8 Save as.stl File

9 What is an STL File? Standard tessellation/triangulation language is a 3D file format which uses a series or triangles to describe the outer surfaces of a 3D model. Industry standard. There is no color, texture or additional attributes i.e. features. You can improve the resolution or accuracy by selecting Options and changing the settings. Dassault Systems

10 SolidWorks STL Settings (Options) Binary files are smaller. Deviation is expressed as a linear dimension and refers to the maximum distance that the facet of the.stl file is permitted to be away from the original geometry. Angle refers to the angular deviation allowed between adjacent triangles, Dassault Systems

11 Resolution Settings Ideal Too Course Optimal File to Large The optimal setting is going to be printer dependent, and requires some experimentation. Dassault Systems

35 Advantages of Bioprinting Anatomically correct constructs from medical imaging data. Porous structures. Co-culturing of multiple cell types. Precise patterning of cells and ECM. Controlled deliver of growth factor and genes. Potential for high-throughput fabrication. Suitable vascularization - eventually! Remember the need for a vascular network in relationship to the diffusion length of oxygen.
