Bambu H3C/P3C Can Do WHAT? Mixed Nozzle Sizes + P3C AMS Leak

Different nozzle sizes in ONE print? Bambu Lab’s latest H3C announcement could mean fine detail and faster infill in the same part. Plus: new 2.85 mm TPU 75A filament and leaked AMS 3P images that raise questions about the upcoming P3C. In this Bambu Lab news update, I explain why combining 0.2 mm and 0.4 mm nozzles matters for multi-nozzle 3D printing—and explore the potential of using a small nozzle for detailed outer walls and a larger nozzle for infill. We also look at why Bambu is using 2.85 mm filament for super-soft TPU, how filament diameter affects feeding, and what the apparent bypass function in the leaked AMS 3P photos might mean for flexible materials. The H3C announcement and the AMS leaks are separate stories: the leaked photos remain unverified, and my interpretation of the bypass feature is speculation.
