3D printing of materials which combine fracture toughness, high modulus and high strength is quite challenging. Most commercially available 3D printing resins contain a mixture of multifunctional (meth)acrylates. The resulting 3D printed materials are therefore brittle and not adapted for the preparation of denture bases.

- Color stability is essential in dental materials for a perfect match with a patient's tooth color, but it's especially difficult in photoresist-based 3D printing.
- This study examines the intrinsic causes of discoloration by testing thin-film samples of different compositions under various storage conditions and monitoring changes using UV-Vis absorption spectra.
- Findings highlight that both material composition and storage conditions affect discoloration, and using certain photoinitiators and stabilizers, along with an oxidizing agent, significantly improves color stability in the materials.
Here, the development of an adhesive is reported - generated via free radical polymerization - which can be degraded upon thermal impact within minutes. The degradation is based on a stimuli responsive moiety (SRM) that is incorporated into the network. The selected SRM is a hetero Diels-Alder (HDA) moiety that features three key properties.
