What are folks’ recommendations for places that 3D print in metal (say, for math sculptures)?

I never have printed in metal before, but I’ve got a couple of designs that I’m really happy with…(and there was prize money from the math fest art show!)

An open knight's tour of a 128x128 chessboard. The knight starts in the lower left corner, finishes near the lower right corner, and visits each of the sixteen 32x32 regions in the same order that they'd be visited by a second-stage Hilbert curve. #mathart

$Orange goo containing plankton floats over and into the fractal surface of infinite holes. The surface is based upon an Apollonian gasket.$

Not receiving a salary raise in an era of rampant inflation is essentially a pay cut. But so is the laying off of support staff whose jobs faculty are expected to absorb.

Doing tech support, extra advising, admin assistant duties, etc. = less time for the work of being a teacher / faculty member.

This is how you interview people from the Trump admin; past , present, and future. Full stop.

So well done.

Me: "So which country should @aoc.bsky.social go back to?"
Mick Mulvaney: "She's an American citizen."
Me: "So why did Trump tell her to go back to her country?"

I asked former Trump WH chief of staff Mulvaney if he ever challenged his then boss on his racist tweets.

The US will stop making pennies in 2026, which got me thinking about what to do with a giant collection of too-expensive, low-value coins. Here's what I made with them.

Sick of everything being Orwellian or Kafkaesque. I demand more Scarrylous situations, where animals drive vehicles and run small businesses.

Gary is a former student of mine! I need to pick up Vera. I loved his last two novels.

A knight's tour of a 32x32 chessboard. The knight's path is unicursal. If you start in the lower left corner and follow the path move by move, you will visit each square once and only once and end near the lower right corner. Inspiration: Szpakowski's linear ideas. #mathart #mathsart #orms #chess

Getting excited for the Bridges fashion show tonight! On the runway will be the world premiere of my black and white rhodium plated knight's tour jewelry!

Shiny angular jewelry with black and white accents.

I'm interested in learning how to do this (either by hand or with a machine).
