“…Through melt-blending, the authors were able to produce prints with comparable performance to those using higher cost polyurethane filaments. Although the majority of other studies are concerned with non-pharmaceutical polymers [ 55 , 56 , 57 ], some researchers are examining melt-blends in FFF for medical applications. Kosorn et al [ 58 ] produced blends containing different compositions of polycaprolactone (PCL) and poly(3-hydroxybutyrate- co -3-hydroxyvalerate) (PHBHV) for porous scaffolds.…”

Material Considerations for Fused-Filament Fabrication of Solid Dosage Forms

et al. 2018

Material choice is a fundamental consideration when it comes to designing a solid dosage form. The matrix material will ultimately determine the rate of drug release since the physical properties (solubility, viscosity, and more) of the material control both fluid ingress and disintegration of the dosage form. The bulk properties (powder flow, concentration, and more) of the material should also be considered since these properties will influence the ability of the material to be successfully manufactured. Furthermore, there is a limited number of approved materials for the production of solid dosage forms. The present study details the complications that can arise when adopting pharmaceutical grade polymers for fused-filament fabrication in the production of oral tablets. The paper also presents ways to overcome each issue. Fused-filament fabrication is a hot-melt extrusion-based 3D printing process. The paper describes the problems encountered in fused-filament fabrication with Kollidon® VA64, which is a material that has previously been utilized in direct compression and hot-melt extrusion processes. Formulation and melt-blending strategies were employed to increase the printability of the material. The paper defines for the first time the essential parameter profile required for successful 3D printing and lists several pre-screening tools that should be employed to guide future material formulation for the fused-filament fabrication of solid dosage forms.

“…[247] PLA is another material commonly used in FDM. [246] It is a biodegradable semicrystalline thermoplastic derived from renewable resources, and is easier to process than ABS because of its lower coefficient of thermal expansion and lower printing temperature required. Furthermore, printed PLA specimens exhibit higher tensile strength and better finishing than ABS specimens.…”

“…It is an amorphous terpolymer consisting of polybutadiene and styrene‐acrylonitrile copolymer phases, of which the polybutadiene phase imparts toughness, while the styrene‐acrylonitrile phase enhances its modulus and tensile strength without affecting its dimensional accuracy. [ 246 ] ASA can serve as an alternative to ABS, being similar to it except that acrylate rubber is used instead of polybutadiene. ASA is more weather‐resistant than ABS and is thus more suitable for outdoor applications.…”

“…Polymer blends can achieve higher mechanical properties than amorphous polymers, exhibit enhanced surface finish and mechanical isotropy, and even impart functional capabilities such as shape memory or bioactivity. [ 246,256 ] PC/ABS and PC/PEI (Ultem 9085) that were originally developed for injection molding applications are currently the most popular blends for FDM. PC/ABS is one of the most widely used thermoplastics in the traditional plastics industry and has recently been processed using FDM; its printed parts demonstrate high strength, toughness, and heat resistance.…”

Additive manufacturing (AM) is the process of printing 3D objects in a layer-by-layer manner. Polymers and their composites are some of the most widely used materials in modern industries and are of great interest in the field of AM due to their vast potential for various applications, especially in the medical, aerospace, and automotive industries. Many studies have been conducted to develop new polymer materials for AM techniques, which include vat photopolymerization, material jetting, powder bed fusion, material extrusion, binder jetting, and sheet lamination. Although several reviews on the development of polymer materials for AM have been published, most of them only focus on a specific application, process, or type of material. Therefore, this article serves to provide a comprehensive review on the progress in polymer material development for AM techniques. It begins with an introduction to different AM techniques, followed by highlighting the progress of their development. Material requirements, notable advances in newly developed materials and their potential applications are discussed in detail and summarized. This review concludes by identifying the major challenges currently encountered in using AM for polymer materials and providing insights into the valuable opportunities it presents, in hopes of spurring further development in this field.

“…SAN content had little effects on glass transition temperature, but mass flow index and elongation at break can decrease while the tensile strength and modulus of ABS/SAN blends can be improved. For printed samples with the longitudinal and transverse direction of the print, the SAN content improved mechanical properties without the drop of the dimensional stability [Zhu 2017]. Many other studies have been investigated about blending of SAN together with ABS or other copolymers.…”

Acrylonitrile butadiene styrene (ABS) is a tough material, which is used for engineering purposes (e.g. covers of electronic and engine parts). On the other hand, styrene acrylonitrile (SAN) is a brittle transparent material with good optical properties, it is used for household items, such as bowls and boxes in refrigerator. Both of these materials can be loaded by impact forces, for example fall of the item on the floor. In this study the influence of fall height on ABS and SAN samples under drop-weight impact test is tested. After the test, failures are evaluated as well as maximum impact force and all consumed work, which was used for the deformation and the failure of the material.
