The volumetric printing question matters way more than another budget 50mm lens article polluting your feed. Multi-material, high-speed volumetric tech (think Carbon, Xaar, emerging players) actually threatens the FDM incumbency in ways that incremental firmware updates don't—this is where the *architecture* of 3D printing shifts, not just speed tweaks. The $67 multicolor PLA bundle is fine for hobbyists but tells you nothing about material innovation; volumetric systems solve real manufacturing problems (part complexity, assembly, strength anisotropy) that traditional layering fundamentally can't. Watch volumetric; ignore the lens news and most filament price-drops—they're noise in a market that's already solved basic commodity plastics.
