A Comparative Study of various AM Technologies Based on Their Accuracy

The paper deals with the comparison of various Additive Manufacturing technologies regarding their manufacturing accuracy. Similar machines using the Fused Deposition Modelling technology are employed and described. A special specimen was designed for the purpose of accuracy assessment, and investigated not only with respect to the dimension tolerances but also regarding the possibility to assemble/disassemble specific geometric interferences. Similarly, appropriate criteria were proposed and used to compare specimens made by various machines. In the conclusion, the resulting performance table, including the obtained data, is presented and described.
