Abstract As additive manufacturing technologies advance, new opportunities are opening up for their application in the furniture industry. Wood remains one of the leading raw materials in the furniture industry; therefore, possible options for combining it with 3D printing have been researched. The bonding of 3D-printed polymer parts with wood or 3D printing with wood-plastic composites is already known, but in our research we attempted to directly 3D print polylactic acid (PLA) on wood surfaces. The effect of printing parameters, as well as the surface preparation of wood on the shear strength of the bond between… More >

Abstract The effects of selected printing parameters on the fire properties of additively produced composites from neat polylactic acid (PLA) and wood/PLA filaments were investigated. The reaction to fire of the 3D-printed specimens was tested according to the ISO 5660-1 cone calorimeter test method. The results showed that the properties of the specimens when exposed to fire were significantly affected by the incorporation of wood flour into the PLA filament. It was also interesting that PLA specimens had much better reactions to fire than the wood/PLA specimens. Time to ignition was found to be much longer More >

Abstract Acellular dermal matrix (ADM) as a biomaterial is currently believed to be promising tissue repair improvement. With the development of tissue engineering, ADM is increasingly used as biological scaffolds. We explored the feasibility and performance of ADM biological scaffolds that fabricated by 3D printing. This paper presented our study on the printability of 3D printed ADM scaffolds, with a focus on identifying the influence of printing parameters/conditions on printability. To characterize the printability, we examined the fiber morphology, pore size, strand diameter, and mechanical property of the printed scaffolds. Our results revealed that the printability… More >
