Despite its unusual design, the Monoprice Delta Mini V2 feels familiar. Our review of the original Monoprice Mini Delta appeared a while back when it was an inexpensive way to get started with 3D printing.

How does the new version address those flaws, such as printing issues and unreliable USB connections? Although the Monoprice Delta Mini V2 3D printer’s design has been greatly improved, its software still has a number of faults.

Monoprice Delta Mini V2 3D printer review: Design

3d printer

Monoprice Delta Mini V2 printers can fit into a space as small as 14.5 inches tall, making them extremely compact.  Delta 2 utilizes three arms, each linked to a separate printhead, as opposed to most 3D printers that rely on a series of rails to support the head while printing. A raised leg will move the print head in that direction. In order to move its print head, Monoprice Delta Mini V2 coordinates the movement of its three legs.

However, the print area is circular and smaller than those of comparable printers. With the Mini Delta 2, the printing area is over 4.3 inches in diameter and over 4.7 inches high. The Polaroid Play smart provides an area of about 107 cubic inches, slightly less than 81 cubic inches.

With the Delta Mini V2, you can connect to the outside world via a microSD card slot, Micro USB port, and Wi-Fi interface. Using an app to slice your files directly into the printer is not possible with the latter option. Using WiFi requires an app that is rather poor.

Monoprice Delta Mini V2 3D printer review: Controls

PoloPrint Pro is an app that can be used with an on-screen display, slicer apps, or the Delta Mini V2.

An included plastic stylus or a fingertip can be used to operate the small touch screen. Furthermore, the on-screen keyboard allows for more precise data entry, such as Wi-Fi passwords. When you’re performing simple tasks, however, touching the start button can be done.

It is available on Android and iOS. If you are interested in trying the pre-release version, you can download it here. This isn’t the most polished of programs. Several times, I was unable to run it. While this low-cost printer did not have a camera, I was still able to monitor the progress of the print job. Additionally, I can print from a micro SD card and the online library. Monoprice stated they would consider adding this later.

The easiest way to set up a print is to use a slicing app such as Cura. In our testing, we used a customized version of this open-source program on the microSD card included with the Monoprice Delta Mini V2. Neither Wi-Fi nor microSD cards are supported, but USB or microSD card printing is supported. The USB or microSD must be used to print from Cura.

Monoprice Delta Mini V2 3D printer review: Print process

The printer is quite easy to use. As soon as you have created your print file in Cura or another program, you select it on the screen and then press Print to begin printing.

To level the print bed, the first thing Delta Mini does is touch the surface three times to a switch underneath three times. By knowing the location of the print bed, the printer can lay down a first layer that is flat. Using a heated bed, the Delta Mini prints the first layer before moving on to the next.

The printing process was error-free, with only a few minor issues. My usual method of removing paint from the print bed after it had been printed was to scrape it with a paint scraper.

Delta Mini V2 can print with various types of filaments, including PLA, ABS, and PETG. As such, you’re not restricted to just one brand of filament with the Monprice 3D printer that uses 1.75mm filament. The Delta Mini was tested on both PLA and ABS. Both materials yielded excellent results.

There is a temperature limit of 250 °C on the print head and 100 °C on the print bed. Since flexible materials require a different type of print head, a Delta Mini V2 printer cannot print on them.

Monoprice Delta Mini V2 3D printer review: Print speed

Using a layer height of 0.2 mm, a 3.5-inch high Thinker figure ran on the Delta Mini V2 in about 3.5 hours. It took me 7 hours and 10 minutes to print my model at normal quality, which was a lot slower than I had expected. The layers are half as tall in this mode.

Monoprice Delta Mini V2 3D printer review: Print quality

A gear set, a geometric sculpture, and Rodin’s Thinker statue are the models we use to test 3D printers. I was impressed with the quality of the Delta Mini 2 prints because they print with great detail.

My test print of Thinker was very pleased; its shoulders looked smooth and natural, and his face was highly detailed. It did however have some layering in both draft and normal mode.

Using the same gears test model, we were able to fit the gears together very easily because we only needed to remove them from the raft. Getting gears that turn smoothly and evenly did not require any trimming, cutting, or tweaking.

Due to its difficulty in printing, we use geometric sculptures in our testing. As there are lots of angles and sharp corners to be printed, it demands the ability to precisely control the flow of molten filament. Due to this, the Delta Mini V2 produced well-defined edge and point definitions. We had a very well-printed sculpture with spikes after removing the support material used during the printing process.

Pros Cons
Prints PLA, ABS, PETG, and other materials Can’t handle flexible materials
Low cost, fully-featured 3D printer Prints are limited to 4.3 inches in diameter
The print quality is excellent for the price The software has some rough edges


Despite its simplicity, this printer does a good job. You can get excellent prints from it very quickly. Additionally, the printer can handle a wide range of materials. Unless the print bed is wider than 4.3 inches and higher than 4.7 inches, it can only print things 4.3 inches wide and 4.7 inches tall. Despite its price, the Delta Mini V2 is a great value.

Even with these mobile software issues, it’s still hard to find a more affordable printer.
