3D Printed Bottle - Exemplar

 

Challenge: For a student to create a unique and individualised project.

Background: As detailed in a previous AR/VR and design task was the challenge for students to create something unique - this meets the criteria of printing an outstanding design and this student wanted to make a copy of a bottle.

He based his design on a bottle that is available as a design from the main Tinkercad interface.   He wanted to replicate the design using the different shapes and tools that are freely available and did so using his iPad and the Tinkercad App.

There was a considerable amount of design associated with the creation - and he wanted to ensure that it was a viable print, which was completed once he had shown that he had the dimensions mastered (using the 'measure' tool) and could justify how it might be used (which of course is helped by the fact that the PLA is waterproof and when printed as a solid shape is water tight.    The students next step is that he wants to develop his skills further and work on a lid, with thread that can be used to screw and tighten on to the bottle.

Level of Difficulty: High - while this is a eight year old he has spent considerable time applying his design skills to create this bottle and has done so from scratch constantly revising, working on and developing his project over several days (which he has done in his own time).   The 'unlocking' or successful completion of the lid will prove challenging but the student is determined to complete it.

Size: This is significant print with significant dimensions.   It currently measures 210mm high and is essentially 70mm wide.  It is narrower at the point of the lid where it is 30mm across.   

Cost/Price: Using the Bambu studios information relating to this print we can determine that to print this unit, including the 'rafting', the support PLA that it took 200g of filament.   This is a significant amount.   The cost associated with this print is $4.91.   This is considered something of a one one based on these dimensions.

Timeframe: The print took considerable time to complete being printed over five and a half hours.   It was completed on the Bambu H2D and we would not consider completing it on any of other machines due to the finish and detail required.

What we would do differently/next steps for the students: 

We followed through with the printing of this project based on the creation by the student and their input outside of the classroom process.   The print dimensions, cost price etc means that this is not feasible for a classroom project (although of course could potentially be in the right circumstances).   The opportunity to personalise the print was clearly there as was the potential to use it in conjunction with something like the Roland Versa Sign Maker machine.

The lid is potentially the most challenging part of the entire process, identifying and successfully executing this is very challenging but the student appears to be relishing the opportunity presented by the design challenge.

Junior Cohort Challenge - Bottle

 

We are encouraging students as much as possible to come up with original designs and creations, thinking about objects and shapes that students can create and detail using programs - in this case Tinkercad is our design tool.

Students are using Tinkercad with their iPad to create designs such as this.   This was created by a cohort two student, that is student who has used Tinkercad previously last year and this year we are looking at projects to extend their design skills.

While there is a range of objects that can be selected to design one of the best items for honing the design skills of the students (again as we have pointed out numerous times are seven and eight year olds).   

The concept of the design and the production process are some of the most important process.

The original Tinkecad main interface item is the bottle shown left of the pair, the original being shown above.   The main difference between the two designs at this early stage (as the student has had precisely one block of time in class being able to design this) is that the student has not hollowed out their design by using the 'hole' tool accessible from the main page.

This is something that the student will have the skill to complete independently and should be able to succeed with shortly.

The student also was able to look at using the final stage of the testing, which was to use the AR/VR function that is present in Tinkercad to project both of the bottles into different locations in the classroom.

In the example shown left the project virtually of the objects allows the students to compare how they look in a real settings, what they might need to do to adapt the design and how the could compare to each other.   The student also put a 'real' bottle into the mix as well but decided against the photograph as they had labels and stickers on them which meant it was very visual to see what was the 'real' bottle.

The students next step is to refine the design again so that both of the designs are closer to each other with their dimensions so the two are identical.
