Surface Optimization of Components Obtained by Fused Deposition Modeling for Air-Plasma-Sprayed Ceramic Coatings

Additive manufacturing is an emerging disruptive 3D printing technology that stimulating innovations in design and engineering, materials, thanks to the prospects of reducing cost waste increasing efficiency; doing so, it presents potential have marked industrial, economic, societal impacts. Thermoplastic polymers show some ideal characteristics for most common additive methods, this aids improvement accuracy reliability makes inroads customized high-design-flexibility polymer parts. Despite this, material family strongly sensitive temperature, one viable ways limiting weak point surface coating with thermal barriers. The focus work was optimization process producing thermoplastic components improve adhesion a barrier on their surface. In detail, flat plate specimens ULTEM 1010 were obtained by fused deposition modeling technique varying two significant parameters, enhanced visible rasters raster air gap; then, surfaces covered thin ceramic plasma spray system. A micro-geometric analysis conducted using confocal microscope thickness measurements highlighted global larger roughness value, presence more peaks large area, complexity texture can be considered as supporting factors improving mechanical gripping allowing uniform powders substrate.
