We're looking at replacing the acrylic faceplate of the ICP with Epoxy Resin. This will help us improve mass production speed but we'll have to test it out first. By switching to epoxy resin:
the faceplate becomes 1 solid piece instead of 3 acrylic plates + 1 3D printed guide layered together
it's now possible to embed backlights directly into the plate
minimal surfacing will be required for a consistent finish
it's easier to mass produce
Here's a video of our first attempt to make the silicone mould.
