I haven't heard of 3Teeth before, but to be honest most of my industrial & techno metal (I don't like making much of a distinction here) experience comes from the 90s and early 2000's. While I would love to find new bands stomping through the genre, it doesn't seem to be a very popular one, or at least nothing has made a connection for me in a while. Perhaps I should make a more concerted effort to look and see what's popped up in the last ten years.
Anyway, my all time favorites songs and albums tend to come from the following bands, many of them I'm sure you're familiar with. Oh, and one last thing: many of these bands might only have one album that would qualify as techno/industrial metal, while the rest of their catalog veers off towards one direction or another (or completely different genres in a couple cases), but either way, I enjoy what they've contributed in this style:
Die Krupps. These guys have been around forever, but never made a huge splash in the U.S. Outstanding tracks would include To The Hilt (remix version from Rings of Steel), Iron Man (not a cover of Black Sabbath), A Cover of Metallica's One. I don't care if people hate the 1992 Die Krupps remixes of Metallica classics, all of them work for me and I enjoy them for wholly different reasons than the classics they draw inspiration from.
Shotgun Messiah: Violent New Breed. This is more or less a solo album by Tim Skold, from KMFDM & Marylin Manson. Until this album, Shotgun Messiah's back catalog is best described as hair metal, and best avoided. But this album is phenomenal.
Mindless Self Indulgence. The faster and maniacal the better as far as I'm concerned. I don't know a whole lot about this band, but I own a couple albums and they play hyper industrial & techno-infused pop-rock and pop-metal. I typically prefer more aggressive stuff, but spastic works just fine for me too. Examples: Tom Sawyer (Rush cover), What Do They Know.
Professional Murder Music. Bought a physical copy of this album back in 2000 for no other other reason than I liked the name of the band and was curious to see what they sounded like. Turned out to be worth the money at the time.
Sybreed: Posthuman Manifesto (at times these guys sound like they want to be Fear Factory, but they aren't nearly as consistent. Still some great tracks though).
Bands I'm sure you've heard of already:
White Zombie: Astro Creep 2000 (earlier albums were geared more towards sludge and groove metal, with La Sexorsisto being the only one I find wholly listenable and enjoyable aside from Astro Creep).
Static-X: The best albums from them would include Wisconsin Death Trip, Start a War, and Machine. Examples: I'm With Stupid, Love Dump.
Fear Factory (as mentioned by Armando) Probably tied with Static X as my favorite band on the list, partly due to the sheer size and appeal of their catalog. God Eater. Obsolete. Demanufacture.
Nine Inch Nails (the Broken EP specifically. It's much more industrial metal than anything else NiN has done). Happiness in Slavery. Yea, I know. Everybody probably own this if they already listen to NiN (who doesn't?), but the album is well over twenty years old, and for all I know newer fans might not have even gone back that far.
Another thing the 90s was known for was a shit ton of Industrial Remixes of metal songs. But most of my favorites are one-offs or b-sides from sources too wide-spread and varied to make an exhaustive list. But it was a great time if you wanted to hear weird shit like Trent Reznor fucking around with Megadeth tracks etc.
I mean, shit. Even Danzig dipped a toe into the genre for one album, Blackacidevil. Hand of Doom (Sabbath cover), Blackacidevil. This album isn't nearly on par with the first four albums from the band, but I can't say I haven't turned it the fuck up and blasted it hundreds of times over the years. And while I understand why some people think certain artists should stick to what they're good at, I think the album is under-appreciated, and several of the tracks kick ass. Even if it did more or less herald the end of an era for Danzig as we knew it.
Also, if you haven't heard it yet, you might enjoy the Spawn Soundtrack, which is one giant techno/industrial metal-remix fuckfest. One Man Army (Prodigy & Tom Morrelo). No Remorse (Slayer & Atari Teenage Riot).
