The heated bed that comes with the Tronxy X3S is an impressive 330mm x 330mm. It is an aluminum bed with PCB traces on the bottom side like most common heated beds that come with other 3D printers.

It struggles to get past 40°C. This won’t matter if you are just printing PETG and PLA. It also comes with a poly-carbonate sheet and a BuildTak like build surface. We decided to print directly on to the poly-carbonate sheet and we haven’t gone back. The prints stick well, even at a good distance away from the poly-carbonate sheet. You can remove it and flex the poly-carbonate sheet to help release the model.

All of the electronics are housed in an acrylic box beside the printer which I showed off in my update video on the printer. This does make the printer look extremely neat but it does mean the the printer takes up a lot more space. There is an upgrade I highly recommend that gives the printer legs allowing you to fit this control box underneath the printer. The control box does feature an LCD screen so you can print directly from a micro SD card or hook it up through USB to you computer for tethered printing. With its large build size you can definitely print a huge variety of things on this machine and its open form factor allows for trouble shooting as well as easy viewing on your print progress.

Spool Holder

Yes, this printer comes with a spool holder. It is only suitable for spools that have a large center
hole (45mm or larger). We have fixed this by cutting off the part that limits the spool from sliding on and making a friction fit cap to hold the spool on. However, if you have spools with a smaller hole than 45mm, you still need to figure out some other way to hold those spools.

Melzi Controller

The Melzi controller included with this printer kit is a CXY-v.2-0508. A modified version of a Melzi 2.0 which is a clone, of sorts, of a Sanguilolu 3D Printer controller. The CXY-v2 board powered by the ATMEGA1284P microcontroller and includes 4 stepper drivers. The CXY-v.2-0508 supports only one extruder. Stepper drivers included on the chip are either A4982 or A4988.


20×20 Extruded Aluminum frame

Electronics Enclosure with fused power switch and excellent wire management

It comes assembled out of the box which makes for quick and easy setup. 1 hour or less.

Spool holder included

Strong 3D printer

Fast and accurate

Large print area


The power supply is small for this unit.

Upgrading to 30 amps power supply, you will see a significant speed in the printing.

Stock controller board only supports one extruder.

Stock firmware can be a bit flaky, and some settings may be wrong.

Firmware may need to be upgraded for better use

Spool holder doesn’t support spools with an inside hole diameter of less than 45mm.


The printer is not a bad printer. It has a lot of potential and for what you get it’s a good buy. Other Reviews on this printer suggest that this printer can hold it’s own compared to other 3D printers. Use of this printer can be done in schools to teach children. Please review other post called “3D printers in schools”

Pretty quiet and very solid. The touch screen has one-touch filament loading and unloading that works very well. Much info is displayed, including the time to finish and time elapsed. Very easy level bed and beginner friendly. Beginners and intermediate can get a lot of use out of this 3D printer because of the ease of use.
