I have some exciting news about a new product that we have been working on

The Prometheus System!



DisTech Automation has developed a new solution for multi-filament 3D printing called The Prometheus System which allows you to print 2 different filaments from a single nozzle. It works by pulling one filament out of the hot end and feeding another filament into the same hot end to switch between filaments. This new product builds off of our existing Prometheus V2 Hot End.

Using a combination of custom filament switching G-code, precision machined parts, the 1-piece internally polished Prometheus V2 nozzle, and powerful geared extruder stepper motors, we are able to reliably print objects with hundreds of filament switches in a single print!



This enables you to print multi-color objects, print with support material, or create multi-material prints!


Multi-Color Worlds printed in ABS plastic.


Propellers: Yellow PLA with PolySupport support material on the left; Nylon Alloy 910 with Guidel!ne PETG support material on the right.


Composite wrench printed with Colorfabb XT-CF20 Carbon Fiber perimeters and Colorfabb XT Clear infill.


Glow-in-the-dark objects printed with Colorfabb Glowfill

The objective with this new product is to eliminate the difficulties and quality issues associated with conventional methods of dual extrusion (calibration, nozzle dripping, color contamination, extrusion pressure, etc...).

The Prometheus System is a unique approach to multi-filament 3D printing that is designed to solve all of these issues! By using a single nozzle, The Prometheus System eliminates the calibration and nozzle dripping issues that affect dual nozzle configurations. In addition, by feeding one filament at a time into a single hot end, The Prometheus System prevents the problems with color contamination and increased extrusion pressure that are associated with recently popularized color mixing hot ends. This results in clean color transitions and flawless printed parts:







I am really excited to hear what you all think of this new product! We have been working hard to find the optimal solution for multi-filament 3D printing and we think this is it! Please use this thread to share your thoughts on our new product and our unique approach. We are committed to working with the open source community and we will be releasing this product under the CC BY-NC-SA 3.0 Creative Commons license.

Our Kickstarter campaign for The Prometheus System will launch on September 6th. You can sign up at http://distechinnovations.com/ to receive a Kickstarter launch notification and get the first pick of the discounted Early Bird rewards.

Happy Printing!
