3D printed impact resistant glove
A protective garment includes a base layer formed from a flexible material. A grip layer is disposed on a first side of the base layer. The grip layer has an increased coefficient of friction compared to the base layer. A protective layer is disposed on a second side of the base layer. The protective layer includes a three-dimensional matrix that has a plurality of columns that extend in a first direction and a plurality of rows stacked on the plurality of columns that extend in a second direction. The plurality of rows and the plurality of columns define a plurality of voids.
1. A protective garment, comprising:
a base layer formed from a flexible material;
a grip layer disposed on a first side of the base layer, the grip layer having an increased coefficient of friction compared to the base layer; and

a plurality of columns extending in a first direction; and
a plurality of rows stacked on the plurality of columns and extending in a second direction, wherein the plurality of rows and the plurality of columns define a plurality of voids.
2. The protective garment of claim 1 , wherein the three-dimensional matrix defines feet coupled to the base layer, a lower wall extending between the feet, and an upper wall extending over the lower wall.
3. The protective garment of claim 1 , wherein the protective layer is constructed of Thermoplastic Polyurethane.
4. The protective garment of claim 1 , wherein the protective layer has a density of less than 1 g/cm 3 .
5. The protective garment of claim 1 , wherein the protective layer has a moisture vapor transmission rate in a range of from 0.003 mL/cm 2 /hour to 0.01 mL/cm 2 /hour.
6. The protective garment of claim 1 , wherein the protective layer is configured to reduce transmitted force by approximately 56% to 90%.
7. A protective glove, comprising:
a base layer formed from a flexible material, the base layer having an anterior side and a posterior side;
a grip layer disposed on the anterior side of the base layer, the grip layer having an increased coefficient of friction compared to the base layer; and
a protective layer disposed on the posterior side of the base layer, the protective layer defining a three-dimensional matrix including a plurality of print layers, wherein the plurality of print layers defines feet coupled to the base layer and at least one wall extending between the feet and spaced-apart from the base layer.
8. The protective glove of claim 7 , wherein each of the plurality print layers includes at least one of a plurality of columns and a plurality of rows, and wherein each of the plurality of rows and the plurality of columns are spaced 3 mm apart and have a thickness of 1.2 mm.
9. The protective glove of claim 7 , wherein the at least one wall includes a lower wall and an upper wall extending over the lower wall.
10. The protective glove of claim 9 , wherein the plurality of print layers defines a support extending between the lower wall and the upper wall.
11. The protective glove of claim 7 , wherein the plurality of print layers defines an absorption member extending from a surface of the at least one wall.
12. The protective glove of claim 7 , wherein the protective layer extends over a metacarpal region of said protective glove.
13. The protective glove of claim 7 , wherein the protective layer extends over a primary region proximate a proximal phalanx region, middle phalanx region, and distal phalanx region of at least one finger area of said protective glove.
14. The protective glove of claim 13 , wherein the protective layer is disposed over a secondary region proximate a proximal phalanx region and distal phalanx region of a thumb area of said protective glove.

16. A method of manufacturing a protective glove, comprising:
constructing a base layer of a flexible material;
attaching a grip layer to a palm area of the base layer; and
printing a three-dimensional protective layer for a dorsal region of the base layer, the printing comprising:
printing a first pattern onto the base layer; and
printing a second pattern onto the first pattern, wherein the second pattern is different from the first pattern.
17. The method of claim 16 , wherein the step of printing the three-dimensional protective layer includes:
printing the three-dimensional protective layer directly onto the base layer at selected locations.
18. The method of claim 16 , further comprising:
removing the three-dimensional protective layer from a carrier; and
adhering the three-dimensional protective layer to the dorsal region of the base layer.
19. The method of claim 16 , further comprising:
tuning the three-dimensional protective layer in all three dimensions to produce selected properties.
