Light jig

i got my 3D printed resin jig back a few days ago. It has been nearly ten years since I printed my last jig on the SLA resin machine at RCA. This one was printed on a much more modern machine called a form lab which can print in various types of resin. My model had to be scaled down slightly to fit the bed size of the machine.  The result of this has been that the tube sizes were too small and closed up making the jig unusable.  Although it looks great as an object I will need to rebuild this in CAD.

I have spent the last few days drawing up the jig for making the steel section of my bedroom light.  I have emailed this off to DJCAD to get printed in resin.  I have made the triangles about double the size of my jewellery work as I know how long it will take me to weld the piece together.  The last time I made something of this scale was my 3D printed bowl I made in 2007 which took 1,200,000 zaps of the laser and over a month of 9-5pm to make.  I am hoping the change in scale will cut down some of the build time by about a week.  I have also thought about what size of wire I will use to make the piece.

I usually use 0.5mm steel, which is about the thinnest you can laser weld.  I think I may use about 0.8mm for the light which will make it a little stronger also, but without taking away from the aesthetics.  I have made the holes on the jig 1mm with a 1mm wall thickness.  In the past I have made the holes smaller but this gives a higher risk of them filling with resin during the build.

Bedroom light

For one of my first projects I have been designing the light which will be in my bedroom in the shipping container. The designs for my bedroom are quite minimal with lots of hidden storage space. The light will be one of the few features within the room.


For many of my designs I was looking at quite organic forms. I have been interested in using ceramics within the piece. My designs eventually went full circle and I arrived back at my favourite technique of laser welding.

Out of the three final designs I came up with I am going to make the one with the closed top so that shadows will be projected around all of the room. I have also chosen to make the geodesic ceramic base as I feel this works better with my design than the plain version.

 

 Through some of my drawings I have been thinking about the power wires. Through discussion with my mentor I have came to the conclusion some kind of self charging light would be good so that no cables would be necessary, also adding to the aesthetics of the piece.
