Have you ever done something stupid and while you're doing it know that it's stupid but you do it anyways, well that's what I did with my 3-D printed Bela head . I painted it with dark gray primer and then put it in the sun to dry as I made a mold of something else. I was thinking that the heat from the sun might distort the print , Then I thought that it takes more heat to melt the plastic then the sun would produce. Well the sun heated up the surface and the air inside the chambers inside to head and distorted the forehead. I painted white primer on it so I could see the damage. I can fix it but I wish I would've just listen to my own thoughts and not done this .The 3-D printer I used was a raise 3-D N2 plus.it took about 24 hours to print and you can see the size compared to my hand.
