“…Apart from material alterations, for example, by decreasing the degree of crystallinity by incorporating ethylene monomer segments to PP or by blending PP with other thermoplastics, changes in the processing can significantly improve the warpage behavior of 3D‐printed PP components. Hämäläinen, for example, found that the degree of warpage of 3D‐printed PP is highly dependent on the geometry of the component that is processed.…”

“…Within the last years, a myriad of studies on the incorporation of various fillers into thermoplastics for extrusion‐based AM have been conducted . Various fillers, such as cellulose nanofibrils, thermotropic liquid crystalline fibrils, bamboo fibers, hemp and harakeke fibers, short glass fibers, ash, and mineral fibers have been incorporated into 3D‐printed PP to improve the material's mechanical, rheological, or thermal properties. However, only a handful of studies have focused on the warpage prevention by incorporating fillers into PP filaments.…”

“…A brim was essential for printing, which is commonly used for semicrystalline, warpage-prone polymers, such as in the FDM of polypropylene. 48 This increased the surface area of the initial layer and allowed for better adhesion of the samples to the bed. Another essential print setting was the cooling fan rate to be set to 5%.…”

“…The studies [ 19 , 31 , 32 , 33 , 43 , 45 , 46 , 48 , 53 , 57 , 58 , 60 , 61 ] were missing either one or both of information (fiber wt% or maximum tensile strength) and these studies [ 56 , 59 , 65 , 67 , 73 ] did not include tensile strength as a part of their evaluation.…”
