Choosing a Printer / Extruder

This is a guide to help people in selecting and building their first Voron printer and/or extruder.

Printer Models

There are currently 5 printers in the Voron lineup. One is not necessarily better than the other, just different. All printers (except Legacy) are capable of being fully enclosed to print ABS but can just as easily print PLA, PETG, or even Nylon. All printers in the Voron lineup are designed to use a Raspberry Pi linked to one or more motor controller board(s) to manage all of the printer functions and interface controls.

Note: Pricing estimates are in US Dollars and do not include any necessary tools or other common building supplies. Costs vary widely depending on sourcing, part selection, and shipping costs.

Voron 0

The Voron V0 is a traditional CoreXY design with the bed moving along the Z axis. It is a tiny 120mm^3 print area built with 1515 extrusions. It encloses naturally so printing ABS is possible. Currently, all single mechanical parts for V1 and V2 can be printed on a V0 bed. The design accounts for stock Makerbeam XL extrusion lengths (which come tapped) and standard MGN7 linear rail lengths, so scaling the design will start to increase cost or labor involved with tapping. The bed is also cantilevered which will also restrict scaling. This printer can be built for between $400 - $600.

Voron 1

The Voron V1 is a traditional CoreXY design where the bed moves along the Z axis. It is simpler to build compared to V2 and can be built for between $1,000 - $1,300. It encloses naturally so ABS or other temperature sensitive filaments can be printed easily. It uses rails for the X and Y axis. Standard sizes range from a 250x250 plate or a 300x300 plate. Z height is somewhat restrictive due to the limited options with integrated lead screw steppers, maxing out at 230mm.

V1.8 Homing Routine

Voron 2

The Voron V2 is a modified CoreXY design with a static bed and a gantry that moves along the Z axis. It is a much more complex build because it includes things such as 4-point gantry tramming to align to the print surface, dual MCUs, and other unique features. It is also designed to be fully enclosed so it prints ABS or similar filaments very well. Due to the linear rails the design is scalable in stock form from 250^3 and 300^3 all the way up to 350^3. More linear rails, larger print surface, and other V2-specific items make this printer more expensive, at between $1,500 - $1,900.

V2.4 Quad Level


The Switchwire is a Voron take on a classic Mendel (aka “bedflinger”) design. It is a CoreXZ design so the print head is belt driven in both the X and Z axis eliminating the typical leadscrew Z drive allowing for very fast Z movement speeds and less weight on the grantry by moving the X motor to the frame. The stiff 3030/3060 contructed frame is just large enough to cover the entire swing of the Prusa 250x210 bed and allows for a natural enclosure. Without having an existing Prusa printer to pull parts from, cost is between $700 - $900

The Legacy is a tribute to the roots of the Voron project and the RepRap project. It returns to the classic design using LM8UU rods and bearings in the 230^3 size but retains the new Afterburner toolhead. It is not designed to be enclosed. The electronics enclosure is very small, adding to the open-air vibe. Costs are variable depending on the builder’s old stock of LM8UU components but are expected to be between $600 - $800.

Extruders and Variants

Mobius (M4)

Mobius is the original Bowden extruder for Voron printers, designed to be mounted on the frame. Highly optimized, dual gear, and very effective for Bowden setups. Driven by a full-size or a compact “pancake” NEMA17 motor.

M4 Introduction Video


Jetpack is a modified Mobius designed to be mounted on the X axis for a shorter Bowden. Was designed as an intermediary solution to reduce the bowden tube lengths before the introduction of Afterburner and has been superceded by the M4. It is driven by a compact “pancake” NEMA17 motor.


Afterburner is not specifically an extruder, but the collective name for the Voron direct-drive interchangeable toolhead system.

Afterburner Announcement Video


Clockwork is the name given to the original extruder system for Afterburner. It is a repackaged BMG dual-gear extruder driven by a compact “pancake” NEMA17 motor. The Afterburner term is commonly used to refer to this extruder.


Pocketwatch is the Afterburner Clockwork repackaged for the smaller size needed by the V0 printer.


Galileo is the newest extruder designed to fit on an Afterburner toolhead. It is based on the Orbiter extruder and incorporates a planetary gear reduction to allow a smaller housing size and even smaller motor to be used in order to reduce weight.
