Dental LT Clear Turns to Yellow. Why?


#1

Anyone konws why LT Clear turns into yellow transparency and sticky after curing in the Formcure?

I do everything as its explained in the formlabs web.

Thanks in advance

Can you post a picture?

Some yellowing is to be expected in UV resins. The stickiness I would usually associate with inadequate cleaning. It is important to change out your IPA. My best results have been a 10 minutes soak in fresh IPA followed by using a sonicare toothbrush.

I’m having the same problem, but not with the stickiness. I’ve used the recommended Form Cure settings for the Dental LT clear and they’re turning yellowish brown. I let them dry for about 30 mins after having them in the wash, before using the cure. I’ve spent 2 days contacting Form Labs about it and sent them pictures but I’m still waiting on a reply.
