Abstract
The additive manufacturing has found application in the biomedical sector, mainly in the odontoiatric, neurosurgery, ortophedic and craniomaxillofacial ones, where the number of publications has regularly grown over the last few years [Murtezani et al., 2022]. Five major areas for the biomedical application can be identified: medical models (presurgery training [Saceleanu et sl., 2021]), surgical implants, surgical guides, external aids, bio-manufacturing [Tuomi et al., 2014]. 3D printing presents several advantages with respect to the traditional production approaches: shortened operation time, less blood loss, reduced morbidity of surgical interventions, less infection/inflammation occurrence, higher aestethical results,better correspondence between the custom made implant and the defect contours [Al-Moraissi et al., 2015].
Nowadays, despite many promising results from several in vitro and in vivo studies, the gap between the 3D printing scientific research in the biomedical sector and its translation to the clinical practice is still wide [Di Piazza et al., 2021], also due to the complex regulation aspects and the recent EU Regulation on medical devicesand on invitro diagnostics. Two main challenges in developing the next-generation of AM processes can be cited: the improvement in the speed and resolution of AM processes with lower energy consumption, and the development of new 3D printingmaterials with tunable mechanical, chemical, physical properties.
The main 3D printing drawback consists in the high cost of acquisition. However, currently many efforts have been and are aimed at reducing the overall costs, decreasing prices of both the 3DP hardware and of the used materials.

Abstract
Customization is meant to fit for individuals. Current approaches for customized wearable items, including many biomedical devices, require precise measurement as the first step and then individually produced. 3D printing appears to be just right for the second step.
The shape memory materials (SMMs) are featured by the shape memory effect (SME), so that they are able to achieve one-size-for-all. Indeed, we have seen applications of SMMs in various types of splints for precise fitting of individuals without the first step of measurement. However, most of them are made of polycaprolactone (PCL), which is stiff at room/body temperature, since the purpose of splints is mostly meant for providing strong support. As such, any further movement of that part of our body is restricted.
Recently, we have developed two types of elastic SMMs, one is thermo-set and the other is thermo-plastic. Both can be used for comfort fitting and for 3D printing. Furthermore, the stiffness of them can be tailored.
In this talk, we will introduce these two materials, which may be considered as an elastic version of PCL, so that fitting can be carried out at around body temperature. We will present some typical applications of these materials for comfort fitting in biomedical applications.

Abstract
Direct Digital manufacturing is a family of technologies which enable a product with a digital definition to be fabricated directly without the use of complex tooling and moulds. This enables the mass personalisation of products as the design can be fixed immediately prior to fabrication with clear application in the field of medical devices. However, much of the developments of direct digital manufacturing focuses on simply specifying the shape of the product and this limited scope throws away many of the particular advantages of direct digital manufacturing. This presentation is focused on remedying this situation so that the digital specification of the fabricated product includes properties as well as the form of the product. We use in-situ time-resolving small-angle x-ray scattering measurements performed at the ALBA synchrotron light source in Barcelona to evaluate the control that can be exerted on the morphology of a semi-crystalline polymer during extruder based 3d printing. We use this as a methodology of printing patterns of morphology of the polymer to realise patterns of properties of the polymeric material, specifically the modulus of the polymer. We give examples of test pieces and products produced in this manner which contain spatial variation of the properties and we discuss the resultant properties. We highlight the possibilities of developing this technology to produce practical products

Abstract
The emergence of additive manufacturing with concrete in recent years has lead many researchers, academics, mortar manufacturers, robotics companies, and businesses into advanced research and development with the goal of producing sustainable and profitable solutions. The transition from capability to profitability determines the likelyhood for long term market acceptance and adoption. New technologies and market disruptors face a myriad of obstacles from code compliance, materials testing standards, business profitability planning, sustainability and end of life cycle use, to elevated costs at inception, generational advancements, and the market’s reluctance to change. When assessing first and second mover advantages in a given space, we must first answer one simple question, what problems are we working to solve? How do we develop solutions to improve the likelihood of adoption in the market? And what proven methods are available to us to gauge if we are on the right track? Over the course of the presentation we will discover the path from market research and design, through product development runway creation, to sustainability and profitability. Utilizing industrial design principles for manufacturing, we will develop a working process for the attendees looking into the business side of Additive Manufacturing with Concrete to turn the corner from capability to profitability and beyond.

Abstract
Additively manufactured metallic materials exhibit excellent mechanical strength. However, they often fail prematurely owing to external defects inducing crack initiation. Cracks then propagate through grain boundaries and/or cellular boundaries that may contain brittle second phases. This work investigates the premature failure mechanisms in selective laser melted (SLM) materials. A submicron structure containing semi-coherent precipitates is distributed in a discontinuous but periodic fashion along cell boundaries. Alternatively, martensitic phases are used to create alloys with modulation of phases and different strengthening mechanisms. The observed hierarchical microstructure combining different phases spanning over different length scales, consisting of remelted zones and track core regions at the macro-scale, regions with elongated columnar grains and equiaxed grains at the micro-scale, martensitic laths at the submicron-scale, and a high density of dislocations and stacking faults at the nano- and atomic scale leads to outstanding mechanical properties. The mechanisms determining strength and ductility are discussed in terms of the hierarchical microstructure and internal defects. The cellular structure with a high density of dislocations along their boundaries and the martensitic structure are the reasons for strengthening, while the hierarchical microstructure provides appropriate ductility. Martensitic transformation induced plastic bending of residual FCC plates helps to balance different plastic strains within the heterogeneous structure. This work provides a material design approach for creating hierarchically structured additively manufactured materials with improved strength-ductility tradeoff provided that premature failure is alleviated.

Abstract
Shape memory alloys take place in a class of advanced materials by exhibiting a peculiar property called shape memory effect. These alloys have dual characteristics, thermoelasticity and superelasticity from viewpoint of reversibility, and they are functional materials with these properties. These alloys exhibit these properties in the beta phase field at the phase diagrams, physical mechanical properties change with the variation of temperature. Thermoelasticity is initiated by thermomechanical processes on cooling and deformation and performed thermally on heating and cooling, with which shape of material cycles between original and deformed shapes in bulk level in reversible way. Low temperature phase of these alloys is soft phase, this deformation is plastic deformation, with which strain energy is stored in material and released on heating by recovering the original shape. Superelasticity is performed mechanically by stressing and releasing in elasticity limit at a constant temperature in parent phase field, and shape recovery occurs instantly and simultaneously upon releasing. Parent phase is hard phase, and superelasticity exhibits elastic material behavior. Thermoelasticity is governed by thermal and mechanical reactions, thermal and stress induced martensitic transformations on cooling and stressing, and performed thermally on heating and cooling after first cooling and stressing processes. Superelasticity is governed by stress induced transformation, and ordered parent phase structure turns into the detwinned structures with stressing.
Thermal induced martensite occurs on cooling with the cooperative movements of atoms in <110> -type directions on the {110}-type plane of austenite matrix, along with lattice twinning and ordered parent phase structures turn into twinned martensite structures. The twinned structures turn into detwinned martensitic structures with deformation by means of stres induced transformation. Lattice Twinning is result of lattice invariant shears, with which martensite variants occur in self-accommodating manner and consists of lattice twins. The twinning occurs with internal stresses, while detwinning occurs with the external stresses. Additionally, parent phase has high symmetry, and product martensite phases have low symmetry, and many other parameters also different at these phases.
Copper based alloys exhibit this property in metastable beta-phase region, which has bcc based structures at the parent phase field. Lattice invariant shear twinningis not uniform in these alloys and cause the formation of complex layered structures, depending on the stacking sequences on the close-packed planes of the ordered lattice, like 3R, 9R and 18R depending on the stacking sequences. Periodicity and unit cell is completed through 18 layers in 18R structures.
In the present contribution; x-ray and electron diffraction studies were carried out on two solution treated copper based CuZnAl and CuAlMn alloys. Electron and x-ray diffraction exhibit super lattice reflections. Specimens of these alloys were aged at room temperature, at which both alloys are in martensitic state. A series of x-ray diffractions were taken at different stages of aging in a long-term interval. X-Ray diffraction profiles taken from the aged specimens in martensitic conditions reveal that crystal structures of alloys chance in diffusive manner, and this result refers to the stabilization.
Key words: Shape memory effect, martensitic transformation, thermoelasticity, superelasticity, twinning and detwinning

Abstract
In the present work, the Inconel 718-304L multi-materials were manufactured via laser powder bed fusion. Cracks were observed in the interfacial area between Inconel 718 and 304L stainless steel. The mechanism of the cracks was discussed and the laser scanning parameters were optimized to successfully remove the cracks. Mechanical tests were performed and the results show that the fracture occurs at the 304L side instead of the interfacial area, indicating sufficient strength of the interface. The results demonstrate that multi-materials additive manufacturing has great potential in future application such as automobile and aerospace industry.

Abstract
The promotion of additive manufacturing (AM) as a set of enabling technologies has been a prominent feature to revolutionising the industrial landscape. Due to AM technologies, differences from traditional manufacturing technologies have removed many of the manufacturing restrictions that may previously have compromised a designer’s ability to make the product desirability of consumer products because. Interest in additive manufacturing (AM) continues to grow in many industries aside from requirement of a distinct set of human and capital resources. The high demand for jobs in AM design, engineering and production has overtaken the supply of workers, particularly for engineers with AM experience. In order to meet the challenges of a digital and connected industry (Industry 4.0) where additive manufacturing (AM / 3DP) plays a significant role, the education and training issues identified to enable the effective deployment of AM technologies in the short to long-term. Stating with the AM industry needs to understand what skills are demanded by the industry, and what sort of talent is required to enable the industry growth and accelerate innovation to support businesses in various industries including engineering, manufacturing. On the other hand the digital transformation journey and industrial adoption of AM as a new digital manufacturing for the industry and small and medium-sized enterprises involves making large changes at the organizational level and re-skilling employees, which is generally demand a high to cover the IT and machinery expenses.
In this connection, to overcome the AM workforce skill gaps the concept of ongoing feasibility study project called “AM on the road” will be presented. The aim of the AM mobile concept is to develop and provide the foundation of knowledge and capabilities within the industry sector, such as “R&D know-how, advanced process development, engineering skills, and manufacturing competencies related to AM technology. The versatility of mobile AM on the road relies on the solution to overcome logistic barriers and ensuring continuous printing on demand and quick supply of parts directly at the site of interest. In addition, to the benefits of creating a theoretical, experimental education platform it is promising pathways to conceptualize the challenges faced by groups of small enterprises when adopting new technologies and a decentralized policy effort to systematically increase the use of advanced manufacturing technologies successfully and realize AM technology manufacturing capabilities within industry.

Abstract
Miniaturization techniques have received remarkable interest over the past few decades as they allow for minimal material consumption, superior control over operational conditions, and the possibility to fine-tune the properties of the materials. Among those, microfluidics technologies have emerged as an appealingclass paving the way for the miniaturization of fluidic processesfor various applications. On the other hand, recent advances in the fabrication of advanced materials have expanded the application of these materials in various fields of science and technology such as biomedical engineering, biochemistry, healthcare, nanotechnology, and sensors. Despite the extensive progress in the synthesis of advanced materials, the majority of studies investigate their fabrication processunder equilibrium conditions, where only the thermodynamically stable species can be obtained. This limitation not only is a drawback for the proper understanding of the process but also hampers the effective fabrication of materials with a desired structure and functionality. To tackle this limitation, microfluidic technologies have been shown to be capable of pushing the system toward out-of-equilibrium conditions, which broaden the scope of the advanced materials that can be achieved, which are unattainable using existing conventional methods. Although most of the microfluidic approaches employ polymeric chips, devices made via 3D printing or additive manufacturing have been also shown effective for microfluidic experimentations. These devices benefitfrom higher resistance against organic solvents, may be fabricated rapidly and reproducibly using 3D printing techniques, and their design can be adjusted easilyby simply modifying their drawn design using drawing software.

Abstract
3D printing/ Additive manufacturing is considered the next industrial revolution. In order to disrupt the traditional manufacturing processes of metal parts, 3D printing (3DP) has to solve two major problems; 1. Reduce the parts manufacturing time by optimizing the processes. 2. Reduce the waste of materials by developing metal alloys. Post-processing of these parts and materials is an important aspect that will ultimately boost 3DP applicability in industries such as Automobile, Aerospace, Medical, etc.
There is a need for compact, precise and fast processing heat treatment furnaces for post processing. In order to solve this need, we have developed NORMANBELL furnaces in the Chinese market and NORMANTHERM furnaces for the global market of metal 3DP. The main factors to be considered for the selection of best-fit furnaces are; work materials, print bed size, the precision required, strength, and application of the parts. From this presentation, audiences can learn about the need for metal 3D printing heat treatment, different types of furnaces, and their selection process.

Abstract
Carbon is one of the basic elements of our planet, and all living species contain carbon, but its pure forms also show unique properties. All-carbon composites are carbon materials reinforced with other carbon materials, typically nanostructures such as carbon nanofibers or nanotubes, and there are many all-carbon materials with useful and unique properties. In particular, hybrids with three-dimensional (3D) structure obtained by a green hydrothermal process are preferred more than those with basic 2D structure due to the large specific surface area offered and the rapid access of electrolyte ions in the unique 3D graphene network.
In this talk, I will talk about the importance and current development of 3D all-carbon hybrids for high-performance photonic and optoelectronic devices. In a comprehensive way, I will talk about the advantages and disadvantages of 3D all-carbon hybrids for photonic and optoelectronic applications.

Abstract
In stereolithographic additive manufacturing (STL-AM), 2-D cross sections were created through photo polymerization by UV laser drawing on spread resin paste including nanoparticles, and 3-D models were sterically printed by layer lamination. The lithography system has been developed to obtain bulky ceramic components with functional geometries. An automatic collimeter was newly equipped with the laser scanner to adjust the beam diameter. Fine or coarse beams could realize high resolution or wide area drawings, respectively. As the row material of the 3-D printing, nanometer sized metal and ceramic particles were dispersed into acrylic liquid resins at about 60 % in volume fraction. These materials were mixed and deformed to obtain thixotropic slurry. The resin paste was spread on a glass substrate with 50 μm in layer thickness by a mechanically moved knife edge. An ultraviolet laser beam of 355 nm in wavelength was adjusted to 50 μm in variable diameter and scanned on the spread resin surface. Irradiation power was automatically changed for an adequate solidification depth for layer bonding. The composite precursors including nanoparticles were dewaxed and sintered in the air atmosphere. In recent investigations, ultraviolet laser lithographic additive manufacturing (UVL-AM) was newly developed as a direct forming process of fine metal or ceramic components. As an additive manufacturing technique, 2-D cross sections were created through dewaxing and sintering by UV laser drawing, and 3-D components were sterically printed by layer laminations with interlayer joining. Through computer-aided smart manufacturing, design, and evaluation (Smart MADE), practical material components were fabricated to modulate energy and material transfers in potential fields between human societies and natural environments as active contributions to Sustainable Development Goals (SDGs).
