Challenge: To revise a print to ensure that it is successful.
Background: We've mentioned a number of times that this years students are two groups those who have experienced using their iPads and Tinkercad in the past year and a second group of students who are working for Tinkercad for the first time.
In this instance this design and print came from a student that 'slipped through the net' that is that it was printed on the assumption that it had been checked, that it looks at first glance to be a successful print however it is going to be used as a teaching point as it needs some adjustment.
The print shown here has some raised areas that are designed to be broken away - their is rafting that is located in two parts of this design. The name 'Hazel' is raised 2-3mm from the base of the design and is not attached to the base of the design. What this means, and can be seen from the following photo is that the letter will detach as it is not permanently attached.
The second area needing adjustment is the base of the design, as the heart that is on the top side of the print is not flat underneath the design. Both these locations of the print contain rafting - which is designed to be broken away.
In essence the student needs to refine the design by firstly ensure that the name part of the badge is directly attached to the base of the design and not 'floating'. Secondly the underside of the design needs to be flattened to ensure it is printed as a single piece.
In this example we removed the rafting under the lettering by taking each of the letters off and then using superglue (the teacher completed this, not the students) to reattach them to the print. The bottom of the print is more problematic as removal of the rafting still means that both the heart and the oval are on the underside - and therefore it is not balanced.
Level of Difficulty: Low - we have talked and provided many examples of this kind of design in the past on how it is an introductory task for students to complete independently as a way to print a design to share that is practical and will have an obvious purpose. There are many examples on this blog which you can search for by using the 'Search this blog' icon from the top right hand corner.
Size: The print as it stands is 135mm by 135mm and has a width of 5mm. This makes the design quite large and would be typical of something such as a large keyring rather than a smaller badge. One of the revisions of this design is potentially the size as it stands it could be described as 'over-sized' at present.
Cost/Price: Using the software associated with Bambu Labs studio the print uses at present 88g of PLA for the print and this had a price point of $2.20.
Timeframe: The print as it stands including the rafting that is not required is six and a half hours.
What we would do differently/Next steps for the students: The print shown left and indeed the entire process and purpose of this print will be to hand it to the student show them how it needs to be refined and adjustments made. The version shown left can be seen to include residue from the superglue from the re-gluing of the letters and also the oval that is above the name could be changed to include an alternative shape of an image.
