If you build fused-filament-fabrication parts (the technology that RepRap uses) at room temperature, they have a tendency to curl as they cool from the bottom up. This is caused by higher layers shrinking as they cool, and bending the already-set lower layers upwards.

A heated build platform HBP greatly alleviates bad printing quality, by heating the beds surface in order to keep the base of an extruded part from cooling (and shrinking) too quickly. Such shrinking leads to warping; internal stresses in RP parts. The most common result is corners of parts lifting off the build surface. Heated beds usually yield higher quality finished builds with materials such as ABS and PLA. A HBP also permits one to print without the use of rafts!
