“…Intensive research is ongoing to develop new resins with cross-conjugated photoinitiators in order to achieve such high resolutions in special structures. [8,9] SLA requires the use of photosensitive resins that have considerably poor mechanical properties, and so the fields of application are generally limited to the production of prototypes with reduced functionality. Since SLA is a fast and accurate technology, it is often used to create skeletal models individually from patient-data to improve surgical planning [10,11,12] or for medical products in contact with the human body, such as otoplastics.…”

“…[13] Surveys [14,15] showed that leachates out of under-cured polymers can cause cytotoxic reactions in vivo, which is one of the reasons why SLA has not yet been used for the production of implants, although though new biocompatible and biodegradable photopolymers have been deployed for cellular bone replacements. [16] For instance, spongiosa-like structures could be easily created out of patient-data. [17] In addition, there are new resins commercially available that may be of interest.…”

“…[19][20][21] Furthermore, they exhibit excellent optical properties and biocompatibility, thus being a perfect material for micro-optical and biomedical applications. [22][23][24][25][26] For synthesis, alcoxysilane-precursors undergo hydrolysis and polycondensation reactions resulting in an organically modified inorganic-oxidic network ([Si-O] n ).…”

“…in vacuum) mainly to lower the refractive index of the cladding material. [12,13] In our process, it is sufficient to UV-flood-cure the remaining unreacted monomer, creating an interpenetrating network of silicone rubber with lower content of high refractive thiol-ene photopolymer in the cladding region than in the core (Figure 1). …”

“…Hence, this orthogonal reactivity yields a low refractive silicone rubber with a high refractive, two-photon-sensitive resin inside, which is a practical improvement over works from the past, where this was achieved by a time consuming and unreliable swelling step. [12] After selective curing of the PDMS matrix material, the waveguide structures are inscribed by inducing a local refractive index change by means of 2PP-thiol-ene curing. Upon two-photon-illumination high refractive thiol-ene material becomes enriched in the waveguide region via diffusion.…”
