Question

sls: materials. use the information below to answer the question. when deciding what materials are suitable for selective laser sintering, you want a material that has good thermal resistance. types of materials. nylon is a polyamide (thermoplastic), which can be re - melted. these properties make nylon a good choice of material for the sls process. pa - 12 nylon has good strength, cost - effectiveness, and chemical resistance. it has a matte, tough surface. alumide has a dull gray metallic appearance and good temperature resistance. pa - gf is a glass - filled nylon that has a good strength to weight ratio, and good wear resistance. characteristics of pa - 12. pa - 12 has good dimensional stability, which makes it good for a range of applications. mechanically, it has good impact resistance and good moisture resistance. it also has good chemical resistance along with good heat resistance. the mechanical properties of pa - 12 can be further enhanced with the addition of carbon, glass, or aluminum to increase the tensile strength. the mechanical properties of pa - 12 nylon can be enhanced with the addition of what? iron, copper, or silver; carbon, glass, or aluminum; clay, wax, or adhesives; resin, acetone, or plastic

Explanation:

The text mentions that the mechanical properties of PA - 12 nylon can be enhanced with the addition of carbon, glass, or aluminum to increase the tensile strength.

Answer:

carbon, glass, or aluminum
