Required constraints and criteria for the AM application selection

Property	Description	Scenario 1	Scenario 2	Scenario 3
Melting point	It must be lower than 1,400°F as required by the foundry company. The low melting point assists the flow of the melting pattern material	Constraint and Criterion	Criterion	Criterion
Young’s Modulus	This reflects the pattern’s stiffness. A high Young’s modulus can improve the precision of the molds made by the patterns	Criterion	Constraint	Criterion
Surface finish	The better surface finish of the patterns leads to a smoother surface of the cast parts	Criterion	Criterion	Criterion
Printing speed	This affects the production time of the final parts	Constraint	Criterion	Constraint and Criterion
Dimensional accuracy	This relates to the utilization of some machining processes that can improve dimensional accuracy	Criterion	Criterion	Criterion
Autoignition temperature	A low autoignition temperature facilitates the removal of the patterns in the investment casting process	Criterion	Criterion	Constraint
Cost	This refers to the cost of pattern production	Criterion	Criterion	Criterion
