The increasing interest in 3D printing technology witnessed over the recent years has led to the manufacture of low-cost printers to cater for the budget buyers.

If you are just getting started on this new frontier, cheap 3D printers are the way to go! But before you make the investment you need to know what you can expect from it.
The Monoprice Mini Delta is a cheap 3D printer model that some have touted as the best selling printer in the world.

It is the ideal entry-level device to welcome you to the 3D printing experience, especially if your budget is relatively limited.
Today, we review the Mini Delta from Monoprice by analyzing it features and printing performance to demystify its “best-seller” claims.

However, we won’t leave out any weaknesses we come across.



The Mini Delta has a kind of odd-design. As expected, it is tiny, standing at only 15” tall and not more than 10” deep. It has an open build with a cylindrical shape.

It does a good job of maintaining a consistent temperature and will be great for printing small-to-medium size models.

The print head features three arms attached to a drive belt which is turned by a motor.

At the base of the Mini Delta are three motors that move each drive belt which in turn, move the arms.

The general simple construction of the printer offers a vast scope for modification, including expanding the build volume slightly.

Physically, the set up of the printer is quite straight forward. Just remove the foam and packaging then plug it in. There's an LCD screen, as well as controls that you use to load the filament.

The combination of an extruder and a heated print bed implies that the Delta can support both PLA and ABS materials.

The printer uses a 1.75mm filament without restrictions involving the manufacturer, so this leaves you with a lot of choices. This will include fairly new filaments like metal and wood!

During testing, I found that the printer is fairly fast for its class. It produced a 4-inch tall Thinker model in just three and a half hours in fast mode and just less than nine hours in normal print mode.

This is actually faster than rival budget printers like the da Vinci Jr Mix 2.0 which takes almost 5 hours in fast print mode. The Delta produces pretty decent prints, although they are not astounding. 

The Thinker model printed during testing had a smooth surface in both modes. Nevertheless, the fast mode experienced a few glitches, with bits of material not getting stuck to the next print layer.

The same results were visible on a geometric sculpture test. Although the edges were smooth, I could see lots of filament material hanging off.

I believe this was as a result of the print head moving from one side of the print to the other. Post-processing will easily get rid of these but the surface of the print will have visible layering.

What’s amazing about the Monoprice Delta Mini is that despite being one of the cheapest 3D printers in the market today, it still offers you a range of advanced features that aren’t common in under $1,000 printers.

The all-metal frame gives it a sturdy build that protects the printer during transportation. It has a heated build plate that aids in preventing warping, as well as an automatic bed leveling function.

You also get a maximum resolution at 50 microns on the Delta and a full-color LCD screen. This printer supports WiFi connectivity and is compatible with multiple printing materials.

You’d be lucky to find all these features stacked in a $1,000 printer! However, the most glaring weakness on the Delta should be its miniature build volume.

The build area is only 4.3 inches wide and 4.7 inches tall, which is extremely limiting to the kind or size of objects you can print.

The Monoprice Mini Delta costs around $160. And while there are a handful of under $100 printers currently under development, none is bound to hit the retail shelves anytime soon, with some showing little promise of ever selling in the market.

What’s even more impressive is that you can utilize any brand of filament on the Delta. In many cases, budget printer manufacturers confine you to a single proprietary filament, which is gladly not the case in this printer.

As a user, you have the luxury of experimenting with various filaments to find the ideal print models for you.

At around $190, the M3D Micro is a noteworthy rival, but it doesn’t come with the premium features you get on the Mini Delta such as WiFi connectivity and a heated bed.

You will be hard pressed to come across another printer that offers you so much for so little.

You can also take a look at some of the other 3D printers under $300 and see which one you suits you the most.


There are general FAQS on the Monoprice website that make good reference when troubleshooting information for a number of 3D printer problems.

Much of the knowledge provided will be instrumental in diagnosing the causes of issues you might be experiencing on your printer.

It’s also easy to correspond with experts if you need technical assistance. You can choose to email them, call them on the phone, or have a live chat.

Furthermore, you also get a 30-day money back guarantee and a one-year warranty when you purchase the device. This is quite impressive when you consider the cheap price tag on the Mini Delta.

The other advantage with this printer is given its popularity; there are numerous public forums you can join to access valuable information, in addition to what you get on their website. 


If you’ve just caught the 3D printing bug and are wondering what the technology has to offer, a price tag around $160 would be a nice place to get you started. 

I can’t see a better offer out there than the Monoprice Mini Delta. Despite its low cost, you still get a respectable 3D printer with decent printing capabilities.
