# Resin prints pulling away from build platform

My prints start out good, but seem to warp or pull away from the build platform at a later time. Should I divide up my support bases so they're not one big base? Should I sand/roughen the build platform for better adhesion?

• A 45° angle, even if rather extreme, can alter the forces extremely. Note that the tilt might actually provide a larger crosssection in some orientation, if this brings more surfaces into the fire: think a 1-unit long cube that rotates around X: the crosssection on the YZ plane is $1*(\cos{\alpha}+\sin{\alpha})$, but most bodies don't behave like cubes but like rectangular blocks with different a, b, c, then the crosssection is $ab \cos{\alpha}+bc \sin{\alpha}$. part of the trick is to make the change in average crosssection somewhat steady.
