Transparent Resin
Posted on
Transparent, clear resin can make for interesting results. Compared to other resins, it has two interesting properties:
- Light passes through clear resin much more easily
- Light is much more likely to bleed
This means that fine detail is difficult to achieve (impossible, in my experience). Light bleeding means resin cures in places it shouldn't and detail is lost. The effect is further amplified because a higher exposure time is needed.
It's likely that these problems are the reason clear resin can often be bought for a lower price than other colours. If transparency is not strictly needed, alcohol ink can help restore the ability to print fine detail for cheap.
Adding between 0.5 % and 1 % alcohol ink to any amount of clear resin will visibly tint the resin (obviously). More importantly, this ratio decreases light bleeding by enough to vastly improve fine details.
