The article presents the results of technical-economical study regarding optimization fused deposition modeling (FDM) parameters (the height layer deposited in one pass-Lh and filling percentage-Id) for manufacture Polyethylene Terephthalate Glycol (PETG) Acrylonitrile Styrene Acrylate (ASA) parts. To carry out this study, was used fundamental principle value analysis, which consists maximizing ratio between Vi Cp, where represents mechanical characteristic, Cp production cost. show that tensile specimens made PETG, parameter significantly influences Vi/Cp ratios is pass, (Lh), case compression percentage (Id). In manufactured via FDM from ASA, decisively By performing process with multiple responses, we identified optimal manufacturing parts PETG ASA: Lh = 0.20 mm, percentage, Id 100%.

This paper presents the results of research on technical–economic optimization FDM parameters (Lh—layer height and Id—infill density percentage) for manufacture tensile compression samples from recycled materials (r) PETG (polyethylene terephthalate glycol) ASA (acrylonitrile styrene acrylate) in context transition to a circular economy. To carry out our study, fundamental principle value analysis was used, which consists maximizing ratio between Vi Cp, where represents mechanical characteristic (tensile strength or compressive strength) Cp production cost. The this study showed that, case manufactured by (rPETG), parameter that significantly influences Vi/Cp ratios is Lh (the layer), while additively (rASA), decisively Id infill percentage). In (rPETG) signified Following parameters, using multiple-response optimization, we identified optimal parts rPETG rASA: = 0.20 mm 100%. demonstrated use plastics lends itself consumption model based

Materials, Год журнала: 2024, Номер 17(12), С. 2928 - 2928

Опубликована: Июнь 14, 2024

In order to obtain a lightweight, high-strength, and customizable cellular structure meet the needs of modern production life, mechanical properties four thickness gradient honeycomb structures were studied. this paper, types specimens with same porosity different Poisson's ratios designed manufactured by using SLA 3D-printing technology, including honeycomb, square quasi-square re-entrant structures. Based on plane compression failure mode analysis these specimens, is applied structure, structural forms are formed. The experimental results show that exhibits better than uniform wall thickness. studied whole can be significantly improved increasing cell walls at upper lower ends structure. thickness, arrangement order, shape, ratio all have significant impact specimens. These provide an effective basis for design application in future.

Ingenierias, Год журнала: 2025, Номер 28(98), С. 31 - 41

Опубликована: Янв. 31, 2025

Dado el continuo avance de la tecnología impresión 3D y creciente interés en desarrollar prototipos o productos con propiedades mejoradas, este estudio se centra evaluación las mecánicas del acrilonitrilo-butadieno-estireno (ABS). Se fabricaron probetas ABS bajo diferentes condiciones impresión, cuales fueron evaluadas mediante un diseño experimentos ensayos tensión para identificar los parámetros óptimos que maximizan resistencia a material. Adicionalmente, realizó análisis mecánico dinámico (DMA) probeta mejores evaluando su comportamiento viscoelástico función temperatura. Los resultados DMA muestran una temperatura transición vítrea alrededor 123°C, indicando máxima disipación energía. Por encima 160°C, material mostró viscoso asociado al inicio flujo, información clave optimizar procesos como inyección, extrusión e 3D. Este enfoque integral combina técnicas caracterización mecánica viscoelástica, permitiendo establecer relación entre desempeño ABS, contribuyendo eficiente aplicaciones.

ABSTRACT This study investigates the optimization of 3D‐printed polylactic acid (PLA) and hydroxyapatite (HA) composites for biomedical applications, focusing on enhancing mechanical properties through process parameter surface modification. The response methodology (RSM), along with post hoc statistical validation using Tukey's HSD test, was employed to evaluate influence nozzle temperature (200°C–240°C), layer height (0.1–0.3 mm), HA filler ratio (3–9 wt%) compressive strength both untreated chemically treated composites. Silane treatment applied improve interfacial bonding, resulting in a 5%–7% increase compared samples. optimal conditions (240°C, 9% HA, 0.3 mm thickness) yielded maximum 75.35 MPa 71.42 Statistical analysis confirmed that thickness content significantly influenced performance. Contour plots 3D surfaces were also incorporated visualize interactions. Comparison other techniques demonstrated RSM effectively minimized experimental runs while achieving superior properties. These findings suggest modified PLA/HA are promising candidates load‐bearing applications.
