These include jewelry, prosthetics, figurines, ornaments, dcor, and art (e.g., installation). I also increased the exposure time by a second (from 8 to 9), but this was only to see if the object would be stronger and thus prevent the cracking. Ensure you use gloves, goggles, protective clothing like a long-sleeve, and a facemask. I am experimenting with hollowing it, then slicing it in half. Hollowing your models is especially important for larger ones. Resin printing, also known as vat polymerization, is a process that relies on photopolymerization. I went from having 0.5mm walls to 0.8mm but it still happened. Next up is generating the vent holes. In addition, a solid print will last longer and is more resistant to wear and tear, so some specialists might choose to use this method.
