$($a$)$ Explain the differences between feature size and resolution in the vector$-$scan Vat Photopolymerization process.

$($b$)$ Can the layer thickness be changed in vector$-$scan VPP$?$ If yes, how?

$($c$)$ Why is there a post$-$curing process in the stereolithography AM$?$ Explain what happens if the postcuring process is not done properly.

$($a$)$ Categorize AM feedstock in terms of the physical shape$/$material state.

$($b$)$ Give a material example and an AM process for each category.

$($a$)$ Explain the differences between different types of polymers in terms of the molecular bonding mechanisms.

$($b$)$ Name an AM process that can be used to fabricate parts from each polymer type.

What are the main differences between chemically induced sintering and liquid$-$phase sintering$?$ Explain with an example for each process.

$($a$)$ A porous bone replacement structure is to be made from stainless steel $316$L$.$ Which of the following AM processes would you use for this purpose: PBF or DED? Justify your answer.

$($b$)$ If the melting temperature of the alloy feedstock is $1410C,$ what will be the proper temperature range for solid$-$state sintering of the part? Show your calculations and explain your response if needed
