The WMG Outreach team, funded by the lmagineering Foundation, has delivered a special CAD and 3D printing programme to more than 200, ten and 11 year olds across Coventry and Warwickshire.

Four University of Warwick undergraduate engineering students delivered the programme, throughout 2019, in a series of workshops designed to raise awareness and knowledge of CAD and 3D printing.

Workshop 1: Introduction to the programme and learning about 3D printing

In the first session the team explained the role of engineers in the design process. The children were also shown how 3D printers are used to create prototypes.

Ice lollies!

In small groups the children were tasked with designing, (using CAD), and creating, (using 3D printing), an ice-lolly drip tray. During the design process the Outreach Team explained the importance of taking accurate measurements to ensure that the designs would actually work.

The challenge

Using a hairdryer (to create the feel of a warm summer’s day!) the children were presented with the problem of dripping lollies! The challenge to design a suitable drip tray was then set.

The children used life-sized 3D printed ice lollies on sticks to take key measurements needed for their drip tray designs. The pupils discussed and sketched design ideas including adding key measurements. These measurement and design sheets were then used in the next two workshops to help develop their CAD designs.

Workshop 2: Using Tinkercad to draw lolly drip tray designs in CAD

A video tutorial was used to show the children how to use Tinkercad. Building on their design work from Workshop One, the children began producing CAD drawings for the drip trays.

Workshop 3: Using scaled digital lolly model to assess and improve designs

Pupils put the finishing touches to their designs and used the scaled digital lolly models to visualise and assess their designs, considering any design modifications that were needed to ensure the drip tray was effective. The children were encouraged to continue this process until they were confident the design would work.

Towards the end of the workshop, the class shared their finished designs. The class then voted for their favourite two, these were then 3D printed and returned to the school as a momentum.

Diane Burton, Project Officer STEM Outreach explained: “The school pupils had fun learning key design principles, and they have successfully produced products that are both functional and creative.”
