Bio-Based UV-Curable Resins

Bio-Based UV-Curable Resins Used in Three-Dimensional (3D) Printers The production of three-dimensional (3D) printers is one of the most important technological developments of our time. The market, which was valued at USD 13.84 billion in 2021, is expected to reach USD 21.5 billion by 2030. In recent years, its use in our daily lives has been increasing due to advantages such as low cost, ease of use, and time savings. The production of materials with complex geometries that cannot be made by hand using computer programs without requiring expertise offers significant advantages by reducing costs such as mold expenses, production investment, labor costs, and transportation. Classification can be made according to the technology used in 3D printers. Among these are Fused Deposition Modelling (FDM), Poly Jet Model (Additive modelling), Selective Laser Sintering (SLS), Stereo Lithography Apparatus (SLA), Laminated Object Manufacturing (LOM), and Binder Jet techniques, which are present in the market. While the FDM model has a wide place in plastic parts production, Poly Jet and SLA technologies, which offer easy use, high-speed production, and high quality, are being used intensively in production as well as home and office applications. The varieties and usage amounts of ultraviolet (UV) curable acrylic and epoxy resins used in Poly Jet and SLA technologies are increasing every day. The UV-curable acrylic resin market size was USD 4.6 billion in 2021 and is expected to reach USD 7.3 billion by 2026. In this growing market, there has been a significant increase in the use of bio-based chemicals due to factors such as environmental and human health concerns. Due to the depletion of petroleum and petroleum derivatives and their harmful effects on the environment and human health, the use of sustainable, biodegradable, non-toxic, and environmentally friendly bio-based chemicals has become widespread. Looking at the resins used in 3D printer technologies, there are efforts to develop alternative bio-based chemicals to replace bisphenol A glycol dimethacrylate (Bis-GMA) and ethoxylated bisphenol A dimethacrylate (Bis-EMA), which are frequently used in dental adhesives and composite fields. While developing 3D-compatible monomers by modifying many chemicals such as 2,5-furan dicarboxylic acid, vanillic acid, eugenol, tannic acid, and itaconic acid with acrylate modifications, these monomers are being used in the preparation of UV-curable resins using polymers prepared from these monomers. The use of acrylic resins obtained through modification of natural phenolic products and oils in 3D technology is increasing. Research on the production of UV-curable bio-based acrylic resins is being conducted at İzel Kimya Research and Development Centre. The development of resins and monomers from bio-based chemicals suitable for 3D technology will provide advantages in many fields such as dentistry, coatings, paints, and molds, and will contribute to a sustainable economy.
