Voron 3D printers are known for being well engineered for high-speed 3D printing, making no sacrifices in order to achieve speeds around 100mm/s for regular printing moves. With a little tweaking and tuning you'll find that you too can get your LDO Voron 2.4 R2 kit to speed through 3D prints with ease.

Here are the key features of the LDO Voron 2.4 R2 3D Printer DIY Kit:

  • Large-Format
  • Linear Rails on Every Axis
  • Parts by Trusted Manufacturer LDO
  • Stable Build Plate for Quick Printing
  • Powerful Bed Heater
  • Easily Enclosable

With a huge build volume of up to 350mm x 350mm x 350mm, the Voron 2.4 has one of the largest build volumes available at MatterHackers. Reduce the number of models you need to split into separate pieces to fit within your build plate! Or if you have one small design and need hundreds of them, 3D print huge batches on the super-flat milled aluminum build plate.

  • Build Volume:
    • Voron 2.4 350: 350mm x 350mm x 350mm (13.8" x 13.8" x 13.8")
    • Voron 2.4 300: 300mm x 300mm x 300mm (11.8" x 11.8" x 11.8")
  • Prototype or create large end-use parts in-house

Stainless Steel Linear Rails from the LDO kit on a fully assembled Voron 2.4 3D Printer


The most common 3D printers use bearings and linear rods, an affordable and simple design that allows for a little play in the system, as these machines aren't intended to move fast. Once you approach speeds near 100mm/s, that play burdens the possible results you could hope to achieve. Linear rails are significantly more constrained and with the properly chosen pre-load prevent the various carriages from vibrating and wobbling throughout motion.

  • 7 Stainless Steel Linear Rails
    • Four guide the Z axis
    • Two guide the Y axis
    • One guides the X axis


In order to 3D print at high speeds, you need a 3D printer that's as rigid as possible to limit any resonant frequencies. Many common 3D printers have a bed that constantly moves along Y or regularly moves along Z, but the Voron 2.4 has a bed that doesn't move at all; it is rigidly mounted to the frame. By utilizing a "Flying Gantry" style motion system, the 3D print is able to be locked down to the build plate throughout the 3D print without any fears of a wobbling cantilevered bed or the inertial mass that would need to be considered.

  • Milled MIC6 Aluminum build plate is 6mm thick to ensure plenty of thermal mass to soak heat and remain flat throughout heatup cycles.
  • Magnetic sticker can remained magnetized at temperatures necessary for ABS 3D printing temperatures
  • Double sided, flexible spring-steel build plate allows you to easily switch between smooth or textured PEI to improve part adhesion and flex and twist the build plate to remove finished 3D prints.

By carefully using the power of mains voltage, the silicone heater mat is able to reach temperatures as high as 110°C within a couple minutes. By connecting the included thermal fuse, risk of thermal runaway is mitigated, as an overheating bed will cause the fuse to burst and disconnect power to the bed heater.

  • 120VAC 750W silicone bed heater
  • Adheres to the underside of the MIC6 aluminum build plate.
  • Thermal fuse bursts at 125°C for thermal runaway protection
  • Grounding wire protects the user from faulty wiring.


This Voron 2.4 Kit is assembled by LDO Motors, an industry leader known amongst the additive manufacturing community for producing and supplying quality 3D printer components and accessories. Sourcing trusted reliable parts is half the battle of successfully building a Voron and LDO makes it a whole lot easier by manufacturing and sourcing a large majority of those essential parts so you can focus on the labor of assembly rather than component hunting. 

  • Sourced and Manufactured by LDO
  • Greatly Relieves User's Burden for Sourcing Parts
  • Rest easy knowing components are from a trusted supplier

The entirety of the Voron 2.4's construction remains within the space of the frame; not a single part leaves the volume created by the frame. This makes enclosing the 3D printer simple and easy as you can easily mount panels using the T-slot frame. Included with this kit are all the clear acrylic panels you need to enclose the build volume and have a magnetically latching set of front doors. Before you 3D print the panel clips and begin enclosing the printer, make sure all the components are able to withstand the higher temperatures that will be generated; enclosing the build volume is for ABS and aluminum parts kits only, but panels are included with all kits.

  • Fully enclosable by design
  • Keeps drafts out and hot air around temperature sensitive parts
  • Contains any possible fumes that can be vented through the included exhaust fan assembly.


Originally intended as a passion project, the Voron 2.4's explosion in popularity showed the difficulty in creating this as a self-sourced project. Thanks to the work of many interested parties, it's easier than ever to get a ready-packed kit with all the components you need to assemble a working Voron 2.4. With such an interested following comes many modifications and quality-of-life upgrades offered by the community to improve your experience with the Voron 2.4, all of which are compatible with this kit.

  • Blind joint aluminum frame
  • Fasteners Kit with all the necessary nuts and bolts
  • Electronics and Wiring included from motors to sensors
  • Panels Kit for the electronics compartment and the sidewalls
