Auxetic Materials in Unit Cells

"Smart structure" with flexible, yet strong properties

Breast Scaffolds

3D printable, biodegradable breast scaffolds for implantation designed from .gcode raster-based patterns

3D Scanning

Extrusion

  • Traditional Method
  • Soft and Hard extrustion
  • Greatest Material Range

PhD Project

Triply Periodic Minimal Surface Structures

Powder Based

  • Most Accurate Method, hard to detect layers
  • Metal 3D printing

Light Curing

  • DLP: Digital Light Processing
  • SLA: Stereolithiography

Mathematically modelled "Smart Scaffold" with high porosity and strength

My own Adventure

Example Prints

To explore different design principles for scaffold design in Tissue Engineering

- Trial and error

- Experimentation

- Kits are very cheap,

<$500AUD

Different Layering Additive Manufacturing Techniques

What is 3D printing?

Our Experience

PhD Project

Limitations

  • Material Choice
  • Directional weakness
  • Shape limitations

How can Additive Manufacturing be useful for you?

Outcomes for today

  • Evaluate participant files
  • Find out your areas of interest
  • Follow 3D printing process
  • Live 3D printing demo
  • No waste
  • Greater intricacy in shape with no extra cost, Freedom of design
  • Fast, inexpensive
  • Legacy IP, new ideas, rapid design prototyping
  • Accurate research models for display
  • Replacement plastic parts
  • Custom work aids
  • Business "cards"
  • Custom gifts
  • Prototyping products

How can this be useful for you?

3D Printing

Free Model Websites

Additive Manufacturing: "Manufacturing for design"

- Freedom of Design

- Minimal material wastage

- Greater variety of structural properties achievable

- Supports can be used for generating overhang structures

What services are available?

3D Model Software

Many free, open source and paid options available all the way along the production chain.
