“…Thermoplastic polyurethane (TPU, red Fiber ex 40D, Fiberology) lament exhibits highly elastic, rubber-like properties, leading to a range of applications such as prosthetics and orthotics, sporting equipment, plumbing, and medical equipment (SENNA 2019; SĂRĂNDAN 2022; Desai, Sonawane, and More 2023). Acrylonitrile butadiene styrene (ABS, generic lament) is a resilient thermoplastic polymer, ubiquitous in conventional and advanced manufacturing of computer monitors, Lego® bricks, keyboard caps, and home appliances (Anandhan et al 2003;Sabatini et al 2023;Gurjar, Sharma, and Sarkar 2018). The nal lament material is a composite of chopped carbon ber and nylon matrix (CFN, black CF-NYLON G3, CARBONX), exhibiting desirable physical and mechanical properties suitable for industrial applications (Alari 2022).…”

The recent availability of a wide range of additively manufactured materials has facilitated the translation from prototype-limited to application-ready 3D printed components. As such, additively manufactured materials deployed in dynamic environments require extensive characterization to elucidate and optimize performance. This research evaluates the dynamic response of fused filament fabrication and vat-photopolymerization printed polymers as a function of temperature. Dynamic mechanical analysis is used to extract the viscoelastic properties of several generations of samples exhibiting a range of thermomechanical behavior, highlighting the stiffness and damping characteristics. A modified stiffness-temperature model supports the experimental characterization and provides additional insight concerning the molecular motion occurring over each thermal transition. The insights from the analysis were collated into a case study that leverages their dynamic characteristics in a multi-material application. The outcomes from this research assimilate a framework that defines the temperature operating range and broadens the design envelope for these additive manufacturing materials.

“…The tensile strength and elongation behavior of the polymeric materials showed a decrease and this may be associated with increased screw rotation speed. Higher screw revolutions in the extrusion process caused an increase in the degree of molecular orientation and degradation of the butadiene phase (B) of the ABS molecule [13,17]. The double bonds in the butadiene phase (B) were broken and produced oxygen-containing groups such as carbonyl and hydroxyl.…”

“…In the study by MANISH et al [13], through mechanical testing of new and recycled ABS with different chemical compositions of SAN and butadiene, it was observed that new ABS achieved the best tensile test results when compared with recycled ABS. In order to improve the tensile performance of recycled ABS, it was necessary to increase the additives of SAN and butadiene in new processes, for which their compositions varied from 5 to 60% physical (SAN) and elastic (butadiene) phases, in order to obtain an improvement similar to new ABS.…”

“…The first parts molded using ABS polymer were sheets, profiles and tubes and, from the 1950s, their use expanded to industrial, automobile, aeronautical areas and nanotechnology [10][11][12]. As such, its applications are conditioned according to the concentrations of each monomer that constitute the ABS; however, the processing conditions can also interfere with the results [13].…”

“…The literature is very extensive in regards to studies on ABS, and includes studies related to degradation [14], composition in recycling [13], behavior in the extrusion process [15], and alternative polymeric mixtures [16] that aim to improve its properties. Using a mechanical analysis, the work carried out by BOLDIZAR and MÖLLER [14] sought to evaluate the degradation of ABS during repeated processing cycles, and it was observed that from the second to the sixth cycle the elongation of the rupture calculated by the tensile test presented a drastic drop, due to the repetitive extrusion processing.…”

ABS resins have wide application in the market, mainly in the manufacture of household appliances, telephones, automotive industry and others, and need to be processed by extrusion for the manufacture of products. The variables used in the process of extrusion of polymers have a direct influence on their mechanical properties. The objective of this study was to evaluate the different speeds of the extruder screw (15, 30, 45 and 60 rpm) on the mechanical properties of raw ABS after the extrusion process. Izod impact resistance and tensile tests, were also performed. The fractures of the samples tested by Izod impact were observed via optical microscopy, scanning electronic microscopy (SEM), and roughness was measured. Calorimetric tests (DSC) and thermogravimetry (TGA), as well as melt flow index (MFI), were also performed. The most significant results were observed for the extruder screw speed of 60 rpm. For the impact test, a reduction in impact energy of approximately 3% was observed, with the same result for tensile resistance. However, an increase in the value of the elastic modulus and the MFI was observed due to the increase in the degree of crystallinity, which was caused by the higher shear of the polymer mass in the screw of the extrusion equipment. Additionally, an atypical case occurred for the ABS polymer in the highest rotation, since it was the polymer that suffered the greatest shear in the polymer chains due to the degradation of the butadiene phase.

Closed‐Loop Recyclable Poly(ester‐disulfide)s for Potential Alternatives to Engineering Plastic

Facile fabrication, low material complexity and closed‐loop recycling are essential for polymer plastics to alter their linear product economy towards a cradle‐to‐cradle one. Covalent adaptable networks (CANs) are one way to achieve that, which intrinsically exhibit decent mechanical properties of the thermosets but could also be easily recycled like the thermoplastics. In this work, we introduce rigid ester structural motifs into dynamic poly(disulfide)s to form a series of dual polymer networks. Owning to the coherence of soft/rigid segments and the reversible sacrificial crosslinking, they exhibit tailorable properties and good resistance towards different chemicals. Their closed‐loop recycling is achieved via mild solvolysis, maintaining materials’ mechanical integrities. It offers a solution as a sustainable replacement for engineering plastics which are massively under production but hard to be recycled.
