Abstract
Official abstract text for this publication.
A liquid composition for producing a self-destructible temporary structure by additive manufacturing is provided. The liquid composition includes a biosynthetic copolymer as a degradable component and an enzyme as a disintegrating agent, the disintegrating agent is capable of disintegrating the degradable component, wherein after exposure to an external trigger, the disintegrating agent gradually degrades the degradable component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A 3-dimensional self-destructible temporary structure for supporting an object during a layer-by layer printing process, the structure comprising: hydrogel layers, wherein each hydrogel layer comprises a polymerized copolymer, and enzyme which is capable of disintegrating the polymerized copolymer, wherein the hydrogel layers form a 3-dimensional self-destructible temporary structure. 2. The 3-dimensional self-destructible temporary structure of claim 1 , wherein the copolymer comprises a protein or a peptide. 3. The 3-dimensional self-destructible temporary structure of claim 1 , wherein the copolymer comprises any one or more of poly(ethyleneglycol) (PEG), poly(acrylic acid), poly(hyaluronic acid), poly(caprolactone) or poly(vinyl alcohol). 4. The 3-dimensional self-destructible temporary structure of claim 1 , wherein the enzyme is an esterase, a trypsin, a collagenase, a cellulase or a dextranase. 5. The 3-dimensional self-destructible temporary structure of claim 4 , wherein the esterase is lipase. 6. The 3-dimensional self-destructible temporary structure of claim 1 wherein the enzyme is encapsulated by nanoparticles. 7. The 3-dimensional self-destructible temporary structure of claim 1 , wherein the layers of self-destructible temporary structure are formed by inkjet printing. 8. The 3-dimensional self-destructible temporary structure of claim 1 , wherein the enzyme comprises hydrogel particles that gradually release enzyme by diffusion.
