1. Thumbs up for keep trying to remove himself of the gene pool

  2. What kind of watch is he wearing? I remember reading something about it on the book but I don’t remember if Evan mentioned the model.

  3. Great research job. Also something to consider is the evaporation of some of volatile components. I did a similar research and we noticed that some resins will start loosing reactivity after a few heat cycles. We weighted a Petri dish with a known amount resin and placed it in a oven for a X amount of time. We had some resins with a 20% loss. It also showed that it can be a hazard if the heated vat and printer don’t have proper ventilation or an air filtration system.

  4. That is fascinating! Do you have anything written in more detail?

  5. Yes, unfortunately I have an NDA and can provide too much details on it but I did a study on the final degree of polimerization vs resin temperature and variable printing speed according to resin reactivity.

  7. This is fascinating. How did you measure loss of reactivity? I noticed that resins that were cured over time did look richer/yellower. But it still cures nonetheless.

  8. I forgot to add, I exposed the resin several times, without the built plate let’s say 10s with 2 second delay 4 times.

  9. You can make an standardized test to measure loss of reactivity for any resin. Use a simple form or shape, like a rectangle or square. Set an exposure time of X seconds then measure the thickness in five points, corners and center. Do this when you open a new bottle and save the values and date on a spreadsheet. This will be your reference. If you are having issues down the road and you suspect that a resin is expired or isn’t curing properly you can compare the reactivity. I had a bottle that was 6 months over the expiration date, so I did this test and it didn’t show any loss. So I went ahead and printed some parts without any concern.
