Title: 5D printing of nano-laden fibre aerogel

Biography:

Ph.D. Ruben Foresti Postdoctoral Researcher in applied medical technical sciences at University of Parma. Research field addressed in 3D, 4D and 5D processes for digital fabrication of biomedical devices and customized scaffolds. PhD in Industrial Engineering at University of Parma. Design and implementation of additive manufacturing systems for biomedical and food applications, including software and 3D model design. Expertise in rapid prototyping of automated systems with remote control including the design and the software development, electrical parts and mobile application.

Abstract:

The organs functionality and the related material mimicry properties (Kokkinis) are difficult to reproduce. The smart design and reconstruction processes (Avventuroso; Wu) requires the material functionalization and engineering. To overcame these problems, we merged the composite biomaterials (Guarino; Milazzo) properties with the bio-composite manufacturing processes (Foresti). In fact, the composite biomaterial can modulate its properties with nanoparticles and the resulted bio-ink can be used for the fabrication of the fibre, the adhesive interface and the coating matrix of a bio-composite material. For example, with a flexible fibre covered with an adhesive coating (impermeable and unable to improve the cells adherence, avoiding occlusion problems) it is possible to develop a functional vessel (Hajal).
We reconstructed a femoral peripheral artery bifurcation utilising a patient morphology CT, obtaining a full customisable 5D printed object (Gillaspie). The resulted digital model was used to realise, with a custom made RFP bioprinter (Ozbolat), a sodium alginate-based (enriched with green fluorescent NPs) coating balloon gelled with EtOH, dehydrated (nano-laden fibre aerogel) and tested in-vitro. Furthermore, in-vivo tests (Fig. 1) with the bio-composite device demonstrated the uniform gradual release and a very short dissolution time (~ 2/3 minutes).
Thus, digitalising the object we can realise 5D printed devices with hard and/or soft material (engineering parameters, functional activity and biological interaction). Moreover, using different bio-composite material, merged with the patient morphology, it is possible to implement a synthetic organ for preliminary tests and training.

University of Auckland, Newzealand

Title: Design for AM – the key to the industrialization of additive manufacturing

Biography:

Professor Olaf Diegel is an educator and a practitioner of additive manufacturing and product development with an excellent track record of developing innovative solutions to engineering problems. In his role as professor of additive manufacturing, in the faculty of engineering at the University of Auckland, in New Zealand, he is heavily involved in all aspects of additive manufacturing (AM). He is also one of the principal authors of the annual Wohlers Report, considered by many to be the bible of AM. His current main area of research expertise is in design for AM. In his consulting practice he develops a wide range of products for companies around the world. Over the past three decades he has developed over 100 commercialized new products including innovative new theatre lighting products, security and marine products and several home health monitoring products and, for this work, has received numerous product development awards.

 

Abstract:

Many industries approach additive manufacturing (AM) as a drop-in replacement for conventional manufacturing technologies. This approach, however, does not fully utilize the unique possibilities that additive processes offer. For over thirty years, AM has been extensively used as a rapid prototyping technology. When using the technologies for manufacturing, however, it should be noted that AM does not remove all manufacturing restrictions. It, instead, replaces them with a different set of design considerations that designers must take into account if they wish to successfully use the technologies to add value to their products. Otherwise AM can easily become a slow and uneconomical way of manufacturing products or parts.

 

It is also of great importance to understand that, despite much of the marketing hype over the past few decades, AM is not an “easy” technology that can make absolutely anything. It requires a good understanding of the different technologies and how to design for them. In fact, printing parts in metal, for example, can be downright hard, and the use of AM to manufacture metal parts should only be considered if the process truly adds value to the product.

 

This talk attempts to impart some practical guidance on the thought process required to design parts that gain the maximum benefit from what AM can offer.

Abstract:

Commercial and military aircraft such as the V-22 Osprey are being constructed using substantial amounts of advanced light-weight composite materials. Impact damage as well as fatigue stress can cause internal delaminations leading to catastrophic part failure without prior visible warning. A reliable health monitor system can enable condition-based maintenance. This can significantly reduce life cycle costs by minimizing inspection time and effort, and by extending the useful life of new and aging aerospace structural components. In this paper we describe a smart structures approach for the detection and assessment of damage in critical composite structures. An array of piezoelectric transducers is attached to the structure for both actuation and sensing. The system actively interrogates the structure with wideband chirp excitation of multiple actuators. Statistical analysis of the changes in the vibration response is used to detect, localize, and assess the severity of damage in the structure. Damage is indicated when the vibration signatures differ from a known baseline condition. Pattern recognition techniques are employed to distinguish damage responses from those due to benign changes such as temperature or loading variations. This model-independent damage detection approach can be applied without extensive algorithm training. Tests were conducted in the fatigue test facility at Bell Helicopter on the V-22 pendulum yoke. Results presented here demonstrate that vibration signature analysis is a viable technique for in-situ damage detection of advanced composite aircraft components

Abstract:

Additive manufacturing can greatly increase a manufacturers efficiency. When using expensive materials like titanium, manufacturers that use 3D printing can save big. Being able to build the component from the bottom up gives manufacturers the unique ability to only use the amount of material that is absolutely necessary. Furthermore, manufacturers can create complex and lightweight components that were not possible with subtractive manufacturing. Having the ability to create complex parts lets manufacturers build a product that would usually consist of multiple parts and turn it into one solid product. Not only can this improve the overall strength of the product, but it requires less time and energy than manufacturing the separate components and then fastening them together. Also, aerospace manufacturers have found that they can produce hollow structures that were not possible with traditional manufacturing techniques. 3D printing uses less material as well as reducing the weight of the overall product. Less weight on an aircraft means less fuel consumed.

Abstract:

On-demand and distributed manufacturing of spare parts is considered in the Additive Manufacturing industry as one of the largest potential industrial application. Spare parts are critical for equipment repairs, however with the traditional centralized production model, it is impossible to always have the right spares, at the right place, at the right time. This is especially true for long tails or old spare parts, for which keeping inventory doesn’t make sense due to too low demands and prolonged stay in inventory. Additionally, supplying this parts from the OEM or distributors happen to be costly and to take long lead time. On that postulate, the advantage of AM is clear, but to make it actually happen? Which parts can be produced by Additive Manufacturing? How to build the business cases? How to scale-up a “transfer to AM” process over hundred thousand of spares? Won’t the engineering investment to transfer an SKU to AM kill the business case considering the high-mix/low volumes characteristics of long tails? All that questions will be addressed by Paul Guillaumot, CEO of Spare Parts 3D, company specialized in providing solutions to the aftermarket sector for producing on-demand and locally spare parts thanks to the use of AM.

Title: Biomimetic 3D bioprinting of cellular laden nanocomposite scaffold through co-axial and core-co-cultured structure

Biography:

Fahimeh shahabipour is a PhD student in Medical Biotechnology at Pasteur Institute of Iran, Tehran. She spent 8 months In MIT-Harvard division as a research scholar in 3D bioprinting and 3 months at Radboud University in the Netherlands to conduct a project. Her research focused on the application of 3D bioprinting in the fabrication of 3D biomimetic bone graft.

 

Abstract:

There is a need to recapitulate the native complexity of bone structure within engineered 3D structures with tailored biological and mechanical properties. In this study, we suggest an innovative cell-printing process, supplemented with core/shell nozzle and co-cultured/mono-cultured methods, to achieve 3D osteon-like structures through cell-laden bioinks using an extrusion-based 3D bioprinter in one-step. In this study, vascularization promoting and osteogenic bioinks were developed based on different concentration of GelMA-alginate hydrogels with the incorporation of hydroxyapatite nanoparticles. These hydrogels were chosen due to their suitable mechanical stability, swelling ratio, and printability. To obtain a core/shell osteon-like structure (CSBP), we used a vascularization bioink combined HUVECs in the core region, and used osteogenic- MC3T3-E1 cells-laden bioinks in the shell region. Pure gelatin was concentration in all bioinks to support both of core and shell structures during 3D bioprinting. Core-co-cultured osteon-like structure (CCBP) was fabricated through co-culturing of HUVECs and MC3T3 cells within bioink in the core region. Mono-cultured printed structure composed of single cell lines served as a control. The fabricated 3D-core-cocultured of HUVECs-MC3T3 cells showed significantly higher cell viability (84%) compared to that (78%) of a 3D-core/shell of HUVECs/MC3T3 cells. Both fabricated structures exhibited outstanding cell viability in comparison with (65%) of mono-cultured 3D cell-laden scaffold (control). In addition, significant increases in osteogenic properties were observed in the co-culture samples versus the mono-culture controls. We demonstrated that both co-culture configurations were able to promote mineral deposition in the absence of exogenous osteogenic factors. Although the CSBP configuration displayed less viability than CCBP, this structure still exhibited good osteogenic and angiogenic properties. In conclusion, this investigation provided highlighted the potential of both structures as biomimetic bone scaffolds for complex bone tissue and other tissue engineering application.

Abstract:

The article introduces the additive manufacturing of components made of high-performance ceramics, especially of silicon carbide, silicon nitride, aluminium oxide and zirconium oxide. The entire process chain from material composition over filament manufacturing, 3D-print and further processing to the ready to use ceramics component was subject of the investigations. The work focussed on the development and processing of ceramics filaments. They can be processed on different 3D-print systems. This development was tested on an extruder system with an installation space volume of 200x200x250 mm3. The feedstock has to be suitable to be turned into a printable filament by means of a 1-screw extruder for which a sufficient flexibility for winding and a minimal tensile strength are necessary. The flexibility was characterised by a minimal bending radius at which the filament does not break yet. The material development included the harmonisation of the organic components in terms of composition and amount of the ceramic powder. Filaments with diameters of 1.75 and 2.85 mm were provided. A steady material discharge is necessary in order to process the two very different source materials (ceramics and plastic) by means of the FDM-procedure. This requires the homogeneous heating of the filament. The homogeneity directly affects the achievable component quality. Result is a material-adjusted viscosity-temperature controlled process for the processing of the ceramic filaments. First applications which were investigated and successfully realised with the new process chain are shown.
