CSWA-AM Questions with Detailed Verified
Answers
Additive Manufacturing Ans: The process of joining materials to create
an object from a 3D model, usually adding layer over layer
What 3D areas is technology for 3D printing advancing? Ans: Printers
and printing methods, design software, and materials
What is additive manufacturing sometimes known as? Ans: rapid
prototyping
FFF or FDM Ans: Fused Filament Fabrication or Fused Deposition
Method
What is FFF technology used for Ans: Desktop 3D printing
What is the purpose of a slicer Ans: Takes a 3D model and translates it
into individual layers
What is an STL file? Ans: Stereo lithography file format, commonly used
in 3D printing
What is SLA Ans: a form of 3D printing in which a computer-controlled
low power highly focused ultraviolet laser is used to create layers from a
liquid polymer that hardens on contact.
List some advantages of FFF Manufacturing Ans: Lower Cost, Lowers
barriers to traditional subtractive manufacturing, reduce part count in an
assembly, numerous thermoplastic filament types and colors, remote
monitoring ability, print multiple filaments, customize percent infill, uses
, Page | 2
only the material amount required, no post curing process, faster
development cycle, quicker customer feedback, quicker produce
customization and configuration, open source filament, parallel verticals,
open source slicing engines
List some advantages of FFF manufacturing Ans: Slow build rates, may
require post-processing, poor mechanical properties, calibration required,
print time, requires a CAD model
After printing something using an SLA 3D desktop printer what should
you wash the print in? Ans: Isopropyl Alcohol(IPA)
What are a few advantages of SLA manufacturing Ans: stronger final
parts, parts are watertight and fully dense, high resolution
what are a few disadvantages of SLA manufacturing Ans: higher cost,
material cost, slower fabrication speed, not suitable for big parts, prints
only a single material type, requires an isopropyl alcohol wash, ability to
safely dispose the use of isopropyl alcohol, requires a post-cure, sensitive
to UV light exposure, may need a drain hole
What does SLS stand for? Ans: Selective Laser Sintering
What is the most common technology for additive manufacturing? Ans:
SLS
What is SLS? Ans: fuses particles together layer by layer through a high
energy pulse laser. This process starts with a tank full of powder. As the
print continues the bed lowers itself for each new layer.
What materials can be fused using SLS? Ans: both metal and plastic
making them stronger and more durable
Which 2 manufacturing techniques are the most precise? Ans: SLA and
SLS
What does PLA stand for Ans: polylactic acid
