Additive Manufacturing Terminology Flashcards
3D printer
a machine used for 3D printing
3D printing
the fabrication of objects through the deposition
of a material using a print head, nozzle, or another
printer technology
3D scanning
a method of acquiring the shape and size of
an object as a 3-dimensional representation by recording
x,y,z coordinates on the object’s surface and through software
the collection of points is converted into digital data
additive manufacturing
—a process of joining materials
to make objects from 3D model data, usually layer upon
layer, as opposed to subtractive manufacturing methodologies.
Synonyms: additive fabrication, additive processes,
additive techniques, additive layer manufacturing, layer
manufacturing, and freeform fabrication
additive systems
machines used for additive manufacturing
binder jetting
an additive manufacturing process in which
a liquid bonding agent is selectively deposited to join
powder materials
direct metal laser sintering (DMLS®)
—a powder bed
fusion process used to make metal parts directly from metal
powders without intermediate “green” or “brown” parts;
term denotes metal-based laser sintering systems from EOS
GmbH - Electro Optical Systems. Synonym: direct metal
laser melting
directed energy deposition
an additive manufacturing
process in which focused thermal energy is used to fuse
materials by melting as they are being deposited
facet
—typically a three- or four-sided polygon that represents
an element of a 3D polygonal mesh surface or model;
triangular facets are used in STL files
fused deposition modeling (FDM®)
a material extrusion
process used to make thermoplastic parts through heated
extrusion and deposition of materials layer by layer; term
denotes machines built by Stratasys, Inc
laser sintering (LS)
a powder bed fusion process used to
produce objects from powdered materials using one or more
lasers to selectively fuse or melt the particles at the surface,
layer by layer, in an enclosed chamber
material extrusion
an additive manufacturing process in
which material is selectively dispensed through a nozzle or
orifice
material jetting
—an additive manufacturing process in
which droplets of build material are selectively deposited
powder bed fusion
an additive manufacturing process in
which thermal energy selectively fuses regions of a powder
bed
prototype tooling
molds, dies, and other devices used to
produce prototypes; sometimes referred to as bridge tooling
or soft tooling
rapid prototyping
additive manufacturing of a design,
often iterative, for form, fit, or functional testing, or combination
thereof
rapid tooling
the use of additive manufacturing to make
tools or tooling quickly, either directly, by making parts that
serve as the actual tools or tooling components, such as mold
inserts, or indirectly, by producing patterns that are, in turn,
used in a secondary process to produce the actual tools
rapid tooling
in machining processes, the production of
tools or tooling quickly by subtractive manufacturing methods,
such as CNC milling
reverse engineering
in additive manufacturing, method of
creating a digital representation from a physical object to
define its shape, dimensions, and internal and external
features.
selective laser sintering (SLS®)
denotes the LS process
and machines from 3D Systems Corporation
sheet lamination
an additive manufacturing process in
which sheets of material are bonded to form an object
stereolithography (SL)
—a vat photopolymerization process
used to produce parts from photopolymer materials in a
liquid state using one or more lasers to selectively cure to a
predetermined thickness and harden the material into shape
layer upon layer
stereolithography apparatus (SLA®)
denotes the SL
machines from 3D Systems Corporation
subtractive manufacturing
making objects by removing
of material (for example, milling, drilling, grinding, carving,
etc.) from a bulk solid to leave a desired shape, as opposed
to additive manufacturing
