For the past several months, we have been working on an upgrade for the Prometheus Hot End called "The Prometheus System" which is a unique solution for multi-filament 3D printing! This will allow you to print multi-color objects, print with support material, and print multi-material objects with composite structures and special materials.

We are a couple of weeks away from the Kickstarter campaign for this new product so I wanted to reach out to keep you all in the loop. Check out the Kickstarter landing page and sign up to receive a notification when we launch our Kickstarter. By signing up you will be the first to know when we launch and get the first pick of the discounted Early Bird rewards!

I will start a new discussion thread for "The Prometheus System" next week when we release the teaser video along with more information about the product. We are really excited about this new product launch and we hope you are too!

It has been a while since I last posted here. I have recently put together a comprehensive user guide for the Prometheus V2! This guide outlines the trade-offs involved in configuring the Melt-Zone and Transition-Zone of the Prometheus and will help you get the most out of your hot end. Check it out:

User Guide

We are also now offering new Prometheus V2 nozzles in 0.3mm, 0.4mm, 0.6mm, and 1mm nozzle sizes! These extra nozzles are available here:

V2 Nozzles

The nozzle length scales with orifice size so the larger orifice nozzles can be assembled with longer Melt-Zones to allow for higher flow rates. It also makes nozzle identification much easier

24V electronics are now available as an option for those of you who run 24V printers (http://www.dta-labs.com/collections/hot … metheus-v2).

The old V1.1 nozzles are now heavily discounted for quick sale at just $15.50 each (http://www.dta-labs.com/products/1-piece-nozzle-v1-1).

Our 10% off sale ends on August 14 so be sure to grab your Prometheus V2 before it's over!

Happy Printing

It has been a long time since I posted in these forums. It’s good to be back

With the success of the Prometheus hot end and hundreds of happy users around the world, we have received a lot of feedback about our product. In an effort to perfect the Prometheus Hot End we have developed Prometheus V2, an optimized, simpler, and more professional version of the original Prometheus V1. The goal with Prometheus V2 is to eliminate all of the quirks of V1 while further improving performance and user experience.

A few of the improvements over V1 include a quieter cooling fan, a professional heater cartridge and high temperature sleeving on the thermistor, simplified assembly with no soldering or Kapton tape required, embedded bowden collet for both 1.75mm and 3mm versions, and many more.

We are now selling Prometheus V2 (Beta) hot ends on our webstore

The objective of the beta release is to obtain feedback about our improvements and suggestions about anything else that can be further improved before the official V2 release.

There is a limited time offer of 10% off all store purchases for early adopters so do not hesitate to grab your V2 hot end today!

We also now offer 0.3mm, 0.4mm, and 0.6mm nozzles with V2 (which are also backward compatible with Prometheus V1).

They say a picture is worth a thousand words so I’ll just show you some pictures of Prometheus V2 instead of just blabbering on about it:

Below is a comprehensive outline of the design features of Prometheus V2:

V2 Design Features

- Durable, actively cooled, compact, all-metal construction for high-temperature extrusion up to 300C.

- Professional internal polishing along the full length of the nozzle creates a near mirror finish which reduces friction in the hot end. This eliminates jamming when printing PLA, even with long retractions in a Bowden system.

- The nozzle is 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.

- 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.

- Heat Sink efficiently dissipates heat from the nozzle maintaining a sharp 2mm thermal transition at temperatures up to 300C. Optimized heat dissipation allows for a quieter cooling fan and minimizes vibrations.

- Internal geometry allows for the Bowden collet to be inserted directly into the heat sink enabling easy compact Bowden integration for both 1.75mm and 3mm versions. All heat sinks are Bowden compatible and switching between Bowden and Direct configuration takes just a few seconds.

- In both the Bowden and Direct configurations, a PTFE tube passes into the heat sink and facilitates a smooth filament path directly from your extruder into the 1-piece nozzle. This improves performance when printing flexible filaments like NinjaFlex. [Note: PTFE tubing is not subjected to high temperatures within the hot end.]

- The stainless steel nozzle does not wear like conventional brass nozzles. No need to replace your nozzle when printing abrasive filaments such as the Stainless Steel PLA, Magnetic Iron PLA, or Carbon Fiber PLA offered by Proto-Pasta.

- Compact design conserves z-height and allows two hot ends to be placed as close as 16mm from each other, conserving print space in a dual extrusion set-up.

- Professional heater cartridge and high temp sleeving on the thermistor means that no messy Kapton tape is required! The thermistor is held in place with an M3 bolt and washer.

- Standard J-Head groovemount dimensions means that Prometheus V2 should fit most extruders and is a drop-in replacement for your old hot end.

I’d be happy to hear any comments about Prometheus V2! Let me know what you think and just ask if you have any more questions

Happy Printing!
Eric

There is also very little difference between a 0.35mm and 0.4mm orifice nozzle. I have printed down to 50 microns so you should not have difficulty printing high detail items

Let me know if you have any more questions!

Eric

I prefer being able to change orifice sizes also for different materials or printing needs. I still have my original .35mm SD hotend with all its shortcomings but I like the smaller size for ultra fine ABS prints with my tiny scale vehicle models for N and Z model railroading. and have gone through over 1 2kg roll the past year making them with near same detail as a powder type $50k 3D printer on an ol SD2. just my observations

Sorry about that, I completely forgot to mention that I am Canadian so we had Thanksgiving in mid October!

It is different for Americans so I should have mentioned that!

Eric

Michael "ZennmasterM" Zenner just posted a review of the Prometheus Hot End!

I hope you all enjoyed your Thanksgiving weekend!

I received the second batch of machined parts about a week ago and they look great! I just finished packing and shipping all of the remaining orders this past weekend.

Now that all of the pre-orders are out the door I am shipping all new orders within 3 days. Don't hesitate to grab your Prometheus Hot End and be sure to get in touch through my website (http://www.dta-labs.com/) if you have any questions.

Thanks so much for all of your support!

Happy Printing

Eric

It's great to hear that your hot end arrived. I am looking forward to hearing about your experiences!

------------------------

Hey Everyone,

I am so sorry about the late update.

As of about 2 weeks ago I finished shipping all of the Indiegogo hot ends. There are only a couple of hot ends that have yet to be shipped. If you have not received an email about this then your hot end has already been shipped. If you have not yet received it then it is likely still on its way.

The second production batch is almost ready so I expect to be shipping pre-orders within 2 weeks. I am going to be shipping orders as they were received so don't hesitate to grab your Prometheus Hot End early!

If you have any questions about anything really feel free to get in touch via the contact form on my website:

Thanks so much for all of your support!

Oh and Eric! Nice work! It looks very tasty.

I am really sorry about the delayed update. A lot has been happening and I just haven't had the time to post. I hope you all can understand!

It's been a long road but everything is finally coming together! Last week I received a few samples of the production hot ends and they look and work great. The quality of the machining and overall finish is exactly what I was hoping for.

Prometheus in all its glory

The complete production batch of parts will arrive on Monday. I have all of the other components sorted so I am just waiting on the rest of the machined parts.

Bags of kit components:

Tomorrow I am going to try to put together a set of step-by-step instructions for assembly.

In addition to this startup business, I work as an Industrial CNC Router Operator so unfortunately I can't spend all of my time on shipping, but I am going to be working on shipping out these hot ends as fast as I can!

I will likely start shipping on Tuesday next week. I will be shipping the orders in the order I received them and I realistically should have ALL orders (including the orders made after the campaign) shipped within the next 2 weeks.

I can't wait to release Prometheus into the wild! I hope you guys are half as excited as I am about this I am confident that Prometheus will make many happy printers.

If you have any questions, comments, or last minute changes to your shipping address, just let me know.

Finally, I would like to extend my utmost gratitude to all of those who supported my campaign. Thank you so much for believing in Prometheus, and also for believing in me! Creating the Prometheus Hot End has been my dream and now it is finally coming together thanks to all of your support I now have my own 3D Printing startup: DisTech Automation (http://www.dta-labs.com/) running and I have several ideas that I plan to bring to the 3D Printing community in the future. I hope I will be able to give back to the community by sharing the Prometheus Hot End and all of my future innovations!

Thanks, guys.

Happy Printing :-)

Eric
