Traditional methods of making 3d scaffolds
Splet09. apr. 2024 · What is 3D-printing? 3D printing or additive manufacturing is a process of making three-dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process, an object is created by laying down successive layers of material until the object is created. Each of these ... SpletA well-established approach for 3D cell culture is to grow cells on structural scaffolds, typically composed of biopolymers that are arranged to mimic the physiological extracellular matrix (ECM). These scaffolds are usually designed as inserts that can be conveniently included into conventional cell culture workflows.
