Monoprice Delta Mini V2 looks unusual for a 3D printer, but something about it feels familiar. We reviewed the original Monoprice Mini Delta a while back when it was a low-cost, though flawed, way to get started with 3D printing.
Are those flaws, such as unreliable USB connections and printing modes, addressed in the latest version? Despite a much-improved design, the Monoprice Delta Mini V2 3D printer’s software remains a weak spot.

Monoprice Delta Mini V2 3D printer review: Design
Incredibly small and compact, the Monoprice Delta Mini V2 printer measures just 14.5 inches tall. In contrast to most 3D printers that use a series of rails to guide the print head, the Delta 2 uses three arms, each connected to a separate print head. When one of these legs is raised, the print head moves in that direction. Monoprice Delta Mini V2 is able to move its print head up to anywhere on its print surface by coordinating all three legs.
There is one problem, though: the print area is circular and smaller than other printers of the same size. The print area measures just over 4.3 inches in diameter and just over 4.7 inches in height for the Mini Delta 2. In total, that’s about 81 cubic inches, a bit smaller than the 107 cubic inches provided by the Polaroid Play smart.
Delta Mini V2 has a microSD card slot, a Micro USB port, and a Wi-Fi interface, which can be used to connect to the outside world. However, with the latter option, you can’t use a web interface to control the printer or upload files directly to it using a slicing app. WiFi only works through an app that is rather poor.
Monoprice Delta Mini V2 3D printer review: Controls
It’s possible to use the Delta Mini V2 with an on-screen display, a slicer app, or the PoloPrint Pro app.
It comes with a small touch screen that can be operated with a fingertip or with a plastic stylus included. In addition, the on-screen keyboard makes it easier to enter precise information, such as Wi-Fi passwords. Touching the start button with your fingertip is fine for simple tasks, however.
Those of you who are interested can try the pre-release version of PoloPrint Pro, which is available on iOS and Android. The software isn’t as polished as it could be. I found that it failed to work or crashed often. Although there was no camera in this low-cost printer, I was able to monitor the print progress when it worked. I can also print from a micro SD card and from the online library. We asked Monoprice whether this would be added at a later date; they said it might be added in the future.
Using a slicing app such as Cura is the best way to set up a print. The Monoprice Delta Mini V2 comes with a microSD card that includes a customized version of this open-source program for Windows and Mac, and that’s what we used to print in our tests. WiFi connectivity is not supported, but it supports USB or saving print files to a microSD card. To print from Cura, you must use a USB or microSD.
Monoprice Delta Mini V2 3D printer review: Print process
This printer is quite simple to use. After you’ve created your print file in Cura or another program, you select the file in the on-screen menu and then press the print button to start printing.
With Delta Mini, the first thing it does is level the print bed by touching it three times to the bed to press a switch underneath. Using that information, the printer can lay down an even first layer by knowing where the print bed is. The Delta Mini lays down the first layer of the print on a heated bed before moving onto another layer.
No major errors were encountered during printing, with few errors. Usually, I had to scrape the print off of the print bed with a paint scraper after the final print stuck to the bed.
There are multiple types of filaments compatible with the Delta Mini V2, including PLA, ABS, and PETG. Monprice’s 3D printer can use 1.75mm filament from any manufacturer, so you’re not limited to one brand of filament. Both PLA and ABS were tested on the Delta Mini, and both produced excellent results.
In terms of temperature, you’ll be limited by the maximum print head temperature and the maximum print bed temperature (250°C and 100°C respectively). A Delta Mini V2 printer can’t print on flexible materials due to the type of print head that these materials require.
Monoprice Delta Mini V2 3D printer review: Print speed
When running in draft mode, the Delta Mini V2 printed a 3.5-inch high Thinker figure in about 3.5 hours, using a layer height of 0.2 mm. I found that the 3D printer runs a lot slower at normal quality, resulting in a 7 hour and 10-minute print. By using this mode, each layer is half as tall.
Monoprice Delta Mini V2 3D printer review: Print quality
To test 3D printers, we use several models, including Rodin’s Thinker statue, a gear set, and a geometric sculpture. Because the Delta Mini 2 prints with excellent detail, I was impressed with the quality of them.
I was very pleased with the result of our Thinker test print; it had smooth, natural shoulders and good details on his face. However, there was some layering both in the normal and draft modes.
We used the same gears test model and it worked very well since all we had to do to fit the gears together was to remove them from the raft. It was not necessary to do any other trimming, cutting, or tweaking to get a set of gears that turned smoothly and evenly.
We use the geometric sculpture in our testing because it is hard to print. It requires the ability to precisely control the flow of the molten filament since lots of angles and sharp edges must be printed. As a result, the Delta Mini V2 produced sharp, well-defined edge and point definitions. After trimming off the support material used to hold the print during the printing process, we had a very well-printed sculpture with spikes.
|Prints PLA, ABS, PETG, and other materials||Can’t work with flexible materials|
|Low cost, fully-featured 3D printer||Prints are limited to 4.3 inches in diameter|
|Excellent print quality for the price||The software has some rough edges|
This printer does a good job despite its simplicity. With this printer, you can print quickly and in excellent quality. It also works with many different materials. As long as the print bed is 4.3 inches wide and 4.7 inches high, it won’t be able to print anything wider or taller than that. At its price, though, the Delta Mini V2 is an excellent value.
It’s still difficult to find a more affordable printer with these mobile software issues. This da Vinci Nano from XYZprinting costs around $200, but it’s becoming increasingly difficult to find. It is therefore wise for beginners to give 3D printing a try with an inexpensive option such as the Monoprice Delta Mini V2.
