🗝️ It's no secret, that materials are the key to unlocking the full potential of #3Dprinting. However getting the right material can be challenging. That why we are working closley with renowned institutes such as Fraunhofer IPAto generate knowledge and parameters for #3Dprinting of Polymers. Our HSS Material Network accelerates the development of new 3D printable materials and tailors them to you specific needs. 💡Find more infos and examples here: https://lnkd.in/diPQRWiN

We have developed a new #Biomaterial for #4DPrinting based on alginate, poloxamer, and #Flax Fibres. This Biomaterial can be used in #Bioprinting applications; the addition of only 1 wt% of Flax Fibres increases the tensile stiffness and strength by factors of 2.5 to 3. The inclusion of the Flax Fibres also increased the viscosity by up to 129% at higher strain rates. #Hygromorphism is also present, with a five-fold increase in the moisture expansion between the printing and transverse directions. Moreover, the use of Flax Fibres stabilizes the actuation authority of #Morphing Structures made with this material when variations in the surrounding relative humidity occur. You can read the paper at the following #openaccess link: https://lnkd.in/dxb8an7p. The work has been led by Charles de Kergariou from the Bristol Composites Institute, together with myself, Graham J. Day, James Armstrong and Adam Perriman from the University of Bristol, The Australian National University and the University of Glasgow.

Change of structure of #3DPrinted tissues open up a whole new avenue to optimize tissue regeneration. Chemically activated change might be incredibly useful as well in case of work with structural change in vivo. #4DPrinting migh be the next step in seemless, implantable bioprinted structures.

The research focuses on developing photocurable liquid formulations using renewable resources like terpenes and itaconic acid, aiming to replace petroleum-based materials. A biobased resin, perillyl itaconate (PerIt), was synthesized from renewable sources and used to create networks with adjustable properties through photoirradiation. By adding nonmodified terpenes as reactive diluents, a wide range of photocured networks was produced with varying mechanical properties. The resins showed rapid curing kinetics, could form brittle or elastic materials, and displayed good thermal resistance. Selected formulations, particularly those containing PerIt and limonene, were suitable for additive manufacturing, allowing for high-resolution object printing using digital light processing (DLP). Overall, this method offers a straightforward approach to prepare renewable resins for rapid prototyping applications.

Discovery challenges 30-year-old dogma in associative polymers research The discovery, which has been published in the journal Physical Review Letters, was enabled by new associative polymers developed in Cai's lab at the UVA School of Engineering and Applied Science by his postdoctoral researcher Shifeng Nian and Ph.D. student Myoeum Kim. The breakthrough evolved from a theory Cai had co-developed before arriving at UVA in 2018.

Determining whether the water you drink has micro- and nanoparticles isn’t that hard. I describe methods in my monthly Design World column using only common items to tell whether that carton of water actually has less particles in it than the water in a PET bottle. Particles, if you see them, are likely plastic. The method can’t tell the difference between plastic, inorganic or biological particles. That requires more specialized equipment. It is a shortcoming, but if there aren’t particles, there can’t be plastic particles. Check out the column and the video showing particles in sealed bottled water. https://lnkd.in/gBpB7qUU https://lnkd.in/g9MmN9Kz

Look beyond! Using bio-based residual and waste materials instead of petroleum-based resources in additive manufacturing can be a real game changer in times of climate change.   Mushroom mycelium is a promising material in this regard. It has excellent mechanical properties when dried and can be used together with other residual materials, e. g. lignin. Within this process, the residual materials are linked via biological catalysts (enzymes).   With the help of our print heads for fluids and pastes these materials become usable in additive manufacturing.   The results: ●  Promotion of a circular economy ●  Reduction of waste ●  Complete biodegradability of materials ●  Energy and chemical savings ●  Decentralized production on site For more information visit our website: https://lnkd.in/eTcWSVuC   Be sure to also visit the exhibition RETHINK:DESIGN with its main subject “Climate Relevance” and learn more about this exciting topic: https://lnkd.in/ejBQcKHP   #ViscoTec #AdditiveManufacturing #3DPrinting #MushroomMycelium #ClimateChange #ClimateRelevance #RethinkDesign #Printhead #Volumetric #Precision #Reliability #Efficiency

University of Maine researches to make stronger cellulose nanofibrils with less energy. UMaine ASCC and School of Forest Resources researchers SUNGJUN HWANG, Yousoo Han, and Douglas Gardner, in collaboration with UMaine Process Development Center researchers Colleen Walker and Donna Johnson, article titled “Spray Drying Enzyme-Treated Cellulose Nanofibrils” has been published in Polymers. This shares the results of using a lab-scale mass colloider to produce enzyme-treated cellulose nanofibrils (CNFs). This is highly important because CNFs can be used to strengthen materials like plastics and in additive manufacturing (3D Printing) feedstocks as an alternative to some petroleum-based materials.
