Personalized Continuous Glucose Monitors andSensors

Continuous glucose monitoring (CGM) sensors tradionally rely on adhesive patches that can cause discoult or allergic reactions over extended wear. 3D printing offers a solution by sensor housings with explicble, porous structures that allow better airflow and reduce skin maceration.

Technological Advances Enabling Remote Care

Digital Twins andVirtual Prototyping

Te koncept of a digital twin - a virtual rephela of a patient 's anatomy or device - is central to modern 3D printing workflows.
