3D printing of silicone and polyurethane elastomers for medical device application: A review

Post-Wear Surface Morphology Assessment of Selective Laser Melting (SLM) AlSi10Mg Specimens after Heat Exposure to Different Gas Flames

“…The term additive manufacturing (AM) is most commonly renowned with the word 3D printing with the help of layer-by-layer deposition of material in the creation of prototypes and complex geometries along with controlling waste over substantive manufacturing and customized production [1]. This technology has equal applications for all types of industries but especially demanding for aerospace, medical, electrical vehicles, and critical jigs and fixtures production.…”

Application and Properties of Polyglycolic Acid as a Degradation Agent in MPU/HNBR Degradable Elastomer Composites for Dissolvable Frac Plugs

“…Downhole packers, integral to sealing mechanisms, necessitate the selection of appropriate soft materials of high molecular weight to ensure seal integrity, reduce operational disruptions, and mitigate costs and safety hazards in oil production. Materials such as millable polyurethane rubber (MPU) [ 13 , 24 ], hydrogenated nitrile butadiene rubber (HNBR) [ 25 ], nitrile butadiene rubber (NBR), fluoroelastomer (FKM), and ethylene propylene diene monomer (EPDM) are instrumental in these applications [ 26 , 27 ]. Notably, HNBR, with its extensive saturation and high-performance profile, is favored in oilfield isolation seals owing to its superior thermal stability, resistance to high temperatures, longevity, oil resilience, and defense against acid gas corrosion.…”

Developing tuneable viscoelastic silicone gel-based inks for precise 3D printing of clinical phantoms

“…Thus, these properties are important for creating long-lasting and realistic phantoms that accurately simulate the properties of human tissues. For example, silicone has been used to replicate the internal structure of the human bronchial vasculature 43 due to its versatility in tensile strength (ranging from 0.2 to 165 MPa, with PDMS being the gold standard at 5 MPa), 44 and elongation at break (5% to 1490%). 44 However, intrinsic issues of silicone processing, such as its high viscosity for formulations of higher elastic modulus, and the complexity of controlling the polymerization reaction, make it more challenging to process silicone formulations through 3D printing, relegating the fabrication of complex structures to more simple fabrication procedures such as casting.…”
