Alfawise U20 3D Printer: build volume

First, the Alfawise U20, just like its predecessor, is a large scale printer — but not quite as large as its predecessor. The Alfawise U10 came with a gigantic 400 x 400 x 500mm build volume, but the new model features a more modest 300 x 300 x 400mm engraving area, which makes it more fitting for the desktop 3D printer category.

Alfawise U20 3D Printer: build quality

The printer comes with a 0.4mm diameter nozzle and uses a Bowden-type extruder enabling higher printing speeds (20 - 150mm/s). The frame is made with super durable aluminum alloy — steady, stable and wear-resistant. There is a high-power heating bed for an efficient printing session and an 2.8 inch full colour touch screen for quick and easy navigation.

The Alfawise U20 supports offline SD card printing and is equipped with a USB port for connecting to other gadgets: laptops, smartphones, tablets, etc. The printer supports a standard set of filaments: you can use ABS, PLA, TPU and carbon fiber materials for your creative projects.

Alfawise U20 3D Printer: assembly

Just like the previous model, the Alfawise U20 comes with two main components: the printer frame and the separate control box. The printer comes semi-assembled and this means that you will not need more than five minutes to put the whole construction together.

There is a very detailed manual coming together with the printer with clear step-by-step instructions. If you prefer to have some interactive guidance during the assembly process, consider watching one of the many U10 assembly tutorials available online — the processes do not differ significantly for the two models.

Alfawise U20 3D Printer: extra features

What makes the Alfawise U20 stand out among other desktop 3D printers in the same price category are a few extra features that can prove to be very helpful in your printing process.

● Filament Run-Out Protection: if you ever run out of filament in the middle of your printing project, the filament run-out protection feature will make sure your work does not get messed up. The Alfawise U20 comes equipped with a sensor, which will timely detect that you are running out of filament and pause the printing process.

●​ Resume Printing Function: this feature will save the day in case of a power failure: your printer's electrical connection is suddenly interrupted, there will be no damage to the printing process. The resume printing function is typically found in the more expensive models (like the famous Original Prusa i3 MK3) — and it is impressive to see it on a budget 3D printer like the Alfawise 3D.

Alfawise U20 3D Printer: summing things up

The Alfawise U20, just like the model before it, is a strong contender for the best budget desktop 3D printer — and not only due to its very decent build quality and a relatively large engraving area. The extra functionality that the printer offers, namely the Filament Run-Out Protection and the Resume Printing Function are great additions to the mix and will be especially appreciated by amateur creators who want extra safety and guidance for their creative projects.

Coming at a very reasonable price - $299.99, the Alfawise U20 3D printer is a great choice for maker, creators and DIYers and can also be a great asset used in education process. The best thing: you get to try and explore the latest in 3D printing technology right in the comfort of your home, office or studio and without breaking the bank!
