“…Since 3D printing consumes a significant amount of filament and time, using the minimum number of specimens in mechanical tests is wanted. Therefore, besides the average coefficient of variation (CV ), another index can assist the choice of the proper geometry (standard), which is given by the ratio between the number of specimens to be taken to calculate the mean mechanical data (10) and the number of broken tested specimens to obtain 10 valid results (NS 10 ), Equation 2. This index is hereafter called tested specimen efficiency (E TS ).…”

“…In MEX or FDM, also known as Fused Filament Fabrication (FFF), a plastic filament is melted and deposited layer by layer to create 3D objects from a digital model. Common filaments include ABS, PLA, PETG, Nylon, PC, and TPE 10 . PLA is widely used due to its biodegradability and suitable mechanical properties 11,12 .…”

This study investigated the influence of specimen geometry on the mechanical properties of 3D‐printed parts by material extrusion (MEX). Four widely used technical standards were evaluated (ASTM D638, ASTM D3039/D3039M‐14, ISO 527/2, and ISO 37), and all possible geometries were tested. The specimens were subjected to uniaxial tensile loading using a universal testing machine to obtain the mechanical properties of ultimate tensile strength, yield strength, and Young modulus. Mean, , and values, as well as (number of specimens tested to reach at least 10 valid data) are geometry‐dependent. A critical analysis of these data allowed proposing the standard evaluation index () of the specimen geometry (standard) based on data variance and test efficiency to achieve valid data. The results indicate that ASTM D638 performed better than any other standard. For investigations involving the mechanical properties of tensile strength Types I and II (ASTM D638) are the most recommended specimens geometry (standard) for 3D MEX printing because it combines the lowest with the minimum . By following it, researchers and material suppliers can ensure accurate and reliable assessments of the mechanical properties of 3D‐printed parts, contributing to increased safety, reliability, and quality in additive manufacturing.

“…El conjunto de polímeros termoplásticos utilizados en FDM pueden ser clasificados en dos grupos en función de la ordenación de sus cadenas poliméricas, semicristalinos y amorfos, y en tres grupos dependiendo de las aplicaciones a las que se pretenden destinar las piezas fabricadas [73], tal y como se muestra en la Figura 2.18.…”
