Mechanical engineer, Marie Adeyemi, helps a team of children to research, design and make some packaging for soft fruit using 2D and 3D design software. Marie has brought in some raspberries to share with the children, but they鈥檝e been squashed at the bottom of her bag. They decide to try and design some better packaging to protect the raspberries. After looking at different boxes and cartons they discuss the purposes of packaging. They look at the pros and cons of the different designs when it comes to soft fruit. One group uses plasticine to model their idea for a row of spikes to hold the raspberries. This will eventually be printed by a 3D printer. An expert comes in to tell them how 3D printers work. They use 3D modelling software to convert the plasticine design to a design which the 3D printer can produce. The other group works on the box to hold the spikes. They use 2D design software to design the net which the box will be made from. They decorate the outside of the box to make it attractive. Finally, their completed design is shown to Marie and the 3D printing expert for their feedback.
