The technology is defined indirect on powder-bed because the piece “grows” inside a full volume of material, selectively activating only the areas that have to be consolidated, through the deposition of water. The printing process is relatively “simple” (we invite you to watch this video to understand how the printer works) and for this reason with the BAM team we worked on details – technical specifications, parameters, variables – that make the difference.
We started with the improvement of the whole printing process, developing the system of loading and depositing the powders and the methods of selective deposition of the liquid that activates the binder and consolidates the powder bed.
Then we moved to the study of the raw materials, that often coming from the recovery of other processes waste to fulfill our need and attention to environmental sustainability. The study of materials characteristics and properties allows us to define the best formulations according to the types and quantities of aggregates and binders used.
Finally, we have come full circle. We tested and optimized operating parameters such as the print speed or the quantity of liquid deposited, depending on the synergies between materials and process, each with its particular conditions and characteristics, and the application needs of each time different.
Over time, during reciprocal secondments, we also produced and printed new objects, to evaluate and confirm potential and applicability of technology and materials in different sectors. From the artistic and cultural heritage (for example Ebe, in the image below) to the civil and environmental components (such as sewage or road part), from the aesthetic design (Schwarz P surface, see the video) to the functional one (load speakers). Having also lighter and recreational moments: because this, as well as what was said at the beginning, keeps the commitment to work fertile and stimulated.
