The Effect of Build Angle on the Mechanical Properties of 3D- Printed Custom Tray Resin Specimens.

The aim of this in vitro study was to evaluate the effect of build angle on the flexural strength (FS), elastic modulus (E), and hardness (VH) of stereolithography (SLA) based 3D-printed custom tray resin. 3D-printed specimens with dimensions of 65.0 mm × 10.0 mm × 3.3 mm ± 0.2 mm were manufactured with different build angles (90, 120, 135, 150, 180 degrees) using custom tray resin. For preparing the specimens in the control groups, the autopolymerizing (AP) resin and the ultraviolet polymerizing (UV) resin were used. FS and E were determined by a three-point bending test, and hardness was evaluated with the VH test. Fracture surfaces were evaluated with scanning electron microscopy (SEM). Statistical analysis of the data was made using a one way ANOVA followed by the Dunnett T3 test. Considering all parameters, the UV group was statistically significantly lower than the other groups. The mean E value of the 90D group was statistically significantly different than those of the 150D group (P=.000) and the 180D group (P=.002). The mean E value of the 120D group was statistically significantly different than those of the 150D group (P=.003) and the 180D group (P=.013). The AP group showed a higher mean VH number (20.20 ±2.08), and the difference was statistically significant compared to the 3D-printed groups (P<.005). Considering its mechanical properties, it was appropriate to arrange the build angles to different degrees when manufacturing reliable custom trays using SLA. 3D printed custom tray production method was a more standard method compared to AP and UV.

Novel sustainable, smart, and multifunctional 4D-printed nanocomposites with reprocessing and shape memory capabilities

Abstract The present paper explores the development of novel recyclable and reprocessable nanocomposites with enhanced shape memory (SM) capability Digital Light Processing 3D printing technology. More specifically, the developed Covalent Adaptable Network is based on polyurethane containing Diels Alder bonds reinforced with carbon nanotubes (CNTs), where the dynamic bonds enable recyclability and reprocessability, whereas CNT addition allows obtaining electrically conductive nanocomposites. In this sense, the nanocomposites exhibited significant Joule heating capabilities, which were used to trigger the SM cycle.&amp;#xD;First, CNT contents and thermal treatments were tuned to optimize SM capabilities in a conventional oven, seeking for obtaining a stable temporary shape at room temperature. Then, the SM capabilities triggered by Joule heating were characterized. Here, the optimized nanocomposites showed excellent shape fixity and recovery ratios (both above 95 %) when triggering the SM by the Joule effect. This heating method was proven to be low energy-consuming (around 1 W), as well as allowing fast, remote, and selective activation, being the latter the ability to trigger the SM in a specific area of the specimen as desired, which was demonstrated with a hand-like proof-of-concept by selectively recovering the permanent shape of each finger.&amp;#xD;Finally, the 3D-printed specimens were turned into powder and reprocessed using a powder processing tool, obtaining a still electrically conductive part with a different geometry given the DA adduct formations.&amp;#xD;In summary, the multifunctional and smart capabilities of the developed nanocomposites make them suitable for applications such as soft robotics or actuators with an extended useful life, promoting sustainability.&amp;#xD;

Concentrated Pre-Vulcanized Natural Rubber Latex Without Additives for Fabricating High Mechanical Performance Rubber Specimens via Direct Ink Write 3D Printing

Direct ink writing (DIW) is an economical, straightforward, and relatively energy-efficient 3D printing technique that has been used in various domains. However, the utilization of rubber latex for DIW remains limited due to its high fluidity and inadequate support, which makes it challenging to meet the required ink rheological characteristics for DIW. In this study, a concentrated pre-vulcanized natural rubber latex (CPNRL) ink with a high solid content of 73% without additives is developed for DIW 3D printing. The CPNRL ink is concentrated using superabsorbent polymer (SAP) beads, which demonstrates good colloidal stability, favorable rheological properties, and superior printability. The impact of printing angles on the mechanical properties of the rubber specimens based on the CPNRL-73 ink is explored in detail, wherein the tensile strength of the specimen printed at a 90° angle reaches an impressive 26 MPa and a strain of approximately 800%, which surpasses the majority of 3D-printed rubber latex specimens. Additionally, the CPNRL ink can be used to print a wide range of intricate shapes, demonstrating its advantages in excellent formability. The preparation of 3D printable ink using the absorption method will expand the application of elastomers in fields such as customized flexible sensing and personalized rubber products.

Investigation on geometric, dimensional accuracy and surface roughness for 3D printed PLA via fused deposition modelling (FDM) process

Fused deposition modeling (FDM) is an advanced additive manufacturing technique known for its precision and repeatability, extensively applied in producing automotive and industrial components. This study employs the Taguchi L9 orthogonal array (OA) approach to optimize process parameters for minimizing dimensional inaccuracies, geometric deviations, and surface roughness (Ra) in polylactic acid (PLA) specimens fabricated as per ASTM D638 Type V standards. Four critical printing parameters: extrusion temperature (ET), infill pattern (Ip), print rate (Rp), and layer height (LH) are investigated, focusing on specimen thickness (Ts), width of the grip section (Wgs), overall length (OL), circularity (Circ), cylindricity (Cyl), surface roughness (Ra), and waviness (Wa). Signal-to-noise (S/N) ratio analysis identified optimal parameter combinations, revealing that Ip, ET, and Rp significantly influence circularity by 39.24%, 37.34%, and 15.19%, respectively. One of the important factors that affect the degree of inaccuracy in cylindricity is the Ip. Gyroid pattern generated the least amount of inaccuracy out of all the patterns that were tested. Layer height (LH) at 0.1 mm was the most critical factor affecting Ra and Wa, while an extrusion temperature of 215°C predominantly influenced Ts. The Ip has the most affected the grip section width. In contrast to expectation, the triangle Ip achieved the minimum width error that was 0.3384%. The Rp of 40 mm/s has the highest impact on the OL deviations. Out of all the other patterns, the Tri-Hexagon (Ip) has made the least contribution to the OL deviations. Rp exhibited a lower contribution to Ra (2.35%) and Wa (12.45%). The results demonstrate the effectiveness of the Taguchi approach in identifying optimal process setups for enhancing the precision, geometric accuracy, and surface quality of 3D-printed specimens.

Impact of Fabrication Techniques and Polishing Procedures on Surface Roughness of Denture Base Resins.

This study aimed to assess the impact of various fabrication techniques and polishing procedures on the surface roughness (Ra) of resin-based materials used in the fabrication of complete dentures. A total of 90 specimens were produced from three different resin materials: heat-polymerized polymethyl methacrylate (PMMA) resin, CAD-CAM milled PMMA resin, and 3D-printed resin (n = 30). Each specimen measured 10 mm in diameter and 2 mm in height. The surface roughness (Ra) values of the specimens were initially determined using a contact profilometer following fabrication. Subsequently, each group of specimens was polished with 600-, 800-, and 1000-grit silicon carbide abrasive papers under running water. A second measurement of the surface roughness (Ra) values was then performed. The data were analyzed statistically using the Kruskal-Wallis test, Mann-Whitney U test, Wilcoxon signed-rank test, and paired samples t-test (p = 0.05). A statistically significant difference was identified between the groups in terms of surface roughness (Ra) prior to the polishing process (p < 0.001). However, no statistically significant difference was observed between the milled and heat-polymerized PMMA base materials following the polishing process. The 3D-printed specimens showed the most notable improvement in surface roughness due to the polishing process. Nevertheless, their surface roughness remained statistically significantly higher compared to the other samples, both before and after polishing (p < 0.001). The fabrication method of complete denture base materials was observed to influence surface roughness. The surface roughness values of the base materials fabricated using the 3D printing method were higher compared to those fabricated with milled and heat-polymerized PMMA resin, both before and after polishing.

Comprehensive analysis of the compressive behavior of Fischer-Koch-S, F-RD, and neovius TPMS cellular structures in 3D-printed PLA specimens

This paper investigates the compression-tested mechanical properties of 3D Polylactic acid (PLA) printed Triply Periodic Minimal Surfaces (TPMS) lattice structures, exploring the impact of varying input parameters. The input parameters included in this study are cellular structure, printing speed, and unit cell size. This study serves as a valuable guide for achieving specific mechanical properties through the selection of optimal parameters. The three input parameters would have a major effect in the overall mechanical properties of the specimens. Four output parameters were studied in this experiment elastic modulus, yield stress, plateau stress, and toughness. A Desirability Function Analysis (DFA) was implanted to achieve the most optimal parameter combination and it was compared to the original parameters. By comparing the mechanical properties of the original nine samples against the predicted optimized parameter, the toughness was increased by 2.15%, elastic modulus increased by 108.33%, yield stress increased by 4% and plateau stress increased by 3.97%.

Origami-inspired auxetic structures: Design and performance in quasi-static and dynamic loading

Auxetic metamaterials have gained attention due to their unique mechanical properties. Integrating origami structures with cellular structures can significantly enhance their energy absorption capacity under mechanical loads. This study develops a novel auxetic structure by combining a curved origami design with the cross-petal auxetic structure. The structure’s behavior under in-plane compressive loading is analyzed using finite element simulations and validated through experimental testing of 3D-printed specimens. The effects of loading rates (quasi-static, low-, medium-, and high-velocity) and geometrical parameters on energy absorption are examined through parametric studies. Structure grading, based on unit cell wall thickness, is also investigated to enhance performance. Finally, the proposed structure’s energy absorption is compared with two common auxetic metamaterials (reentrant and chiral) under various loading conditions. Results indicate deformation becomes more localized with increased loading velocity, with the proposed design achieving a 70% improvement in energy absorption over non-origami designs and a 16% enhancement through grading. The main contribution of this study is the creation of a hybrid structure combining curved origami and cross-petal auxetic designs, achieving a 70% improvement in energy absorption. The dual plateau stress region and graded design further enhance performance, positioning it as an innovative solution for impact protection and soft robotics. The proposed structure exhibits up to 7.56 times higher specific energy absorption under quasi-static loading compared to reentrant and chiral designs, maintaining superior performance at higher loading velocities.

Sustainable Multi-Cycle Physical Recycling of Expanded Polystyrene Waste for Direct Ink Write 3D Printing and Casting: Analysis of Mechanical Properties.

This work investigates the sustainable reuse of expanded polystyrene (EPS) waste through a multi-cycle physical recycling process involving dissolution in acetone and subsequent manufacturing via Direct Ink Write (DIW) 3D printing and casting. Morphology and mechanical properties were evaluated as a function of the manufacturing technique and number of dissolution cycles. Morphological analysis revealed that casted specimens better replicated the target geometry, while voids in 3D-printed specimens aligned with the printing direction due to rapid solvent evaporation. These voids contributed to slightly reduced stiffness in 3D-printed specimens compared to casted ones, particularly for transverse printing orientation. The defoaming process during dissolution significantly increased the density of the material, as well as removed low molecular weight additives like plasticizers, leading to a notable enhancement in stiffness. Successive dissolution cycles led to increased removal of plasticizers, enhancing stiffness up to 52 times (cast), 42 times (longitudinally printed), and 35 times (transversely printed) relative to as-received EPS waste. The glass transition temperature remained unchanged, confirming the preservation of polymer integrity. This work highlights the potential of EPS inks for sustainable, multi-cycle recycling, combining enhanced mechanical performance with the flexibility of 3D printing for complex, cost-effective designs, aligning with circular economy principles.

Effects of Fiber Orientation on the Bearing Strength of 3D-Printed Composite Materials Produced by Fused Filament Fabrication.

Among 3D printing technologies, fused filament fabrication (FFF) is a fast, simple, and low-cost technology that is being explored in a variety of industries. FFF produces composites using thermoplastic filaments, limiting the applicability of welding. Therefore, mechanical fastening is required to join FFF composites with metals or dissimilar materials. The strength characteristics of fastened joints vary with fiber orientation, necessitating further research. Additionally, in the case of FFF, the strength trends may differ from those of traditional composites due to the voids and curved surfaces formed during the process. In this study, 3D-printed composite specimens with seven different fiber orientations were fabricated using the Markforged X7™ printer. The bearing strength and failure modes were analyzed as a function of fiber orientation. Unlike traditional composites, specimens with a ±15° fiber orientation exhibited a 7.56% higher bearing strength compared to those with a 0° orientation. However, the fracture energy of the ±15° specimens was 39.56% lower. Specimens with fiber orientations between 0° and ±45° primarily showed bearing failure modes, while those with orientations from ±60° to 90° exhibited net-tension failure modes. These results confirm that when using manufacturing methods like FFF, the strength trends vary with fiber orientation compared to traditional composites. Further research is necessary to optimize fiber orientation and improve structural performance.

Assessing shear bond strength of various surface treatments of 3D-printed provisional material with bis-acryl relining material

ObjectiveMarginal adaptation of the provisional restoration often requires relining from relining materials. This study determined the effects of surface treatments on the shear bond strength (SBS) between 3D-printed provisional and bis-acryl relining materials.Materials and methodsThe 3D-printed provisional specimens (9 × 9 × 2 mm3) were prepared using methacrylate-based material. Five test groups (n = 15) based on surface treatments were evaluated; (1) no treatment (CT), (2) ethanol (ET), (3) universal adhesive; CLEARFIL TRI-S BOND Universal Quick (UA), (4) airborne-particle abrasion with 50 μm aluminum oxide particles (AA), and (5) airborne-particle abrasion followed by universal adhesive (AA-UA). The specimens were bonded with relined bis-acryl resin material and left at room temperature for 24 h, allowing the complete polymerization. Then, shear bond strength was performed using a universal testing machine with a knife-edge blade parallel to the bonded surface at a crosshead speed of 1 mm/min until failure occurred. The fracture surfaces were examined under stereomicroscopy (20X) and scanning electron microscopy (50X).ResultsThe CT group had the lowest shear bond strength (1.92 ± 0.26 MPa), which was no statistically significant difference from ET (2.11 ± 0.23 MPa). The significantly highest shear bond strength was obtained from AA-UA (14.39 ± 1.07 MPa) (p < 0.05), followed by AA (6.39 ± 0.59 MPa) and UA (3.34 ± 0.21 MPa), respectively. Failure modes obtained were varied, with mixed and cohesive failures in AA-UA (46.6% mixed failures) and AA groups (66.6% mixed failure) whereas primarily adhesive failures were observed in CT (93.5%), ET (86.6%), and UA groups (86.6%).ConclusionsWithin the limitation of this study, the optimal bond strength was obtained when airborne-particle abrasion and universal adhesive were applied on the 3D-printed provisional material and relined with bis-acryl relining material.

In-plane impact characteristics of missing rib type anti-tri-chiral honeycomb

Previous studies have demonstrated that antichiral honeycomb materials exhibit superior mechanical properties and energy-absorbing characteristics compared to conventional hexagonal honeycomb materials. To further explore the impact resistance of antichiral honeycomb and enhance its energy-absorbing capacity, this paper introduces a novel missing rib type anti-tri-chiral honeycomb (MATCH). Derived from the original anti-tri-chiral honeycomb (ATCH), the MATCH design replaces the V-element cell wall with a circular cell wall. This paper conducts quasi-static compression experiments on 3D-printed MATCH specimens, employing a method that integrates experimental data and numerical simulation. The validity of the MATCH model is confirmed using the ABAQUS simulation software. The deformation modes of MATCH and ATCH are analyzed. Subsequently, through parametric analysis, it is observed that when φ =110° and the ligament-to-truss ratio L/r = 2, MATCH increases the plateau stress and specific energy absorption (SEA) by 162.96% and 176.09%, respectively, compared to ATCH, with a mere 7.8% relative density error. This study serves as a reference for improving energy absorption and optimizing the design of structures using future antichiral honeycomb materials.

Metamaterial structure impacts on stress and bending fatigue lifetime of additive-manufactured 3D-printed PLA specimens

Investigation of 3D Printed Self-Sensing UHPC Composites Using Graphite and Hybrid Carbon Microfibers.

This paper explores the development of 3D-printed self-sensing Ultra-High Performance Concrete (UHPC) by incorporating graphite (G) powder, milled carbon microfiber (MCMF), and chopped carbon microfiber (CCMF) as additives into the UHPC matrix to enhance piezoresistive properties while maintaining workability for 3D printing. Percolation curves were established to identify optimal filler inclusion levels, and a series of compressive tests, including quasi-static cyclic, dynamic cyclic, and monotonic compressive loading, were conducted to evaluate the piezoresistive and mechanical performance of 29 different mix designs. It was found that incorporating G powder improved the conductivity of the UHPC but decreased compressive strength for both mold-cast and 3D-printed specimens. However, incorporating either MCMF or CCMF into the UHPC resulted in the maximum 9.8% and 19.2% increase in compressive strength and Young's modulus, respectively, compared to the plain UHPC. The hybrid combination of MCMF and CCMF showed particularly effective in enhancing sensing performance, achieving strain linearity over 600 με. The best-preforming specimens (3G250M250CCMF) were fabricated using 3 wt% of G, 0.25 wt% of MCMF, and 0.25 wt% of CCMF, yielding a maximum strain gauge factor of 540, a resolution of 68 με, and an accuracy of 4.5 με under axial compression. The 3D-printed version of the best-performing specimens exhibited slightly diminished piezoresistive and mechanical behaviors compared to their mold-cast counterparts, yielding a maximum strain gauge factor of 410, a resolution of 99 με, and an accuracy of 8.6 με.

Gradient 2D re-entrant cores for sandwich structures under low-velocity impact

Auxetic metamaterials, known for their unusual properties, are being explored as cores for sandwich structures to improve impact resistance. This study investigated the low-velocity impact response of sandwich panels with various core designs using finite element method (FEM) and experiments on 3D-printed specimens. These cores include pure honeycomb, pure auxetic, and gradient variations with controlled gradients of Poisson’s ratio, transitioning from negative to positive (NTP), positive to negative (PTN), negative-to-positive-to-negative (NTPTN), and positive-to-negative-to-positive (PTNTP). These gradients were achieved by adjusting the unit cell angle within the core. Under quasi-static indentation, the gradient PTN design improved energy absorption by 26% compared to the honeycomb structure, while the gradient NTP structure showed a 9% improvement over the auxetic core. As for the impact tests, the gradient NTP and PTN structures significantly enhanced the indentation resistance of auxetic and honeycomb structures by 21.3% and 6.5%, respectively. Interestingly, while the optimal core for peak energy absorption varied with impact velocity, gradient structures generally provided superior energy absorption, particularly at lower velocities. FEM results at initial impact velocities of 10, 15, 20 m/s confirmed that structures having negative Poisson’s ratio at their top layer exhibited the lowest penetration depth. Additionally, gradient structures, particularly NTP and NTPTN, demonstrated superior energy absorption capability compared to purely auxetic or honeycomb structures, especially at lower velocities. The study highlights the benefits of utilizing gradient auxetic metamaterial cores in high-performance sandwich structures for impact resistance applications. These structures showed minimal localized damage, reduced densification risk due to uniform crushing, and lower penetration depth.

Temperature–amplitude spectrum for early full-field vibration-fatigue-crack identification

A dynamic structure under vibration loading within its natural frequency range can experience failure due to vibration fatigue. Understanding the causes of such failure requires pinpointing the initiation time and location of fatigue cracks, tracking their propagation, and identifying the frequency range of critical stress responses. This research introduces a novel, thermoelasticity-based method – the Temperature–Amplitude Spectrum (TAS) method – for early-stage, full-field, and non-contact crack detection that operates during uninterrupted vibration testing. This method leverages high-speed infrared imaging to analyze the specimen’s temperature–amplitude spectrum, capturing comprehensive crack-related information, including initiation and propagation, in real time. Experimentally validated on both 3D-printed polymer and aluminum specimens, the TAS method accurately identified crack locations and paths without complex adjustments to the experimental setup or data processing. This new approach advances vibration-fatigue testing by enabling reliable, high-resolution crack detection and analysis while remaining computationally efficient.

Utilisation of By-Product Phosphogypsum Through Extrusion-Based 3D Printing.

Phosphogypsum (PG) is a phosphate fertiliser by-product. This by-product has a low level of utilisation. Calcium sulphate is dominated in PG similar to gypsum and, therefore, has good binding properties (similar to natural gypsum). However, the presence of water-soluble phosphates and fluorides, an unwanted acidic impurity in PG, makes PG unsuitable for the manufacture of gypsum-based products. In this study, the binding material of PG (β-CaSO4·0.5H2O) was produced from β-CaSO4·2H2O by calcination. To neutralise the acidic PG impurities, 0.5 wt% quicklime was added to the PG. In the construction sector, 3D-printing technology is developing rapidly as this technology has many advantages. The current study is focused on creating a 3D-printable PG mixture. The 3D-printing paste was made using sand as the fine aggregate and a binder based on PG. The results obtained show that, despite the low degree of densification, 3D printing improves the mechanical properties of this material compared to cast samples. The 3D-printed specimens tested in [u] direction reached the highest compressive strength of 950 kPa. The cast specimens showed a 17% lower compressive strength of 810 kPa. The 3D-printed specimens tested in the [v] and [w] directions reached a compressive strength of 550 kPa and 710 kPa, respectively.

Comparative Analysis of Modern 3D-Printed Hybrid Resin-Ceramic Materials for Indirect Restorations: An In Vitro Study.

The study investigated the impact of aging on surface roughness, color stability, and biocompatibility of hybrid resin-ceramic materials. A total of 225 specimens were produced from three three-dimensional (3D)-printed (HarzLabs Dental Sand Pro (HL), BEGO VarseoSmile Crown plus (BV), Voco V-Print c&b temp (VV)) and one milled material (Voco Grandio Blocs (VG)). Specimens were grouped into untreated, polished, and glazed surfaces. 5000 thermal cycles simulated aging. Surface roughness and color stability were analyzed, and surface topography was observed using scanning electron microscopy (SEM). Biocompatibility was evaluated with L929 cells. Surface roughness differed significantly between untreated and other groups, with no changes before and after artificial aging. Untreated milled samples were significantly smoother than 3D-printed ones. SEM analysis revealed roughest surfaces in untreated 3D-printed specimens. Polished and glazed specimens were smoother than untreated ones. Color values showed significant differences between untreated and treated/aged groups. No material showed cytotoxicity. In summary, untreated VG was smoother than 3D-printed materials, but polishing and glazing reduced roughness to levels comparable to VG. Surface treatments induced color changes, with glazing causing more changes than polishing. Aging affected color stability and biocompatibility but not surface roughness. All materials showed acceptable color changes and good biocompatibility.

Impact of surface roughness on the formation of necking instabilities in additive manufactured porous metal plates subjected to dynamic plane strain stretching

This paper investigates the influence of surface roughness on multiple necking formation in additive manufactured porous ductile plates subjected to dynamic plane strain stretching. For this purpose, we have developed a computational model in ABAQUS/Explicit which includes surface texture and discrete voids measured from 3D-printed metallic specimens using optical profilometry and X-ray tomography analysis, respectively. The mechanical behavior of the material is described using an elastic–plastic constitutive model, with yielding defined by the isotropic von Mises criterion, an associated flow rule, and a power-law function for the yield stress evolution which depends on plastic strain, plastic strain rate, and temperature. The finite element calculations have been conducted across a broad range of strain rates, from 5000s−1 to 50000s−1, to explore the interactions among inertia, surface roughness, and porosity in determining the necking pattern that emerges in the plates at large strains. The finite element results show that surface roughness induces perturbations in the deformation field of the specimen, which lead to early necking localization, while the location and number of necks formed are primarily controlled by the porous microstructure and the loading rate. The results for the neck spacing have shown quantitative agreement with the analytical stability analysis predictions and the unit-cell finite element calculations reported by Rodríguez-Martínez et al. [1]. Moreover, integrating discrete voids into simulations that already account for surface roughness results in a minor reduction in necking strain: surface roughness and porosity demonstrate similar quantitative impacts on necking ductility, which is primarily influenced by inertia effects at the highest strain rates studied. To the best of the authors’ knowledge, this paper presents the first calculations that explore dynamic plastic localization in additive manufactured metals, incorporating actual surface roughness and explicit void representation derived from experimental measurements. This work marks progress in the analysis of 3D-printed structures under impact loading, aiming to understand and predict the mechanics influencing their energy absorption capacity at high strain rates.

Lattice Structures-Mechanical Description with Respect to Additive Manufacturing.

Lattice structures, characterized by their repetitive, interlocking patterns, provide an efficient balance of strength, flexibility, and reduced weight, making them essential in fields such as aerospace and automotive engineering. These structures use minimal material while effectively distributing stress, providing high resilience, energy absorption, and impact resistance. Composed of unit cells, lattice structures are highly customizable, from simple 2D honeycomb designs to complex 3D TPMS forms, and they adapt well to additive manufacturing, which minimizes material waste and production costs. In compression tests, lattice structures maintain stiffness even when filled with powder, suggesting minimal effect from the filler material. This paper shows the principles of creating finite element simulations with 3D-printed specimens and with usage of the lattice structure. The comparing of simulation and real testing is also shown in this research. The efficiency in material and energy use underscores the ecological and economic benefits of lattice-based designs, positioning them as a sustainable choice across multiple industries. This research analyzes three selected structures-solid material, pure latices structure, and boxed lattice structure with internal powder. The experimental findings reveal that the simulation error is less than 8% compared to the real measurement. This error is caused by the simplified material model, which is considering the isotropic behavior of the used material PA12GB (not the anisotropic model). The used and analyzed production method was multi jet fusion.
