Hey Everyone, Thanks so much to all who have supported this campaign! Tomorrow is the last day of the campaign and I have now raised $7000. I am very thankful for the incredible support I have received from the community and I am really excited to bring Prometheus into existence! I am confident that Prometheus will make many printers very happy and I can't wait to start shipping! The productiby RP Iron Man - Crowdfunding Projects Announcements
Hey Everyone, Thanks for all of your feedback and support. The campaign is now over 200% Funded! I just wanted to let you guys know that I have finished sorting out the details for bowden integration. Since I do not have the quantity demand to make two different versions I decided to make all of the Prometheus Hot Ends bowden compatible. I made some minor changes to the heat sink design that alby RP Iron Man - Crowdfunding Projects Announcements
Hey Guys, Thanks so much to everyone for the continued support. The campaign is now 180% funded! Just a few updates. It looks like the Early bird perks are running out with just two Prometheus 1.75mm Early Bird perks remaining! Many people were asking about bowden integration and I have been working on a solution for this.

Hey Everyone, Thanks for all of the ongoing support. The campaign is now over 140% funded! A few updates for you all. I have slowly been receiving more of the parts for the Prometheus Kits. The small cooling fans and metric hardware just arrived and there are other parts on the way! I have also been sorting out the stretch goals.

Hey Werner, I was wondering about what you have been working on over the past few months? It's been a while since you last posted a video. Any further news/developments with the BerryBot3D? A while ago you mentioned starting a Google Group for people who want to build their own BerryBot.

Hey Guys, We are now well past the funding goal. Thanks so much to all of the supporters! I have received a lot of input about possible stretch goals and I am currently weighing all of my options. Just so you guys know, I plan on offering BOTH 0.25mm and 0.6mm nozzles in the future, but I am just trying to get an idea of what people are more interested in.

Quoteekaggrat @RP Iron Man the m4pipe with 1.75mm and m5 pipe with 3mm should work fine as the wall thickness of the barrel would be less and the heat transferred would be also low...

@ekaggrat If you read closely into my design of the Prometheus Hot End you would have found out that there is a reason why I don't have a "thermal break" (machined groove) in the 1-piece nozzle and I actually designed an alternative. Since Prometheus is a hot end with adjustable "thermal zones", the "transition-zone" has a different position on the 1-piece SS nozzle depending on the user confiby RP Iron Man - Reprappers
Quoteturutk Your heatsink design seems thin due to shape. Can I combine 2 of your hotends and use them with a single 4cm fan? That's actually what I had in mind with the thin heat sink The thin heat sink design allow two Prometheus hot ends to be placed very close together for Dual extrusion set-ups. Using a single fan may be sufficient to cool both heat sinks, though I have not tested this.by RP Iron Man - General
Great News! Thanks to all of the supporters! Prometheus is now fully funded! I really appreciate all of the support from everyone in the 3D printing community. This hot end has great potential and thanks to you guys it will soon become a reality! Now that the funding goal is behind us I am thinking about possible stretch goals to keep things rolling.

Yeah, I don't think there should be any issues with food safe usage of this hot end. The internals of the SS 304 Nozzle are also polished and cleaned so there is no risk of machining residue and gunk being printed into your food safe part either. I really want to experiment with T-Glase once I get some 0.6mm nozzles. I actually tried it with 0.4mm nozzles and it worked intermittently but just puby RP Iron Man - General

Hey Cameron, It's SS 304 for the nozzle. Unfortunately I only offer 0.4mm nozzles at this time and you really can't print T-Glase with anything smaller than a 0.6mm nozzle because of the insane amounts of back-pressure, really sorry about that. Ericby RP Iron Man - General
The reasons we are still using thermistors is because: - They are cheap - They are easily accessible - They are compatible with all electronics boards - They are reliable up to 300C which is good enough for the majority of applications I really think that we should be moving toward thermocouples as the standard for temperature sensing.

Hey guys, Lately I have been making some last minute changes to the heater block design in order to allow for a future thermocouple upgrade. Once the design goes into production it will be a pain to change anything so I am trying to get all that out of the way now. I have been talking with suppliers about thermocouples and as I expected M6 threads seems to be the standard mounting configuration.by RP Iron Man - General
