test using the most effective dressing showed the positive effect of 3D-printed porous pattern on wound healing, including faster wound closure, regenerated hair follicles, and non-traumatic dressing removal compared to the non-printed hydrogel with the same composition and the standard of care. Results from this research showed that 3D-printed dressings with an adequate gelatin: alginate ratio enhanced wound healing activity for up to 7 days of moisture retention on deep PTB wounds.
