I'm a student artist trying to use 3D printing in my practice a bit. I'm working with liquid light, which is essentially a photosensitive liquid that you can apply to surfaces and later develop in the darkroom. I'm hoping to do this on 3D models that I print and was looking for advice on a good filament to print with that would absorb the liquid light. The manufacturer of the liquid recommends using a semi-gloss or glossy clear polyurethane to treat nonabsorbent surfaces, but I was hoping to avoid this. Anything would be appreciated and helpful!
PrusaSlicer (free, multi-platform) supports a feature known as fuzzy skin. Text below from linked page. Additionally, Cura slicer and Super Slicer also support this feature.
The Fuzzy skin feature lets you create a rough fiber-like texture on the sides of your models. If enabled, the perimeter will be resampled with a random step size and each new sample point will be shifted inside or outside of the perimeter by a random length limited by the Fuzzy skin thickness. This simple algorithm produces surprisingly nice results suitable for tool handles or just to give the print surface a new interesting look or to hide print imprecisions. You can also use modifiers to apply fuzzy skin only to a portion of your model.
This would result in a roughened surface, if the right parameters were used, allowing surface tension to secure itself while the "outward" or fuzzy portion might prevent shearing or peeling.
