Intuitive plug-and-play solution for large format metal 3D printing

Meltio’s Robot Cell is a turnkey solution, which contains the Meltio Engine integrated on an industrial robot. The system is a cost effective, plug and play solution, for printing highly accurate and fully dense metal parts. Offering a great deal of advantages over traditional methods, the system allows the customer to print at large scale by utilizing the large working envelope of the 6 axis robot. This large format metal 3D printer also gives you the ability to perform non planer extrusion, by synchronising the robot and rotational positioner you are able to print non planar and complex geometries.

Perhaps the biggest advantage of the Meltio Robot integration is the potential to print near-net parts – meaning 3D printed parts are very close to the final desired shape and dimension. By reducing the amount of material that needs to be removed or processed, near net shape manufacturing can significantly reduce the time and cost associated with 3D printing as a consequence of the reduction in the wastage of raw material and energy.

The Meltio Engine uses standard metal wire and produces clean and consistent layers. It is capable of printing stainless steels, carbon steels, titanium alloys, nickel alloys, copper and aluminium. Using a directed energy deposition method, a laser is used to melt and fuse the material as its deposited layer by layer. By integrating the Meltio Engine on a robot, the high payload ensures that the system follows the additive toolpath precisely. 

As the integrator, CNC Robotics focuses on the installation, training and safety of the system. We train users on how to use the system as well as completing a site acceptance test (SAT) enabling you to focus on developing 3D printing applications and manufacturing parts in short time.

High resolution near net shapes

This advanced technology is capable of achieving remarkably high resolutions, particularly for intricate and small features. By employing a layer-by-layer approach to selectively add material, it effectively minimizes material waste, distinguishing itself from conventional manufacturing methods.

Laser Cladding

This process involves depositing a thin layer of material onto a substrate using a focused laser beam, offering precise control over the coating thickness. The technique is employed to impart characteristics such as wear resistance, corrosion resistance, and improved thermal conductivity to critical parts. By selectively adding material where it is needed, laser cladding ensures targeted reinforcement, extending the service life of components and reducing the need for full replacements.

Large and complex parts

Meltio allows for the creation of large and intricate structures with high precision. This capability is invaluable in industries like aerospace, where large aircraft components, such as wing sections or engine parts, require both structural integrity and intricate designs. The layer-by-layer additive approach enables the production of these parts with reduced material waste and increased design freedom. Moreover, Meltio’s ability to work with a variety of metal alloys adds to its suitability for crafting large and complex parts tailored to specific industrial needs.

Repairs & Feature addition

Addressing issues such as corrosion, wear, or cracks, this method facilitates the incorporation of new features onto existing components, enabling upgrades or modifications without the necessity of re-manufacturing the entire part. Add layers of material to existing stock to produce a highly dense metal part, require minimal post processing and material removal.
