| dc.description.abstract | Additive manufacturing (AM) is especially suited for unique objects or low production batches since it does not require expensive tooling. The AM market has undergone enormous growth, even though there is still a significant limitation in this technology type when producing large parts. Powder bed technology, particularly binder jetting, allows the production of several types of materials. The print size is directly related to the machine’s build volume size when using powder bed technology. Moreover, materials used in powder bed processes are usually high-cost materials, making large prints not affordable. Instead of working with high-cost types of powder, it is possible to replace them with low cost, biodegradable materials, like wood, or waste materials like ground tire (GTW). Using materials such as this allows low-cost production parts while contributing to the incorporation of residues that otherwise would have to be discarded, with a low environmental impact. This work studies the usage of waste materials in small grains and calibrated dust with different sizes as a matrix in a binder jetting machine with a build volume of 1m3. Wood dust and GTW are being studied and additives can be added to the bulk material to affect the powder deposit ability, printing behavior, final part properties and post-processing behavior. It was possible to produce test specimens, but the machine had to be refilled each layer manually. The rest of the printing process was made automatically, producing specimens that were tested successfully. | pt_PT |
