Additively manufactured paper products from cellulose-pulped fibers and its quality according to rheology and 3D printing performance

Additive manufacturing is currently the accepted approach to produce innovative and complex designs. This research achieves what the designer's engineering envisions by using interesting materials such as cellulose-pulped fibres to formulate 3D paper printed objects. This experimental study introduces optimizing these 3D printed objects, and considering their quality and the structural integration; starting from the mixture design to manufacturing performance. Then, these objects would be used as functional products for serving facade envelopes. Therefore, such applications need ensured products that are been developed and tested to be standing up to the product's requirements and quality; this is what would this research introduce. Several aspects are investigated: such as the selectivity of the materials, design formulation, and mixture strengthening. The process parameters have also been studied: finding a balance between the printing speed, flow rate, and air pressure for better quality and structural integration for each nozzle (1.6 mm, 1.2 mm, and 0.6 mm). Each mixture is evaluated according to printability, buildability, rheology behavior, extrusion quality, and shrinkage outcomes. The results illustrate that there is an optimal mixture for each nozzle with experimentally specified configurations.
