In sintering, a part that is made of powdered material that has been compressed and held together with a binding material. A green part is delicate. It is heated and/or chemically treated to remove the binding material, producing a brown part.
A form of abrasive blasting where small angular particles are propelled through a nozzle with compressed air to smooth a rough surface. More aggressive than bead blasting because of the use of hard material with angular shapes.
A material property of a thermoplastic that is used to understand the impact of temperature on the flexibility of the material. In additive manufacturing, once a part cools to below the heat deflection temperature it is safe to handle.
A group of processes used to alter the physical properties of a material. In additive manufacturing, it refers to using heat to relieve residual stresses. It can also be used to increase the strength or hardness of the metal by modifying the microstructure of the material, and there fore changing the macro properties.
In FDM/FFF, the portion of the head where the filament is heated from room temperature to the printing temperature.
A vendor-neutral file format for CAD data known as Initial Graphics Exchange Specification (IGES). Created in 1976, IGES became an ANSI standard in 1980. The standard was last modified in 1996 and has been replaced by the ISO STEP standard in many cases. Almost all CAD tools output IGES. It uses the .igs or .iges […]
A gas that does not chemically react with other substances. Most commonly Nitrogen and Argon. Can be made from an element (noble gasses) or a compound of several elements. Used in additive manufacturing to create an atmosphere in the build chamber or inside a material storage container that is free from oxygen to avoid oxidation, […]
A cellular or lattice structure used to fill the volume of a part with something other than solid material. Usually, a 2D repeated pattern extruded in the build direction. An infill reduces material use and weight of parts while keeping strength.
A liquid deposition process that propels (jets) very small droplets of material from a print head onto a surface. Many small jets are arranged on the printhead to deposit larger amounts of material at the same time and can be turned on and off to create a pattern. When multiple heads with different materials in […]
A chemical bond of one polymer chain to another.
The temperature at which a temperature cured polymer resin cross-links to form a hard material.
A chemical process where the molecules in a liquid resin cross-link to create a hard polymer. Many additive manufacturing processes use the curing process to convert a liquid to a solid on a given layer. Curing can be caused by light in a photopolymer, heat, or time.
A plane, axis, or point on an object that is used as a reference location for measuring distances or angles to other features on the object and the tolerance of those distances or angles.
A device that is used to remove binding material from a part. Heat or chemicals are usually used.
When the layers of an additive manufacturing part separate from one another.
