Vat photopolymerization (VP), as an additive manufacturing process, has experienced significant growth due to its high precision and excellent surface quality. This method enables the fabrication of intricate shapes structures while mitigating machining challenges associated with non-oxide ceramics, which are known for their hardness brittleness. Consequently, VP process ceramics emerged a focal point in research areas. However, absorption, refraction, reflection ultraviolet light by ceramic particles can impede penetration, leading reduced curing thickness posing process. To enhance efficiency success rate this researchers have explored various aspects, including parameters equipment, composition slurries, modification particles.

Coating materials involving nature-inspired compounds or renewable sources have recently attracted vast attention. This article presents the synthesis of modified rapeseed oil (MRO) as a precursor possessing high biobased carbon content suitable for cured thermosets formation. Two reactive diluents based on sources, methacrylated methyl 3-hydroxybutyrate (M3HBMMA) and ethyl (E3HBMMA), were successfully synthesized. Lastly, isosorbide monomethacrylate (MISD) was suggested produced polarity modifier miscible with curable systems capable increasing thermoset surface energy. All synthesized structurally analyzed via NMR, ESI-MS, FTIR. The characterized substances coated paper, stainless steel, beech wood to investigate their suitability forming thin layers. paper dip coating verified diluting properties M3HBMMA, resulting in average formed deviation decrease (87.5% undiluted MRO 28.0% 50 wt % M3HBMMA containing MRO). Also, additional weight decreased from 350 69 same systems. standardized bend test applied steel specimens revealed thermoset's flexibility adhesion increase 12 ± 2° bending angle 100% pure 121 measured 40 E3HBMMA MRO-based thermoset. samples underwent cross-hatch investigating substrate's quality. reached level 1 rating (second worst), while system MISD obtained 5 (the best).

The urban heat island effect raises road surface temperatures, increasing energy demands and accelerating pavement deterioration. This study evaluates a polymer-based system using methyl methacrylate (MMA) resin with aluminum silicate (AS), glass bubbles (GBs), microencapsulated n-docosane phase-change material (PCM) to identify the most effective solution. Indoor laboratory tests determined AS as optimal choice, balancing thermal insulation, workability, mechanical strength. AS-containing mixtures reduced temperatures by ~10 °C exhibited superior compressive strength (28.2 MPa at 6 wt%) compared GB (23.7 4 PCM (27.2 wt%). also maintained stable viscosity ≤10 wt%, unlike PCM, which became unworkable above 5 wt%. AS-based achieved high skid resistance (90.2 BPN), abrasion (0.1% wear after 500,000 cycles), low VOC emissions (69.64 g/L). Adjusting resin-to-BPO ratio 1:0.42 enabled 30 min curing time 25 °C, ensuring practical application. These findings highlight filler for large-scale deployment. Future work should assess long-term durability optimize formulations broader adoption in heat-mitigating infrastructure.
