Computer-Aided Design
Based on your reading and lectures, why is there interest in increasing the use of AM
techniques in medical implant fabrication? Select all that apply.
A) AM allows the printing of custom shapes tailored to the implant location in the body.
B) The cost of AM is higher, leading to a larger profit for the medical community.
C) AM offers the ability to rapidly produce high complexity parts in an on-demand basis,
often within the hospital itself.
D) The high-volume production nature of AM enables it to produce a single complex
shape applicable to all patients. - Answers - A) AM allows the printing of custom shapes
tailored to the implant location in the body.
C) AM offers the ability to rapidly produce high complexity parts in an on-demand basis,
often within the hospital itself.
T/F: Luckily, all materials can be printed using AM techniques and do not represent a
challenge in the broader application of these technologies. - Answers - False
Choose all statements that differentiate rapid prototyping (RP) from additive
manufacturing (AM) according to your reading and lectures.
A) RP incorporates the use of a broad range of materials, including metals.
, B) In AM, multiple printing technologies have been developed to allow the direct
production of parts that can be used in various applications.
C) RP involved the early use of layered deposition approaches to provide a rapid
method for the evaluation of part design.
D) AM is limited to the use of polymer systems. - Answers - B) In AM, multiple printing
technologies have been developed to allow the direct production of parts that can be
used in various applications.
C) RP involved the early use of layered deposition approaches to provide a rapid
method for the evaluation of part design.
Which statement can be used to describe the potential advantages of AM over
conventional manufacturing (CM)? Choose only one option.
A) AM techniques avoid the design bottleneck and long lead times that typically slowed
the development of new products in CM.
B) AM has a relatively fixed "tooling cost" as new designs do not require the
development of dedicated molding or forming requirements for a new part.
C) Products made using AM have the advantage of significant manufacturing cost
savings as the number of parts made increases.
D) AM offers the ability to more readily allow for part customization.
E) All of the above.
F) Statements a), b), and d) only. - Answers - F) Statements a), b), and d) only:

Define the acronym "EBM" in the context of Additive Manufacturing. - Answers -
Electron Beam Melting
The following describe some important aspects of Inkjet Printing:
A) Involves feedstock composed of an ink or paste
B) Uses a laser to heat the feedstock to allow it to melt in place
