Description
Additive Manufacturing for Medical Innovations introduces students to different additive manufacturing techniques [3D printing, lithography, thin film deposition, etc.] and their application in biomedical engineering. Students develop expert skills in “SolidWorks”, and also learn how to use “SolidWorks simulation” for mechanical characterization which allows them to perform engineering optimisation for the designed prototype before fabrication. Students use 3D printing to fabricate their final prototype with optimized characteristics.
The subject includes two project streams. Student teams [group of 4 or 5] to select one project stream for their final assessment]:
Project Stream 1: Spinal cage design, optimization, and fabrication [Addressing Lower back pain]
Project Stream 2: Internal Fixation design, optimization, and fabrication [Addressing broken bone fixation]
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
| 1. | Apply both human and engineering factors to optimise quality of life. (B.1) |
|---|---|
| 2. | Apply clinical and biomechanical knowledge of musculoskeletal disorders, in particular, degenerated spinal discs and surgical fusion treatment as well as internal fixation [bone plates] for bone fracture. (C.1) |
| 3. | Propose biomedical design problem solution with SolidWorks [basic and advanced] and breadth of knowledge about different additive manufacturing techniques. (D.1) |
| 4. | Collaboratively manage biomedical engineering projects to professionally communicate findings. (E.1) |
Course intended learning outcomes (CILOs)
This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):
- Socially Responsible: FEIT graduates identify, engage, and influence stakeholders, and apply expert judgment establishing and managing constraints, conflicts and uncertainties within a hazards and risk framework to define system requirements and interactivity. (B.1)
- Design Oriented: FEIT graduates apply problem solving, design thinking and decision-making methodologies in new contexts or to novel problems, to explore, test, analyse and synthesise complex ideas, theories or concepts. (C.1)
- Technically Proficient: FEIT graduates apply theoretical, conceptual, software and physical tools and advanced discipline knowledge to research, evaluate and predict future performance of systems characterised by complexity. (D.1)
- Collaborative and Communicative: FEIT graduates work as an effective member or leader of diverse teams, communicating effectively and operating autonomously within cross-disciplinary and cross-cultural contexts in the workplace. (E.1)

Teaching and learning strategies
Additive manufacturing [AM], is a production process [technology] that relies on transmitting digital data to a machine [mainly 3D printers] to produce 3D objects layer by layer. AM can address the growing concerns [such as inefficient use of materials, environmental waste, sustainable development, etc.] over traditional production methods.
In the field of Biomedical Engineering, AM offers great potential for personalized and customized treatments. It is possible to develop a wide range of healthcare products including implants, medical instruments, etc. while tuning their mechanical, materials, and biological properties.
This subject provides interactive lectures [Week 1: L1 - An introduction to additive manufacturing and its applications, Week 1: L2- Clinical case studies, Week 1: Practical 1 – Basic SolidWorks; Week 2: L1 - Soft Lithography [Photolithography and PDMS casting], and thin film deposition, Week 2: Practical 2 - Advanced SolidWorks; Week 4: L1 - 3D printing: from macro to micro scale]. In week 1 [L2] students will be exposed to two different clinical problems and two Project Streams will be introduced to them [student teams will select one Project Stream for their final presentation]:
Project Stream 1: Spinal cage design, optimization, and fabrication
Project Stream 2: Internal Fixation [bone plate] design, optimization, and fabrication
In addition to lecture, the subject offers two design workshops in week 3 and 4: Workshop 1: Microfluidics, and Workshop 2: Microneedles. In week 3 student team will use SolidWorks to design a microfluidic system and a microneedle array. In Week 4, student teams will fabricate their microfluidic design using PDMS casting.
In week 5, students will visit the Research and Prototype Foundry at the University of Sydney. During the facility tour, they will fabricate the microneedle arrays that they designed in week 4.
Week 6 is Mid-term presentation [poster presentation]. It is expected that student teams present the clinical background [literature review relevant to the Project Stream], identify the gap, explain their additive manufacturing strategy to design and fabricate the relevant implant [spinal cage or bone plate], and describe their initial design concept and their research questions.
From week 7 to week 11, student teams will work on design, perform mechanical characterisation and engineering optimisation [using advanced SolidWorks], fabricate the implant model and get their project ready for the final presentation.
