The Monoprice MP 300 Guider II is the bigger sister of the MP 150 Inventor II and also a perfect example of a high quality plug-and-play 3D printer. It even comes calibrated from the factory. Basically, all you need to do is take the printer out of the box, load the filament, plug the printer and start printing straightaway. In some cases, print bed calibration is required but it is done in less than 5 minutes with the assisted levelling function that can be followed step by step on the touchscreen.
The printer comes with:
The Monoprice 300 Guider is an FDM/FFF (Fused Deposition Modeling) printer with a cartesian x-y-z motion mechanism that uses 4 stepper motors: two of them are used to move the extruder in x-axis and y-axis. One more is used to move the print bed up/down on z-axis and one more is used to extrude the filament through the hot end.
The Monoprice 300 Guider II is the same as the FlashForge Guider II just Monoprice branded.
The MP 300 Guider comes fully enclosed, something that is not unusual for a printer of this price. A transparent front door is used to provide access to the print bed. The front door has an open/close sensor that can pause the printing when the door is opened, preventing temperature fluctuations. On top of the printer, is placed a transparent lid that gives access to the hot end and the rest of the mechanisms that require maintenance.
Compared to its small sister, the 300 Guider II is able to print much bigger models being its maximum print volume 21 Liters (280 x 250 x 300 mm). This printer also comes with a heated printing bed in order to print more advanced materials like ABS or PETG.
The filament is held on the spool holder on the back of the printer located on the back panel. In comparison to the Monoprice 150 Inventor II, this printer does not limit the spool size to 0.5 Kg which is really convenient as many brands sell 1kg spool size. The filament is driven through the run-out filament sensor to the direct extruder system.
The MP 300 Guider II interface is user-friendly and very simple to use. Monoprice has removed the physical button to navigate through the different menus and options. Instead, a touchscreen located on the top takes its place to navigate through the printing interface.
The print can be run from three different sources: Internal memory of 8GB, USB or Wi-Fi connection. The Wi-Fi option is very reliable and smart as it stores the file on the internal memory to ensure no information is lost. The printing files are generated by MP FlashPrint slicing software mainly but you can use Cura and other slicer softwares too.
The MP 300 has plenty of special features. The most notorious is the sturdy and enclosed frame that provides a completely controlled environment for the printer, free from dust, moisture, and debris in the air. The door sensor also makes sure that the printer is always operating safely and stable as it stops the print when the front door is opened.
Monoprice has included a run-out filament sensor essential to not waste any filament and print. The print will pause and wait until the new filament is loaded again. Besides that, the interface includes a very helpful unloading/loading function that will preheat the nozzle to remove/insert the filament from the extruder.
The printer will not only auto resume in the exact position after a filament run-out pause. It will also resume to the exact position after a power interruption. This, definitely, will ensure that the print will be completed!
Although it is a standard feature for most of the printers, it is important to mention that Monoprice 300 comes with a heated printing bed. This was not featured on the Monoprice 150 which was only able to print PLA filament.
MP 300 also includes 8GB of internal memory that allows the user to load the next print remotely or store it and print it whenever they wish.
Regarding the print performance, we can say that the Guider II is perfect in terms of consistency and reliability. The minimum printing layer of 50 microns helps to achieve clean and smooth surfaces. However, quality results are not the strongest point of this printer even though its price is high.
If you are a beginner user or you are willing to buy an educational and big print volume 3D printer, this is a perfect match for you as it includes tons of extra features. However, if you are looking for high performance and high quality prints, there are many printers out in the market that can match MP 300’s price and get you better results. Especially for tinkerers users, to whom high precision matters more than reliability or consistency.
In out opinion the high price of this printer decreases its value since its little sister, the MP 150 is less than one fifth of the cost and the only main difference is the printing volume and the heated print bed.
