I just want to share this with you guys, the most abrasion resistant nozzle ever made. I have been involved with this project since the very beginning, trough all the development, and i am proud to be a part of it being launched today.
We (as in 3DVerkstan) has been Joint developing The Olsson Ruby nozzle with Anders Olsson, most known for designing the Olsson Block for the Ultimaker 3D Printers, and it has been a most exciting experience where we have learned incredible amounts about materials, machining and nozzle design. We have had about 50 community testers printing a incredible amount of hours with different revisions of the nozzle during the last year, and we finally have a product ready to launch!
If you have any questions, just ask me here and i’ll try to answer
@Jeff_Dewe : Originally we did not even believe that we could make them to sell at a sub-100$ price point, the custom high-precision ground rubys and the machining and assembly to mount them reliably costs a lot, especially in comparably low volumes.
@Miguel_Angel_Salmer1 : One of the testers did print over 8kg carbonfil with one of the prototypes, and under a microscope the front surface which usually wears the most was indistinguishable from before the test, there is a picture on the website from that test.
@denix Just by going to the e-shop links on the site, none of the places I saw offers 1.75, all seem to offer replacement for Ultimakers… I would like to be proven wrong.
Wow. I want one. Considering that e3d nozzle are like $15 USD… I’m sure I’ll go thru few of those. So if this can last as long as few of the journal ones, then I’m sold.
The price point destroys the viability of this for all but the most hardcore or commercial ventures. You can find cheap, reliable nozzles from Chinese suppliers. Even with frequent nozzle changes and very abrasive materials you could print hundreds or thousands of items before it broke even with the cost of one of these. For a hobbyist, that’s a lifetime of printing abrasive materials just to break even.
For a commercial setup, for maybe someone constantly printing metal jewelry (or other metal/abrasive filaments), perhaps this is a good buy. I have a hard time imagining this makes sense for most.
That said, of course, my first reaction was, ohhhhh.
@Josef_Jelinek , @denix Right now only the 2.85 / 0.4mm version is available for sale, that was our main focus since we are a Ultimaker distributor and reseller and don’t use 1.75mm printers ourselves.
A 1.75 / 0.4mm E3D-Compatible version is in the works tough, the latest iteration went out to testers last week for verification. One of the obstacles we have found about 1.75mm is the wide variety of “almost similar” undocumented nozzles that exists for different printers, with slightly different geometries.
Please use the form on the website to submit interest so we can make a better guess on what type and quantity we should focus on for the next batch.
@Felix_Garcia_Chaco We have only tested up to 8kg with a single nozzle, but from the results of our testing, i would not be suprised if you could go trough a hundred spools of carbonfil or XT-CF20 with no reduction in print quality, so yes it will last
The only person that has been able to wear it down with printing is the inventor Anders Olsson himself, and he used a Boron Carbide (B4C) filled ABS filament that is crazy abrasive (regular nozzles last single-digit hours and he can often not even finish a single print with a brass nozzle)
@Erik_Cederberg so you really finished the idea of a ruby tip nozzle
Congratulations to all involved people.
I saw the first mindstorming of the project, I think it was also shared here in the 3d printing group.
@Erik_Cederberg Yes I guess once you include the cost of a ruby it would make production cost a lot more expensive, is your company also going to supply parts, Like if someone messes up the threads and wants to reuse the ruby, Or if someone breaks the ruby by running it over with a tank, lol I don’t know really, Just wondering if there is replacement parts support, Might make it more inviting to people if they know things can be fixed and not just replaced, Maybe like a exchange program who knows, just an idea.
@Jeff_Dewe : Yes, these are quite a lot more expensive to make than our regular nozzles (by multiple tenfolds). We will probably not offer users to get separate replacement parts as spares since they are dependent on a precise assembly that is not easy to do without our custom assembly jigs, also getting the ruby out from a assembled nozzle without damage is a bit tricky. Still, i appreciate the suggestion, we will think about what we can do!
@Jim_Christiansen : We have tested a number of iterations, our first designs had less protrution of the ruby, but the final one performs better in terms of print quality.
