The diffusion of Fused Deposition Modeling (FDM) was recently boosted by the expiration FDM patent and subsequent worldwide development low cost machines a huge number small companies. In most cases, are worth what they cost. Thus performance expensive industrial systems is better than that machines, also known as 3D printers. this paper benchmarking carried out between Dimension EliteTM Stratasys TouchTM Bits from Bytes (BFB). study comparison based on reference part designed to fit into...
Nowadays, 3D printing is recognized as one of the key technologies that enables distributed manufacturing adoption. However, inexperienced people might perceive this technology far from easy user-usability because evident aesthetic defects on printed parts. In paper, an indicator-based methodology proposed for assessment and ranking capability printers by evaluating ability a printer to reproduce reference part without defects. The includes several geometric features characterize most...
Additive manufacturing (AM) processes allow producing the complex components in a layerwise fashion. The complexity includes design of lighter and stronger by using lattice structures that can be quickly realized through AM technologies. However, mechanical behaviour is not completely known, especially post-treated state. Thus, this work aims to explore effect post-treatment on compressive strength specimens with structures. samples are produced Ti-6Al-4V powder processed Electron Beam...
Laser Powder-based Directed Energy Deposition (LP-DED) process is a cutting-edge Additive Manufacturing (AM) technology for metal part repair and production. The disruptive potentialities of LP-DED are nowadays limited by the difficulty in identification optimized set parameters, typically obtained from long expensive experimental trials. In this work, thermal simulation tool able to predict material deposition behaviour developed using finite element code. An original method defined model...
Additive Manufacturing is a key enabling technology for Industry 4.0 and the Green Deal, allowing more efficient resources exploitation while providing innovative design to critical components. Electron Beam Powder Bed Fusion (EB-PBF) an edge many sectors, i.e. aerospace, medical, automotive. The control of surface finish by topography measurements essential engineer functional properties, whose specifications are application specific. This works investigates effect thin-wall orientation...
Additive manufacturing (AM) technology has great potential in complex internal channels for several applications such as satellite communication systems, electronics and gas turbine airfoils. These can have shape make traditional finishing processes a challenge additive parts. Therefore, it is desirable that the surfaces be close possible to tolerance of field application. In this study, component was designed manufactured AlSi10Mg alloy through laser powder bed fusion (L-PBF) process. Using...
Purpose Polymer laser powder bed fusion (PBF-LB/P) is an additive manufacturing technology that sustainable due to the possibility of recycling multiple times and allowing fabrication gears without aid support structures subsequent assembly. However, there are constraints in process negatively affect its adoption compared other technologies such as material extrusion produce gears. This study aims demonstrate it possible overcome problems physics accurate mechanism....
Electron beam melting (EBM) made feasible γ-titanium aluminide (TiAl) alloys. However, the surface roughness resulting from EBM is poor, and high mechanical properties make γ-TiAl difficult to be machined. Electro-Chemical Machining (ECM) gaining interest as a finishing process achieve low roughness. Based on anodic dissolution mechanism, ECM realises contactless material removal results particularly suitable for difficult-to-cut materials. The paper investigates use of Ti-48Al-2Nb-2Cr,...
Abstract 3D printers for Rapid Prototyping and Additive Manufacturing have been widely accepted by large small-scale industries or many hobbyists. Due to its nature of layer addition material, identifying defects between the layers can be a crucial strategy determine quality printed product carefully monitoring layerwise process during part building. This kind approach gives an advantage in applications where printing products requires high customization without compromise on quality. In...
Abstract Reducing overall vehicle weight is essential to reduce fuel consumption and pollutant emission improve noise, vibration, harshness (NVH) performances. The substitution with lighter alloys can involve the grand majority of components, depending on market sector. In several applications, e.g., chassis, pulleys, viscodampers, metal sheets are formed in steps, each whom work-hardens material reducing available residual plasticity. Typically, process designed via FEM, whose results...
In recent years, the diffusion of additive manufacturing (AM) or 3D printing (3DP) techniques for polymers have been boosted by expiration earlier patents from last century and development low-cost machines. Since these technologies become more widespread, there is a need to assess capability accuracy machines in terms dimensional geometric tolerance. To this aim, work proposes an innovative reference part benchmarking layerwise processes that involve curing photopolymers. The geometry...
