Description
The field of additive manufacturing (AM) has seen tremendous growth in its possible applications with the introduction of multi-material 3D printing, which may be used to prototype complex structures and sophisticated geometries which improves the performance and adaptability of printed components in various sectors. Despite these developments, the broad-spectrum of materials for AM are mostly derived from petroleum oil which limits the technologies and economic viability for widespread application. In this context, vegetable oil is a renewable alternate feedstock for 3D printing due to its broad spectrum of applications, affordable price, and potential biodegradability. In this piece of work, we demonstrate the development of soybean oil-based photo-curable resins (ESBO_HEA/HEMA) for application in digital light processing vat photopolymerization. At first, epoxidized soybean oil (ESBO) was converted into acrylated/methacrylated soybean oil (ESBO_HEA/HEMA) by one-pot oxirane ring opening processas an alternative to conventional acrylated epoxidized soybean oil (AESO) generated via acrylation between ESO and acrylic acid. A series of 3D printable DLP inks have been formulated using synthesized resins (ESBO_HEA/HEMA) in the presence of photoinitiator (TPO) and or, reactive diluents (Trimethylolpropane triacrylate). Moreover, the resin's viscosity of all formulated inks was investigated which are in good agreement with DLP 3D printing. Additionally, the impact of reactive diluents (TMPTA) on the thermal (DSC, TGA) and mechanical (DMA, tensile strength, and hardness) behavior of the 3D-printed object was also examined. After adding the TMPTA behavior of the materials is changed. It shows high mechanical properties, which are 4.17 MPa in ESBPO_HEA and 4.10 in ESBO_HEMA. Altogether, this work demonstrates the use of bio-based and inexpensive soybean oil which offered a simple method to prepare potential inks for DLP 3D printing that could be used in the additive manufacturing industry to make architectural models and automotive components which opens new avenues for sustainable 3D printing.
