A 3D-printed recycled-PET CPAP mask shows no detectable penalty in surface bioburden, pressure tolerance or particle transfer relative to a commercial interface

It presents a comparative, matched-pair bench assessment of a fused-deposition-modelled, recycled-polyethylene-terephthalate continuous positive airway pressure mask against a commercially manufactured reference interface. The investigation examines three prespecified endpoints:...

From Regional Evidence to National Implications: Life Cycle Assessment of Pulp–Paper Production Modes, Collaborative Strategies, and Energy Transition in China
