Our research vision...

3D printing for personalised nutrition | Stephen Homer

Self tracking for diet and exercise

5 | 3D printing for personalised nutrition | Stephen Homer

Could future sensors provide additional and more automated tracking?

Focus on highly nutritious foods:

• High protein
• Smaller serves with a high

nutrient loading

• Use of novel ingredients

Does structure affect digestion?

10 | 3D printing for personalised nutrition | Stephen Homer

 Currently working on various protein gel structures  Investigating their rates and extent of digestion  Uses in vitro techniques for gastric and intestinal stages

What might the future look like?

11 | 3D printing for personalised nutrition | Stephen Homer

One printer to print many types of foods using different “trigger mechanisms”

Could this be the next food revolution?

 Temperature control (heating and cooling)  Multi-channel extrusion  Extrusion of different material types  Consideration of microbiological safety

• Ingredient storage
• Cleaning

Challenges
