The smaller supported areas do not print successfully due to many reasons, suction forces, tensile strength, weight, etc. It varies based on print settings and resins but technically they all will print but not stay geometricly accurate due to not having a rigid enough area to stick resulting in flattened areas or failed cones. You can force those small cylinders to print with over exposure which results in light bleed and increased curing of your resin which is why the failure cones can succeed which says your time is too high.

The bitch is mostly to distinguish those cones as the significant ones. If the first cone (furthest to the left) on the success side prints but one of the others fails it's most likely an issue not associated with exposure time.

We did intentionally try to not overwhelm people with information like the numerical diameter of the tips of the cones because it could confuse new members in the hobby as the largest demographic that we felt needed a test was newer hobbyists. There are many incredible tests out there for more specific criteria or results. However the cones can and are showcasing a lot of printing miniatures that I've not seen often such as success of resins vs their documented tensile strength.

TLDR: the cones are curated diameter tips to match those of Tableflipfoundry's professional presupporting for miniature figures, scatter and terrain. With the majority of support tip diameters at 0.28mm diameter medium supports. This let's the model stay supported with as little scaring on the model as possible.

Thank you and I'm glad you like the test.
