Hi -
As promised, below is a part I printed using a combination of the guidelines from that video and the “breakaway tab” I mentioned earlier . For this particular part I DID NOT rotate on two axis, but only one and the results have been far better than anything I have had so far.
Based on the the pixel size of the the Form4 (from what I could find 50 micron) and the fact that I was printing on 50 micron layer height, the “ideal angle” based on the calculation was 45º. This made it easy to orient the part in such a way that two perpendicular sides were both at 45º angles to the build platform. See image below:
Below is the result:
I can confirm, all sides are at 90º (or VERY close) and free from any layer lines with the exception of one small area indicated by the red arrow. No warping at all on the 25 parts printed.
I know this is early days, will try the same logic on another model and see if it holds true.
Regards, Friedl.
