I recently used it for fixing MTH LED lighting that the small staples or attachment points had come loose or were lost when the original LED string was ripped off the shell and damaged. The advantage is this is a non conductive method of attachment while also not damaging the paint or becoming ugly. Example things like CA glue can leave a white film or mist from the fumes, where this can be controlled, even wiped off before controlled UV curing.
Basically, it is the same UV cured resins used in 3D printing methods, but slightly more gelled rather than the much thinner liquids required and used in 3D printing. I don't know what they use as a thickener, but for critical tasks where CA glue and accelerator may not be ideal because of the fume and white film might not be ideal, this is great for those detail part attachment items where you need to control the glue, not have it set until the part is in place, and not leave any traces or other film problems as the glue cures.
Again, this is darn impressive and honestly I think it's the combination of 3D printing making the resins base materials and chemical combinations more readily availaable and driving the cost down that kind of kicked this off. As stated, yes, Dentists used this for some time but because that is limited and medical, the costs were just much higher and largely impractical.
This is ideal for gluing in windows and other details where you may need to position the part, you do not want fumes or other problems, you can instantly cure it with the UV light source in place once in final position.
