Week 9: Physical Models

Physical models of my Deathly Hallows design using different materials and fabrication tools...

Object 1: Deathly Hallows Sign

Software: Adobe Illustrator 

Materials: Acrylic

Fabrication Tools: Laser Cutter

Pieces

Construction.
The slotting of these two pieces is to large so they do not fit together nicely without falling apart. In an attempt to see how far the slot would open if i made it to small and it needed to flex. I snapped the acrylic, hence the masking tape

It creates quite a wonderful shadow 

LED light shone through Deathly hallows in the dark

Object 2: Criss-Cross Base

Software: Autodesk Inventor, UP, Netfab

Materials: Plastic 

Fabrication Tools: 3D Printer

3D printed base for sign to slot into.
I had trouble with the scaling for this model. It was created in Inventor. When the STL was loaded into the 3D printer software it came up 10x smaller than it should've been. I had to back to Inventor and multiply all my measurements by ten and re-save. I reloaded the new model and it came up the size it was supposed to be

However the cylinder in the middle is supposed to house the battery below the level the Deathly Hallows sits, But it doesn't. There is a very minuscule offset but not one big enough. I think I may have forgotten to 10x the measurement for the extrusion of the cylinder.

The connection of Hallows and Criss-Cross base...

Combined.

The slotting in the base is to thick for the acrylic. I did make it bigger than it needed to be to ensure it would fit but I made it too big

Object 3: Sphere base

Software: Autodesk Inventor, UP, Netfab

Materials: Plastic 

Fabrication tools: 3D Printer

Criss cross slots cut into sphere for Hallows to slot into 

Chopped of the bottom of the sphere so it has a stable base to stand on

Slot in centre for battery to sit in

LED slots its prongs onto the batter. battery slot is not wide enough for LED prongs to slot into cleanly. LED gets stuck in slot and requires force to remove. This is not alright because LED slotting onto battery is the switch. 

Translucent white plastic glows with LED at the centre. 

Translucence of the white/clear plastic shows the texture of the layers of printing. I adds a nice aesthetic to the model

The connection of Hallows and Sphere Base...

Hallows slotted in right way up. This Hallows has the right slotting (2.75mm) to fit together the two pieces and for them to stay together.

Hallows slotted in upside down

With circuit inside base. Hallows does not slot all the way down because LED does not slot down into battery slot as far as it should 

Lights up very well with LED

Object 4: Deathly Hallows Sign Patterned

Software: Adobe Illustrator

Materials: Acrylic

Fabrication tools: Laser cutter

Rastered patterns on the Acrylic. It came out great. There were no scorch marks and the acrylic gained a white surface where it was rastered

Two different designs pieced together

With the LED. Shows a contrast between the white of the raster and clear acrylic

Up close you can see the texture of the rastered surface which is quite cool
