Abstract In this paper, for the first time, role of manufacturing parameters fused deposition modeling (FDM) on shape memory effect (SME) is investigated by design experiments. PLA-TPU blend with a weight composition 30:70% processed melt mixing and then extruded into 1.75 mm filaments 3D printing via FDM. SEM images reveal that TPU droplets are distributed in PLA matrix, immiscible matrix-droplet morphology evident. Box-Behnken (BBD), as an experimental response surface method (RSM), implemented to fit model between variables responses. The shell, infill density, nozzle temperature selected variables, their effects loading stress, recovery fixity, ratio studied detail. An analysis variance (ANOVA) applied estimate importance each parameter output assess fitness presented model. ANOVA results high accuracy parameters. Infill density had greatest least roles properties, respectively. Also, values fixity were obtained ranges 58–100% 53–91%, Despite many researches 4D PLA, low ductility at room stress relaxation rate its weakness, which covered adding research. Due lack similar outcomes specialized literature, paper likely fill gap state-of-the-art problem supply pertinent data instrumental FDM functional polymers less material consumption.

Fused Deposition Modeling (FDM) is an additive manufacturing technology that has emerged as a promising technique for fabricating 3D printed polymers. It gained attention recently due to its ease of use, efficiency, low cost, and safety. However, 3D-printed FDM components lack sufficient strength compared those made using conventional methods. This can be mainly attributed high porosity sinterability layers then the characteristics polymer used in process or itself. Regarding characteristics, there are two main types reinforcing fibers: discontinuous (short) continuous. Continuous-fiber reinforced composites becoming popular various industries their excellent mechanical properties. Since continuous fibers have more positive effect on increasing parts, this article focuses primarily long fibers. In addition different mechanisms been developed introduced address issue insufficient parts. comprehensively explains mechanisms: in-situ fusion ex-situ prepreg. also provides relevant examples these elements. Additionally, some other less frequently utilized discussed. Each mechanism own advantages disadvantages, indicating further development modification needed increase parts comparable produced traditional

Powder bed fusion (PBF) is recognized as one of the most common additive manufacturing technologies because its attractive capability fabricating complex geometries using many possible materials. However, quality and reliability parts produced by this technology are observed to be crucial aspects. In addition, challenges PBF-produced hot issues among stakeholders still insufficient meet strict requirements high-tech industries. This paper discusses present state art in PBF technological challenges, with a focus on selective laser melting (SLM). The review work focuses mainly articles that emphasize status metal-based AM, study primarily limited open-access sources, special attention given process parameters flaws determining factor for printed part reliability. Moreover, defects due an unstrained parameter SLM those needed monitor sustain components encompassed.

The process of sintering involves applying pressure and heat to the materials without melting them in order fuse particles together into a solid mass. fusion between particle are also known as interparticles necking which plays an important role producing high-density products. Increasing size will allow formation smaller pore sizes help produce stronger higher hardness materials. essential high porosity products that commonly used for medical applications still required tensile value hardness. For this, proper parameters were larger growth. To get better understanding this matter, effect powder processing be reviewed article. different processes such conventional sintering, microwave selective laser melting, others discussed paper well.
