: Recent advances allow for mirrors to be 3D printed using alloys like AlSi10Mg. This method allows for complex internal structures—such as honeycomb or lattice designs—that reduce weight by up to 70% while maintaining high structural rigidity. 3. Performance and Precision Processing

: In some Indian communities, a 500-year-old tradition uses a specific alloy of tin and copper, melted at 1200 degrees and polished with coconut oil. MegaL – Mirror
: Silver is the most reflective across the visible spectrum (reflecting ~95% of light), followed by aluminum (~90%), copper, and gold. 2. Evolution of Manufacturing Techniques
Abstract
The production of metal mirrors has evolved from ancient handcrafted alloys to high-tech vacuum deposition and 3D printing.
: Most modern consumer mirrors are made via "silvering" (chemical deposition of silver on glass) or vacuum deposition of aluminum atoms in a sealed chamber. : Recent advances allow for mirrors to be
Metal mirrors serve as a critical alternative to traditional glass-based optics, offering unique advantages in mechanical stiffness, thermal conductivity, and lightweighting potential. This paper reviews the fundamental principles of metallic reflection, modern fabrication techniques such as additive manufacturing (AM), and their specialized applications in infrared imaging and space telescopes.
