Hey Jack, nice work! I love the idea, this is an area where customization is very valuable and automated customization like this can save a lot of time and headache. What are you using to generate your geometry? Any plans on doing other jewelry types? One thing I could also imagine people wanting is delivery of SLA-printed prototype rings to get a better idea of the look and feel.

Thanks! To generate the geometry I first generate a bitmap image texture using fabric.js on the client side. I can then import this texture into blender and use it as a displacement map on a ring blank. I apply the displacement to the geometry and export as STL for 3d printing. Blender is scriptable so this can all be automated (although it isn't yet). I do hope to add other jewelry types. My next idea is necklace pe…

Yeah fair enough. You can get SLA parts electroplated, although it will still be more matte than glossy unless they are polished, which would increase the price, and it would probably be cheaper to just do the brass casting option at that point.

Also- one of my coworkers recently got a custom wedding band and he went through a similar process to the one you went through of looking at vendors, trying to find the right material, etc. He wanted a pretty customized ring, and one of the things he added was the embossed outline of a lake that had special significance to him. Not sure how many people would have similar requests, but it would be cool to allow something similar. Maybe just have the option to upload a black and white picture and use that to create an embossed feature.

You can upload any image on my site. I convert to black/white and give you sliders to adjust brightness, smoothness, or do edge detection. Currently I only offer engraving rather than embossing but it wouldn't be too hard to emboss instead.

Hi everyone! I built Lulim Jewelry after spending some time figuring out how to design and 3D print my own wedding band. My day job was in the 3D printing industry and I knew how far the technology had come so I busted out the CAD tools and designed a ring with my wife's fingerprint on it. I thought the processes could be much easier and thus Lulim was born. The website is built with Vue.js, Canvas.js, and Three.js.…

This is a super neat idea. I have made wedding bands for friends over the years, I usually provided a stainless steel band the right size to wear for a week or two and found that often we would tune the sizes by 1/4-1/2 size or thickness. For expensive bands, it might be neat to offer a trial size for a reasonable fee since wedding rings can have a long life.

I choose lulim as the name after lu-lim, the ancient Sumerian name for Saturn[0] (the planet with rings!) [0]: https://en.wikipedia.org/wiki/Classical_planet

Interesting. There's no way they could have seen the rings back then. I wonder if there's a connection.

Sumerian is a linguistic isolate: no one has ever been able to demonstrate a relationship with any other language. Which is itself pretty mysterious!

Akkadian, which displaced it, is a Semitic language, which became the lingua franca of the Ancient Near East. Aramaic is somewhere between a relative and a descendant; more the former, Akkadian stands to Aramaic very roughly as Latin stands to English.

So... probably not? I don't know if any Sumerian loanwords have been identified in Akkadian, but it would surprise me if there were absolutely none, the Akkadians adopted cuneiform to write their language, and their empire was the successor to the Sumerian states.

If anyone can point me at resources on the subject, I'd enjoy that, I've always found that part of history fascinating.

When ordering on my site I have an option for "I dont know my size", in which case I send the customer a ring sizing kit. I've heard others say it's important to wear the ring for some time so thats something I should take into account.

One thing I've considered is adding an option to order a brass version of the ring first so the customer can see how the design will come out and test the fit for a few days.

BTW: The name "Lulim" is the Arameic for spiral, in Modern Hebrew there are words like "לולין" ("Lulyan" / acrobat) that take this root) See: http://www.de-bruyn.it/english/0557_lulim.shtml

@fortan77, That's fascinating! How do you know this? Do you speak Arameic? I happen to speak Arameic, but it's so crazy to find someone here on HN who might speak Arameic.

Anyone who has formally studied the Talmud knows it, at least in the context of the Talmud.

In modern Hebrew Lulim means "chicken coops" :)

Oh no! I hope any of my potential Hebrew speaking customers have positive experiences with chicken coops.

I actually checked the About page to see if this is an Israeli project. Maybe someone started this business in an old chicken coop in their backyard or something :)

Why is the custom design only on the inside? I think I'd be much more interested if it were on the outside.

I personally liked the idea of a simple classic ring on the outside with the personalization only on the inside, but I acknowledge that is just my preference. I do plan on adding outside customization soon but I wanted to launch ASAP. If you are interested I can pretty easily make a ring with the design on the outside for you.

You are smart to launch with an MVP that does the one thing so well. Mad props.
