Dimensional Accuracy Analysis for Desktop 3d Printers for Fused Deposition Modeling (FDM)

Three-dimensional (3D) printing via Fused Deposition Modeling (FDM) technique has gained acceptance in many fabrication arenas due to its outstanding advantages andcurrently there are more than 20 types of desktop 3D printers available in market nowadays. Quality of every printer is the key that drive competitive advantage among the same type of printer and product quality is basically referring to the extent to which printer meet the expectations of customer.This research is an analysis on dimensional accuracyspecific shape and geometries ofproduct printedbyfive (5) types of desktop 3D printers that are commonly used in fabrication industry.The dimension of all 5 product printed by each printer was measured and compared with one another and the result was analyzed thoroughly and finally the best dimensional accuracy of product printed is chosen among the sample studied.The finding results shows that some printers are showing good accuracy in specific shapes and geometries while on other shapes and geometries the high percentage error.
