Cake is when a material “sticks” together with itself, leading to large spongy regions of powder.

This can be a serious problem during printing as it can lead to large amount of powder waste if the

caking material is not well controlled. It can lead to the failure of jobs due to the powder spreading

poorly hence poorly fused parts, and furthermore in some cases the material is unable to be

recycled. Elastomeric materials are more susceptible to caking, however it can occur in any powder

if the thermal process is not well controlled.
