Methods of Improving Part Accuracy During Rapid Prototyping

Improving part quality during rapid prototyping is the important problem. The part errors during rapid prototyping is classified in dimension error, shaped error and roughness of surface. The shaped errors have many forms in fused deposition modeling (FDM), largely including warpage deformation, stair-stepping effect, and so on. There are several reasons for the errors, including principle, process and equipment. The reasons inducing these errors are analyzed, and the measures improving part accuracy are proposed.
