Form 3: 15 hrs 51 mins

Form 2: 7 hrs 37 mins

Thank you for answer. Why form 2 is faster then form 3?

Wish we could tell you, maybe a smaller dot size or optimization issues. At this point, I wouldn’t buy a form 3 until it’s actually an upgrade to the form 2. As of right now it’s a side grade / downgrade depending on things you print. Smaller objects, it’s a downgrade due to what seems to be overexposure causing the resin to overcure and fill in smaller holes, larger objects a side grade but also a downgrade due to longer print times.

Thank you for advice.

Out of curiosity, was that at the same layer height?

Yes, both 0.1 mm. Seemed like a huge difference…Haven’t seen that big of a difference with other materials I have done, never done Black. 3.1.2. Preform. Most up to date Form 3 firmware.
