Sustainable medical materials printed by melt electrowriting: A mini-review

The development of melt electrowriting (MEW) technology can print many sustainable medical materials into high-resolution scaffolds to be applied in tissue engineering and regenerative medicine. The printability of the MEW can be highly improved after tuning and avoiding the particular phenomena of jet lag, fiber shifting, jet pulsing, and fiber bridging. Different MEW devices are developed to produce scaffolds with complicated or hierarchical structures to mimic human tissues. It is believed that the MEW technology can be extended to many other medical applications in the following years.
