  • Additive Fertigung mit nachwachsenden Rohstoffen – Binder Jetting mit Pulver aus Pfirsichschalen [Elektronski vir] = Additive manufacturing of bio-based materials - binder jetting of peach kernel powder
    Kühnel, Lisa ...
    Innovative bio-based materials and new manufacturing technologies can make a substantial contribution to conserving resources. Such a path can be taken by adapting Additive Manufacturing processes ... for the use of renewable/residual materials. For those materials, we decided to develop an upcycling strategy while at the same time making use of their individual properties. This article describes the printing by Binder Jetting (3D Printing, 3DP) of comminuted peach kernels with several water-soluble binders, such as polyvinyl alcohol (PVA), sugar, flour and lignosulfonate. After material processing (pre-comminution, separation of the seeds and milling), the printable powder is analysed and mixed with the binder. Parts manufactured from such materials have a high decomposition rate measured in hours when exposed to water, making them ideal for applications such as unique single use packaging or short-lifetime products. To obtain stable parts, different peach/binder concentrations were investigated. Densities, decomposition rate and strength of test specimens were measured. Thus, acceptable printing results were achieved by systematically adjusting the parameters. To further increase the strength of the printed bodies, suitable coatings will be investigated in the future.
