|Stationary Holder: Prior to removal of the 'rafting'|
Considerable time is spent with the students prior to printing. There needs to be an identified purpose and an original or personalised design. The students are encouraged to think about the scale of what they are completing relative to the design in question. The print shown left is intended as a stationary storage device. The student designed it from scratch using a rectangle as the base, and then adding a cylinder and a cube for storage on the top of the box. The student then met the brief of 'personalisation' by adding his name to the side of the design. The print time for this design took six hours however the student hadn't considered the overall size of the design relative to what he wanted to accomplish. Some stationary is able to be stored by the design, however when too many pens or pencils are placed in the design it is unable to cope with the weight. The student is going to redesign this and triple the size of the design to meet the storage needs of it. He is shown a little confidence in Mathematics and practical measurement (Tinkercad includes detailed measurement options) and has a desire to complete this project to the correct scale - this is his second ever project with 3D Printed Design.
For all of the prints on this site and in this series the 'hardward' part of their production remains the same. We are using an Ultimaker 2+ in the classroom, which is now four years old. It has the default settings for printing including the use of an 8mm nozzle to speed up the printing as much as possible (it is possible to have a 2mm nozzle but this of course leads to considerably increased print time). We are using standard PLA (all material and hardware has been sourced in New Zealand from Mindkits)
We will be putting these prints into a specific presentation with tutorial videos explaining the process, including tracking the progression of each of these prints and the development of them from the students perspective.
