CSWA-AM QUESTIONS WITH CORRECT
ANSWERS 2026
Additive Manufacturing - CORRECT ANSWER -
The process of joining materials to create an object from a 3D model, usually adding layer over l
ayer
What 3D areas is technology for 3D printing advancing? - CORRECT ANSWER -
Printers and printing methods, design software, and materials
What is additive manufacturing sometimes known as? - CORRECT ANSWER -rapid prototyping
FFF or FDM - CORRECT ANSWER -Fused Filament Fabrication or Fused Deposition Method
What is FFF technology used for - CORRECT ANSWER -Desktop 3D printing
What is the purpose of a slicer - CORRECT ANSWER -
Takes a 3D model and translates it into individual layers
What is an STL file? - CORRECT ANSWER -
Stereo lithography file format, commonly used in 3D printing
What is SLA - CORRECT ANSWER -a form of 3D printing in which a computer-
controlled low power highly focused ultraviolet laser is used to create layers from a liquid polym
er that hardens on contact.
List some advantages of FFF Manufacturing - CORRECT ANSWER -
Lower Cost, Lowers barriers to traditional subtractive manufacturing, reduce part count in an ass
embly, numerous thermoplastic filament types and colors, remote monitoring ability, print multi
ple filaments, customize percent infill, uses only the material amount required, no post curing pr
, ocess, 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 - CORRECT ANSWER -
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? -
CORRECT ANSWER -Isopropyl Alcohol(IPA)
What are a few advantages of SLA manufacturing - CORRECT ANSWER -
stronger final parts, parts are watertight and fully dense, high resolution
what are a few disadvantages of SLA manufacturing - CORRECT ANSWER -
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 a
lcohol, requires a post-cure, sensitive to UV light exposure, may need a drain hole
What does SLS stand for? - CORRECT ANSWER -Selective Laser Sintering
What is the most common technology for additive manufacturing? - CORRECT ANSWER -SLS
What is SLS? - CORRECT ANSWER -
fuses particles together layer by layer through a high energy pulse laser. This process starts with
a tank full of powder. As the printPcontinues the bed lowers itself for each new layer.
What materials can be fused using SLS? - CORRECT ANSWER -
both metal and plastic making them stronger and more durable
