I am so excited. I have been researching and developing these laser cut acrylic Matrix Dies since 2004 and I now have them available for everyone with the Paypal on my new Etsy store. There are Five shapes, Square, Triangle, Diamond, Rectangle, and Oval in sets of three sizes; 1-inch, 3/4-inch, and 1/2-inch for $20.00 a set.
The 1/2 inch acrylic Matrix Dies hold up really well. I have taught with them for the last 5 years to make sure they will hold up under regular use. In fact the first set of acrylic Matrix Dies, which I cut myself on the University of Washington's laser cutter in 2003 are still the ones I use to teach. I used the laser cut prototypes for these Matrix Die sets to make the bracelets and locket shown here. Just imagine the kind of artistic jewelry you can make with these laser cut Matrix Dies.
I have used my laser cut matrix dies with the 12-ton Bonny Doon Lite Manual Press, a 12-ton home made hydraulic press, a Harbor Freight floor model hydraulic press (scary), and the Mark III Bonny Doon 20-ton Deep Draw Press with the 4-inch riser block in place. The clear acrylic allows you to see your roll-printed metal through the die and capture just the part of your pattern you want to have on your piece of jewelry.
To use: peal off the protective paper film, use the die to select the area of your patterned metal, leave 1/4-inch of metal around all edges of the open area of the die, tape the metal in place over the open area of the die. Place the 1/2 inch thick acrylic Matrix Die down on the base platen with nothing underneath it. Stack the urethane on top of the metal, which is on top of the die. Pump the hydraulic press to achieve a 3-D formed shape. Anneal the metal and repeat the pressing to get a deeper draw. Thinner gauges of metal work best on the smaller shapes.
I have even used the dies in ways that they were not designed to be used to see how the 1/2-inch thick acrylic would respond. It is important when using these acrylic Matrix Dies to place them on the solid base platen of the hydraulic press (or on a solid riser block) and not on a urethane pad nor on top of the silver or copper, as improper stacking may cause the dies to crack.
