Seminar given by Carlos Doñate-Buendía, from University Jaume I
Additive manufacturing techniques offer the material design versatility required to produce custom parts suitable for aeronautic, consumables or medical applications. However, the library of polymer materials processable and their properties are limited, reducing the possibility of manufacturing parts with custom functionalities. To address this limitation, nanoparticle addition to base materials employed for LPBF has been proved to widen the processable materials and provide additional functionalities. With this aim, a general route to nanoadditivate polymer powders with homogeneously dispersed nanoparticles will be described. Without the addition of chemical precursors, spherical nanoparticles are generated by pulsed laser ablation (PLAL) or pulsed laser fragmentation (PLFL) in liquids. Nanoparticle adsorption on the polymer powder is conducted directly in the obtained colloidal dispersions after PLAL/PLFL, followed by drying, powder analysis and LPBF processing. The process success and versatility in terms of nano-additives and base polymers employed is demonstrated for different nanoparticles (gold, silver, carbon, iron oxide…) and polymers (TPU and PA12). Showing the possibility to widen the selection of processable materials and provide them with additional optical, bactericidal or magnetic functionalities to materials such as polyamide 12 (PA12).
