Additive Manufacturing (AM) technologies have been emerged as a fabricationmethod to obtain engineering
components within a short span of time. Desktop 3D printing, also referred as additive layer manufacturing technology
is one of the powerful method of rapid prototyping (RP) technique that fabricates three dimensional engineering
components. In this method, 3D digital CAD data is converted directly to a product. In the present investigation, ABS +
hydrous magnesium silicate composite was considered as the starting material. Mechanical properties of ABS + hydrous
magnesium silicate composite material were evaluated. ASTM D638 and ASTM D760 standards were followed for
carrying out tensile and flexural tests, respectively. Samples with different layer thickness and printing speed were
prepared. Based on the experimental results, it is suggested that low printing speed, and low layer thickness has resulted
maximum tensile and flexural strength, as compared to all the other process parameters samples.
