We’ve had a Form 2 for about 1.5 years. It used to be a workhorse that never failed. Over the past 3-6 months failures have been increasing and it’s to the point that I can hardly get a model to print without failing. Even “successes” have major defects that compromises the usability of the prints. Defects range from bulges of excess material to (of course) missing chunks.
We print in a variety of materials, but primarily tough, grey, and rigid. The big difference that I can see is that we’ve phased out all of our standard build tanks and moved to almost exclusively LT. On paper, they’re much more economical. I feel like the LT tanks may be generating peel problems because of the prevalence of missing chunks and patches of cured material that I have to peel off of the tank window after the print is “done”. Are the LT tanks the problem? What a waste of money if they are. Are the newer firmware/preform print settings worse? Not sure what to do.
Co-worker accidentally printed this with “mini rafts”. In this particular case, it may have contributed to the failure, but this is the first model that we’ve ever printed with “mini rafts”. Plenty of failures from other print settings.
