My wife's father was a gemologist and metalsmith. When we got married 42 years ago, he made both of our wedding rings -- lost wax casting, of course, since 3D printing wasn't a thing. Mine is a plain rose gold band, hers is antiqued gold leaves surround a diamond (he was an experienced gem faceter, but would not touch diamonds, which he'd rarely worked with, so ours came from a diamond dealer). He had me pour the gold for both rings. It's nice to have a story to go with them!
- gregschlom 2y ago> lost wax casting, of course, since 3D printing wasn't a thing Just to nitpick, even with 3D printing these days, the process is still called lost wax casting. The printer prints a wax version of the model, and then the plaster is poured around it to make a mold and the wax model is melted out. The only difference is that the wax model is made by a 3d printer rather than by hand.
- ortusdux 2y agoThere are burnout printer filaments and resins as well, so I've heard it referred as 'lost plastic' casting https://helpcenter.phrozen3d.com/hc/en-us/articles/6325283749529-Burnout-schedules-for-Phrozen-Castable-Resin https://helpcenter.phrozen3d.com/hc/en-us/articles/632528374...
- alvah 2y agoTo nitpick your nitpick, lost PLA casting is most definitely a thing; no wax required.
- willcipriano 2y agoI've seen: 3d print a part (resin printer), make a mold from the 3d printed part with modeling clay or whatever, cast wax in the mold and then sand cast metal with the wax casting. I think the 3d printed part wouldn't burn away as cleanly as the wax that is designed for that purpose. Probably faster if you want more than one as well.
