I obtained my MSc in Material Science and Engineering from K.N. Tousi university, Tehran Iran. My MSc. research was aimed at Modification of the distribution of nanoparticles ZrO2 reinforced Al composite. After perusing my degree I joined Razi Foundation Metallurgical Lab as a lab expert. Also worker as a welding engineer at Kavosh Joosh Company that is a manufacturer of welding instruments and also building some hard-facing plates for one year, a great experience for a material engineer.

I have been Quality Control Manager, R&D expert and also Technical supervisor in 3D printing of medical implants via SLM and CNC at Bonash Medical Company since 2016. My specialties include material characterization for additive manufacturing technology, metal 3D printing, polymer 3D printing, surface modification, and mechanical properties in additive manufacturing process.

Past Scientific Works[edit | edit source]

• Working on selective laser melting parameters to reduce the cost and energy. This project leads to affordable 3-D printing, and enabling low-cost distributed manufacturing for individuals by studying layer thickness, structural design, internal geometrical shape, the rate of porosities, power of optical lasers, and recoating time in Selective Laser Melting machine for Ti alloys.
• Ti anodizing as a thin coating layer for better biocompatibility. Color coding of Ti parts was the first result in this study. The coloring process involved anodizing, which also affected the corrosion resistance of the alloy. The presence of the anodic film enhanced the corrosion resistance of the alloy. This protective layer is very stable and allows the use of titanium in severe working conditions, such as offshore; in an acid environment; in aerospace and automotive industries; in high-temperature applications; in the chemical and food industries; and in marine hydrometallurgical applications and nuclear fuel waste containment, where no other metal can be used. For example, investigation the duration of the passive and anodizing phase
