FifeX asked us to help with an educational project for SEPA (Scottish Environment Protection Agency). They wanted some bespoke models to help to educate schools and other groups about flooding and its effects including broken trees, damage to property including buildings and vehicles, and infrastructure like roads. These models would have to be robust and stand up to handling by groups of all ages.
Fifex knew that Perspex would be perfect for the job. It can be sourced in a wide range of colours and can be cut into intricate shapes. They decided on 5mm thick Perspex to make the shapes sturdy, and they designed the pieces so that the car, house and tree shapes could slot into bases. 3D models would have more impact and make them easier to handle.
A good fit
The main challenge was to make sure that the tabs and slots on the shapes and the model bases fit together well. If they were too loose, the models wouldn’t be robust enough when glued together. If too tight, they wouldn’t fit together at all! When materials are laser cut, the width of the cut is determined by the nature and thickness of the material. It’s always worth checking the artwork by making prototypes so that dimensions can be adjusted if necessary. Also, material thicknesses can be nominal and have margins for error, so it’s always worth checking. In this case, we got it right first time and the fit was perfect.
Ken Boyd, Director of FifeX, said, ‘Laser cutting the shapes was a fantastic solution for us as the models were to look accessible for a young audience with fun, interesting and recognisable shapes. Brightly coloured Perspex was the perfect material. LaserFlair helped us with initial prototyping and a very quick turn-around on the final product as well as some spares and extra bits.’
