Hi All, I’ve been running lots and lots of tests to try and characterise the effects of laser flare. Basically it’s as previously described by @Monger_Designs and @RocusHalbasch - in that I am seeing bad flaking and corrugated surfaces on parts - on the faces of parts matching brightest flare side…

Well you know what they say about a picture painting a thousand words … The results from @KevinHolmes tall_thin_calibration_30mm_cross test. Printed in FormLabs v1 clear resin @ 0.5mm Layer Height. As @KevinHolmes predicted from my laser spot test the worst surfaces affected were those facing the…

There are so many factors that can make the photo messy and hard to pick out the importan…

[image] CraigBroady: No laser spot is a perfect circle. Creating a laser module with a spot that captures most of the energy within a specified diameter with tolerances both reliably and repeatedly is a classic engineering and product development challenge. Some amount of light outside of that d…

Or better yet, switch to DLP projection, Formlabs. Lasers are clearly full of problems.

Build volume would be VERY small. Not a problem for jewelry, but it would gouge a huge chunk out of Formlabs’ user base.
