Effect Of Fused Deposition Modeling (FDM) Parameters On The Warpage And Different Composition Polylactic Acid/Ethylene-Vinyl Acetate Blend

Fused Deposition Modelling (FDM) is a popular 3D printing method to create a part with complicated design and low cost. A common issue that occurs during FDM printing process is the warpage of the part which contributes to inadequate mechanical properties and reduced dimensional accuracy. This res...
