They used a combination of conventional machining with electroplating, in a really clever technique to mimic what we can do with 3D printing nowadays. 🥰 CONSIDER SUBSCRIBING 🥰 🔬Patreon if that's your jam: https://www.patreon.com/breakingtaps 📢Twitter: https://twitter.com/BreakingTaps 📷Instagram: https://instagram.com/breakingtaps 💻Discord: https://discord.gg/R45uCXcEv4 -------------------------- 📚 Sources!
