3D File Standards IGES Initial Graphics Exchange Specification is a file format which defines a vendor neutral data format that allows the digital exchange of information among Computeraided design

Nonparametric Almost universal format Can be opened by Must include 2D IGES drawings to show any CAD system assembly configuration no IGES assembly files exist STEP Standard for the Exchange of Product Model Data The initial plan was that quotSTEP shall be based on one single complete implementation independent Product Information Model which shall be the Master Record of the integrated topical and application information modelsquot But because of the complexity the standard had to be broken up into smaller parts that can be developed balloted and approved separately In 199495 ISO published the initial release of STEP as international standards with parts that are still used today Consists of several hundred parts and every year new parts are added or new versions of older parts are released This makes STEP the biggest standard within ISO Each part has its own scope and introduction STEP PROS STEP CONS More recent and less problematic than IGES Hundreds of versions of STEP all with when used for complex work different capabilities Can contain assemblies Nonparametric but can be reverse engineered by SolidWorks Parasolids Capabilities include model creation and editing utilities such as Boolean modeling operators feature modeling support advanced surfacing thickening and hollowing blending and filleting and sheet modeling Also includes tools for direct model editing including tapering offsetting geometry replacement and removal of feature details with automated regeneration of surrounding data Parasolid also provides wideranging graphical and rendering

Deposition Modeling CONs Real engineering resins used sturdy parts Slow build Machinable after the fact tapping holes etc Expensive material 25cu inch We have this in BME Slow postprocessing Selective Laser Sintering an additive manufacturing technique that uses a high power laser for example a carbon dioxide laser to fuse small particles of plastic metal direct metal laser sinteringceramic or glass powders into a mass that has a desired 3dimensional shape The laser selectively fuses powdered material by scanning crosssections generated from a 3D digital description of the part for example from a CAD file or scan data on the surface of a powder bed After each crosssection is scanned the powder bed is lowered by one layer thickness a new layer of material is applied on top and the process is repeated until the part is completed Selective Laser Sintering PROS Selective Laser Sintering CONs Looks like a real injectionmolded part Fairly expensive Could cost as much as a machined part Works like a real injectionmolded part depending on the design Laser Cutting a technology that uses a laser to cut materials Works by directing the output of a highpower laser by computer at the material to be cut The material then either melts burns vaporizes away or is blown away by a jet of gas leaving an edge with a highquality surface finish Laser Cutting PROS Laser Cutting CONs Requires
