Rahi, Ved & Ohm's 3D Printing Learning Story

Learners: Rahi, Ved & Ohm     Learning Coach: T.Dillner           Date: 21.9.15

Learning Area: Technology - 3D Printing

Learning Observed

Rahi, Ved and Ohm chose to participate in 3D Printing during iExperience during Week 7-10 this term. We initially learnt about the Thinker’s Key called ‘BAR’. BAR stands for Bigger, Add, Replace. To practise, the learners had to pick either a pen, lunch box or tennis racquet to make a feature bigger, add to the item and replace something. The learners had as much creative license as they needed and then they reflected on how functional the item had become - could it still be used for its original purpose? The next stage was to come up with an item that we use at school and repeat the BAR process. Rahi, Ved and Ohm decided on a upgrade to the wheelie chairs we have in our habitat. Rahi, Ved and Ohm had to use the website TinkerCad to design their new and improved chair. They had to use the pre-existing shapes to form their 3D model which was then printed out by our LH1 3D printer. After analysing their printed model, the boys were able to write a description about who would use it, why they designed it and what its features were. They also spent some time reflecting on improvements and redesigning it on TinkerCad to show these changes.

Key Competencies/Vision Principles

Rahi, Ved and Ohm were collaborative during this process by sharing ideas and coming up with other ways to show creativity (Thinking, Participating & Contributing). They demonstrated curiosity by engaging with the entire technology process of designing, making, redesigning and evaluating. Rahi, Ohm and Ved were connected as they were able to show their learning in three different mediums (paper, digital and printed model).

Next Learning Steps

Complete the second design on TinkerCad and print if time allows. Use the 3D printer as a component of an iExplore. Create a tutorial video to teach other learners in the habitat how to use TinkerCad.
