Question

sls: comparison with injection molding
use the information below to answer the question
injection molding is a process whereby nylon beads are melted and injected into a
mold. this process is used to make large production runs of an item when a thousand
or more are needed. creating the mold takes time and money. if a few hundred items
are needed, sls might be an option, depending on the strength and nature of the
item. sls wont have the same mechanical properties as injection molding, however.
sls advantages

• sls is faster than injection molding
• the start - up cost is less than injection molding.
• it can do more complex geometry than a traditional injection mold process,
• having a natural fillet or radius is stress - relieving for the print.
• a prototype can be created before going to injection molding.

if a few hundred items are needed, what process can be an
option depending on the strength and nature of the item?

Explanation:

The text states that when a few hundred items are needed, SLS might be an option depending on the strength and nature of the item, as injection molding is for larger production runs (thousand or more) and SLS has advantages like lower start - up cost and faster speed for smaller runs (a few hundred) in such cases.

Answer:

SLS (the option with text "SLS")
