SLA (3D Printing) – an additive process that builds parts in a pool of UV-curable photopolymer resin using a computer-controlled laser. The laser is used to trace out and cure a cross-section of the part design on the surface of the liquid resin. The solidified layer is then lowered just below the surface of the liquid resin and the process is repeated. Each newly cured layer adheres to the layer below it.
Pros – Cost is quite competitive and the technology is widely used. Complex geometries and great surface finishes, when compared to other 3D printing options. Good option when you need a master part made.
Cons – Parts are not very strong so not suitable for function testing and can become even more brittle over time if parts are subjected to sunlight.
SLS (3D Printing) – Powdered material is fused together by lasers to make a solid part and then the process is repeated layer by layer to produce a finished part. SLS parts can be more durable than SLA parts but the surface finish will feel rougher with a distinct grain. SLS parts can be pretty strong but they are considerably weaker than parts made through subtractive CNC machining or injection molding. There are a number plastics you can choose from but Nylon based materials are the most common materials used.
Pros – Complex geometries are possible, good for form and fit testing. Parts tend to be more durable.
Cons – Typically, not great for rough functional testing if strength of part is required for function. Parts have a rougher feel and may need post production if perfect finishes are desired.
