3D Printing Junior Challenge: Cookie Cutters Revised

 

Yesterday we wrote about how we had attempted to develop the students skills by developing the challenge of creating a suitable 'cookie cutter' task.   The first example came out, being the print shown left.   We were then able to give the students the opportunity to test the print by applying it to Play-doh to check the imprint.

The initial print quickly proved to be lacking in details and was somewhat difficult to push into the play-doh.   The student responsible for this design then spent time looking at what they needed to do to improve the design and make it effective.  There second version of the print is shown left next to the original.

As we described yesterday the original was 50mm across 90mm high and 3mm wide.   The revised version was 110mm high 60mm across and 10mm thick.   The original took fifteen minutes to complete the revised version was forty five minutes on the Bambu H2D.

We also detailed a significant development with the design shown left that was a virtual design from the previous post.   This example was also printed on the Bambu H2D and took seventy five minutes.   This version (which features a significant handle 160mm high, 60mm wide and 20mm thick.

Observing the play-doh (left) while the shape of the tree can be seen from the imprint of the cutter the student has indicated that they potentially would like to develop the dimensions further.   Technically the star that sits on the top of the tree is too big for the design.

This project has been worked on by seven and eight year old students working with their iPads, using the Tinkercad app and printed on the Bambu H2D.
