As a nickel-based heat resistant alloy, Inconel 718 is high in strength and corrosion resistance, and can be used at temperatures between -252°C and 704°C. The material’s high-temperature strength is derived from its ability to create a thick, stable passivating oxide layer at elevated temperatures, protecting it from further attack.
Inconel, which has good tensile, fatigue, creep and rupture strength, is suitable for parts used in jet engines, rocket engines, gas turbines, power systems, and related equipment exposed to extreme environments.
In terms of its geometric limits, Protolabs offers the following: a minimum wall thickness and feature size of 1 mm; minimum embossed details measuring 0.5 mm high and wide (0.8 mm for text and images); minimum engraved details of 0.5 mm deep and 0.6 mm wide (1 mm wide for text and images); and a maximum part size of 245 by 245 by 300 mm.
Maraging Steel 1.2709 is a pre-alloyed, high-strength steel in fine powder form. The material has good mechanical properties and is easily heat-treatable using a thermal age-hardening process. Maraging Steel 1.2709, which offers high strength, high hardness and high temperature resistance, can be used for tooling applications and parts found in aerospace and motorsport applications
In terms of geometric limits, the following applies: a minimum wall thickness and feature size of 1 mm; minimum embossed details measuring 0.5 mm high and wide (0.8 mm for text and images); and minimum engraved details of 0.5 mm deep and 0.6 mm wide (1 mm wide for text and images).
The latest materials add to Protolabs’ existing metals for its DMLS service, which include aluminium, 316 stainless steel and titanium.
