As I use sand-blasting techniques on my acrylic jewellery, I wanted to experiment with using the vinyl cutter to cut intricate shapes which I could then use as a resist on metal.
I performed experiments with each vinyl that Makernow have in stock to see which worked best, the colours that I tested were yellow, orange, grey and blue.
The first three had similar settings listed below:
Yellow - Offset - 0, Speed -14, Acceleration - 2, Cut force - 8
Orange - Offset - 0, Speed -14, Acceleration - 2, Cut force - 7
Grey - Offset - 0, Speed -12, Acceleration - 2, Cut force - 10
However the Blue vinyl is advertised as being specifically suitable for sand-blasting. It is quite a lot thicker and proved difficult to find the optimum settings for such an intricate design. In the end the settings that worked for me were: Offset - 0, Speed - 8, Acceleration - 2, Cut force - 28.
After cutting, I removed the vinyl from the backing and placed on cleaned (and slightly heated) metal.
The sand blaster/compressor unit that I use has a 25L tank, 2.5hp, approximately 9cfm (cubic feet per minute) using fine aluminium oxide sand and I have documented the results below.
