Advantages of
3D Printing

Multiple Choice

3D printing is very useful for prototyping. Which of the following is an example of prototyping?

• Amy uses a 3D printer to print out a key chain as a gift for her friend's birthday. 

• John uses a 3D printer to print a golf ball for use at the upcoming tournament.

• Will uses a 3D printer to print a model of a new smart phone holder he designed. He is taking it to a trade show hoping a manufacturer will pay him to use his design. 

• Danielle uses a mold to make 100 plastic sock-holders, which she will be selling at her garage sale on Saturday.

Multiple Choice

Complete the sentence. Subtractive processes involve...

• Adding layers and layers of a material to create a product.

• Removing sections from a piece of raw material to create a final product.

• Gluing or soldering two pieces of material together.

• Melting two different types of metals and mixing them together.

Multiple Choice

How does 3D printing benefit the prototyping process?

• 
  

• Slows down the prototyping phase

• Limits design modifications

• Allows rapid iteration

• equires extensive tooling

Multiple Choice

Compared to traditional manufacturing methods, what is a notable advantage of 3D printing in terms of material usage?

• Higher material waste

• Lower material precision

• Reduced material waste

• Increased material cost

Multiple Choice

How does 3D printing contribute to time and cost savings in the production process?

• Slower production speed

• High tooling costs

• Increased material waste

• Rapid production without tooling

Multiple Choice

What is the fundamental principle behind additive processing, such as 3D printing?

• Adding material layer by layer

• Removing material layer by layer

• Shaping material through compression

• Utilizing molds for mass production

Multiple Choice

In which industry is additive processing commonly used for producing intricate prototypes and end-use products?

• Agriculture

• Woodworking

• Textile Manufacturing

• Automotive

liquid, photosensitive resin is poured into a
vat (or tank), and UV light interacts with the
resin to polymerize (i.e., cure, solidify) it

material starts as a spool of plastic filament
or metal wire
print head extrudes the melted material
layer by layer

Fused Deposition Modeling
(FDM)

uses high-powered lasers to sinter, or bind,
finely powdered material together into a
solid structure

Selective Laser Sintering

3D Printing
Methods

​Stereolithography

Multiple Choice

In 3D printing, a higher mesh resolution is generally associated with:

• 
  

• Faster printing speed

• Smoother surface finishes

• Increased layer adhesion

• Reduced material flexibility

Multiple Choice

How does increasing mesh resolution impact the size of a 3D model file?

• File size decreases

• File size remains constant

• File size has no correlation with mesh resolution

• File size increases
