A new technique! Splicing!!

After today’s class, having consulted with Brad, I have decided to create my third project, the ‘Twister Cuff’ in a different manner.  Rather than following the path that I am currently on, where I create individual files that continue off each other, I am going to use a technique called ‘Splicing’.  Splicing will allow me to cut a 3D file into a series of layers of which I can determine the thickness (most likely 3mm, the same thickness as my acrylic).  This technique will ensure a more accurate and smooth final piece.

Project 3: 'Twister Cuff'

The start of my CAD construction for this project:

Stage 1:

Stage 2:

Stage 3:

Stage 4:

Stage 5:

  

And so on for many, many cuts, hopefully ending up looking like some cone/twister like form.

 

Note: Explore "Grasshopper" as a possible 'splicing' technique

Further Development on Project 3

Thinking more about Project 3, I have started to liken my design to that of a Cyclone or a Twister.  The piece starts off one way and then grows outward, constantly warping and changing.  As the piece grows longer it may grow wider or thin out, I am yet to decide.

Project 3: Laser Cut 3D Piece

For Project 3 I would like to continue to explore the design that I came up with for Project 2.  Obviously I will delve much deeper into both the concept and design but I think that this is a good place to start.

Continuing on the line of the Octagonal Bangle I would like to start to play with the flow and growth of the piece.  I want my new piece to warp as it grows.  This 3D piece is looking like it will be far larger than my first piece.

Reflection on Project 2

I am very happy with the 2D laser cut piece that I have created for Project 2.  It is a simple yet effective and aesthetically appealing.  It was cheap and easy to make and it was a nice way to introduce myself to the work of rapid prototyping.

Looking forward to more!!

Octagonal Bangle Laser Cut

Using the Laser Cutter, I have cut a series of Octagonal Bangles.  There are six different files:

1. small bangle with octagonal holes (3mm)

2. small bangle with round holes (3mm)

3. small bangle with round holes (6mm)

4. large bangle with octagonal holes (3mm)

5. large bangle with round holes (3mm)
6. large bangle with round holes (6mm)

Using the Large octagonal bangle with 5mm round holes I created the piece above.  I riveted the three pieces of acrylic together with 5mm sterling silver chenier and flared out the chenier using a collet punch.

However I got a bit too excited on one rivet and accidentally cracked the acrylic.  To fix/fill this crack i used 5 minute Araldite mixed with a little bit of black ink.  I lightly dabbed the epoxy resin adhesive onto the crack and then, using a thin straw cut to a point,  blew the resin into the crack.  This allowed it to fill the crack slightly and will give the structure a bit of strength.  Luckily there is no major damage to the piece.
