Preparation of Hydrophobic Surface on PLA and ABS by Fused Deposition Modeling

In-vitro evaluation of Polylactic acid (PLA) manufactured by fused deposition modeling

BACKGROUND With additive manufacturing (AM) individual and biocompatible implants can be generated by using suitable materials. The aim of this study was to investigate the biological effects of polylactic acid (PLA) manufactured by Fused Deposition Modeling (FDM) on osteoblasts in vitro according to European Norm / International Organization for Standardization 10,993-5. METHOD Human osteobl...

Finishing of ABS-M30 Parts Manufactured with Fused Deposition Modeling With Focus on Dimensional Accuracy

Fused Deposition Modeling (FDM) parts are prone to process-related rough and wavy surfaces with stair-stepping effects whenever the parts produced have sloped or rounded geometries. These stair-stepping effects can be reduced by using a smaller slice height, but complete elimination is not possible. In this paper, FDM parts manufactured with the material ABS-M30 are finished using mass finishin...

Curved Layer Fused Deposition Modeling

Current Fused Deposition Modeling (FDM) technologies deposit material as flat layers. The result is a “stair-case” effect on non-vertical or horizontal surfaces, and compromised part strength because of weakness between the laminations. This paper describes a FDM method through which layers of build material are deposited as curved layers following the shape of the part, thus removing the stair...

Dynamic Mechanical Properties of ABS Material Processed by Fused Deposition Modelling

This paper presents a study of dynamic mechanical properties of Fused Deposition Modelling (FDM) rapid prototyping processed material Acrylonitrile butadiene styrene (ABS). It involves the measurement of modulus and damping properties of the material as it is deformed under periodic stress. In this study, frequency sweep is performed in DMA 2980 equipment to determine modulus, damping and visco...
