be made in a set period of time. Build rates, or production rates, for additive
manufacturing (AM) are considerably slower than traditional manufacturing.
Cables - ANSWER Bundled wires in a protective sheath that are used to transfer
telecommunication signals. Cables are used to connect computers in a network.
Continuous Liquid Interface Production - ANSWER CLIP. An additive manufacturing
(AM) process in which a part is built by curing layers of a photopolymer with an
ultraviolet (UV) projector. In continuous liquid interface production, the part is drawn out
of the vat as the UV projector creates an entire layer in one flash of light.
Cures - ANSWER Causes a material to bond and solidify through heat, time, or
chemical means. A laser cures photopolymers in vat photopolymerization processes.
,G-Code - ANSWER An additive-manufacturing (AM) compatible file that provides
detailed instructions to an AM machine. G-code includes information about the exact
shape and size of each layer.
Hinges - ANSWER A mechanical joint that is capable of movement. Hinges can be
created as a single integrated part using additive manufacturing (AM) technology.
Hole Proximity - ANSWER The location of a hole relative to the edge of a part. Proper
hole proximity ensures that the hole is far enough away from the edge of a part to
maintain the correct shape.
Isopropyl Alcohol - ANSWER A colorless, flammable chemical compound with a strong
odor used to clean and sterilize surfaces. Isopropyl alcohol is often used to clean plastic
parts made using vat photopolymerization processes.
Markup Language - ANSWER A system that encodes information in a document or
computer file by clearly separating that information from the original document or
computer file. Markup language is used in advanced additive manufacturing files (AMF)
to allow engineers to add more specificity and complexity to a part design.
Networking - ANSWER The ability for two or more computers to connect and
communicate with each other. Networking additionally allows computers to
communicate with additive manufacturing (AM) machines.
Production Rate - ANSWER The time it takes to build a part or the number of parts that
can be made in a set period of time. Production rates, or build rates, for additive
manufacturing (AM) are considerably slower than traditional manufacturing.
Production Speed - ANSWER The time it takes to turn a workpiece from raw material or
stock into a finished part. Traditional manufacturing operations typically have better
production speed than additive manufacturing.
Raw Material - ANSWER An unprocessed or lightly-processed component used to
make the finished part. Raw materials in manufacturing include metal, plastic, and
ceramic.
Resins - ANSWER A type of fluid plastic that cures and hardens when exposed to light.
Resins, or photopolymers, appear to be liquids but are technically viscous solids and
are used in material jetting and vat photopolymerization.
Ribs - ANSWER A structural component that provides shape and support. Ribs are
used to reinforce a thin section of a part, such as a wall.
Shell - ANSWER The outer layer of an additive manufacturing (AM) part. Shells can
vary in thickness at different places on an individual part.
,Slicer - ANSWER A computer program that divides an STL file into layers for additive
manufacturing (AM). Slicers, or slicing programs, can either be separate computer
programs or part of the machine interface.
Small-Batch Production Runs - ANSWER The production of a limited number of parts,
usually less than 500. Small batch production runs can be cost-effective using additive
manufacturing (AM) technology.
Support Structure - ANSWER A reinforcing component used to hold the weight of an
additively manufactured part as it is being constructed. Support structures are removed
from the part once the build is complete.
Tandem - ANSWER Acting together or in conjunction with another object. Tandem
nozzles are used in 2 x 1D channel construction to create a part layer more quickly than
1D channel construction.
Thermosets - ANSWER A group of polymers that are permanently hardened by heating.
Thermosets have high rigidity and thermal stability.
UV Projector - ANSWER A device that creates a two-dimensional layer of ultraviolet
(UV) light. UV projectors are used to create an entire part layer in a single moment in
continuous liquid interface production processes.
Wireless Router - ANSWER A signal-producing device that transmits data through an
antenna rather than a network cable. Wireless routers, which are used to create
computer networks, operate through the use of radio waves.
Absorbent Material - ANSWER A substance that can draw in and hold a large amount of
liquid. Absorbent materials are used to clean chemical spills to help ensure that the
chemical is completely removed from the area or surface.
Adapters - ANSWER A device that converts alternating current to direct current or
connects incompatible electrical sources and devices. Adapters should not be used with
additive manufacturing machines because they lead to electrical hazards.
Air Filtration Unit - ANSWER A ventilation component containing a mesh fiber or other
medium to remove harmful components from the atmosphere. Air filtration units are
used in a variety of ventilation systems, including personal respirators and general
ventilation setups for a work area.
Airbrushing - ANSWER A painting process that uses an air-powered device that turns
the paint into a fine mist. Airbrushing quickly creates a thin, even coating of paint.
Antistatic Footwear - ANSWER A shoe or shoe covering made of material that resists
the flow of electricity. Antistatic footwear helps prevent operators from building up static
charge or serving as a conduit for electricity.
, Aprons - ANSWER Protective clothing that is tied on to protect the torso and upper legs.
Aprons are usually used to provide extra protection when working with hazardous
liquids.
Band Saw - ANSWER A cutting device that uses a serrated blade constructed from a
continuous loop or band of metal. Band saws are used in additive manufacturing post-
processing to remove metal parts from build plates.
Blocks - ANSWER Any device used to lock a machine component in place. Blocks are
used when a machine component can still move even if it is not energized.
Build Chambers - ANSWER The area contained within the additive manufacturing
machine where the part is actually built. Many build chambers are enclosed to improve
the safety of the manufacturing operation.
Build Plate - ANSWER The removable platform in an additive manufacturing system
that supports the in-process part. A build plate is commonly used in metal powder bed
fusion operations.
Cancer - ANSWER Malignant cell growth that surrounds and invades healthy tissue.
Cancer can be caused by prolonged exposure to infrared (IR) and ultraviolet (UV)
radiation.
Chemical Baths - ANSWER A specialized solution that an operator dips an additively
manfuactured part into in order to remove support structures. A chemical bath is
formulated to dissolve support structures without harming the part.
Circuits - ANSWER A completely enclosed electrical path consisting of various devices
that transmit or control electricity. Circuits are used in computers and automated
manufacturing equipment, such as additive manufacturing machines.
Class-D - ANSWER A type of fire extinguisher rated for putting out fires caused by
combustible metals. Class-D fire extinguishers use dry powder to put out fires.
Contact Burns - ANSWER Skin damage from touching an overheated component or
other object. Contact burns can occur when poor electrical connections cause an
exposed device or component to dangerously overheat.
Coveralls - ANSWER Protective clothing that covers the entire body from the wrists to
the ankles. Coveralls provide good general protection for the skin against hazards like
skin irritants.
Dedicated Circuit - ANSWER A power supply that is used for a single device that
requires a large amount of electricity. Dedicated circuits are used with additive
