Abstract
Utilization of photopolymerization in 3D printing meets with a growing interest in new areas [1]. One of such area is dentistry and orthodontics [2,3]. Development of application in such a demanding area implies invention the search for new materials, additives and photoinitiators which will meet the requirements such as low toxicity, high durability or biodegradability, water solubility. Photoinitiators are crucial ingredient in compositions for materials preparation with 3D printing. They are responsible for monomers curing. From the point of view of their application in 3D printing, the most important feature of initiators is location of maxiumum of absorption band. Currently used printers use light from visible region of electromagnetic spectrum. Light from this region has another advantage which is deeper penetration of material/composition in comparison with light from UV [4]. Most of currently used photoinitiators absorb light in UV therefore development of new photoinitiating compounds is necessary. Excellent strategy to reach this goal is to use more efficient chromophores in structure of photoinitiators [5,6]. Such approach allows to red-shifts absorption characteristics even about 100nm. In this work, we present new photoinitiators equipped with new type chromophore which are able to photoinitiate photopolymerization of monomers in visible light. They have been characterized in terms of absorption properties as well as its activity toward different monomers and proposed application in 3D printing. These new compounds have desire absorption at 405nm which is most common wavelength used by 3D printers. They can be used in 1%wt concentration to fully polymerized desire material.
