“…However, the range of commercially available materials that are flawlessly processable by means of FFF is still small . Although plenty of composites have been investigated, the base materials are still limited to a handful of polymer types. In particular, the FFF market lacks polymers for demanding technical applications.…”

A challenge in extrusion‐based additive manufacturing of polypropylene (PP) filled with spherical particles is the combination of decent processability, excellent warpage control, and the retention of the tensile strength of neat PP. This study addresses this issue by adopting two approaches. Firstly, different size fractions of borosilicate glass spheres incorporated into PP are compared. Secondly, the temperature of the printing chamber (TCh) is varied. The effects of these features on the thermal, crystalline, morphological, tensile, impact, and warpage properties of 3D‐printed parts are examined. Smaller glass spheres (<12 µm) are found to be superior to larger fractions in all investigated aspects. Notably, the corresponding composites show higher tensile strengths than neat PP. An increase in TCh results in a more homogeneous temperature distribution within the printing chamber and promotes annealing during printing. Consequently, the dimensional accuracy of printed parts is improved. Additionally, β‐crystals and larger spherulites are formed at a higher TCh.

“…Spoerk et al found that 80–90% of the tensile strength of compression molded PLA could be achieved by optimizing the printing parameters of PLA. FDM was originally targeting prototyping applications; now a shift is seen to end‐use parts for which higher requirements are set, raising the need for more fundamental research on new materials and new techniques . In this context, filaments were reinforced with metallic, ceramic, and fibrous fillers.…”

Production and characterization of bamboo and flax fiber reinforced polylactic acid filaments for fused deposition modeling (FDM)

A new type of fiber reinforced filament materials for Fused Deposition Modeling applications has been developed. Polylactic acid (PLA), compounded with two types of plasticizer, is reinforced with bamboo and flax fibers. The fiber fractions are characterized by measuring their length (l) over diameter (d) before and after compounding so that the effect of the l/d on the final filament properties can be systematically studied. The pre‐processing and processing activities, to produce filaments with a diameter of 3 mm, are described. The porosities and the orientation of the fibers in the filament are assessed to predict the theoretical stiffness of the filament via short fiber mechanics which is compared to the experimental results. Reinforcing the PLA filament with short bamboo fibers (l/d = 4–5) increases the modulus with 91–230%, whereas the dust‐like fractions only show an increase up till 39%. The glass transition temperature of the produced filaments is also determined to investigate the suitability of the filaments and finally a demonstrator part was printed. POLYM.

“…A commonly used synthetic polymer in extrusion‐based printing is polycaprolactone (PCL). Its biocompatibility, biodegradability, and ease of processing make it suitable for tissue engineering applications and have been widely used by itself or as the matrix for composites . Although PCL scaffolds with hierarchical and anisotropic features have been developed, typically focusing on architectural features or composites to achieve this, the crystal structure of the polymer, such as crystal orientation, spherulite size, and crystal volume, is rarely reported.…”

3D printing techniques are utilized to produce biomaterial scaffolds with porous architectures that enable cell attachment, biological factors, and appropriate mechanical strength. As the basic building block of a scaffold, the individual filaments should have sufficient mechanical properties, comprising high compressive loading, and fracture resistance to mimic the natural tissue organisation. In this contribution, process–structure–property relationships in melt extruded polycaprolactone filaments are investigated by considering crystalline features, tensile properties, and an array of processing parameters. The tensile properties of the filaments are improved significantly with relatively higher screw rotational speed and relatively lower processing temperature resulting in considerable increase in Young's modulus. The favorable properties are attributed to the increased crystal volume fraction and anisotropy. Thus, this study provides initial pathways for the potential control of mechanical properties of bioscaffolds via engineering crystalline structural features in printed filaments.
