Chulalongkorn University Internship
Chulalongkorn University, Faculty of Engineering
May 2023 to June 2025
About Chulalongkorn University & My Role
My research internship at Chulalongkorn University involved working alongside the Faculty of Engineering on the development and optimisation of 3D-printed lattice structures for medical and assistive applications, particularly diabetic-ulcer orthotics and deep-sleep equipment.
I worked as a student research contributor, and throughout my time with the project, I had:
-
Designed and 3D-printed multiple lattice structures, exploring how geometry, angle, scale, and distribution influence compression, durability, and structural performance
-
Conducted mechanical testing alongside the Faculty of Petroleum and Petrochemical Engineering, using Universal Testing Machines and medical equipment to measure compressive stress, strain, displacement, force, and pressure
-
Contributed original lattice designs towards research on diabetic-ulcer orthotic shoe structures and the optimisation of pressure distribution and comfort
-
Curated and produced conference research submissions, including the paper “Lattice Optimization for Designing Diabetic Ulcer Orthotics” for the International Society of Biomechanics ISB2025 Congress
-
Collaborated with leading professors and Chulalongkorn Hospital personnel to explore the translation of 3D-printing research into practical orthotic equipment for diabetic-ulcer patients
-
Conducted patient-oriented interviews and market research to understand practical requirements for assistive medical equipment
-
Assisted with 3D-printing software training at Chulalongkorn Hospital, supporting the application of additive manufacturing within a clinical environment
-
Extended my research into deep-sleep applications, producing lattice structures for research into potential memory-foam and internal pillow structures
Project Description
Conducted engineering research at Chulalongkorn University focused on 3D-printed lattice structures for medical applications, including diabetic-ulcer orthotics and deep-sleep equipment. The project combined computational design, additive manufacturing, mechanical testing, patient-oriented research, and market analysis to investigate how lattice geometry and material structure could be optimised for comfort, durability, pressure distribution, and clinical application.
Impact
-
Curated and prepared a main conference submission for the ISB2025 Congress of the International Society of Biomechanics titled “Lattice Optimization for Designing Diabetic Ulcer Orthotics.”
-
Produced additional Chulalongkorn University conference and research submissions based on experimental work investigating lattice optimisation for diabetic-ulcer orthotic applications.
-
Designed and 3D-printed multiple lattice architectures for integration into shoe-sole and orthotic structures, investigating the effects of lattice angle, dimensions, scale, geometry, and distribution.
-
Conducted mechanical testing of lattice structures alongside Chulalongkorn's Faculty of Petroleum and Petrochemical Engineering, using Universal Testing Machines and medical equipment to evaluate compressive stress, strain, displacement, and applied force/pressure.
-
Investigated Poisson's ratio, compression–strain behaviour, structural durability, and cracking characteristics across different lattice configurations to inform design optimisation.
-
Contributed original 3D-printed lattice designs to university research exploring the use of structured lattice materials in deep-sleep applications, including potential memory-foam/pillow internal structures.
-
Collaborated with Chulalongkorn Engineering professors and Chulalongkorn Hospital personnel on the development and application of 3D-printed medical/orthotic equipment for diabetic-ulcer patients.
-
Conducted patient-oriented interviews and market research to identify practical requirements and usability considerations for diabetic-ulcer orthotic equipment.
-
Assisted with 3D-printing software training at Chulalongkorn Hospital, supporting the translation of additive-manufacturing research into practical medical applications.
-
Continued research from February 2023 through June 2025, developing progressively more advanced lattice designs and experimental methods across multiple university research applications.
