3D Printed Market Day: Final Product Octopus

 

This design has undergone a series of developments and refinements and is now being completed ready for the 2025 School Market Day.

We have previously spent time explaining the design process - the refinement process and how this project has evolved with the students Tinkercad designs.

The design is being designed into three sizes and all of these will have small variations in the details that are added to the design.  In this instance figure has a top hot on its head.  

One of the excellent aspects of using the Bambu Lab software to process the .stl file is that it clearly shows the details that the students need to make decisions about their business and recently we have started discussing profit and loss.

The print time for the this print on the Bambu H2D is just over two and a half hours.   42g of PLA filament was used to create this print.   For a regular roll of PLA we could complete 23 of these prints.  We would need to make a recoup of $1.70 NZD from each of these prints to meet the students printing costs (the listed price from Bambu is 0.96).    For the purpose of the profit and loss for the students the price point that they need to set for the large Octopus.

As printed on the Bambu H2D there is absolutely minimum rafting that is associated with this print - the linking between the tentacles as shown is how it was removed from the plate, without the need for removal of any waste plastic.

The dimensions of this print has the individual tentacles at 60mm.   The base of the main body is 50mm across and 50mm high.   

The final decision that the students need to consider is the different PLA that the prints are completed with.   As the students are targeting a design that they want to float the design in water.
