Abstract FFF (Fused Filament Fabrication) prototyping method is mostly used in the fabrication of 3D complex geometric shapes. Layer by layer deposition technology offers a wide range shapes for plastic parts. The mechanical characteristics manufactured parts depends on material and printing parameters. studies conducted this paper show influence parameters tensile properties ABS (Acrylonitrile...

This study aims to determine the compression strength of Fused Deposition Material (FDM) additive manufacturing with parameters in different layer thicknesses between 0.10 – 0.35 mm. The specimen process refers ASTM D695 Standards ABS (acrylonitrile butadiene styrene) and PLA (polylactic acid) materials. Based on test results, highest is found 0.15 mm thickness material a yield value 66.78 MPa....

The variation of the monomeric friction coefficient of styrene butadiene copolymer (SBR) and natural rubber (NR) with various degrees of cure was analyzed. Samples with different levels of cure were prepared. Loss tangent measurements of the samples were performed by means of a damped torsion pendulum between 173 K and 373 K. Data were analyzed in the frame of the Kloczkowsky, Mark and Frisch m...

co2/ch4 gas separation is a very important applicatable process in upgrading the natural gas and landfil gas recovery. in this work, to investigate the membrane separation process performance, the gas permeation results andco2/ch4 separation characteristics of different prepared membranes (via blending different molecular weights of polyethylene glycol (peg) as a modifier with acrylonitrile-but...
