“…The bed temperature for the first layer and the subsequent printed layers was imposed equal to 30 • C. From Figure 1, the nominal or target geometrical data were: overall length of the specimen in the x direction equals 180 mm, length of the reduced section in the x direction equals 57 mm, reduced section width in y direction equals 13 mm, thickness of the specimen in the z direction equals 5 mm. The target value for the weight was 18.18 g and it was obtained by considering the volume of the specimen as given by the CAD model, and then multiplying it for the infill density equals 1 and for the mass density of the PLA equals 1.25 g/cm 3 . The real geometrical data for each produced specimen were measured by means of a digital caliper, the weight of each specimen was determined using a digital weight scale.…”

“…The brilliant future of AM technology was discussed in Lu et al [2] where its enormous potential was clearly indicated and several applications were shown. Carlier et al [3] proposed a study to investigate the possibility to produce implantable devices via the 3D FDM technology. The physical properties of these elements were difficult to be determined and they depended on the deposition temperature, deposition rate and layer thickness used in the printing process.…”

In this paper, polymeric specimens are produced via the Fused Deposition Modelling (FDM) technique. Then, experimental tensile and compression tests are conducted to evaluate the main mechanical properties of elements made of PolyLacticAcid (PLA) material. A standardized characterization test method for FDM 3D printed polymers has not been developed yet. For this reason, the ASTM D695 (usually employed for polymers produced via classical methods) has been here employed for FDM 3D printed polymers after opportune modifications suggested by appropriate experimental checks. A statistical analysis is performed on the geometrical data of the specimens to evaluate the machine process employed for the 3D printing. A capability analysis is also conducted on the mechanical properties (obtained from the experimental tests) in order to calculate acceptable limits useful for possible structural analyses. The Young modulus, the proportional limit and the maximum strength here defined for PLA specimens allow to confirm the different behavior of FDM printed PLA material in tensile and compressive state. These differences and the calculated acceptable limits for the found mechanical properties must be considered when this technology will be employed for the design of small structural objects made of PLA, as in the present study, or ABS (Acrilonitrile Butadiene Stirene). From the statistical and capability analysis, the employed printing process appears as quite stable and replicable. These types of research together with other similar ones that will be conducted in the future will allow to use polymeric materials and the FDM technique to produce small structural elements and also to carry out the appropriate verifications.

Fused Filament Fabrication (FFF) is an Additive Manufacturing process popularized in the last decade due to its easiness of use and lower costs. However, despite its increasing popularity, the process itself has several gaps in knowledge, hindering further uses on more advanced objects. Also, the freedom of design allows significant variances in the printed parts, many influencing production and mechanical properties. This work studies the influences of the infill patterns in the mechanical response of printed parts. Using poly (lactic acid) (PLA), a widely used polymer in FFF process, the mechanical responses of parts printed with different infill patterns were analyzed. Rectilinear, Honeycomb, Triangle and Grid patterns were tested on impact resistance and tensile strength. Additionally, samples masses were measured and compared to the mechanical response. Results shown significant differences in the on tested properties. Tensile strength varied from 2.4 to 1.1 MPa, and impact resistance from 3.8 to 1.5 kJ/m² Also, measured mass was found to be significantly higher on the Honeycomb pattern. Considering mechanical response from both tensile and impact tests along with printed mass, Rectilinear pattern can be considered the most advantageous from the economic point of view.

Abstract: Additive Manufacturing termed by ASTM standard referred to in short as, the technology of fabricating a model based on creating a three-dimensional Computer-Aided Design structure. In the context of developing a product from digital data directly, widely involved various technologies. Amongst them, one being Fused Deposition Modelling (FDM) which supervises the principle of AM, is widely known for developing a polymer-constructed sturdiest range of materials or parts are having operative mechanical properties. Even though, the main problem exaggerates that, the quality of the output still denies due to which void parts are created from bubbles trapped leading to failure of parts under mechanical stresses. Since with 15% infill, stronger parts are estimated and their mechanical properties are studied. Since the work signifies the influence of 15% infill on mechanical properties in estimating stronger products by layered addition process. The experimental methodology is based on structural infill parameters determining goal in achieving and studying material mechanical properties.
