Infill: Printing solid objects requires a significant amount of material (such as filament) and time. To mitigate this, slicers can automatically convert solid volumes to hollow ones, thereby saving costs and reducing print time. These hollow objects can be reinforced with internal structures, like internal walls, to enhance robustness.
STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.
In 2007, new features were added to the viewer: an editor and a converter. The application got a full set of editing tools for design and project work. As a converter, ABViewer made it possible to convert selected parts of the image. ABViewer 6 was available in three versions (Standard, Professional and Enterprise). [6]
Solid modeling (or solid modelling) is a consistent set of principles for mathematical and computer modeling of three-dimensional shapes . Solid modeling is distinguished within the broader related areas of geometric modeling and computer graphics , such as 3D modeling , by its emphasis on physical fidelity. [ 1 ]
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
PDES was designed to completely define a product for all applications over its expected life cycle, including geometry, topology, tolerances, relationships, attributes, and features necessary to completely define a part or assembly of parts. PDES can be viewed as an expansion of IGES where organizational and technological data have been added.
One of the advantages of stereolithography is its speed; functional parts can be manufactured within a day. [10] The length of time it takes to produce a single part depends upon the complexity of the design and the size. Printing time can last anywhere from hours to more than a day. [10]
