As Ease-Release is a mould release used on silicone moulds to help make them last longer, I thought it would be a good idea to use in on a resin tray. I mentioned it here a week or two ago and the idea wasn’t generally thought of as horrible, so I gave it a go on my last print.
The model I printed was two parts and quite big, it had a minor failure part-way through leaving a larger hole as the error had a bigger impact as it went. The area of the problem had a layer of uncured resin on the PDMS, so after the print I carefully removed this layer. It was quite well adhered to the PDMS layer and after I had (gently) removed it, I discovered a few spots of the PDMS had come away with the cured resin, rendering those areas unusable, This tray is near the end of its life so I’m not heartbroken, but a bit surprised that the ER400 didn’t do its job.
I’m running another print on the tray, using a different area and even though it is only 267 layers into 3264, each time it peels I can hear that it is sticking quite badly to the PDMS layer and un-sticking with quite a bang each time.
So, before concluding with my findings after this print completes (if it does successfully, which I am doubting, though so far it seems ok), at this point I’m feeling that Ease-Release 400 should NOT be used on the PDMS layer to aid the peeling process.
Hope this info is of use, I’ll report back after this print is finished.
