3D Printed Art Lettering for Market Day Project

Above: the 20mm 'STAY' lettering

Challenge: A student project team are working on running a classroom business for a market day want to utilise the 3D Printer to produce lettering for words and phrases that could be then combined with wooden blocks/lettering to produce a finished piece of art.
Background: The students of the school have a project this term for them to run a business.  A number of the students groups are producing art based projects.   One group was interested in looking at producing signage on wooden blocks of themes or sayings.   To produce the lettering part of the art project the students wanted to utilise the 3D Printer to produce the lettering and then mount it onto the wood.    This involved the students selecting a design that they were happy with and producing a font that reflected a design and style and that could be combined with the wood.  For the wood the students selected a wood pallet and used the school Woodwork room to cut the wood into blocks.    The students were dealing with a block that was

50mm high and 500mm across.    They had the potential to shorten the length of the block dependant of the length of the words or phrase.    The students were able to trial print the lettering and then work out the dimensions of the wood that they wanted to use.   The students started with a basic design and font, worked out the dimensions and then develop an idea of concepts related to that.  They also identified key areas to move forward successfully with the product - that they would need a Wood Glue to mount the lettering onto the wood and also for the wood to be stained to help enhance the look of the lettering.   The colour of the PLA will be contrasted with the staining of the wood.   Once completed the price of the design was minimum - the PLA for the plastic for the 3D Printing and the Wood Glue and stain were the only expenses that the group needed to account for.   The students also are keen to experiment with different PLA relative to the stained wood and look into using different filaments with the potential for the use of glow-in-the-dark PLA.

#3DPrintEdu - 120mm x 60mm

Level of Difficulty: Low - the single challenge for the production of the art block and combination with the 3D Printing.    The font selection from Tinkercad is significant the only aspect that the students needed to determine was the size of the font that they were printing.
Size: As shown in the photograph the 'Stay' font measured 20mm high and was grouped (clustered) as 60mm across.   This font was designed to be 5mm deep.   The 'Live' font shown in photograph was 30mm high, 70mm across and 10mm deep.    The #3DPrintEDU chat font was 120mm across groupd and 60mm high.   The depth of the print was 5mm.    The largest print that was run in this run was the 'LAUGH' print and font - this font was larger that the block of wood that it was intended for.    This measured 130mm wide and 70mm high.  It had a depth of 10mm.

Above: the final trial design

Timeframe: As this was a series of prints the lettering itself varied significantly.   In the four featured prints here the 'Stay' print took thirty minutes.   The 'Live' print was forty five minutes.   The '#3DPrintEDU' print took one hour.    'Laugh' was the biggest print of the series (as noted it is essentially oversized) which took two and half hours.     This would vary depending on the size of the block that the students would anticipate using - that had a measurement of 50mm high (but again could be cut to size). 
What we would do differently: The students have a lot of potential development to come relative to the size of the wood that they had produced and cut.    The colour of the wood that is produced from the staining will influence the final design and PLA choices by the students.   The students are also looking for a 'wow' factor and want to experiment with different PLA options and choices including Glow-In-the-Dark filament.

3D Printed Student Lip Balm Holder

Heart Shaped Box viewd from above.

Challenge: For student to produce a functional lip balm holder, with a working lid.  The students who created this project were nine years old (working at Y4/5 level in New Zealand)
Background: This is the second featured print from the series previously described here.  The idea was for the student to produce a product that could be marketed to the general public and this is a test pot, featuring the lip balm with the logo of the business allowing people to sample the produce.

Lid wtih rafting present.

Level of Difficulty: Medium - although the print is not significant in size the design featured a working lid that was required to be printed seperately and work together in conjunction with the base.  This required a drop down lid with an insert/lip that would allow it to sit ontop of the base.  The print was successfully completed with the base the first time.  The lid when the 'rafting' was removed (by the teacher with pliers) an adjustment needed to be made with the insert as it required a further layer of removal, this was completed by the parent of the student who designed it, in his workshop at home.  (Had this not been possible we would have simply reprinted the lid with an decreased 'lip' insert which would have been in the one and a half hour to two hour timeframe).
Timeframe: Eight hours - 8mm nozzle size, with standard PLA.   The process was completed by a Tinkercad design followed by a conversion to Cura (the new updated version) and then printed.

Completed print with lid

Size: Both designs were printed 1cm high, a height of 9cm and 6cm across.  The idea was that they would sit in the hand of the person holding them.
What we would do differently: The students have produced something that has solved the brief in a really positive experience for the students.  They were able to design and create an original Tinkercad project which then translated extremely well into a 3D Print.  It was the students first experience with 3D Printing and has allowed an original eye catching prop to be completed for their presentation.

3D Printed Student Business Project Containers

Container and lid before rafting removed

Challenge: For student to create and print a unique personalised container that was suitable for the holding or storage of liquid (conditioner).
Background:   All of our students have a significant showcase coming up.  As part of this the students in the classroom next door are producing a range of products that are unique which they create which they would like to brand.  3D Printing allows them to engineer and design their own products (using Tinkercad) and then create them.  The students in this case are nine and ten year old students.

Two lids, reprint on the right

Level of Difficulty: Medium.  The students were designing for the first time and were able to have students assist the process who had 3D Printing experience.   There had to be a re-print of the lid as, as the drop down aspect of the first print did not work.  It did fit however the fit was extremely tight and wouldn't have been easily removed.  The student was made aware of this issue and created a second lid, which was a seperate print, the internal aspect of which fitted much better for the purpose of the print.  
Timefame: Ten hours for both the base and the lid in this case.  The second reprint of the lid, when it was just produced on its own took two hours.
Size: Ten centimetres for the height of the container, 6cm across.
What we would do differently: Very little.  The students concerned meet the brief that they had created and were excited with the results.   It was a successful print, allowed for a degree of individualism and created a unique print for the student.  The student had not had significant previous experience using Tinkercad but was able to confidently produce the print.  (The teacher had to remove the rafting using pliers on this occassion).
