EOS Metal

3D Printer
For high quality parts

Reliable manufacturing machines
The EOS standard in metal 3D printing

DMLS® metal-based additive manufacturing technology has been the technology of choice for EOS metal additive manufacturing machines for almost three decades, and is now the standard in metal 3D printing. Metal parts produced with DMLS technology achieve consistent quality with properties similar to those produced by conventional casting or forging processes.EOS offers industrial 3D printing systems that can be flexibly integrated into existing production environments with a range of different build space sizes, laser powers and scalability. Our metal 3D printers are based on the DMLS process.Additive manufacturing systems in proven DMLS quality – perfectly tailored to your individual manufacturing requirements.We offer compact 3D printing systems for manufacturing delicate metal components, powerful mid-size solutions with a broad material portfolio and ultra-fast four-laser systems for the production of high-quality serial parts.

Smart Fusion

Advanced process control

The new EOS process control solution includes the first real-time intelligent heat management of its kind that reduces or eliminates support structures and operates 2 to 5 times faster than other technologies.

Freedom of design

Shorter time to market

Reduced cost per part

Smart Fusion’s real-time capability automatically adjusts laser power to address potential manufacturing issues quickly and efficiently. The technology measures the laser energy absorbed by the powder bed and adjusts it using advanced algorithms. As a positive side effect, support structures can be avoided or even eliminated. This not only saves time, but also reduces your cost per part (CPP) through reduced post-processing and reduced material usage.    This novel software solution enables, more applications, a positive business case for metal AM applications, especially for companies with highly technical applications such as energy, space technology, mobility and aerospace.In essence, Smart Fusion combines with existing EOS monitoring solutions and employs advanced algorithms to monitor the build layer by layer, providing more homogeneous and consistent parts.From a data flow perspective, EOSPRINT prepares the data, which is sent to the 3D printer, Smart Fusion works with its optical tomography (OT) camera through which the generated images adjust the laser. 

Realities and advantages of unsupported 3D printing on metal

EOS metal materials for 3D printing

In additive manufacturing (AM), support-free construction refers to the development of ways to produce 3D printed parts that are completely independent of any support structure. Supports are commonly used in the build process to reinforce and maintain the structure of the part being created. This is necessary for a number of reasons, depending on the size and shape of the part being built.

The supports are strategically placed to prevent deformation due to thermal stresses, to promote heat transfer out of the molten material and to protect the part being formed from the coating machine’s blade, which can alter the shape of the part if impacts occur. They can also provide additional rigidity to the part during the manufacturing process, for example, by fixing it to the manufacturing plate to keep it stable.

To create layers of additive material in the right shape, some of the powder is used to create supports that hold the elements protruding from the part being printed. The idea of unsupported printing would eliminate these supports and allow a fully self-contained, ready-to-use part to be built as soon as printing is complete.

Copper 3D Printing

Copper 3D printing is one of the newest areas of additive manufacturing, and one of the fastest growing. Until a few years ago, it was problematic or impossible to print three-dimensional objects with copper because the metal’s reflectivity and high thermal conductivity made it difficult to use conventional 3D printers.

As a pioneer in the field of copper 3D printing, EOS has mastered these challenges, so that today advanced applications can be printed with copper, from rocket propulsion systems to copper coils. The material properties of copper make it ideal for any application that requires good conductivity, both thermally and electronically.

In the past, copper parts had to be forged, cast or machined.3D printing with copper now makes it possible to produce much more complex geometries that, for example, increase the efficiency of electric motors or enable new types of heat sinks in power electronics.
