Fiber Bragg gratings are embedded within 3D printed polymer packages. Information about both induced and applied stresses, and operator error, can be determined from the observed spectral shifts and chirping. A novel way to produce packaged broadband gratings, with $\Delta {\lambda _{\rm BW}}\gt {7};{\rm nm/cm}$Δλ>7nm/cm, is proposed and demonstrated.
