Alfawise U20 Review: A Large Scale Budget 3D Printer

Alfawise U20 Review: A Large Scale Budget 3D Printer

This
printer ships in a huge box. Most of the frame is already
pre-assembled, making the big box a necessity. All of the pieces are
packed neatly inside styrofoam. In addition to the printer itself,
Alfawise throws in a few extra goodies. They make sure everyone is ready
to go with an assortment of 3D printing tools and a roll of PLA
filament.

In the box



  • 3D Printer components: Bed, frame, main box with touch screen

  • Additional tools: metal scraper, wire cutters, zip ties, hex keys

  • Micro SD card with a USB card reader

  • Sample filament: Yellow PLA

  • Filament spool holder

Assembly and setup

The
assembly instructions provided may be out of date. I had much more
success looking online for recent Alfawise U20 assembly videos. The
frame is held together with a few screws. It's possible to put the
machine together alone, but it's easier if you have an extra person to
help hold the frame in place.


There are a few labeled cables that need to be plugged in. I highly
suggest laminating the labels with tape as they fall off very easily.


The firmware needs to be updated immediately after assembly. It’s
worth noting, I ran into some issues with this. There’s a support group
on Facebook run by Alfawise with other users who had the same problem.
On occasion, the SD card provided by Alfawise won't allow the firmware
update to install. The group suggested I format a different SD card to
get the firmware to update correctly. This resolved the issue for me and
I haven’t had any more problems since the update. You can still use the
original SD card after the update.


Total assembly time: ~20 minutes

Design


Design 

 

The
overall design of this printer is well thought out. It's very easy to
change the filament, there's no extra bulk to the design, and the frame
is incredibly durable.


Build quality


The printer is built with very clean, high quality aluminum alloy.
The frame is finished with a shiny red coat and also features black
matte railings for the motion system.


Motion system


The motion system is constructed with high standard v-slot wheels. The result is clean movement with very smooth prints.


Bed features


The bed has some of the most exciting benefits. The Alfawise U20
comes with a heated glass bed right out of the box. The build space is
huge and maintains a consistent temperature throughout the entire bed
surface. On top of the glass bed is a custom adhesion plate. It's more
than capable of withstanding the heat and helps your filament stick when
creating a base layer.


The bed is pre-assembled with huge knobs for leveling. Coupled with
the leveling feature in the printer settings, the bed is very easy to
adjust.


Bowden extruder


The Alfawise U20 features a bowden extruder system. The filament is
fed into the printer away from the extruder head where it travels down a
tube before feeding into the nozzle. The benefits of this design allow
for speedy prints with less wobbling on your final print.


Safety features


Once you've finished printing your piece, the Alfawise U20 will
remove the nozzle from your final print and immediately start cooling.
The temperature will need to be manually set for your next print.

PrintingPrinting


Printing
on the Alfawise U20 is an exciting experience. It's easily one of the
most efficient printers on the market today. From the print quality to
the volume capacity, this is one of the coolest 3D printers I've had a
chance to experience first hand (especially in this price range).


Print quality

The
printer includes a .4mm nozzle and it supports 1.75mm filament. The
result is seriously fine print quality and really awesome prints. As
with any printer, it can be a little tricky and take some time to dial
in the best settings.

The
bed is huge! The exact build space dimensions are 300mm x 300mm x
400mm. This printer is more than ready for some large scale printing
projects.

The
Alfawise U20 comes with a touch screen interface. The box is large
enough to support the power supply and motherboard. It features a small
LCD screen to adjust the printer settings. There could be a few
improvements to the English translation, however.

Filament types

In
order to create printable files, you'll need slicing software. Free
software works fine. I was able to complete these projects using Cura.
The Alfawise website offers the possibility to get the last update

Loading
print files into the printer is incredibly easy. Just drop the gcode
files onto the Micro SD card and pop the SD card into the printer.
You're ready to print!

Conclusion

This
device is one of the most versatile when it comes to filament
compatibility. The official spec list features several different kinds
of filament. The Alfawise U20 can use PLA, ABS, PVA, PP, TPU, and even
wood filled filament.

Conclusion

Overall,
this is a really capable printer. It's not the cheapest printer on the
market, but it's absolutely one of the most affordable. There are a few
small tweaks that can be improved on the software side.


Otherwise, you'll find some of the best features around for 3D
printers: a heated glass bed, simple assembly, and incredible print
quality.
