Abstract
Ink Jet Based Infra-Red Sintering (IBIS) is a powder-bed-fusion based additive manufacturing (AM) technology. In IBIS process, a thermal radiation absorbent material (RAM) solvent is selectively printed on the surface of a powder layer using the inkjet technology followed by the sintering of powder with infrared lamps. This research is carried out to study the effect of sintering time on mechanical properties of parts and thermal characteristics of IBIS Process. To study the effect of sintering time, a thermal control system and a modified inkjet printing system are installed into the in-house developed IBIS machine to fabricate tensile-test samples based on ASTM D638. Tensile tests were conducted, and data shows that as the sintering time increases, mechanical properties of parts increase. To study the thermal character of the IBIS process, a numerical model which agrees well with the experimental data is established using Abaqus 2018. Using the numerical model, it is discovered that as the layer increases, the temperature of the white powder increases.
