    It isn't a home based thing yet. I've used specialists in NYC and Belgium. The bronze is done by printing a high resolution wax, and using traditional jewelers' lost wax casting techniques to cast bronze, silver, and other metals.

    These movement plates are made by using a super high resolution wax jet printer that shoots tiiiiny drops of wax into stainless powder. Then the wax-steel mix is sent into a kiln to burn of the wax and sinter the steel. This is similar to MIM, metal injection molding, where a metal/binder goo is injected cold into a mold, and then the binder is burned off and the metal sintered. I believe Citizen was the first do use MIM for cases.

    The grey case with the old Longines movement is made by SLM, Selective Laser Melting. A powder of Grade 5 titanium is zapped with a tiny laser to weld the powder together, then powder is reapplied, re-lasered until it forms a part.

    I believe Holthinrichs watches uses the SLM or the similar DLS (direct laser sintering, sintered product without needing the kiln stage).
    The cases the process lets him do are awesome:



    This, in my opinion, is a far better execution of skeletonized lugs than AP's Code11:59. He's been doing these for at least a year, maybe two prior to AP.

    His first time at Basel is this year. Michiel is a really good guy and helped me out with tech and sourcing questions .
