The new 3MF file format supports which of the following
characteristics of a model:
❖Color & material type, Curved triangles, Instancing of
structures like unit cells, are all supported in 3MF
You friend shows you this statue that someone 3D printed
and wants to know what 3D printing process was used to
make it. It is full, continuous color and has a granular
surface. It's fairly heavy because it seems to be solid
material, not hollow. (Wedding)
❖Binder Jetting
,Page 2 of 65
Photospeed is...
❖A measure of how quickly a photopolymer cures
An Andrew Number is...
❖A measure of applied energy density in powder bed
fusion printing
Which of the following structures would be the toughest
(as in its structural material property)?
❖BRICK
One of your colleagues is asking you how to get good
bonding between layers in a photopolymer process. Of
course you want to give good advice, so you say...
❖Make sure your cure depth is about 30% greater than
layer thickness
,Page 3 of 65
When testing bending stiffness of a 3D printed ceramic
object which type of testing is best?
❖4-point bending
Which AM process is most often used to enable variable
metallurgy of custom metal alloys and functional grading
of material properties within a single part
❖Directed energy deposition
Which type of sintering is characterized by the
coalescence of powder particles of more than one
material, without full melting?
❖Indirect processing, liquid phase sintering, and
chemically inducing sintering
, Page 4 of 65
Consider photopolymer Working Curves A and B in this
figure. Which photopolymer will polymerize at a lower
exposure
❖Steeper Slope boi
Of the following, which Am process is mot often used to
create production parts that have more than one material
in a single part (i.e. NOT one material in each of multiple
parts of a build)?
❖Powder bed fusion - indirect processing
❖You are making a photopolymeric part for a paying
customer and you run out of material. So you buy
some replacement material. You want to be
completely certain the new material will perform
exactly the same as the prior material you were
