3D Printed Ant: Advanced Version

 

Challenge: Create a unique and detailed insect using Tinkercad to define and detail the features.

Background: Its been detailed on this blog for several weeks about the insect project which came from a focus on our 20206 Pet Day Art Display.

As part of the art display we've got a small 3D Print to go back and put on display with our art projects.   The challenge is based around shared literacy tasks - last term we researched, investigated and wrote about insects and analysed their characteristics and features.  This design was influenced by some of the earlier ants in the series that had the form and character correct but were lacking somewhat in some of the more detailed features.

When you view the face of the design you can see the student has opted for antenna, eyes and also the mouth has been based around viewing close up and magnification of various ants.   This student also went further making this a 'fire ant' and was able to adapt the colour palette on Tinkercad to do so.

There was a technical error that occurred with the printing of this design, one we are going to investigate further.  The student designed this as per our usual process - and one of the legs, at the back left, did not print successfully on the Bambu H2D - although it did on the P1S.    We believe based on a quick investigation that the speed of the H2D in this instance was too quick for the design, and the shaking and the movement of the printing process caused the fault in the process - this is the potentially the case as the smaller, cheaper machine was able to print the design successfully without any error.

The student who designed this print spent time to ensure the legs were shaped and had segmented detail on them.    There are grooves in the mouth of the ant and additional small details throughout the design.

Resources used to complete this print: iPad, Tinkercad App, Bambu H2D, Bambu Blue PLA

Size: The print at present is 80mm long, is 40mm from the base of the feet to the stop of the segments.   The biggest body segment is 30mm by 30mm and the middle is 20mm by 20mm.

Cost: The print uses 67g of PLA to complete the print which included rafting.   This gave the print a price point of forty one cents to complete.

Timeframe: To complete the print the Bambu H2D was running for one hour and eight minutes.  A switch to a Bambu P1S would not significantly alter the timeframe.

What we would do differently/Next steps for the students: It is our clear intention to print this on the slower, smaller printer as we believe the print will be successful (we could also slow down the H2D).  The intention was to print a fire ant with a red base obviously the PLA used was red although potentially we could have made a two coloured print using the dual nozzles of the machines.   The legs also at present have the same pose on both sides the student has the ability and the skill to pose these differently and produce a design that is reflective of a more natural post.   As noted as well the width of both the legs and the antenna reflect the students desire to create a robust print that would survive handling.

This entire project was undertaken and completed (independently) by a nine year old cohort two student.
