Ok, this may be a weird question, but the other day I printed a bracelet for my girl friend, using makerbot PLA. She wore it for approximately 2 hours before complaining that it was itching her wrist. She took it off and had these red hive-looking bumps. She took a benadril and the bumps went away within an hour. However, she now refuses to wear it, and I kinda feel bad. Has anyone ever had this sort of reaction to PLA before, or know if it is even possible? Could it be something else that caused this?
