Today wearables are separate devices that users must remember to wear. The next step forward will be to integrate these devices into our clothing.
A key step towards realizing wearable devices in clothing is creating displays that can be integrated into textiles to allow interaction with the wearer. earable devices allow people to monitor their fitness

The goal of integrating different material and structural properties within printed objects has demanded the invention of new, flexible printing platforms.
For example, to print a functional"wearable"device including its electronic components, a 3d printer would need to seamlessly transition from the flexible material that moves with the wearer joints to the rigid material that holds the electronic components.
It would also need to embed electrical circuitry with multiple inks of varying conductivity and resistivity,
