3d printing review

VZero – tiny DIY coreXY 3d printer from VoronDesign

I am a fan of Voron Design – this company is developing fantastic, open-source DIY 3d printers. It is not a lifetime vow. I am always curious about what is coming from Prusa, Creality, and a few other companies. However, now that I’ve got some years of experience in 3d printing, I believe I can detect the best machine for me. Today it is a Voron.

Here is what I like:

  • Performance
  • Just enough, no useless features and marketing tricks
  • DIY, which allows me to master all mechanical and hardware aspects and assure the maintenance
  • Made by savvy people with a taste for design
  • Cool community and mods
  • Printer updates

Voron Zero (aka Voron0 or VZero)

VZero is the 3rd Voron printer I built. I have already the Voron 2.4 – a high-performance CoreXY printer and the Voron Switchwire.

Voron Zero is very small. The build plate is just 12 x 12 cm and you may wonder why building a printer with such a small print volume. For my printing usage the advantages are clear:

  • this will make an excellent secondary printer for smaller parts
  • it is a high-speed, precision CoreXY machine
  • the design is simplified – no need for an ABL for example for this small bed
  • energy efficient printer – power consumption is only 150W

TBH, in the beginning, I thought I’ll use it occasionally as a backup machine. Truth is today it is my most used printer. It is just astonishing how many parts I was printing before on a 1KW machine, fit in the Voron0.

Voron0 is a beast for printing ABS, but also PolyMax PC.
Of course, it prints fine common filaments like PLA, PETG, and TPU.

Voron0 – hardware, software, sourcing

V0.1 is the first major update of the initial Voron0 3d printer. It adds a direct printhead (called Afterburner Mini) and a more stable Z-axis stepper motor with an integrated lead screw. The heated bed is now relying on a 24 V silicone heater (the initial version had mains supplied 110/220 V heater through a Solid State Relay). This simplifies a lot of the wiring, by eliminating the SSR.

The printer is light – less than 6 kg and portable. To achieve this many components are downsized compared to a traditional printer:

  • 1515 aluminum extrusions for the frame
  • NEMA14 steppers. Only the Z-stepper with integrated lead screw is a NEMA17
  • MGN07 linear rails
  • Small 150 W / 24 V power supply
All parts for Voron0 3d printer
Overview of all parts needed to build a Voron0. All components could be purchased in a kit, except the 3d printed parts. If you don’t have a printer capable of printing ABS, it is also possible to order the 3d printed parts from the Voron community or on Aliexpress

Control electronics are based on the small 32-bit SKR E3 mini V2 board combined with a Raspberry Pi running Klipper firmware. For a print server, you can choose between OctoPrint (my choice) or the newer Mainsail OS/Fluidd. All of them provide a web interface to control and monitor the print job over Ethernet/Wifi/Internet.

Sourcing the parts is relatively easy using the BOM configurator and sourcing guide provided by Voron Design. If you want to get the parts faster though, the best way is to buy them in a kit.
Here are some of the V0 kits available on Aliexpress:

Getting a kit is a huge time saver, however, you don’t have control over each component. For me the most important parts to look at are:

  • quality of the linear rails – Blurolls kit comes with genuine Hiwin rails;
  • quality of the motors – Blurolls wins again because it integrates the LDO motors kit for Voron0;
  • quality of the build platform – FYSETC states their aluminum plate is MIC-6;
  • is it the full kit? – Blurolls again, because they have the Voron0 display in the kit.
Here is my review of the Blurolls kit.
It also gives a nice overview of the build process.


The VZero is a great second printer – fast, reliable, and energy efficient. It handles all small parts up to 12x12x12 cm. If you enclose it, it excels in printing ABS and PolyMax PC.

The assembly is time-consuming (took me about 3 days). It requires fine-tuning the belts, in order to achieve equal belt tension. Once set up though, it delivers constant printing quality. At the time of writing, I was using it daily for 2 months without changing anything from the initial setup.
I haven’t needed to re-level the bed a second time – every first layer is still perfect.

Update Mar’22: This printer has proven its reliability. The only thing I changed for nearly 8 months of daily use is the Mini Afterburner. I replaced it with a bowden toolhead with a Voron M4 extruder, because the cable holder on the back broke 2 times.
