Prometheus System - Components


Prometheus V2 Hot End

The Prometheus V2 is a high-performance all-metal hot end.

It features a specially polished 1-piece nozzle which enables reliable filament switching for multi-color and multi-material 3D printing.

The ProStruder is a powerful 5:1 geared extruder.

The PTFE tubing extends up to the drive gear creating a constrained filament path through the extruder, while the geared stepper motor provides enough torque to enable reliable filament switching.

The ProFeeder directs the filament path from two extruders into a single filament guide that feeds into the hot end.

This carefully designed component is compact, lightweight, and constrains the filaments to prevent buckling in the feeder.

Prometheus V2 Hot End

The Prometheus V2 is a customizable all-metal hot end that can print any filament up to 300C. Machined from a single piece of stainless steel, the 1-piece nozzle allows for easy assembly and eliminates all internal “melt-zone” junctions.

Prometheus V2 Hot End - Testimonials

“[The Prometheus V2] worked perfectly fine with every material from ABS, PLA, Taulman Bridge Nylon, and even Nijaflex. None of those plastics ever jammed…A solid hot end overall, with the ability to reconfigure it in certain situations.”

Thomas Sanladerer (YouTube Reviewer) - [Tom’s 3D]

“Based on all the hot ends that I have reviewed [the Prometheus] is the one I would put on my personal printer in terms of overall performance, flexibility, ability to do different things, and price point.”

Michael Zenner (YouTube Reviewer) - [Zennmaster 3D Printing]

"I have tried many different hot ends in the past. After growing frustrated dealing with jams and poor print quality, I came across this unit and had to try it. The first one I bought was the V1 then the V2. Both have been exceptional!!!
I am about to buy a third one...
This is the only hot end I will buy."

Alain Spalard (Customer)

“I've bought a combination of 6 [Prometheus] V1's and V2's, and they're the only hotends I've found that can truly print 30+ hour prints in PLA without jamming. By far the best hotends I've used.”

Jesse F. (Customer)

“I've owned two other "all metal" hot ends from other makers as well as a basic jhead. The Prometheus V2 is a class above all the others I've used.”

Forest B. (Customer)

“I currently print very smooth models/props at 218°C using PLA and couldn't be happier. For the price and quality you can't go wrong, it's a brilliant little device.”

Jon Catt (Customer)

“I bought my first Prometheus V2 18 months ago and now I have them in all three of my printers.”

Tristan Hasspieler (Customer)

“Seriously, just get a Prometheus and don't worry about your hotend ever again.”

Abram Thau (Customer)

A must have for your Rostock Max V2 or any printer for that matter. Looking forward to what's next from Distech!”

Nicholas Allen (Customer)

Prometheus V2 Hot End - Features


1-Piece Polished Nozzle

Machined from a single piece of stainless steel, the 1-piece design eliminates all internal “melt-zone” junctions making hot end leaks a thing of the past.

Professional internal polishing along the full length of the nozzle reduces friction in the hot end and eliminates jamming when printing PLA.


Fully-Customizable Design

The customizable design of the Prometheus V2 can be used in both direct or bowden configurations and can be used with a variety of nozzle sizes: 0.3mm, 0.4mm, 0.6mm, and 1mm.

The variable length "melt-zone" allows for the hot end to be customized according to your needs. From high precision to high speed printing, Prometheus V2 does it all.
