3D Printed Exemplars: Bringing Up Standards 2

 

This is the companion post to a post on this blog on October 6th.  In this post we spoke about iPad stands that needed to have some finishing where the top of the designs had to be replaced or reworked.

In this example (left) we had a motorbike design which needed to be replaced due to its lack of finishing.   The student who designed this iPad decided to replace it with a font from a game that the student liked.  

The print was located online and had been created and made available on a site that allows material to be 

The font/heading was 90mm across, 30mm wide and 30mm high for the main point of the lettering.   The print was completed on the Bambu H2D Printer and took one hour to complete.  It was decided for the purpose of contrast to complete the print in gold, although there is a question of the spray painting of the design.

A common adhesive glue was used to bind the extra font to the top of the print.

In the second example we had a series of flowers across the top of the iPad stand.  Three of the four flowers didn't survive the removal of the small amount of rafting on the top.

The replacement piece was the bird shown left which was designed in Tinkercad.   The student wanted to create a duck and the dimensions of the design reflected that.   The bird was 70mm long, 40mm across and 20mm high (the body) the head was another 20mm high.

The duck took thirty minutes to print on the Bambu H2D.

The student should have considered the based of the duck which would have been easier to attach to the top of the iPad stand.    

Personalising Bookmarks/Upscaling Designs

 Please Note: The activity in the classroom for 2021 in New Zealand, where this classroom is based has just begun again.  There has been a slight change in direction for this classroom teacher over the past twleve months with a significant classroom project devoted to sound lures for pest control.   This is located at soundluresnz.blogspot.com.    The classroom work has continued in the 'regular' classroom but some of the prints that have been completed have been repeats of previous years work, rather than blog about this again a decision was made to wait until new and different ideas we being worked upon.

Challenge: Student had produced 3D Printed basic designs and wanted to extend themselves further while still maintaining a small scale project to engage them at the start of the year.

Background: The student here had been printing projects on and off for the past two years and had a good grasp of concepts and ideas.   Getting them to engage was not an issue but likewise the task needed to be slightly more advanced than usual but still mean that the print was manageable for the student and could realistically result in large scale printing (with thirty students in the classroom).    The student in this case had an interest in literacy and books.   The student was able to source a book that had been previously created and was available as a free download via Tinkercad.   From here the student was challenged to adapt the book to reflect themselves and add some layers to it.   The ten year old worked independently and put their name on the cover, put the hole that is visible through the entire book and added their initials into the spine of the book.   The student also spent time thinking about the design of the book when it was completed and could be painted, oil based paints, thinking about gold lettering and the sort of book that could be produced prior to the printing press.   While it was an involved and lengthy process it elavated the process and the print.

Degree of Difficulty: Low - this was more about the process and the final produce than it was the design, the student was able to execute the design and it was the additional aspects that kept them motivated and working on the project.

Size: The print measured 60mm wide, 80mm high and was 20mm tall.  Given the lettering etc it was probably about right for the size of the project.

Timeframe: Three and a half hours - but please note we are using six year old Ultimaker 2+s to complete the projects that we have been working on.

What we would do differently: Nothing at this stage the student has got particular ideas about how this might look and the final ideas about the print might not meet expectations but the design process has done.

3D Printed Student Bag Hook V2.0

Challenge: Student wanted to design a personalised bag hook, that would be functional and personalised.   This design was originally created with a 'cone' shape, testing revealed that the bag would simply slide off making the design not work.   This design was created to adjust and solve this problem.
Background: Student was showing creative design instincts having previously been responsible for the jewellery box design amongst others.   The first design had failed, this was an attempt at an improvement to resolve the issue.

Level of Difficulty: Medium.   The design premise is basic, however there has already been a considerable reworking of the original design based around problem solving.  There is another area that requires considerable redesign - as viewed in the photograph above you can clearly see that the screw holes in the base of the plate are 2cm across.  This clearly would not work with anything other than extremely heavy and large bolts, which would not suit the purpose of this design.   
Timeframe: Seven hours - this design should require further refinementm the hook itself at present is 6cm from the base, the purpose could be achieved by having something half this distance. 
Size: The dimensions of the print are a depth of 5mm.   8cm wide, 12cm high.   As mentioned the hook comes out 6cm from the base.   The rectangle is 3.5cm by 3cm with a width of 2mm.   The base plate has a depth of 5mm.  Strength testing is required to see what weights of school bags could be held up and what the timeframe would be.
What we would do differently: The task needs to undergo strength test see what weight of school bag could be held and for what length of time.   The holes for the two screws to attatch to the wall need to be resized and redesigned. 
Next Steps for the Students: To considerably redesign the mounts for the wall and to possibly have a third screw hole at the bottom of the design.   The size of these needs to be refined.   There is a clear need for significant strength testing based on the size of the design, the weight of school bag that it can safely have (relative to the wall) and the length of time it will hold it for, which would be an amazing Mathematics lesson.

3D Print School: Y3/4 Bookmarks

One of the challenges for 3D Printing is allowing younger students sometimes access to and use of the machines.   Our School has targeted this group of students with a Junior STEM program, with the intention of giving the students access to 3D Printing in the Classroom.  The initial design for this project, created by the School Principal, Heath Chittenden, was students creating a book mark suitable for reading.   Students were given a Tinkercad logon which they used to refine their design on the basis of circles - they picked up the process quickly.  Extension for the students came from a student who created a ring.

Learning Challenge: To design and create a 3D Printed Bookmark suitable for use with a book.  Students to use a basic design (featuring the circles) and then added their individual touches.
Background: Using the 3D Printers with students in the Junior School.  Junior School in New Zealand equates to students between the ages of 5 and 9 years old, although this class were 8 and 9 year old children.  Lessons took place for an hour once a week.
Task: Students had to design, manufacture and make a working bookmark.
Level of Difficulty: Low - a template was used for the basic design for the students.

Issues: student originally had some feet an antenna that while they added some detail to the creature tended to be flimsy and easily broke off or had to be removed after the final print.  As an added detail the filament used to print the bookmarks was glow-in-the-dark filament.
Timeframe: 3-4 hours on basic print settings.
Size: As seen from the shot 20cm in length and a depth of two to three centimetres

Process: Template designed in Tinkercad, shared with students.  Students then edited the design, and added additional features.   Converted to Cura and printed on the Schools Ultimaker 2 3D Printer.

Student Created Trophy for Sports

Students original Tinkercad Design

Learning Challenge: This student independently created and designed this project, having had previous experience during the Auroa Primary School Technology 3D Printing School program. They were a Hockey student who wanted to remember the season with a trophy.
Background: The student having had experience with the machines and the program wanted to gain additional credits towards the school rewards program and also recognise the (field) Hockey season which had been completed.
Task: The student generated the design in their own time using Tinkercad without teacher input.

Students design printing on the Ultimaker 2

Level of Difficulty: Moderate - the design required some modification (see below) however it was not significant and was completed on the initial print run successfully.
Issues: the original design came with a stick on the ground, sans the hockey ball, the ball was added to give stability to the design as the stick by itself was lacking in support.   The design of the ball was intended to stabilise design and not necessarily based around scale of an actual Hockey Ball.  The original Tinkercad design by the student featured two designs at the student wanted two copies.
Timeframe: The student came completed with the full design having done so in her own time.  Forty hours to print.
Size: Base 20cm, depth 15cm, height 25cm.  (approx.).
Process: Designed straight into Tinkercad.   Downloaded in the Cura, the Ultimaker 2 Free Software.  As per the rest of the material on this site it was created (printed using an Ultimaker 2)

Student Perspective on 3D Printed Speakers

This is a student created video and shows the process (entire process) involved in the creation of the Auroa Primary School Technology DPE Program Speakers. Theses speakers feature speaker covers that have been 3D Printed by the students, feet and handles designed and printed by the students. The student explains and shows her work from the entire process. You can view previous details of the project, including the 3D Printed aspects of it below:

Technology Program at Auroa Primary School

This video produced for Auroa Primary School describes the Schools' DPE (Technology) Program.  It details the teaching process in the four key areas of DPE (Technology) for the students, 3D Printing being one of these.  It is a detailed description from the teaching staff and students of the program and how it is taught.   Additional details have been hyperlinked.

3D Printers: Speaker Technology Project

These photos represent the Technology created by students at Auroa Primary School during the students technology.

The students as noted have a range of subjects, the speaker boxes were created as part of the Woodwork technology cycle.  All additional external pieces for the speakers were created using Tinkercad and Printed using Ultimaker 2 3D Printers.

Students designed their own speakers and thus the handles were all custom made and designed for the individual speakers.   Two covers were created for each speaker and they were also 3D Printed.  The feet for the speaker were also designed and created by the students.

For those of you interested the speakers are two 15 Watt Channel speakers (total power 30 Watts) and they were controlled by an iPad/iPod/iPhone.  You can find additional information about the speakers from Tim@Mindkits.

3D Printing: Student Work at Auroa Primary School

Auroa Primary School for 2015 created a modern program for Technology for students - a series of lessons were created for Robotics, E-Textiles, Woodwork and 3D Printing.  The School website has details of the program that the students are involved in, with examples of each.   Each of the students have had the opportunity to work on Friday from 9am to 2:00pm for five week blocks. The final activity for the students was a free design activity allowing students to create an original piece of 3D Printing Work.

Original Design from student in Tinkercad

The project was designed following a creation process by the students, a creation of the project using Tinkercad and then a trial and creation of a Prototype.   In the link above you can see examples of some of the original work and ideas created by the students.  

Golf Egg Cup Print

Students managed the entire process themselves - in this example on this page the student concerned had an interest in Golf.  The student created a model of an Egg Cup with a Golf Theme, created the model digitally using Tinkercad and then created a draft print.  The original print was not successful as the cup was not balanced enough to hold a regular hard boiled egg.  The student redesigned the cup portion of the cup ensuring the base was larger and was then able to complete a successful print.   The original print was a draft setting.

The detail was added to include the indentation the grass design on the base and the Tee/Cup design.    The student was able to complete this on the second print.  The time allocation of print was eight hours on the 'Fast Print Setting'.

58m of Filament and 39 Hours...

Learning Challenge: As part of the student projects for Technology for Y7/Y8 students at Auroa Primary School in New Zealand students had a design option for the final block of time in class.  Students had to plan, create manufacture a free design option - the student in this case choose to create a Kitchen Utility Holder, however the dimensions of the object, which were approximately 30cm cubed meant this was the single biggest print to date.

Background:  Auroa Primary School has put online its digital learning for the use of 3D Printers.  You can view that by clicking on the link here.  As mentioned above this design came in the final part of the 3D Print Design Process, however it was significant that this was the largest single print attempted thus far.

Task: A free design task for students, however it was not an 'open' task as students had to design, create and follow a process.

Level of Difficulty: Moderate - the design was the creation of the students.  In this case the name of the student was cut into the design.

Issues: The inserts into some of the utility holder were vertical, this meant that the primary one worked well, however the angle on the other ones should have been tested with various kitchen items to ensure that they would work with a variety of items.   Wooden spoons for instance would sit well in the main well, however the angle of the outside holders had meant that would not work.

Timeframe: This print took 39 hours to complete on a regular setting.  It wasn't clear prior to the print whether or not it would be achievable.  Given the time that was projected being so long the concern was that the print would not smoothly print at some point early in the piece preventing the print from completing.  As it turned out this was unfounded.  It printed perfectly.

Size: the completed project was 30cm wide, 30cm long and 25cm high.   The print used 58m of filament.

Process: Paper design, converted and created in Tinkercad.  Converted from Tinkercad into Cura and then downloaded for 3D Printing.   The student had not apparently intended the design to be as big as it was.

Further Reading: Auroa Primary School's Technology Program is now available online.  It includes the entire teaching process, details about student projects and examples.

3D Print School: Building Assignment - Stylus Holder

Completed Design with Stylus inserted

Learning Challenge: As part of the technology program the Senior (Y7/8) students of Auroa Primary School have technology once a week from 9am until 1pm. The focus for the 3D Print Group has been to design a holder for a stylus, suitable for the students to use in the classroom.


Background: Students are in groups/classes of ten. The first task for the seniors was to build a stylus holder.   This was nearly the entire groups first attempt at constructing and designing something with Tinkercad/3D Printing.

Stylus inserted into largest cone shape in visible hole

Task: The design had to be practical and work in a sense that the items that the students created had to be useable.

Level of Difficulty: Moderate. Students had free range with the designs, size varied considerably. The biggest challenge was the size of the hole for the insertion of a stylus.

Issues: The design of building a holder into the actual object caused some difficulty. Most students had not anticipated either the depth of the hole required to be successful, or had the hexagonal shape correctly copied. Initial designs had the name of the students extending from the shape, more effect was had in the repeat prints where the students opted to put their names cut into the holders.

Student name built into the design

Details: As part of the Auroa Primary School Technology Program the first prints came from the first lesson. The Y7/8 students had not trouble coming quickly to grips with Tinkercad. Further details of these projects and examples will be posted on the school website and this post will be updated then. 

Timeframe: Design to construction including detailed planning took an entire session. Prints were run on the lowest quality setting due to the number of prints, however these were more than adequate. 

Modified slightly to hold pen.

Size: Varied in design. A selection of photographs of various projects have been included in this post, the Stylus concerned was a regular stylus used in the classroom to assist their digital learning. 

Process: Paper design, converted to Tinkercad then downloaded for 3D Printing. As per everything else on this site to date was printed on an Ultimaker 2 Using Cura.

Further Reading: Details of the individual student projects will be posted on the school website and this post will be subsequently updated.

Home Enhancement: Making Life Better

Learning Challenge: Using 3D Printer to Make Life Easier

Background: One student in class sister had a medical condition which limits her motor skills, cerebral palsy.  As a result she had trouble operating her iPad because she couldn't tilt it when it was lying flat on the desk in front of her.   Her brother thought that the 3D Printer would be ideal in designing and making a tilt to allow her to use her iPad with easier access.

Task: Help someone with difficulty by 3D Printing.

Level of Difficulty: In this case the student came up with the idea, concept and all other aspects of the production.  His sisters condition allowed him to identify the need and he was successful with the second print of achieving what he wanted.  Low.

Issues: The tilt was constructed with a specific iPad cover in mind.  A potential extension was to further develop a clip however as the first run was so successful this was not required.   If his sister had a different cover for her iPad then the task would have been considerably more difficult.

Details: Completed by a Y8 (12 year old student).   The print was successful on the first attempt.  The design on Tinkercad was able to be produced in under five minutes.

Timeframe: Forty minute print time.

Size: 15cm by 10cm.

Problem Solving: As mentioned the iPad case and the design of the tilt complimented each other a obvious further extension was that the student design and create an original stand for use with the tilt.

3D Printing: Students Design Portfolio

This is a sample of a student from Auroa Primary Schools Full 3D Printing Digital Portfolio. For the school wide reward program for Innovation and Design the students were required to complete five projects (this student completed four in the allocated time, was unable to complete the Key Holder due to faulty design that would not print). Each design was completed on paper, converted to Tinkercad and then a test run was completed. A second print run was then made on the basis of the success or otherwise of the print. The included screen shots an scans are work from a Y8/12 Year old student.
