Christmas Decorations: Second Run of Prints

The posts in this series followed a first set of prints, detailed below and inspired by the 'Christmas Tree' Print from two days ago.  Since then we have expanded the project to target producing thirty individual prints (for the students in our classroom) and a further thirty prints for a buddy, another student from elsewhere in the classroom.

 Left - Further development of the 'Snowman' idea.   This print shown is prior to the removal of excessive PLA filament.   The student attempted to personalise this by adding the names of her family members on the body of the snowman and placing a soccerball in the middle.   The print has excessive PLA printing on the back, due to its 3D Design (this is going to be detailed in a further, separate print).  This is a 100mm high, 60mm across snowman, which is 10mm deep.  It has a four hour print time which could be significantly reduced.

This print will be reconfigured to remove the cluster of names and lettering on the base of the design.

Left: An original Christmas Tree design, featuring the initials of the student that designed it with their initials featuring prominently in the design.  An attempt was made to have a star at the top of the tree, this was not successful as removal of the rafting also resulted in teh removal of the star.   The student was a nine year old making their first attempt at 3D Printing.   The tree was 80mm high and 60mm acoss at the base.   The design was only 4mm thick which was reflected in the print time of just under two hours.

This is a good basic design for junior students or students who are attempt to print for the first time.
 Left: A snowman inspired design.   The lettering on the base of the Snowman reflected the name of the family that the siblings are part of.  Due to the length of this name and the space available with the Chirstmas message there was considerable issue with the font that was printed.   To remedy this in the re-design the student is going to increase the size of the base and experiment with the lettering.   The design is currently 100mm high, 70mm across and 5mm thick.  Two hours to print.

This design will require reworking relative to the size of the design and the size of the lettering and would be described as medium difficulty.
Left: Designed by a learning support adult in the classroom, these two designs were essentially the same design twice.  In the design the names were prominent and featured a simple star as additional decoration.   The designs were created using Tinkercad and printed with the standart defaults (8mm nozzle/20% infill) on our Ultimaker 2+ Machines.    Two hours to print both decorations, these are not requiring an revision or redesign as task is completed.
Left: A more advanced version of this task.   This is a three dimensional present, with the ribbon used to hang the object.  Of note the width of this print, coming in at 20mm is considerably thicker than the others on this page, which typically are 5mm.   The dimensions of the print are 10mm by 80mm and the print time for this is six hours.   There is minimal 'rafting' with this print.   This is a particularly high level of completion of the task and does not require any improvements or additional detail

Christmas Decorations - Personalised: First Run of Examples

Challenge/Background: This task involved in the students in my classroom producing an original Christmas themed decoration, intended for hanging on the Christmas Tree and then the students concerned locating another student, in another room, who could be from Five years old to Twelve years old and repeating the process.

 Left: One of the first design in this process - features a "hi" instead of a personalised name of the student who created the print, or the person that it was intended as a gift for.  It was 10mm thick with the 'snow-man' design.  This was accessed from the main Tinkercad Interface.   Design time - ten minutes, heigh, 120mm and betwen 50mm and 100mm across.   The only remaing taks was for the student to insert a hole into the hat of the snowman so it could easily be tied to a branch.   Three hour print time on default settings.
 Left: A basic star design.   There were a couple of minor issues with this.   Both the starts to either side of the 'Merry Chirstmas' were not actually on the base of the design, the student in error had them floating on the top (although it is not obvious looking from above).    The design was intended to be personalised so the student was instructed to repeat the process including a personalisation.    The hole that was inserted into the design was to allow easy hanging from the tree.   90mm high by 75mm across with a thickness of 5mm.   Three hour print time on default settings
 Left: A design that needed to be reworked - the original plan for this was to create a face by leaving out features of the design, although this was not clear from the shape that resulted.   There was a word built into the base of the design that was suppossed to read 'Horsey' but because of the size of this it didn't print out to a level that it could be clearly read. Two hour print time on default settings - print was 5mm thick.
 Left - Essentially the same design as shown above, althought this one featured the name of its creator sunk into the design itself, right through to the other side.   The only other aspect of the design was the hole to hang it.  Designed in under three minutes, 80mm across, 70mm high and 5mm thick.    Designed with Tinkercad and printed with default print settings.
Left: Designed by a eight year old with a present design with additional stars, this design was 5mm thick and measured 140mm by 130mm.   It took six hours to print using regular Ultimaker 2+ Default settings.   This was the students concerned first experience with 3D Printing and their first project.
 Left: Using a Christmas Tree as a base, with this student adding additional designs to the base (sunglasses, a moustache, a bow).   The student has produced a considerable number of high quality projects so this was designed in minimal time.   50mm across at the base and 120mm high.   This design took three hours to print with a width of 5mm.
Left: A straight forward design at first glance but for affect the student choose to drop the Christmas Tree's into the base of the design and add thier name.  An addition was then added to the top of the design so it could be hanged.   Design was 90mm across and took two and a half hours to print.   Designed in Tinkercad by a ten year old student.
