The 3L seamline was originally demarked as an “overlap region” in Preform:
But now it’s just a dashed line:
And this article says:
PreForm instructs the rear LPU to print the rear half of the build volume, and instructs the front LPU to print the front half of the build volume.
Does this mean a quarter of the length of each LPU (towards the middle) is never used?
What motivated the change?
If I’m printing a part that’s ~2/3 of the width of the build area is there any way to avoid a seamline?
Does the old behavior apply if I use an older version of Preform with the latest firmware?
Does Formlabs have any plans to give us a toggle in Preform to pick whether to optimize for speed or quality? (especially for a print that distributes naturally into the physical LPU zones - e.g. If I’m printing a part that would fit entirely in the region of one LPU along with a second, long, narrow part that fits in the non-overlapping region of the other LPU, and I want no seamline)?
