Moisés Batista, Ana Pilar Valerga, Jorge Salguero, Severo Raul Fernandez-Vidal, Franck Girot 2 State of the art of the fused deposition modeling using PLA: improving the performance Abstract: One of the main processes within the additive manufacturing is fused depo- sition modeling, due to its versatility, its high capacities, and its low cost. However, this process has certain restrictions that enhance its expansion in the industrial sec- tor such as porosity in the structure and reduced surface quality, in addition to the anisotropy generated by the

1 Introduction Fused deposition modelling (FDM) is one of the most popular layered manufacturing technology processes used for fabricating complex-shaped parts by means of the mechanical extrusion of melted material (i.e. polymer material) through a nozzle. The FDM process uses solid copolymer filaments as a building material, which undergo partial melting within a liquefier at temperatures at or slightly above the polymer melting temperature (i.e. 5°C–10°C), followed by mechanical extrusion through a nozzle. The material is extruded on top of previously formed

clinical medicine (e.g., dental/orthopedic surgery) [ 2 ]. Additive manufacturing technologies include fused deposition modeling (FDM), stereolithography (SLA), Inkjet printing, and selective laser sintering (SLS) [ 3 , 4 , 5 ]. A systematic review of additive manufacturing technology was presented by Ford and Despeisse [ 6 ]. It is reveals that the properties of 3D printed object depend on several printing parameters and can be significantly improved with proper adjustment. However, many difficulties appear in the additive manufacturing such as high cost of the

print multiple copies just like a photocopy machine and run-off three-dimensional products with precise dimensions. Therefore, the development of 3D printing techniques would enable each individual potentially be their own manufacturer as well as their own internet site and power company. Because of those extraordinary benefits, the 3D printing technology has been hailed as the new infrastructure for a Third Industrial Revolution. Among those developed additive manufacturing methods and practical applications, fused deposition modeling (FDM) has been well

Mahapatra* and Anoop Kumar Sood A Study on Dimensional Accuracy of Fused Deposition Modeling (FDM) Processed Parts using Fuzzy Logic Abstract: Fused Deposition Modeling (FDM) is an additive manufacturing technology for rapid prototyping that can build intricate parts in minimal time with least human intervention. The process parameters such as layer thick- ness, orientation, raster angle, raster width and air gap largely influence on dimensional accuracy of
