3D printing with aluminium is done through Selective Laser Melting (SLM). This technology melts 30-micron layers of aluminium into powder thanks to a 400 W laser. The difficulty in welding aluminium means that it is essential to have good knowledge about this printing technique and the material itself to guarantee the best quality and repeatability of the entire production process.
To create quality prints with aluminium, it is essential to have good know-how of SLM technology and of the material. Factors such as layer thickness, the number and geometrics of the manufacture supports, and the printer parameterisation all play a key role.
The high mechanical properties per mass unit, combined with topologically optimised designs mean that this material can be used for extremely light designs. Reduced tooling costs of short-runs in aluminium casting or injection processes. High corrosion resistance, which can be increased when anodized.
– Send us your 3D file ready to print.
– If you do not have the file, send us the item and we will create the CAD file.
– If you need a design from zero, our designers will gladly prepare a quote for you.
– We will create the process file adapted to the technology and materials that will be used to produce your item.
– We prepare and condition the printer to guarantee optimum quality.
This step is key when meeting your requirements, and it is one that we are highly specialised in. The removal of the printing support structures, heat treatments, and surface finishes (blasting, polishing, tooling) are some of the most common post processes.
One of the most common uses of aluminium printed parts is the manufacturing of short-runs or prototypes to streamline the development of parts which will subsequently be manufactured in high volumes (melting, injection). Other uses are related to lighter structures or heat transfer, such as in the case of personalised heat exchangers.
The Renishaw AM400 includes the latest developments of the AM250 platform such as the improved optical control software, the reviewed gas flow system, and window protection. The laser also has a power of 400 W, meaning it has a beam diameter of 70 µm.
The construction volume is 250x250x300 mm.
The versatility of its design and the possibility to generate new processing parameters means that this equipment can work with a range of materials.
We design conformal cooling channels for plastic and aluminium injection inserts. With our inserts the cycle time is improved in addition to the quality of the injected item.
