also seems somewhat iffy, but gets the job done.
For those of you thinking about 3D printing remember this You either have to download someone else's files or learn CAD to design your own. After downloading several of the so-called free CAD programs and having issues with almost all of them I finally downloaded FreeCAD and am very satisfied with it. Make a design, export it as an STL file, load that file with ReplicatorG, create gcode and print.
I rated this with an 8 because of the crappy manual and steep curve on getting prints to work (though that may be true with any printer). All in all I like it and would recommend it.

Pros: Works as expected
Great price for features

Cons: Terrible Documentaion
Yes, the SD card location is awkward

I've been wanting to get into 3D printing for a few years. This printer is the same as the Flash Forge Creator Pro, which currently costs about $1000. I think it's a good starter machine. The machine is producing my fourth big print. The results have been outstanding. I had modest expectations. This printer has exceeded them. The documentaion is terrible, nothing more than how to set up the machine. You'll have to go online and look up the FF forums on how to use it.

Worth it...

Pros: Price, heated bed.

Cons: SD card slot location. Kapton tape on bed.

I'm familiar with the Replicator 2 as well as the 5th Gen from Makerbot. I much prefer this to either. The advantage over the R2 is the heated bed. Even though I am familiar with 3d printers, I still had some learning to do. I could not get the first layer to stick on the bed with the incuded kapton tap. I re-leveled numerous times, experimented with many different bed and extruder temperatures and had about 1 successful print out of 20 or so. Ignore the test prints on the card if you're using pla. I finally used my blue tape (that I use on the Makerbots) and turned the bed heating off. Instant success at several different extruder temps. I figured I'd paid for the heated bed though, so I spent 99 cents at the hardware store to get a 6 1/8" x 9 1/8" plain glass plate (2.25mm, according to my calipers) made. After printing a shim for the z axis height (hot melt glue works there) and buying a can of hairspray (couldn't find the industrial Aquanet so I bought the industrial Suave), it was off to the races. Every print sticks just fine now. I print pla with a bed at 60 and the pla at 205, although I'm trying to lower that. It was originally set at 230 and I'm dropping it 5 degrees each print. My guess is I'll end up below 205.
I don't know how often I'll need a second extruder. I may remove it (can it be used as a spare if the other one dies? Are they the same?) or just remove the nozzle so it doesn't interfere with the primary extruder. I've also ordered some spare nozzles on Amazon, just in case, so I don't have to clean them. All together I'm happy with it so far (and it hasn't been a long time). For $630 to the front door, it is very worth it. There's no way I could have afforded a Makerbot for myself and I was looking at kits and lesser printers in the same price range. I have not run any abs through it.

This isn't easy!

Pros: Price
Dual extruder

Cons: Lack of auto bed levelling
Filament holders make the spools rub each other and increase friction
Manual is awful

This is my first 3d Printer, so I am by no means an expert. I read the unofficial manual that was linked in an earlier review and had myself all set with hairspray, painters tape, you name it. First important point: The test files on the SD card are NOT configured for PLA. They heat the bed waaaay too hot and the filament temp is not right. So don't just level the bed and try one of those :) My next tip is the heat for the black PLA included is best at 190c. Seems low but I get a lot less stringing that way.

My main problem though is dragging between the heads. If I'm printing a larger piece and the second extruder head bumps the print it's often all over and turning into a gloopy mess. I often wish I had started with a single extruder machine to learn. I may take off one of the extruder heads to try and make it easier for now. I've tried printing probably 20 times and have about 3 successful prints out of the bunch. So no, this isn't plug and print at all. If you enjoy learning then this is a good way to do it.
