Pros and Cons of
Aluminum CNC Machining
Aluminum CNC Machining
With a density of about 2.7 g/cm³, aluminum is ideal for weight-sensitive applications.
Easy to cut, drill, and shape, enabling complex and precise designs.
Naturally resists corrosion, making parts durable and long-lasting.
Pros of Aluminum CNC Machining
Pure aluminum is soft, so alloys are often preferred for CNC machining.
Aluminum costs more due to the extraction & processing required from bauxite ore.
Its soft surface can scratch and dent easily, especially with glossy finishes.

What’s SLS 3D Printing?SLS (Selective Laser Sintering) is an industrial powder-bed fusion additive manufacturing technology. It sinters micron-scale thermoplastic powders layer by layer. Because the surrounding unsintered powder supports the part during printing, SLS enables complex organic geometries, interlocking assemblies, and high-strength end-use production parts with isotropic mechanical performance.
