Abstract null null Projection micro-stereolithography (PμSL) is an effective technique to rapidly fabricate porous scaffolds with complex structures of photo-crosslinkable polymer resins, which normally contain a reactive diluent and a photo-initiator. In previous reports on 3D printing of poly(propylene fumarate) (PPF) scaffolds, diethyl fumarate (DEF) was unavoidably used as a reactive diluent in the PPF resin. Here we present a photo-crosslinkable resin composed of PPF and hyperbranched polye...

Abstract null null Electrical conductors are usually made of pure copper because this material shows outstanding electrical conductivity (IACS > 100%). Additive manufacturing can be used to further improve the performances of such electrical conductors because it enables to consider sophisticated geometries impossible to be fabricated by conventional processing routes such as casting, machining or hot forming. In the present work, Electron Beam Powder Bed Fusion is optimized to achieve dense pur...

Abstract null null Uniform morphology and good metallurgical bonding between neighboring droplets are crucial in metal droplet-based 3D printing. However, this technique is usually accompanied by a heat accumulation effect during the printing process, leading to poor forming accuracy and non-uniform microstructure and properties of the formed parts. Since the heat accumulation effect is an intrinsic physical property in metal droplet-based 3D printing technique under fixed-parameter conditions, ...

Abstarct null null The state of the art in the thermal joining of aluminum and titanium sheets in butt or overlap joint configuration specifies that the titanium should remain in the solid state to limit the formation of a brittle intermetallic compound layer in the interface. In this study, aluminum samples were additively manufactured onto titanium substrates and vice versa titanium samples onto aluminum substrates using a standard commercial laser powder bed fusion machine. The influences of ...

Abstract null null To elucidate the possibility of controlling the microstructure and mechanical properties of Al–Si alloys additive-manufactured by laser powder bed fusion (L–PBF), the relationship among the laser conditions, microstructural characteristics (crystal grain, cellular microstructure, and solute Si in α–Al matrix), and tensile properties of L–PBF manufactured AlSi12 alloy samples was investigated. The crystal grain size and fraction of null null oriented α–Al crystal grains toward ...

Abstract null null The post-processing on the additively manufactured component is of huge interest as the key to tailor the microstructure to obtain certain mechanical properties. In this present study, the effects of hot isostatic pressing, as well as heat treatment on the microstructure, phase configuration and mechanical properties of laser powder bed fused (LPBF) IN718 superalloy were systematically investigated. Three different post-processes were studied such as hot isostatic pressing (HI...

Abstract null null Additive manufacturing (AM) is a fabrication technique that digitally deposits materials in layers to form a desired 3D structure or shape. It is not as wasteful in materials compared to digital subtractive manufacturing (SM). In 3D printing, complex and unique metallic structures, more energy intensive and expensive techniques such as selective laser melting (SLM) or electron beam melting (EBM) are often used. As metals are an important class of materials used in AM, there is...

Abstract null null Tensile testing is often proposed as the preferred methodology to qualify builds and materials produced through additive manufacturing. While there is already work demonstrating the difference in measured properties between tensile specimens produced in different build orientations, this does not extend to different specimen geometries. In addition, the body of knowledge in this domain is typically made up of studies that utilize custom combinations of specimen geometries, par...

Abstract null null Polymer metallization via cold spray additive manufacturing is an emerging thermal spray approach for deposition of thick metallic coatings on polymers and fiber-reinforced composites that promises high productivity, ecofriendliness, and scalability of the coating process. In polymer metallization via cold spray, solid metallic powder is accelerated by a supersonic stream of preheated gas and propelled toward a polymer substrate, where it is built layer-by-layer via impact-ind...
