Optimization of Vat-Polymerization binder formulation for 3D printing ceramic slurry using D-optimal mixture experimental design

A Systematic Study on Impact of Binder Formulation on Green Body Strength of Vat-Photopolymerisation 3D Printed Silica Ceramics Used in Investment Casting

“…High-functionality monomers’ influence on the mechanical properties of green bodies was studied in previous studies [ 19 , 29 ] with various methods. Even with different approaches such as individual investigation or mixture design strategy to understand the mechanical properties and shrinkage of green parts with high functional groups, similar results were demonstrated on the mechanical and rheological properties.…”

“…However, hig can inhibit the purpose of adding oligomers by making the structure o brittle. Figure 4 depicts an example of a vertically 3D-printed tall cerami the B-37 and 30 wt.% of UA-formulated mixtures; the part with B-37 load after reaching a certain height due to low green strength and flexibility, component printed successfully with the oligomer-formulated formula High-functionality monomers' influence on the mechanical proper ies was studied in previous studies [19,29] with various methods. Even proaches such as individual investigation or mixture design strategy t mechanical properties and shrinkage of green parts with high function High-functionality monomers' influence on the mechanical properties of green bodies was studied in previous studies [19,29] with various methods.…”

“…Despite a handful of studies on the optimisation and characterisation of monomers as ceramic binders [ 4 , 19 , 28 , 29 ], a recent review by Leite de Camargo et al [ 12 ] shows that the effect of oligomers on the viscosity of the ceramic binder systems, curing performance (cure depth) and mechanical properties of printed bodies have not been fully studied so far. Therefore, we aim to extend the investigation conducted in the previous study [ 4 ] by understanding the effect of varying the concentrations of the aliphatic urethane and polyester acrylates on the viscosity of the mix, curing performance of the formulation in the LCD printing process, as well as on the mechanical properties of ceramic prints.…”

Effect of resin composition on cure depth, dimensional accuracy, and surface roughness in Al2O3 stereolithographic 3D printing

“…39 Different combinations of monomers can have a significant influence on the tensile strength, volumetric shrinkage, viscosity, and cure depth. 40 Non-reactive components can also be added to resins to modify their properties. Dispersants, diluents, light absorbers, defoamers, and plasticizers can all be additional components of a photocurable resin.…”

“…25,36,41,42 These plasticizing agents and diluents usually constitute from 10% to 30% of the resin by weight. 25,26,40,43,44 Some plasticizing agents have been found to prevent early evaporation and interact with the thermal polymerization reactions of the reactive components. 44 This study primarily focuses on polyethylene glycol (PEG), which is a common plasticizer and non-reactive diluent.…”
