EFFECT OF PRINTING SPEED ON FDM 3D-PRINTED PLA SAMPLES PRODUCED USING DIFFERENT TWO PRINTERS

Today, 3D manufacturing technologies are shown as candidates to replace traditional technologies. In this direction, many studies carried out reduce the disadvantages of The first few these are; high production cost, slow speed, and lower strength values produced product compared methods. Increasing or decreasing printing which is one 3d parameters, appears a parameter that will directly affect costs product. For reason, it important determine effects may occur on mechanical properties by changing speed in terms choosing according intended use study, effect desktop Fused Deposition Modelling (FDM) was investigated. Tensile test samples were using Polylactic Acid (PLA) material at seven different speeds two printers operated without bed heating. mass, hardness, surface roughness, porosity determined. Fractured surfaces analyzed Scanning electron microscopy (SEM) images. results show an increase decreases top tensile increases porosity, arithmetic average roughness products with both printers.
