    3d designer for 3d printed lugs, any suggestions where to find one?

    Hello!

    I am looking for a person or a company who could perhaps accept order for making 3d files for 3d printed steel lugs, similar as these ones in the image, any suggestions who I could contact about such work would be most welcome, thanks!

    As a designer of parts, I'd speculate that you'd be paying several thousand dollars. Probably well into the $10k range if you don't have a proper architecture for laying the lugs over, which few do or understand. If you wanted really well designed parts, you'd be paying a lot more than that.

    The lugs you have pictured that Metier Velo LLC uses are actually 3D printed titanium. He is somewhat local to me and we spoke several years ago, 2017 maybe? Anyway, a very basic description of the process used to make those lugs is that they take a pile of titanium powder and blast it with a high powered laser to melt it together in whatever shape is desired. At the time, he told me only two manufacturers in the USA were using this process, one was in Illinois and I can't remember the location of the other.

    Don't know if the process works with steel, but it sounds high tech and probably spendy. His bikes weren't cheap, but they looked super cool. I know that wasn't super helpful information, but that's what I was told about those lugs, according the the guy that had them made.

    I know almost nothing about this process, but I would think blasting powder with a laser would produce a product with a high level of porosity and voids.

    I just checked his website. Looks like there is an email, so you can contact him and ask him about it. Looks like like he moved to New Mexico. He used to be just outside of Salt Lake City.

    Here is one place in the USA that has the equipment to make that type of part from steel. The process is laser sintering.

    This is a newer attempt to 3D print metal parts. I have no experience with it but they claim it is more cost effective than SLS.

    I deal with additive manufacturing frequently and I can offer that in my experience 3D printed metal parts are so expensive that the only production applications I have seen where it is economically feasible is in Aerospace/Defense and medical implants. That is because in these applications cost is no object.

    Every time I have quoted something to be made with this process I have ended up tooling it as a casting or machined part due to the cost.

    Tom Sturdy (https://www.sturdycycles.co.uk) in the UK has been making Ti bikes with 3D-printed lugs for a while and seems to have his process pretty-well nailed down. Pricing isn't completely off-the-map for a one-off, handbuilt Ti frame either. I saw some of the unprocessed parts when I visited the Bicycle Academy (https://thebicycleacademy.org) in 2019 and the staff all seemed happy enough to talk about the process. Whether anyone there would be able to do the actual design work for you or put you in touch with their supplier, I don't know.

    Contact Kannon in Japan.

    He's posted in his IG that he's willing to help people do ti and steel 3d printed lug work.
