Titanium

Titanium was first discovered in England in 1791. Approximately 150 years later and through the introduction of the Kroll-Process, titanium became a com-mercial product. Titanium (Ti) with the ordinal number 22 in the periodic system of elements is defined as a transi-tion metal. It is one of the most common elements on the earth`s surface and is lis-ted as the 10th most common element.

The material is particularly resistant to cor-rosion and with high mechanical proper-ties compared to the low specific weight. Pure titanium has a density of 4.54 g/cm3 with a melting point of 1677 centigrade.

Material StructureComponents produced by SLM® in titanium show a homogenous, dense structure. If required, the structure can be heat treated to achieve the required shape.

Tool Steel and Stainless Steel

Going back two thousand years people were searching for cutting materials which were not only hard but also tough. Along with mass industrialisation at the beginning of the nine-teenth century the development of steel and its alloys materialised into what we now know as tool steel and stainless steel.

These materials reach a high skin hardness when heat treated, with a low carbon content of only 0,5 - 1,5 %.

Alloy constituents, when added can adjust the properties to an exact specification. Even corrosion resistant steels can be produced in the same way. These so called stainless steels are known for their low nitrogen and phos-phor content of less than 0.025% and today these materials are widely used in the mould making industry. Through the SLM® Techno-logy the processing and extended application of these steel materials has been developed even further.

Material StructureComponents produced by SLM® in steel show a homogenous, dense structure.

Due to the particularity of the SLM® building process, levels of hardness can be achieved which cannot be equalled by conventio-nal heat treatment methods. Through post treatment, components can be brought to the condition required.

Aluminium

Aluminium (Al, ordinal number 13 in the periodic system of elements) belongs to the light metals group and cannot be found naturally in solid form. Aluminium is obtai-ned from bauxite. Bauxite is the third most common element on the earth´s surface.

Aluminium has a density of 2.7 g/cm3 and has a melting point of 660 centigrade. It can be processed relatively easily by cas-ting, machining and pressing. Due to its low strength it is used to produce alloys from silicon, magnesium, copper, manganese and zinc. Aluminium oxide (Al2O3) can also be found extensively as a ceramic.

Material StructureComponents produced by SLM® in Aluminium show a homogenous, void free structure.

Due to the particularity of the SLM® building process a typical hardness can be achieved. Through post treatment the components can be brought to the required condition.

Cobalt-Chrome

Cobalt-Chrome alloys are standard alloys in the medical and dental fields.

Due to the high hardness, Cobalt-Chrome alloys are used to produce dental pros-theses. This is also influenced by the bio-compatibility of the alloy. Being a tough material, Cobalt-Chrome alloy is usually cast and not machined.

Other uses for Cobalt-Chrome are prosthesis and knee or and hip joint implants.

Material StructureComponents produced by SLM® in cobalt-chrome alloys show homogenous and pore free structures.

Since CoCr is difficult to machine, the SLM® process offers a quick and low cost method of producing components in these materials.

Nickel-base alloys

Developed in the early 1960‘s, IN718 is still considered the material of choice for the majority of aircraft engine components with service temperatures below 1200°F (650°C). Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing also significant amounts of iron, niobium, and molybdenum along with lesser amounts of aluminum and titanium. It combines corro-sion resistance and high strength with out-standing weldability including resistance to postweld cracking. The alloy has excellent creep-rupture strength at temperatures to 1300°F (700°C).
