ABS — Material Description

ABS (acrylonitrile butadiene styrene) is a strong, durable, and chemically resistant thermoplastic widely used for functional prototypes and engineering parts. It offers better mechanical performance than PLA, making it suitable for applications requiring toughness, impact resistance, and heat stability. ABS models have a slightly rougher surface due to the FDM printing process, but vapour smoothing can significantly improve appearance.

Aluminium (AlSi10Mg) — Material Description

Aluminium alloy AlSi10Mg is a strong, lightweight metal with excellent thermal properties, ideal for high-performance functional parts. It is manufactured using SLM/DMLS metal 3D printing, where aluminium powder is selectively melted by a laser to form dense, high-strength components comparable to machined parts.

Unlike polished or milled aluminium, 3D-printed aluminium has a matte grey finish with a slightly rougher texture. The alloy contains silicon, giving the surface a subtle, fine sparkle.
