Recyclable and reprintable biobased photopolymers for digital light processing 3D printing

Guoqiang Zhu et al.

Summary: Developing recyclable biobased photopolymers for UV-curable 3D printing is essential for the sustainable development of the industry. Novel recyclable and reprintable castor oil-based photopolymers were successfully developed, which can be recycled at specific temperatures without the need for catalysts or solvents. The recycled resins have similar properties to the original resin, allowing for further printing. Additionally, the optimal biobased resin also enables the creation of reprintable sacrificial molds and thermochromic materials.

Spatial and Temporal Control of Photomediated Disulfide-Ene and Thiol-Ene Chemistries for Two-Stage Polymerizations

Shafer M. Soars et al.

Summary: A new strategy combining photomediated thiol-ene and disulfide-ene-based polymerization reactions is reported for the design and synthesis of high sulfur-containing materials for potential use in covalent adaptable networks and optical materials. By taking advantage of the relative reaction rates and semiorthogonally performing these reactions, controlled architecture polymer networks were produced. The study demonstrates the differential reaction rates between thiol-ene and disulfide-ene reactions, enabling spatial and temporal manipulation of material properties through dual-cure networks and photopatterning.

Relaxation of Vitrimers with Kinetically Distinct Mixed Dynamic Bonds

Laura Porath et al.

Summary: Designing materials with tunable modulus and viscosity is crucial for various applications. Vitrimers, with their dynamic bond exchange mechanism, provide an ideal platform for viscoelastic design. By using different cross-linkers with varied functionalities and kinetics, control over cross-link density and exchange kinetics can be achieved. Furthermore, combining multiple cross-linkers into a single network allows for a better understanding of the effect of multiple dynamic bonds on the viscoelastic response.

Benjamin J. Carberry et al.

Summary: This study characterizes the thiol-thioester exchange reaction in cross-linked poly(ethylene glycol) (PEG) hydrogels and identifies the significant role of network thiols liberated from exchanged thioester cross-links in hydrogel degradation, resulting in predictable changes in the storage modulus and nonideal mass loss profiles. These findings enable the design of on-demand degradable hydrogels with uniquely tunable degradation and mass loss.

Stereochemistry-Controlled Mechanical Properties and Degradation in 3D-Printable Photosets

Anissa L. Khalfa et al.

Summary: Stereochemistry is a powerful tool to modify the mechanical properties and degradation rates of photocurable materials by controlling the stereochemistry of pre-resin oligomers. The synthesis of stereopure pre-polymers and retention of stereochemistry during UV-triggered crosslinking enable the formulation of materials with different mechanical properties. This approach allows for the creation of high-resolution, three-dimensional printed scaffolds with varying stiffness, toughness, and degradability from the same components.
