I am looking to make some high performance copper parts with internal cooling channels. I have seen a few references to Electron Beam Melting and Direct Laser Metal Sintering using copper in journals. It generally required more power but gave good results comparable to more common materials. I have not been able to find anyone offering these services to the public. A number of services are available for aluminum and steel alloys, but no copper.
Granted, most of the top search results you get these days are geared more towards the trendy and hipster set rather than actual parts manufacturing so Maybe I need to dig deeper still...
Does anyone know of any suppliers offering copper additive manufacturing services?
I mean itโs one of the most beautiful weapons in the gameโs history. Very happy the damage reflects its gorgeous appearance.
Wonโt be leaving my inventory any time soon.
I got laser hair removal for the first time on my face, I was so nervous that I wouldn't see the results right away, but holy crap I feel so good afterwards. It did hurt a bit, but nothing I couldn't handle. It felt like such a victory, and even though I still have a ways to go, it gets better and easier every day. Remember to stay strong and always hold yourself in a place of loving and care.
I have a ~1000mW green laser that i tried shining through a prism by firing it ~perpendicular to the angled side so that it reflects internally off of the base.
What i noticed was that within the prism, the beam looks completely red. On exiting it's green as well.
Question being: why does the beam turn red inside the prism?

Update: same prism under a UV light and a white LED torch. I think the white LED torch is also showing a faint red beam inside the prism. https://imgur.com/a/cSXqjeM
Update 2: no visible beam when i shone a red laser through it.
I think the red laser observation adds some credibility to the fluorescence theory. Some impurities reacting to the green wavelengths.
I havenโt ever personally done it and it looks like most mobile laser welds can only effectively fuse materials just under 1/4 inch.
I feel like people have said the same thing about stick when wire feed came out but I still use both stick and wire feed. Will this change in the future? Will arc welding be considered a thing of the past?
