This test was SLA (Stereolithography Apparatus) printed on Form 2 (Formlabs, Massachusetts). The material is black V2 resin and the files were orientated in PreForm (Formlabs, Massachusetts)
As the material is liquid resin, any cup geometry would cause a vacuum and damage the machine. I had to carefully angle the prints to ensure there is no cupped geometry facing into the resin, consider where the support structure is and how it will affect the interior of the eyecups and the magnet chambers.
The print took 16.17 hours for both the files in the orientation shown above with an additional 30 minutes in the Form Wash bath filled with IPA (isopropyl alcohol) and 20 minutes in the Form Cure UV (ultraviolet) chamber. The support material was removed prior to the alcohol bath as it is soft and comes away easily. It also creates a softer edge with reduced sharp surface bumps left by the support structure. I tried later removing some of the sharpness however this left more abrasions on the black resin and did not contribute to the model’s function. The print turned out very successful and with the high precision of Form 2’s completely negated the PLA print as the eye plate fits cleanly into the base holder and sits flush to the eyecups. Though this print is much heavier than PLA and would need a stronger armature to hold it in place.
