Objective:
To investigate the printability and mechanical performance of silicone under three different material modifications using the Brinter 3D printer, and evaluate the structural differences through basic mechanical testing on dogbone-shaped samples.
Description:
The student will begin by conducting a literature review to understand existing methods for 3D printing silicone and the effects of material additives on printability and mechanical performance. Using the Brinter 3D bioprinter, silicone will be printed under three different material conditions. Optimal printing parameters will be determined experimentally for each formulation. Once established, standard dogbone-shaped samples will be fabricated for mechanical characterization. These samples will undergo basic testing to evaluate tensile strength, elongation at break, and stiffness. The results will be compared across formulations to assess how each modification influences both print quality and mechanical behavior. Findings will inform recommendations for future soft robotic applications and will be compiled into a detailed thesis report.
Background of the student:
The candidate should ideally have a background in mechanical engineering, biomedical engineering, or a related field. Familiarity with the following software and skills is advantageous:
- CAD software: Solidworks, Fusion 360, or similar for design
- FEA: ANSYS, COMSOL, or Abaqus for simulations
- Fabrication Tools:
- Experience with 3D printing
- MATLAB or Python for processing experimental data and creating plots
