SLS & SLA， how to choose?
When you're doing prototyping, do you also find yourself torn between SLA and SLS 3D printing? Actually, it's not that hard a choice.
If you care most about high precision, a smooth surface finish, and visual appearance, then SLA is the better choice – for example, automotive prototypes, medical models, and display pieces.
If you prioritize structural strength and wear resistance, then SLS nylon is the way to go – functional parts, structural components, such as gears, and etc.
