CoreXY 3D Printer Designs On Thingiverse

While there are many open source 3d printer designs to pick from on Thingiverse. And when it comes to corexy printer designs there are a few that raise the bar. Here are some of the best designs that we would like to talk about.

What To Look For In a CoreXY Design

When you think about a good machine build you have to consider a few things. How developed is the design? Many common designs will have:

  • Contributors designing fixes, mods and other spun off remixes.
  • How many mods are there that could allow you to modify your printer for custom applications
  • Is there a user group that you use as a resource to troubleshoot or upgrade and update your build. While there are many resources to draw upon User groups will keep you in the circle of news, updates and creative solutions.

HyperCube Evolution CoreXY

HyperCube Evolution

The Hypercube Evolution is one of the main Core-XY designs you’ll find on Thingiverse. The User groups are huge and active. There are a number of mods and add-ons that allow you to upgrade your printer.

The HyperCube Evolution also known as H.E.V.O is a CoreXY printer designed by Scott 3D and inspired by the original HyperCube 3D Printer by Tech2C. Scott liked the belt arrangement on the Hypercube compared to other core-xy 3d printers and designed his own remix to further develop the corexy design to reduce the number of printed parts and simplify the build.

Design goals for the HyperCube Evolution 3D Printer:

  1. Increase the stiffness of the printer to further improve / reduce vibration artefacts.
    • 3030 extrusion used for the frame
    • 2020 extrusion used for the build platform frame
    • 8mm diameter X rails
    • 10mm diameter Y rails
    • 12mm diameter Z rails
  2. Minimise the size of the printer for the chosen build volume.
    • Parametric CAD design in Autodesk Inventor
    • Excel spreadsheet provided to allow for customised printer size

The prototype printer, with a build volume of 300 x 300 x 300, met with all expectation but did show some small bed vibrations when printing at high speed due to the large bed and counter levered design. Therefore, two build options are available. Hypercube On Thingiverse

D-Bot CoxeXY

Another common design that follows the HyperCube Evolution’s stats is the D-Bot. This is a more heavy duty design even uses 20mmx40mm extrusions. It’s a elegant mechanical configuration that also has a large active community of users who love to update and upgrade their machine build. The Dbot design is a spin off of the C-Bot. They’re very similar but the differences are:

1) Z-Axis lead screws and motors are repositioned to the front to aid lifting the print bed from its center of gravity rather than use a fully cantilevered print bed.
2) Increased printable Z height to 330mm (~13″)
3) 20mm rails
4) Reinforced printed parts to add regidity where needed or to minimize plastic.
5) Spool holder a cable chain accessories.
6) Relocated endstop mounting to maximize Y travel and utilize default homing scheme.
7) Overall reduction in cost compared to the original bill of materials (2$ square nuts vs 40$ Tnuts, etc.)

C-Bot 3D Printer Design

C-Bot 3D Printer

The C-Bot is a core XY printer design that utilizes open builds V-Slot rails.
It was designed by Carl Feniak with a couple goals in mind:

  • To eliminate use of linear rod/bearings and I use V-slot for all guided motion
  • To use two offset parallel belt runs instead of crossing belts as found in most core XY printers
  • To run the belts through the extrusion when possible for a cleaner end product
  • Make the entire setup easily modifiable and adaptable so others can use it for alternate bed sizes

Railcore CoreXY 3D Printer

Railcore ll

Next let’s look at the Railcore design. Developed by J. Steve White & Tony Akens of RailCore Labs and produced by Project R3D. This core xy design has some kick. Although this a new open source build has a strong and active community. It is a well thought out design that has verity of CNC machined upgrades to pimp your printer. The prints that are made from the machine are absolutely beautiful. This 3d printer build is most commonly found using the Duet Wifi to power the system. The pros of the Railcore corexy is:

  • Linear Rails on X,Y and Z-axis
  • Enclosure
  • 15mm extrusions to reduce the price of BOM
  • CNC machined upgrade parts
  • Space & Cost efficient
  • Flexibility and scalabiltiy in the design

The Railcore printer’s ecosystem of parts also include a variety of CNC machined aluminum parts that can be found by 713Maker and Mandala Rose Works that can make your printer look like a hotrod.

forkLIFT CoreXY 3D Printer Design on Thingiverse

forkLIFT CoreXY 3D Printer Design on Thingiverse

The forkLIFT was designed and published on Thingiverse by brunofporto and Token47. The design concept is:

  • Be a platform for multi-tool development
  • Easy to print – no supports needed! No aggressive overhangs or bridges!
  • Components designed as best as possible to avoid fatigue and weakness due to layer adhesion.
  • The parts should be resilient to common printing errors like too smashed first layers, etc. If not net me know!
  • All motors outside the printer chamber! This render a free access from the front and no issues with chamber heating the motors.
  • Belt tension at motor mounts. Easy to adjust and not prone to loose adjustment due to vibration.
  • Very versatile X carriage! Just swap the “Plates 42” to whatever you want, from your legacy printer head to lasers! Also designed with tool changing in mind.
  • Maintainability! All axis, bearings, etc. removable without touching the belts! All screws accessible.
  • Easy to close the printer as components have a good clearance from the outer plane of the frame. Even with 3030R extrusions!
  • Simple Z alignment: integrated parts!
  • Good looking! (This is open to debate 😀 )
