Polydimethylsiloxane (PDMS) is a well-known and widely used viscoelastic biomaterial with applications across the tissue engineering and biomedical fields. In general, its use thus far has been limited to applications wherein casting or molding are possible.

Advanced Solutions is now demonstrating PDMS bioprinting with its BioAssemblyBot to create complex shapes potentially useful in a variety of applications. PDMS as a biomaterial Silicone-based polymers have been used in tissue constructs since the middle of the 20th century. Their early use as a replacement bile duct and urethra exhibited the material’s useful qualities: high bio-compatibility and elasticity. Subsequent tissue constructs applications throughout the intervening 80 years have shown that silicone-based polymers, among which PDMS is the most common, are safe, broadly applicable, and economical.

PDMS is characterized by its low surface tension, low modulus (contributing to its biological consistency), hydrophobicity, thermal and electrical stability. Today, PDMS is commonly used in catheter […]
