Replacement nozzles? Printing with abrasive filament


#7

Do you know if they are using standard nozzle sizes or something propriety? I haven’t received my printer yet so I can’t check. I was looking at getting some nozzles from E3D. http://e3d-online.com/E3D-v6/Extra-Nozzles

The installed nozzle doesn’t look very similar to the E3D nozzles you linked. They look more like the ones I found on Amazon: http://www.amazon.com/Printer-0-4mm-Extruder-Nozzle-1-75mm/dp/B00L4UXQ42

You could also see the pics from this thread to get a slightly better view of the nozzle: Printer Head bottom cover started melting

I’m honestly not 100% on the differences in nozzles or whether the installed one is meant to be replaced, but I would assume they went with a standard, and relatively cheap, nozzle for mass production.


#9

@Simon Can you confirm which are the correct nozzles?


#10

Update:Seems like @AmnNate has found some appropriate nozzles. They are the Mk 8 version with a M6 X 1 male thread to the printer


#11

Did someone buy a replacement nozzle yet? If so which one?

Would these work?


#12

Yes I have that nozzle on the printer right now.


#13

Ok good thanks for the info :slightly_smiling:

edit:
I ordered some from there…

might be interesting for other people in europe.

How about changing the heatbreak to a coated one? Did not have a look yet… is that a possibility?

There is a Kickstarter project being run by the people behind https://dddmaterial.com to produce 0.4mm tungsten print nozzles for 1.75mm filament. Tungsten is better in hardness, thermal conductivity, and expansion coefficient than either brass or steel, making it better for high-temperature or abrasive filament. They are, however, significantly more expensive than brass or steel nozzles.

Backed, thanks for the tip. :slight_smile:


#16

I bought these - https://www.amazon.com/gp/product/B01BDL4MXA/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Hi everyone! I’m looking to purchase a new nozzle but I was wondering if the links here are exactly the same dimensions as the original? If not, did the machine work just as fine with it or did you have to do adjust the layer height (for a longer/shorter nozzle) via flux studio? thanks (I’m hoping to purchase the one @pmbroth linked it looks pretty good)


#18

I just replaced the original nozzle that came with my Delta. I’ve done around 750 print hrs on it maybe used 5kg of standard PLA filament, nothing abrasive. As you can see my nozzle is pretty worn down. I bought some basic 0.4mm brass nozzle from Ebay and I’ll provide an update once I’ve done a few prints.


#19

Cool, I thought you were a new user, how in the world did you do 750 prints and use 5kg? I mean if you couldn’t setup your delta sometime ago then your new… right?

Just curious. And please post the ebay link too, good luck!

I’ve had my Delta for just over a year now, I’ve just had many issues trying to connect to my Delta as when I set it up I didn’t move it for almost a year then when I decided to move it I had all sort of issues connecting via wifi and usb.

Haha yeah I do many prints at 100 & 50 microns so some prints take up to 30hrs +

Here is a print before I changed the nozzle (Mind you there is some under-extrusion from my S3D settings not calibrated) But I could see the quality of my prints degrading.

(100 Micron layer hieght)

I did this on the new head @ 50 Micron layer height (Currently testing if watertight)

I did have 1 issue where I had PLA leaking out the top of the hotend. I initially thought it was coming out of the side of the nozzle. I had to take most of the tool head apart to clean it up. I think when I was taking the nozzle off, I might have loosened the hotend and PLA was back-flowing through the top of the hot end. Anyway it all works fine now.

These are the nozzles I bought

I also bought this nozzle as I want to start printing with wood, glow, carbon filaments


Filament overflow near nozzle, no problem printing but ugly lumps dripping

unless he printed 750 Marvins I am not sure how he did that… that only about 6g per print.

joke aside nice vase.


#22

Yeah, loosening the heatbreak was the same problem I had… I ended up removing the nozzle due to a really bad clog for cleaning, and I ended up with the backflow of PLA oozing out through the printhead. Thankfully I was onto it right away as I was watching the print start up again, and after two disassemblies of the print head to work out what was going on I cured it of that ailment for good… the heatbreak will NOT be loosening itself in the life of that print head! :wink: :open_mouth:


#23

Thank you @debre and @pfeerick I’ve had this problem for 7ish months now, after 2-3 prints I would always have to open the module base and clean the junk out and around the hotend (always thought it was the nozzle). Took the courage to dismantle and sort it out yesterday, it’s working perfectly now thank you very very very much for sharing this valuable info! Love and respect!

UPDATE: Couple days after, seriously this is an unbelievable revelation, I feel like a new man! I can print without worrying about the thread leakage woooooh!


#24

So I’ve been using the micro Swiss nozzle for about 2 weeks now and I can say that it works just as good as a regular brass nozzle. Have printed with flexible, wood and glow pla and haven’t seen any signs of wear. I did notice that there is a bit more stringing on prints even with retraction set to 12mm. It seems that the coating on the nozzle has a very low friction as when I change filaments the excess pla in the nozzle drips out of the nozzle, however this rearly happened on the brass nozzle


#25

cool! the flux store is now selling nozzles separately.


#26

So after printing around 10hrs (60g) of abrasive filament I can say the Swiss micro nozzle are no better than statndard brass nozzles
