研究目的
Investigating the kinetics and modeling of dual-wavelength (UV and blue) controlled photopolymerization con?nement (PC) for 3D printing applications.
研究成果
The study demonstrates that without the UV-light, higher initiator concentration and rate constant lead to higher conversion. The UV-light serves as the turn-off mechanism for spatial con?rmation within the overlap area of UV and blue light. A theoretical new ?nding for the criterion of a good material/candidate governed by a double ratio of light-intensity and concentration, [I20C20]/[I10C10], is developed.
研究不足
The study excludes the oxygen inhibition effect, which is important especially in thin polymers. The modeling is based on ideal kinetics and excludes other complex factors involved in the measurements.
1:Experimental Design and Method Selection:

2:Sample Selection and Data Sources:
The study uses methacrylate conversion data under the exposure of blue and UV light for various resin formulations.
3:List of Experimental Equipment and Materials:
The study involves the use of blue (470 nm) and UV (365 nm) light sources, photoinitiators (PA), co-initiators (PC), and photoinhibitors (PB).
4:Experimental Procedures and Operational Workflow:
The system is subject to continuous exposure of blue light and on-off exposure of UV light to study the photopolymerization con?nement.
5:Data Analysis Methods:
Analytic formulas and numerical simulations are used to analyze the conversion e?cacy and inhibition effects.
