Abstract:
The effect of incubation temperature on the print performance, rheological properties and microstructure of beeswax-carrageenan-xanthan hybrid gelator inks were studied. When the incubation temperature increased from 25 to 35 ?, the crystal structure of beeswax transferred from amorphous to spherulites. The beeswax particles in hybrid gelator inks were evenly dispersed and tend to aggregate. The hybrid gelator ink's tau(0) and n increased from 23.64 to 33.63 Pa and 0.20 to 0.26, respectively, which indicated that the inks have low mechanical strength and were not conducive to molding. When the incubation temperature exceeded 55 ?, a large number of needle-shaped crystals appeared in the beeswax, and the solid fat content increased from 29.98 to 30.60% (p < 0.05). The beeswax was fused to form larger particles, and an interpenetrate/penetrate network was observed on the beeswax surface. The increasing K and n indicated that the inks have larger particles and high viscosity and were adverse to extrusion. When the incubation temperature reached 45 C, spherulites and needle shaped crystals simultaneously appeared in the ink. The ink's tau(0), K and n values were 113.44 Pa, 248.40 Pa.s(n) and 0.34, respectively. Inks can be squeezed out smoothly and have good filament fidelity. The hollow cube model was printed with good shape retention. This article provides a methodology for the development and application of novel hybrid gelator system in 3D printing.
