3D Printing: Sky Tower Model

Model of Auckland Sky Tower
Challenge/Background: Our School was contacted by a member of the public who wanted to 3D Print a project for their child.  There was a delay in using the publicly available 3D Printers and as a favour they asked for our school to print the project and make it available.
Task: In this instance the design was completed externally and our role was simply to print the design, as it had been designed and completed externally.
Level of Difficulty: Minimum - as a print only.
Issues: None - although in the picture there is a small nick in the front right of the base, this was caused by removal from the print after printing.
Size: 25cm in height, 8cm in width, depth varies according to the design but up to 10cm at the base.
Timeframe: Nineteen hours.
Process: To increase the quality of the print Innofil 3D Print filament was used.  The was designed from an external source so the code was emailed to us.   As a result the design process differed from the regular designs on this site - as it had been created in AutoCad.
Reflection: This was an approach from an external source and it something that would probably not be repeated again, it was a favour to someone who asked rather than an original creation from the students at our school.

3D Printing Logo Designs

Challenge: To re-create a design from a Google drawing created by another student as closely as possible to resemble the original design.
Background: A student at another New Zealand school had designed a logo for the 'International Friendship Day' project.   The school did not have resourcing for 3D Printing so we took the original student design and gave a brief to two of our students to create a 3D version of the design which we then subsequently printed and sent to the student who had designed the original.
Task: As the original design was created in Google Draw it was felt that this should translate well to Tinkercad and some of the shapes that were available from the main screen would be able to reproduce the original design.
Above: designer with design
Level of Difficulty: Easy students were able to reproduce it accurately within a ten minute timeframe as all of the featured shapes were directly created from the Tinkercad dashboard.  The only issue was that some of the shapes were not specific to the relative size in the original and perhaps they could have been more reflective of the original design.
Issues: None - an older filament was used and the machine is in need of a service, there has been a minor issue with some of the filament on the raised surfaces but this is minor and not related to the design of the print.
Size: 20cm by 15cm with a depth of 1cm.
Timeframe: Eighteen hours.
Process: The original in this case was designed by a student in Google Draw.  The teacher was emailed the original design which was then copied and printed off so the students had the original to work with, as with most every other design on this site they used Tinkercad (beta) to complete the project which was then converted to Cura for Ultimaker 2 3D Printing.
Reflection: Students were able to mimic the design and it was a way to allow them to refine some of their skills.  Producing something for another school added to the novelty value of the project.

3D PrintedChristmas Decorations: Tinkercad - Beta

Challenge: 3D Printed Christmas decoration, as mentioned and described in previous posts, a Christmas decoration for a local shop with a theme of the school, thus featuring 'Auroa' instead of the students name.
Background: Students were using the updated 'beta' version of Tinkercad which has an expanded basic shapes and significantly improved lettering options (an option to be able to print a series of letters or sentences - instead of previously having to add each letter individually).
Task: Using the 'beta' version of Tinkercad to design a print, allowing the students to use the new features, with emphasis on the specific challenge.
Level of Difficulty: Easy - while this design potentially looks complex all of the features are in fact part of the new version of Tinkercad and feature from the regular menu.  The student designed this in her first attempt in under three minutes, although she had previous experience with using the original Tinker.  Student is Year 5 - so turning ten.
Issues: The student had a thickness of 5mm with the print to ensure that it ran correctly, which is did, this was probably too thin for the base of the star, which cracked when being removed from the plate.
Size: 20cm in height, 15cm across and a depth of 5mm [which made the base fragile.]
Timeframe: Nine hours.
Process: This was significantly contributed by the new 'beta' version of Tinkercad (which is free).  The design was completed by basic settings and then saved.   This was then loaded into the new version of Cura and then transferred to the printing - Ultimaker 2.
Reflection: If someone was to state that 3D Printing was too technical this is an example of something practical that could be completed in a insignificant timeframe that would produce an eye catching positive example of 3D Printing (in addition there was the intention to Glow-In-the-Dark filament the print for further effect).

Christmas Decorations: Evolving Print Designs

Star with original Tinkercad lettering (hence the differing letters)
Challenge: To create an original 'Christmas' design for a Christmas Tree, suitable to be hung.
Background: As previously stated these designs all evolved from the same project.  While we had three printers running, filament delays meant these were backed up and the project stretched into December, this allowed students to utilise the new beta version of Tinkercad (which is a significant improvement) and also refine their designs based around earlier prints.
Task: To create an original (from scratch) design which predominantly featured the use of the new objects and lettering from the beta version of Tinkercad.'  The original idea was for a personalised one, then the School was requested to make a series of prints for a Christmas Tree at a local shop - however students involved in the process did not want their prints in general to go to the shop so they used them for their own trees despite featuring the name of the school!
Level of Difficulty: Easy - some of the students involved modified prints and designs that were used as part of the 'Cookie Cutter' projects with subtle changes.  The students creating from scratch were able to create the key required parts from the basic set up.
Issues: The student decided to individually create the letters using the old version of Tinkercad, therefore they were slightly different sizes and the second 'a' was noticeably smaller than the others, however student was more than happy with this.   The box was introduced as a base for the printing of the letters.
Size: 20cm from tip to tip and 20cm across, depth of 5mm.
Timeframe: Eight hours. (Ultimaker 2+ with 4mm nozzle)
Process: The original design was created using a star shape that was located as a stencil GIF as part of the 'Cookie Cutter' project.   The student wanted to use a base design for a star for the top of the tree and thus took the original star design and simply added the 'Auroa' block and lettering to meet the criteria desired for the Christmas decoration.  The new version of Tinkercad was not used as the student preferred using the older version which he was familiar with (see note about the lettering).   Cura was used as with most prints on this site and then the print was downloaded.
Reflection: the student himself was extremely happy with the print but this was essentially just a small modification of a previous project, and while he was happy with the results he could have had more variation with it.  As a project to capture attention for a display piece its some seasonal value and the potential is there for considerable personalisation of the ornament.

Christmas Decorations 3D Glow-in-the-Dark

Bottle design, sans cork
Challenge: to create a decoration for a Christmas Tree designed (from scratch) by students suitable for hanging on a Christmas Tree.
Background: This is a further development of the 'Christmas Decorations' post from earlier in this blog.  Initial designs included run of the mill decorations that were not completely original and involved converting GIF pictures - this design was from scratch, included in it was an innovation - the student created a 'cork' or insert for the top, which would allow this to be hung.
Task: The student was wanting something extra for his first print and thus created the lid/cork which worked as an insert.
Level of Difficulty - Medium - the student wanted to add the extra by having the 'cork' which needed a separate part and able to be inserted into the top thus allowing it to be potentially hung.
Issues: the print was completed with glow-in-the-dark filament, it seems a little flaky compared to the regular and not as smooth.  The cork/lid fitted perfectly at the second attempt, as it needed to be resized from the draft print - however it fitted perfect and was snug which created the avenue for it being hung from a tree (its going to take the place of a star on a family tree!)
the cork/lid with rafting
Size: 11cm in height, 5cm across and a depth of 5mm for the base.  The letters had the deliberate effect of being different sizes with the intention of creating a 'step' look.
Timeframe: Six hours - on a regular print.
Process: Tinkercad (Beta) design from scratch, converted to Cura (new version) and then printed on a regular Ultimaker 2.
Reflection: The Y5 student (ten year old) created the design himself and was able to show good attention to detail and creativity by adding the cork/lid.  The student concerned was thrilled with the result which completed the brief but included an innovation.

Product Evolution: Christmas Label

This series of prints were all produced by the same student, whose designs were the first time that he had used Tinkercad.   It was his first design using Tinkercad and the first time that he had created a 3D Print.  He is a Y5 student meaning his age is ten years old.

The original design and print - student brief was for a label suitable for a present for Christmas.  As it was a prototype and the students first print he opted for a simple block design with 'Mila' (the name of his cousin, who the gift was for) written across the top.   He created it from scratch in Tinkercad, with a three hour print (rafting has not been removed and is visible at the base of the print).   Design was 4.5cm across and high to a depth of 2.5cm - print time for this project: three hours. 
 Having created the first print he decided to refine the print on the basis of being able to attach it to the present, thus he created a hole in the top (earning the nickname of the 'toast' in reference to its likeness to a slice of bread).   He also sunk the letter for the name and added a geometric shape in the bottom right hand corner.  Width of 6cm, height of 5cm and depth of 5mm.  This was also a three hour print, however it was printed on an Ultimaker 2+ (the previous print was printed on an Ultimaker 2 regular).

In the third version of the project print the student had started to experiment with added additional shapes to the design.  The holes that were printed at the bottom were intended to 'hang' to design, which meant it was impractical work as a label.   The design features of all of these designs were created from using the geometric shapes design feature of Tinkercad.  This third version was also printed on the Ultimaker 2+, without any rafting.  Width of 6.5cm, height of 5cm and depth again of 5mm.
This project was again with a print time of three hours.

This was the final run of the project - the student made the decision to print the project using Glow-In-The-Dark filament.  The intended recipient is a cousin is four years old so the student felt that by printing with that filament would add something to the project.    The print was completed on the Ultimaker 2 (note the comparison between this and the last two prints in the sequence with the 2+) an exclamation mark was missing following the '1'.   The depth of the print was 2cm - it therefore gave somewhat of a 'block' effect rather than a label, however the student himself desired to have this effect as he thought it would work as a stand alone present given its display possibilities.   The two holes that were printed into the design were of different sizes in the form of an experiment.   10cm wide by 7cm high by 2cm deep.   This print took nine hours to complete.

3D Printed: Lawn Mower

Student designed: Lawn Mower print - 18 hours
Challenge: To produce a working model of a Lawn Mower.
Background: A presenter who had heard of the 3D reputation of our school wanted to produce a series of props for presentations, the pieces that he was looking for needed to represent actual objects that people were familiar with.   The props needed to be as life-like as possible.
Task: Student created a representation of a lawn mower using Tinkercad from scratch.
Level of Difficulty: High - the student was creating not an original piece but a copy of a common everyday item.  It had to be recognisable and plausible.
Issues: Rafting caused the wheel to be removed when the rafting was removed.  The filament used was not standard filament (see below) and as a consequence is more difficult to remove.
Size: 18cm by 10cm by 15cm
Timeframe: Regular print settings - eighteen hours.
Process: The student was using the Beta Version of Tinkercad, which had just been released prior to the project being completed.  The print was completed using a different filament from previous prints.  Previously we had used a cheaper 'regular' filament - the Innofil was approximately 50% more expensive but it was clearly visible in the quality of the final printed version.  After consulting with the classroom teacher involved this filament would be preferred for 'show' or demonstration pieces.  The student designed the print from scratch including all aspects of the design.
Reflection: The student responsible for this design has shown talent and creation right from some of his first projects when he was Y5.  He is currently a Y6 student, who is ten years old.  He is able to individually create designs with this detail using free software.
