Sometimes when printing without a raft, you may notice that the first layer is slightly larger than the rest; this is elephant’s foot.
While most of the time it is unnoticeable and unimportant, it can pose a large problem when printing objects for practical applications. It drastically decreases tolerances, making it much harder to fit pieces together.
This defect often arises in larger prints, as it is caused by the weight of the object pushing down on the first layer. If it is not fully cooled, this weight results in the bulging first layer.
Elephant’s foot most often occurs as the result of an uncooled first layer. If the temperature of the print bed is too high, or if there is insufficient cooling, the first layer may not cool properly, causing elephant’s foot.
