A study produced by four research institutions in Brazil combines two 3D printable polymers into structures ideal for cell-growth. Known as cell scaffolds, these structures are used in regenerative medicine; i.e. repairing the damage to human organs by using the body’s own cells.
PCL is commonly used in 3D printing as it is biodegradable and has a low melting point. PLGA is a copolymer often used to make medical devices. Both plastics are approved for non-toxic compatibility within the body by the FDA.
In this study, 3D printed PCL is coated with PLGA using an electrospinning technique. The benefit of electrospinning is that it doesn’t require high temperatures to control a liquid polymer. It also blocks any harmful solvents from entering into a finished object.
