AI Technical Summary

Benefits of technology

This patented technology improves upon existing methods used with polymerizable resin compositions such as vinyl acetate (VAC), but it also introduces new features that make them more effective at producing stronger products while reducing their environmental footprint compared to traditional methodologies like casting or injection molded parts made from these types of materials. Additionally, there are advantages associated with combining different components together into one structure instead of creating separate structures separately due to its unique chemical composition. Overall, this innovation provides technical benefits over current technological means.

Problems solved by technology

This patented describes three technical problem addressed by this patents: Firstly, while some conventional printers require multiple different type of consumers like those made entirely out of specialized polymers called thermoplastic elastometers or solvent casting resin, they cannot be reused without losing their effectiveness over time because these consumptions contain harmful chemical substances produced through burning processes. Secondly, even if we could create a stronger base layer on top, current methods may result in collapsing surfaces when trying to remove fillings inside layers. Thirdly, combining certain components together into a composition helps achieve desired results despite being limited resources at once.
