Chapter 29 Rapid Prototyping
29.1) Describe a situation in which you might want to build a foam core prototype rather than build a solid
model to test out a concept.
29.2) Describe a situation in which it might make more sense to make the first prototype as a solid model rather
than a physical model.
29.3) True or False: because of its sheet nature, foamcore is only suitable for creating planar shapes.
False: it is possible to make 3-D curved shapes using foam core.
29.4) What is the purpose of using “tab and slot” construction?
29.5) What are the advantages of SLS over SLA prototyping? What are the drawbacks?
29.6) Contrast hard tooling with soft tooling. List advantages and disadvantages for each.
Hard tooling is made with hard materials, typically metals, while soft tooling is made with softer materials:
29.7) True or False: Cast parts made from soft tooling are limited to low durometer (soft) materials.
29.8) List at least three distinct functions that a schematic diagram serves in the design/build process.
Documenting the design
29.9) In the context of electronic design, what is SPICE?
29.10) What are some drawbacks to circuit prototypes made using solderless breadboards.
29.11) What is the major advantage of a wire wrapped prototype over a solderless breadboard prototype?
