In commemorating the Singapore national day on 9th August, we have made several mementos using our 3D printing as well as Arduino programming skills. The combined skill-set enables us to design and fabricate items tailored to our needs. Each of these designs is unique to us and cannot be found elsewhere. There is the beauty of such skills.
The design looks simple exteriorly. However, it requires some level of skills set. For example, the legs of the table lamp are slanted. It is definitely another level of techniques compare to another design that have vertical legs.
Secondly, the tolerance between the contour of the image the image and the background as well as background and the body have to sufficiently fitted. It is a show of good craftsmanship. It must allow lights to pass through to create some kind of demarcation line between the object and the background. The background plate and the body have to be relatively tight-fitted, but still does not require any tools to fit them so that the item can be inverted without the plate dropping off.
Thirdly, the two-colour set of red and white on the body means that we have to either 3D-print the object on a 3D printer that allows two-colour printing or to print the bottom half and the upper half separately. In order for the upper half to be aligned to the lower half, we need some kind of alignment tool or device embedded on the two halves in order to maintain this alignment. In so doing, we need to incorporate the alignment provisions in the designs but hidden from outside. This means that we need to combine the vertical wall and slanted wall during the design of the body.
To enable the flexibility to change the design as often as we need, the top plate is 3D printed separately from the body. This will allow us to change the design of the top price as often as we need, minimising our designs and 3D printing time.
Other than the 3D printing, we also include Arduino programming in the features. With the combination of colour lights, the final object looks more lively. We have tried both the single and multiple analogue as well as digital (or addressable) RGB LEDs for this project.
