なぜ 405 nm Is the Standard Wavelength for Resin 3D Printing?
Resin 3D printing depends on precise light-driven chemistry, but the wrong wavelength can cause slow curing and unstable printing. Many early systems struggled with this mismatch. 405 nm became the standard wavelength for resin 3D printing because common photoinitiators absorb strongly in the violet region, enabling efficient polymerization while remaining compatible with affordable semiconductor light […]
