Computer Aided Design = includes all the software and geometric modeling techniques used to design, virtually test and produce manufactured products and the tools to manufacture them.
Grain measurement unit for a grained surface of an object.
Layer thickness measures the height of each material addition in additive manufacturing or 3D printing processes based on stacking layers.
FABrication LABoratory = community digital fabrication workshop open to all (tinkerers, designers, artists, students, hackers, …). It is equipped with machines controlled by computer and must respect a charter put in place by MIT.
Manufacturing process by adding material, most of the time computer-assisted.
Fused deposition modeling : mechanical deposition of plastic material in successive layers. The machine deposits a molten plastic wire through a nozzle.
Electronic file representing a three-dimensional object. It is designed by 3D modeling to allow the printing of the desired object with a 3D printer. The creation of 3D files is done by CAD.
Glass filled: material loaded with glass fibers.
Mineral Fiber Filled : material loaded with mineral fibers.
Additive manufacturing process. Here are some technologies that coexist: FDM, SLA and Selective laser sintering…
Machine intended for the production of 3-dimensional parts, by depositing successive layers of molten material.
Partial or complete representation of an object (existing or planned) in order to test and validate certain aspects. The model can be produced on a given scale, most often reduced or enlarged to facilitate viewing.
Object obtained by 3D modeling.
Stage in three-dimensional computer graphics which consists of creating, in 3D modeling software, a three-dimensional object, by adding, subtracting and modifying its constituents.
Multi Jet Fusion
Polyamide: polymer plastic.
Poly-Carbonate: polymer plastic.
High Density Poly-Ethylene: polymer plastic.
Material that reacts on contact with light radiation.
A chemical reaction or process by which small molecules react with each other to form molecules of higher molecular weights.
Poly-Propylene: polymer plastic.
Computer-controlled manufacturing method, which brings together a set of tools, which, arranged together, allow to achieve intermediate representation projects of product design: models, prototypes and pre-series.
An original model that has all the technical qualities and all the operating characteristics of a new product, but it is also sometimes an incomplete example of what a product could be.
Reaction Injection Molding = By creating an epoxy or silicone resin mold (previously from a master model made in Stereolithography) a prototype can then take shape.
StereoLithography Apparatus : polymerization of a photosensitive epoxy resin by ultraviolet laser, in layers of 0.10 to 0.15 mm.
Selective laser sintering : polyamide particles are agglomerated by a CO2 laser.
