Abstract

A method of reproducing a biological object includes 3D-imaging the object and generating a mold using a 3D printer; obtaining cells from a donor site on the object; preparing a live cell suspension using the cells from the donor site; forming a scaffold in the mold with collagen and seeding the scaffold with live cells, growing the cells in the mold and curing the collagen; and surgically implanting the object into a living subject, where the cells continue to live in the living subject.

First claim

What is claimed is:

1 . A method of reproducing a biological object, comprising:
3D-imaging the object and generating a mold using a 3D printer; obtaining cells from a donor site on the object; preparing a live cell suspension using the cells from the donor site; forming a scaffold in the mold with collagen and seeding the scaffold with live cells, growing the cells in the mold and curing the collagen; and surgically implanting the object into a living subject, where the cells continue to live in the living subject.

2 . The method of claim 1 , comprising auto-grafting a three-dimensional irregularly-shaped object.

3 . The method of claim 1 , comprising printing a quantity of harvested skin cells.

4 . The method of claim 1 , comprising forming a photocrosslinkable interpenetrating polymeric network (IPN) of collagen and hyaluronic acid (HA).

5 . The method of claim 1 , comprising printing a bone fragment.

6 . The method of claim 1 , comprising printing materials with nerve tissues.

7 . The method of claim 1 , comprising printing materials with brain cells, lung cells, pancreatic cells or stem cells.

8 . The method of claim 1 , comprising injecting bio-materials using a syringe in the pen or spraying a mist of the bio-materials using a MEMS actuator.

9 . The method of claim 1 , comprising printing a skin, a nose or ear portion.

10 . The method of claim 1 , comprising transmitting the target area image to a remote medical professional for modification prior to printing.

11 . A method of healing a skin wound includes
imaging the skin wound using an imager including a supply cartridge; obtaining dermal cells from a donor site; preparing a live cell suspension using the dermal cells from the donor site and insert the supply cartridge with the live cell suspension into the pen; 3D printing onto the wound region an acellular dermal matrix (ADM) scaffold with collagen and seeded with live cells processed from the autologous graft; and securing with sutures and covering with a suitable bandage.

12 . The method of claim 11 , comprising auto-grafting a three-dimensional irregularly-shaped object.

13 . The method of claim 11 , comprising printing a quantity of harvested skin cells.

14 . The method of claim 11 , comprising forming a photocrosslinkable interpenetrating polymeric network (IPN) of collagen and hyaluronic acid (HA).

15 . The method of claim 11 , comprising surgically implanting the object into a living subject, where the cells continue to live in the living subject.

16 . The method of claim 11 , comprising printing materials with nerve tissues.

17 . The method of claim 11 , comprising printing materials with stem cells.

18 . The method of claim 11 , comprising injecting bio-materials using a syringe in the pen or spraying a mist of the bio-materials using a MEMS actuator.

19 . The method of claim 1 , comprising printing a nose or ear portion.

20 . The method of claim 11 , comprising transmitting the target area image to a remote medical professional.
