A systematic study of vat-polymerization binders with potential use in the ceramic suspension 3D printing

The primary focus of this study is to offer guidelines for developing binder formulations visible light photoinduced ceramic 3D printing applications. Different monomer combinations with a variety functional groups were mixed at various ratios systematically their rheological and curing behaviour, mechanical properties (ultimate tensile strength, elongation break, Young’s modulus). optimum blends investigated by adjusting the balance difunctional monomers (HDDA Photocentric 27) multifunctional (tri- tetrafunctional - PPTTA, 34 PE(EO)nTTA) weight rates 20:80, 40:60, 50:50, 60:40, 70:30 80:20. key parameters (penetration depth Dp critical exposure energy Ec) calculated fitting values based on thickness (Cd), using Jacobs' Basic Working Curve Equation, estimate time each mixture. Although performance mixtures was enhanced increasing functionality molecular in mixture, best viscosity obtained when trifunctional (meth)acrylates. Two types used showed similar performance. ratio between di- 50:50 40:60 wt ratios, yielding minimum required slurry mixtures. Moreover, effect vinyl-based monofunctional as reactive diluents well hexa-functional cross-linkers shortlisted studied. This work summarises base choices daylight curable suspensions, LCD screen applications, further works mcust be done find debinding cycles.
