Composite biodegradable polymeric based material, a product and a method of making same

Abstract

Disclosed is a composite biodegradable polymeric based material comprising: a biodegradable polymeric matrix; at least 5 wt. % biodegradable plasticizer; and at least 2 wt. % biodegradable filler configured to stabilize the biodegradable plasticizer inside the polymeric matrix.

1 . A method of making a composite biodegradable polymeric based product, comprising:
 mixing together:
 a biodegradable polymeric matrix; 
 at least 5 wt. % biodegradable plasticizer; and 
 at least 5 wt. % biodegradable filler, wherein the biodegradable plasticizer is in a liquid state at a temperature between 10 and 50° C.; and 
 biodegradable filler is present within the composite in an amount sufficient for retaining the biodegradable plasticizer inside the polymeric matrix, and 
   extruding the mixture to form a composite biodegradable polymeric-based filament to be provided to a three-dimensional (3D) printer for printing 3D objects.   
     
     
         2 . The method of  claim 1 , wherein the mixing is conducted in an extruder. 
     
     
         3 . A method of making a composite biodegradable polymeric-based product, comprising:
 mixing together:
 a biodegradable polymeric matrix; 
 at least 5 wt. % biodegradable plasticizer; and 
 at least 5 wt. % biodegradable filler, wherein the biodegradable plasticizer is in a liquid state at a temperature between 10 and 50° C.; and 
 biodegradable filler is present within the composite in an amount sufficient for retaining the biodegradable plasticizer inside the polymeric matrix, and 
   printing a three-dimensional (3D) object from a composite biodegradable polymeric-based filament.   
     
     
         4 . The method of  claim 2 , wherein the mixing is conducted in an extruder.
