Title: Earrings - Twisted Arc Type C
Post by: Jeffin90620 on December 10, 2019, 06:54:42 PM
Designed a shorter set of earrings where the elements are nested.  As before, these are interlocked, so there are two separate pieces with a 1mm minimum separation between them for 3D printing.

I used the Extract Entity / Extract face from body (F) tool to create 1mm objects to check for intersections.  It doesn't work with the Sphere object (something to address?).

If I were to experiment with DMLS, I could pretty much eliminate the clearances between objects, but I haven't seen them produce in metals suited for jewelry.

I'll bet the finished product is gonna be gorgeous. Will the inner and outer rings be the same material?

Oh, yes... polished brass for each.  I was just separating the two interlocking objects for clarity.

I like the polished brass as it is a close approximation of rose gold plating, but because it's solid, it won't have visible abrasion.

Nice. I was visualizing rose gold outer rings and green gold inner rings.

Never heard of green gold.  Brief research indicates it is a misnomer, with the actual appearance being various shades of white gold.  Not an option at Shapeways.

It's real. Over the years I've given my wife several pieces of jewelry made of rose gold and green gold. The latter actually is green-ish; very pretty. Google "Krementz green gold." (Sorry to hear about Shapeways.)

isn't green gold is an alloy of silver and gold? Used for enameling.

Yes and no, Nikki. The stuff I'm talking about is definitely green in hue. The stuff you're referring to is also called electrum, and according to Wikipedia it isn't really green. Wiki sez, in part...

"Electrum is a naturally occurring alloy of gold and silver,[1] with trace amounts of copper and other metals. It has also been produced artificially, and is often known as green gold. The ancient Greeks called it 'gold' or 'white gold', as opposed to 'refined gold'. Its colour ranges from pale to bright yellow, depending on the proportions of gold and silver. "
