Material

Aluminum (AlSi₁₀Mg)

The strength, thermal properties, low weight, and flexible post-processing of this aluminum alloy, AlSi₁₀Mg, make it a favorite for prototyping and manufacturing — especially in industries like automotive, aerospace, and automation. With this alloy, users can create larger models than with any other metal 3D printing material.

Actual values may vary with build conditions.

Strong tensions due to part geometry may distort parts, potentially leading to greater deviation in values. Values for surface roughness depend on the orientation of the surface; downward-facing surfaces and surfaces with support will be rougher.

These values show the material characteristics without additional stress relief heat treatment. Extra heat treatment steps for even higher mechanical properties may be possible, e.g. for serial produced parts.
