Bad prints out of brand New Form 3

In addition to loss of accuracy on the platform side, artifacts that my Form 3 continues to experience with gray V4 include misshapen openings in the vertical plane and loss of surface detail. Those are serious artifacts making my models unsellable.

Some good news: print quality has certainly improved with the latest firmware updates at 100 microns, specifically surface smoothness.

But, I need circular openings to be circular, all the detail to be present, edges to be sharp, and printing success at 50 microns in order for the models to be sellable.

The artifacts shown in the photos below of an April 11, 2020 test print are typical. A test print completed last week was no better. Note that this test print was made at 100 microns in gray V4, a resolution and resin FL has certified for the Form 3. Even at that resolution, artifacts occurred with gray V4. Test prints at 50 microns exhibit artifacts that are worse with significant warping and layer shifting. The model shown in the photos below prints perfectly at 50 microns on a Form 2 with no visible artifacts at all.

These photos and many others have been sent to FL for evaluation. Discussions with FL reps indicate that the gray V4 issues are known to FL engineers and work is ongoing to correct them through Preform and firmware updates. As of this writing, Form 3 prints are not competitive within my market. Form 2 prints are highly competitive. Until the Form 3 can print as well or better than the Form 2 with gray V4 at any resolution, my business and livelihood remain dependent on the Form 2.

Compare the above photos to the test print shown below done on February 20th. You can see that the April 11 print is much better with respect to surface smoothness and edge sharpness. Opening shape is much better on the April 11 test print, But even the April 11 test print still falls noticeably well short of Form 2 print quality. Having said that, Form 3 PreForm and firmware updates are moving in a very good direction and print quality improvement is visible.
