MANUFATURA ADITIVA: COMPARATIVO DE RESISTÊNCIA MECÂNICA DE ROSCAS FABRICADAS POR FDM EM PLA E ABS

: The objective of this work is to study the mechanical tensile strength of the internal threads in specimens manufactured in PLA and ABS from additive manufacturing by FDM: Fused Deposition Modeling. Test specimens measuring 30 x 30 x 20 mm were manufactured in PLA and ABS with a 3D printer model Ender 3 V2. The through hole of the test specimens has measurements M12 x 1.75. The varied parameters in the research were: fillings (p), number of walls (w) and height of the layers (h), to enable the understanding of how the mechanical resistance of the material is affected. PLA, despite having a lower resistance of the raw material than ABS, resulted in higher values of mechanical resistance in all tested conditions.
