Metal Variety:from dental prostheses to turbine blades

Customers from highly varied sectors utilise our machines to produce complex build parts for a large number of applications – from dental prostheses through to turbine blades. All of these products have one thing in common: they must meet the highest standards in terms of stability, surface structure or biocompatibility. And the number of utilisation scenarios is on the rise: almost all geometric forms are possible.

3D printing versus conventional manufacturingIn scenarios involving the production of smaller series of complex build parts, additive manufacturing is often

faster build time reduced by up to 90 percent

more efficient weight reduction of up to 60 percent, reduction in number of components of up to 95 percent

more cost-effective reduction of build part costs of up to 70 percent

more flexible „complexity comes for free“

in higher quality superior materials properties such as density, stability, temperature and corrosion resistance, surface structure and biocompatibility

AerospaceThis air duct made of titanium is produced in high precision without major rework.

General

With a density of 2.7 g/cm³, aluminium is classified as a light metal. It is highly suited to processing and is used, for example, in thin-walled components with complex geometries. Aluminium also displays good electrical conductivity. Due to its low strength, it is used above all in alloys; currently the most common alloy is AlSi10Mg. Typical alloying additions are silicon, magnesium, copper or manganese. In alloyed forms, aluminium is used to produce components with high strength and high dynamic loadability. The components are optimal for use in areas such as aerospace engineering and the automotive industry.

General

Cobalt-chrome alloys are distinguished by their especially high hardness as well as high ductility. Additionally they are corrosion resistant. Due to their high bio-compatibility, cobalt-chrome alloys are among the standard alloys used in medical and dental technologies. They are used to produce dental as well as knee and hip prostheses.

Their resistance to heat makes them well-suited for use in high-temperature areas, such as in jet engines. Since cobalt-chrome components are very hard, there are limitations when it comes to exposing them to cutting processes. The SLM-process provides a low-effective option to quickly produce cobalt-chrome components.

Ni-Alloys

General

Materials like IN or HX are examples of highly heat-resistant and corrosion resistant nickel-based alloys. In most cases, these alloys contain chrome, iron, niobium and molybdenum and other alloy components and they are often known as superalloys. Nickel-based alloys withstand higher temperatures than steels and they are also highly weldable. Their resistance to temperature is achieved through a mixture of dispersion hardening, precipitation hardening and solid solution strengthening.

Nickel-based alloys exhibit good mechanical characteristic values such as high tensile strength and good endurance strength. IN can be used at temperatures of up to 700 °C. HX can even be used at temperatures of up to 1200 °C. This makes these alloys ideally suited for aerospace technologies and for turbine production.

Another area where nickel-based alloys are used is toolmaking. These alloys are also suitable for sustained heat treatment and mechanical post treatment.

General

Thanks to their high strength and relatively low density, as well as excellent corrosion resistance, titanium components are found across a broad spectrum of applications. Titanium and its alloys have already been successfully put to use, for example, in the automotive industry and in aerospace engineering, since around 1950.

Pure titanium is used primarily in chemical industries, process engineering or in medical technologies, wherever good corrosion resistance is especially required. An added advantage here is titanium’s low thermal expansion. Its bio-compatibility also makes titanium suitable for use in medical technologies. Therefore, dental implants or prosthetic hips, for example, can be made from titanium.

The alloy Ti6Al4V is by far the most common titanium alloy worldwide. The main reason for this is its well-balanced mechanical properties and the many years of industrial experience with this material.

Ti-Alloys

General

Components made from tool or stainless steels are known for great hardness with a high ductility. Through selective application of alloying components, the material properties can be precisely adjusted. This means that even corrosion-resistant steel alloys like 1.4404 (316L) can be treated using the SLM-process. Applications for corrosion-resistant alloys are found in medical technologies, the automotive industry as well as in aerospace engineering. Tool steel is used above all to produce tools and moulds, and its layered structure enables components to be fitted with integrated cooling canals.

The good mechanical characteristic values of tool and stainless steel make it suitable for use in places that are exposed to heavy strain, because its high resistance to wear and tear or surface hardening keep abrasion to a minimum. Steel can also be used at high operating temperatures which reduces the amount of wear and tear on the tools.

SLM 280 2.0

the top seller:

The Selective Laser Melting Machine SLM 280 2.0 provides a 280 x 280 x 365 mm³ build envelope and a patented multibeam technology. The SLM 280 2.0 is equipped with one or two fiber lasers with 3D scanning optics. The machine is available in several configurations providing single optics (1x 400W or 1x 700W), twin optics (2x 400W or 2x 700W) and dual optics (1x 700W and 1x 1000W). Depending on how the build parts are arranged, a 80% higher build rate can be achieved.

This model comprised almost 70% of our new order intake in 2014. The SLM 280 is equipped with high-performance multi-laser technology, and manufactures 68% faster than the SLM 125. The SLM 280 is especially suitable for the industrial series manufacturing of medium-sized build parts.

SLM 500the flagship:

The Selective Laser Melting Machine SLM 500 provides a build envelope of 500 x 280 x 365 mm³ and the patented multi-beam technology. In the high-performance SLM 500 machine, four quad fiber lasers (4x 400W or 4x 700W) are in action simultaneously, increasing the build-up rate by up to 90% compared with the twin configuration (2x 400W or 2x 700W).

The SLM 500 has ranked as the premium product in our product range since its market launch of the end of 2013. The unit can be equipped with up to four lasers, thereby boosting the build rate by more than 250% compared with the singlelaser machine. The SLM 500 is thereby the most productive laser melting machine on the market currently. It accounted for 18% of our new order intake in 2014.

SLM 125 the compact model:

The Selective Laser Melting Machine SLM 125 offers a build envelope of 125 x 125 x 125 mm³. The flexibly applicable machine with high productivity has been designed for quick results in the research and development sector, as well as for the production of smaller build parts. In addition, the SLM 125 provides a build volume reduction of 50 x 50 x 50 mm³ thus decreasing the amount of powder by 80%.

SLM Solutions‘ most compact machine is equipped with single-laser technology, and is particularly suitable for the production of small workpieces, as in medical applications and technology, or in research and development.
