Subash Panta

Manufacturing Engineer for Halo labs, responsible for:

• Responsible for researching high-temperature filaments for 3D printing, including ULTEM 1010, and customizing 3D printers for high-viscosity liquid printing after identifying suitable materials.
• Conducted studies on nanoporous thin film membranes for biotech sample filtration, and performed tensile and flexure tests on various plastic membranes.
• Skilled in 3D printing across different temperature materials, and troubleshooting issues like bed leveling, nozzle and bed temperature inconsistencies, and temperature gradient warping.
• Managed the production of 96-well plates, ensuring precision with advanced pneumatic fixtures, high-precision glue guns, and proximity sensors.
• Provided training for technicians on fabrication machines and screen printers, developed SOPs, and supervised daily production, addressing issues such as glue gun clogs and printing defects.
• Designed and implemented a 3-axis cutting machine in SolidWorks, featuring dual X/Y rails and a pneumatic Z-axis slide, achieving 100% accuracy and increasing production speed by 80% with a Python-controlled Arcus controller

• Proficient in material testing of metals, composites, and polymers following ASTM standards, with a focus on data analysis.
• Experienced in the manufacturing of 3D printing filaments using both twin-screw and single-screw extruders.
• Produced ASTM-standard tensile and flexure samples with injection molding machines using Nylon-6 and PLA pellets.
• Created glass fiber-reinforced polyester matrix composites through vacuum infusion and compression molding.
• In-depth understanding of prepreg materials and their specific curing cycles for composite production.
• Skilled in manufacturing advanced composites, such as carbon fiber and glass fiber materials.
• Worked with a variety of polymers, including thermoset types like unsaturated polyester, EPON 828 epoxy, cyanate ester, and thermoplastics like Nylon-6, Nylon-12, ULTEM 1010, PEEK, PLA, and ABS.
• Conducted and published research on 3D-printed bio composite filaments made from Ragweed and PLA.
• Competent in thermal characterization techniques, including TGA, DSC, and TMA.
• Utilized SEM to examine fiber/matrix bonding.
• Served as a lab instructor, teaching Polymer Nanocomposites and Polymer Properties & Processing courses, focusing on composite manufacturing, mechanical testing, and data analysis.
