What are the primary printing methods? - ANSWER ✔ :
1. Fused Deposition Modeling
2. Stereolithography
What are some things that can be printed? - ANSWER ✔
: 1. Plastics
2. Biomaterial - skin cells, organ cells, dissolving implants
3. Metals
4. Food
What is a "subtractive" manufacturing process? -
ANSWER ✔ : When the process removes material from
an existing block of material.
What is an "additive" manufacturing process? - ANSWER
✔ : When the process only uses material to make up the
part geometry.
What are some pros of an additive process? - ANSWER
✔ : 1. Less material is wasted
,2. Cost of manufacturing goes down
3. Part is generated in it's final shape
What are two of the leading manufacturing methods? -
ANSWER ✔ : 1. FDM - Fused Deposition Modeling
2. SLA - Stereolithography
What is another type of additive manufacturing process? -
ANSWER ✔ : A powder-based system
What are the pros/cons to a powder-based system work?
- ANSWER ✔ : - Can make higher quality parts
- Can print metal
- More complex
- Requires additional clean-up and post-processing
What are the cost benefits of FDM printers? - ANSWER
✔ : - Typically the lowest cost machines in initial purchase
and materials
- Hardware isn't as expensive
- Spools of plastic strands used by FDM printers are
widely available and created at a low cost
T/F: Additive manufacturing uses much less material than
many other traditional "subtractive" manufacturing
processes. - ANSWER ✔ : True
Which of the following is typically the cheapest type of 3D
printer to purchase?
,a. Powder-based
b. FDM
c. SLA
d. None of these are correct. - ANSWER ✔ : b. FDM
T/F: SLA printing uses a plastic strand that's pushed
through a heated nozzle in a specific pattern, producing
one layer at a time. - ANSWER ✔ : False
Which of the following is typically the most expensive type
of 3D printer to purchase?
a. Powder-based
b. FDM
c. SLA
d. None of these are correct - ANSWER ✔ : a. Powder-
based
T/F: 3D printing technology is expanding and is now able
to print metal parts. - ANSWER ✔ : True
What does "FDM" stand for? - ANSWER ✔ : Fused
Deposition Modeling
How does FDM work? - ANSWER ✔ : FDM takes a long
strand of plastic and pushes is through a heated nozzle in
a pattern in the shape of the part.
Which part of a FDM printer moves along two axes in a
single plane? - ANSWER ✔ : The nozzle
, How many layers does an FDM printer go at a time? -
ANSWER ✔ : One
How does an FDM printer move on to printing the next
layer of a part? - ANSWER ✔ : The build plate that the
part's printed on moves downward so the next layer can
be printed on top.
How does the build plate move in FDM? - ANSWER ✔ :
The build plate moves vertically in a third axis of motion.
What does SLA stand for? - ANSWER ✔ :
Stereolithography
How does SLA work? - ANSWER ✔ : A laser is
projected into a pool of liquid resin and hardens the resin
at a specific spots which forms the shape of the part layer
by layer.
How is the laser controlled in SLA? - ANSWER ✔ : The
laser is controlled by mirrors that move underneath the
pool of resin.
How dies the build plate move in SLA? - ANSWER ✔ :
The build plate moves upward and downward in a single
axis.
What are FDM and SLA most common for? - ANSWER
✔ : Smaller benchtop models
