DIGGRO Alpha-3 High Precision 3D Printer

This 3D printer comes with a handy, touchscreen interface that makes working with it so much easier and rather enjoyable. It is very easy to scroll through and select files. User-friendliness was definitely high on the ‘must-have’ list for DIGGRO when making this product.


The thing with many 3D printers is that they make a heck of a lot of noise. With this one, though, the noise is noticeably reduced. Thanks to its design, you will also experience a much more accurate performance.

The system will let you know if the printer is running out of filament, which is a useful feature. You won’t be doing something while it’s printing to return to a half-finished project because you didn’t know you were out of filament.

In addition, should you experience a power failure for whatever reason, you won’t have lost your progress. The printer has a useful ‘Resume Print’ feature. The hot bed consists of aluminum substrate and other quality materials. They all work together to create an efficient printer.

It is able to work at a good, uniform temperature for the best results. However, sometimes the hot bed can malfunction and fail to heat. This could be ascribed to faulty design or manufacturing.

Very impressive software goes into running this 3D printer, and it makes a difference. The software influences how well the printer works, and how easy it is to use. Thanks to the open-source firmware, this printer keeps improving.

Users can create and share their additions to the printer. It is also possible to create your own add-ons if you have the savvy needed.

It should be noted that connecting the printer to a computer with a USB cable can be tricky. The printer seems to have difficulty with this type of connection.


  • Software is very impressive
  • Noise levels are greatly reduced
  • Progress won’t be lost in case of power failure
  • Made of high-quality materials
  • Impressive accuracy


  • Hot bed can malfunction and not heat up
  • Connecting with USB cables doesn’t always work

TRONXY New Upgraded 3D Printer XY-2 PRO

The XY-2 PRO is an improvement of a previous version and promises to be better and easier to use. This model has a much larger build volume than its predecessor and also comes with some new features. Plus, it has a very good frame design.


Although this 3D printer has many good features, it has a very ‘bare’ frame and design that many users appreciate. There is nothing excessive or extra that makes it cumbersome or heavy.

The performance of the TRONXY is very good and is admired by lovers of 3D printers. It is very easy to put together because it comes partially pre-assembled. It also features a touchscreen display that is very easy to use.

For its price, people will be happy to know that this 3D printer comes with an auto-leveling feature. That’s not common in the more affordable printers. You won’t have to spend time trying to level the bed by yourself, as this can be very tricky.

The operation of this printer isn’t as loud as some other printers tend to be. With that said, the fans can be a little loud.

The heat bed is also able to heat up very quickly, which is always a good thing. One thing that stands out in a negative way is that the manual and instructions aren’t great for beginners; there are terms and descriptions that can confuse anyone new to 3D printing.


  • Heated bed warms up quickly
  • Durable and attractive frame and design
  • Comes with auto-leveling feature
  • Touchscreen menu is easy to use
  • Assembly is fast

In the end, the printer you choose will depend on your unique needs and requirements.
