Circuit Specialists’ Robox Dual-Material Head Upgrade | 3D Printing

The date is September 20th, and Ben Hudson (CEL Robox Certified Technician) makes an appearance at the Circuit Specialists headquarters in Tempe, Arizona. The mission, upgrade Circuit Specialists’ Robox 3D printer by installing the revolutionary new dual-material head and second filament extruder.

Originally launched in 2014, the CEL Robox has quickly grown – and sustained – a reputation of being one of the greatest plug n’ play 3D printers of all time. In the 2016 “3D Printer Guide” by 3D Hubs it was named best in its class, and 100% of users surveyed said they would recommend the Robox to their friend.

Installing the dual-material kit is possible as a DIY project, however, Ben rates the task as “difficult” and most people will require 1.5 to 2.5 hours to successfully complete the upgrade. CEL also asks that all interested DIYers contact CEL and submit a service ticket before beginning the process, as a matter of preserving any applicable warranties.

Below, you’ll find the official video instructions provided by CEL.


From CEL: Installation of this kit should only be attempted at your own risk. If you are not able to perform this installation without damaging your hardware, please purchase an installation service from the Services menu. We recommend that you watch this series of videos before purchasing the product.


For those not interested in replacing the head themselves (like us for example), CEL offers a simple solution to getting your print head replaced.

As one of the few vendors with close access to support, Circuit Specialists includes factory upgrade services with the purchase of the dual-material kit. We will send a return label for your printer and ship it back to you, at no additional charge, once the Dual-Material Head and 2nd Extruder have been installed.

In most cases, Ben himself can be found elbows deep in Robox upgrades.

The entire process took somewhere between 45 minutes and an hour. We were nothing short of totally impressed with the efficiency of Ben’s skills, and the scope of his 3D printing knowledge.

Once the process was finished, we all took a moment to gawk at the results.

We couldn’t wait to see it in action! However, we still had to be patient while the Robox ran its calibration process.

While the Robox ran its calibration process, we had an opportunity to interview Ben for Episode 7 of CircuitTV!

Some photos of the first dual-material 3D prints we ran:

Each of these was printed using the “Woody Beach” and “Thermochrome (color changing)” specialty filaments. If you didn’t already, you can see the thermochrome go from purple to pink in CircuitTV Episode 7!

If you’re interested in seeing the dual-material head in action, here’s a 7 minute hyper-lapse of the Robox bearing print!

All-in-all, we’re very excited to have the ability to run dual-material prints on such an excellent 3D printer. As with all things 3D printed, the possibilities are endless, and with the high-quality support materials available, we predict the dual-material head will change the game forever!

Oh, and don’t forget, members of our Circuit Workbench also have access to the Robox!
