3d Printing And Its Effects On The World Of Tissue...

3D Printing On the forefront of tissue scaffold fabrication is 3D printing. 3D printers have a multitude of advantages over traditional scaffold fabrication methods. High print precision allows fibers to be deposited into 3D structures with finely tunable dimensions, 3D printers also have the ability to incorporate multiple materials into the same structure through multiple extrusion heads. Jakus et al. used a 3D extrusion based printer to create a graphene and polylactide-co-glycolide scaffold and showed it could create a 3D graphene structure (3DG) with features as small as 100 um and as large as 10cm offering a large range of applications. They also showed that 3DG supports human mesenchymal stem cell (hMSC) adhesion, viability, proliferation, and neurogenic differentiation with significant upregulation of glial and neuronal genes [9]. The ease in fabrication and the ability to precisely modify structure with 3D printers allows for opportunities in a wide range of tissue engineering applicat ions. Incorporating growth factors and other bioactive molecules into a CP It is often desirable to modify the material properties of a polymer to better optimize it for different applications. Critical properties that affect the possible applications of the polymer include conductivity, porosity, hydrophobicity, degradability. There are four main processes to incorporate chemical and biological molecules into a polymer. The simplest method is adsorption, following theShow MoreRelatedThe Use Of Nano Structured Neural Scaffolds For Neural Regeneration2741 Words   |  11 PagesTopical Review Use of nano-structured neural scaffolds for neural regeneration in case of Parkinson’s Disease ABSTRACT Parkinson’s Disease (PD) affects a large percentage of people all over the world. Currently, an effective strategy for regeneration of neurons that are lost in PD does not exist; however, nanotechnology has offered new avenues in the field of neural tissue regeneration. Nanostructured scaffolds have been shown to have the ability to promote neuronal growth and their excellent biomimeticRead MoreCurrent And Projected Healthcare Applications Of 3d Printing Essay3058 Words   |  13 PagesIntroduction Three-dimensional (3D) printing, also known as rapid prototyping (RP) and additive manufacturing (AM), is a transformational technology that is anticipated to revolutionize the healthcare industry.
