I’ll give it a try. Looking at the old thread you linked to, I now see how to orient the cutter to get a toehold.
When I’ve tried using just the spatula to pry the model off the platform, the spatula is able to lift one side of the tray. But the rest of the raft is so fixed to the build platform and so resistant to the lifting/prying force being applied, the raft breaks, then breaks the model, too, leaving the remainder of the tray and model still fixed to the build platform. Seeing a model and raft broken in half on the build platform after a 9-10 hour print is not a happy moment.
I’m sorry to have been dismissive, that was not my intent. The suggestion to sand the build platform is what people have recommended for some time on other threads to increase adhesion. It seemed very counter-intuitive and inconsistent with my experience. What I should have done was asked for clarification. No disrespect intended and I am thankful for your thoughts and explanation.
Please be advised I have had a superb experience with the many Form 2s I have had (still have 2). The Form 2 has become the basis for my business and a significant source of revenue for a family of 6. But over the last nine months I have become disgusted with the Form 3 having lost so much money and time trying to get the Form 3 to produce a single model I can sell. After being publicly scolded on this forum by gas-lighting participants (not you) in response to my posting photos of unsatisfactory Form 3 prints following firmware and PreFrom updates, I have become very cynical with respect to any suggestions that the Form 3’s significant, very real, harmful and costly problems can and should be solved by owner/operators. I should not have responded to your thoughtful post as though you were one of those people.
It was good news this month that in another thread that Form 3 owners were finally achieving good print quality using black V4. It seemed worthwhile to try what was being reported as working well for others, though a costly try. So, after throwing another $340 at the Form 3 last week buying a black resin cartridge and a new V2 tank in the hope that the Form 3 will finally be able to produce a sellable model, I was exasperated to find that I am breaking 1 out of 3 models trying to get them off the build platform. It seems that while Form 3 printing with black V4 does achieve the desired print quality, it does me no good breaking the models to get them off the build platform. While black V4 goes very far towards solving Form 3 print quality problems, black V4 creates a different, major problem that has to be solved.
But your suggested solution to the new problem sounds practical and helpful so I will give your technique a try.
IMHO, there’s a lot to like about the Form 3. For my business to continue to succeed, the Form 3 needs to print models as well as the Form 2 at all resolutions in all resins, without breaking models. It is getting much better.
Thanks!
