A thought on 3d printing overlays


I think the idea of trying to print overlays using some kind of flexible material on the 3d printer is actually - as Sensel found in their own research - less than ideal. Instead, what I’m gonna try is to print a negative image design of the overlay in standard PLA but then pour silicone moulding compound into the negative. This should create a thin yet flexible overlay that ought to work much better. My Ender 3 can do 230mm wide so I should be able to just about cover the Morph. Of course, by default, the silicone is pink unless you purchase the clear catalyst, but you can buy pigment, so I’ve ordered 100g of blue, that should end up quite a nice colour. In theory you could also pour a layer in one colour to fill the pads then allow to partially cure, then pour another layer in a different colour to make the base, or even use different colours on different pads. I do wish the magnet situation would be clarified; there seems to be a real reluctance on Sensel’s part to disclose this. I believe there are 8 (I think) magnets which are positioned with north and south pole placement to identify particular overlays but the exact details remain a secret at present, which is regrettable. However you can of course download any one innovator’s overlay to the Morph at any point without having that overlay so it’s not a big deal at present.


Hi ajay m,
What kind of overlays you will print?
I’m just curious, I will try with neoprene, one day…


Hi Nico. I want to start with a two octave piano keyboard with the keys modelled on the kmi qunexus I have designed it and it looks playable i.e one octave stacked on top of the other. But now I have to wait until Sensel fix the 48 area limit which I didn’t know about when I purchased my device.


Neoprene works great! Have printed (or better: ordered in a print-shop) several overlays.
Downside: They don’t stick to the Morph, my workaround was to make them big enough to be able to put weights left and right of the morph on the overhanging parts. Doesn’t win a beauty price but works :slight_smile:
