Can my object have internal canals?

It is possible to have internal canals in an object but there are some limitations, the canals need to be at least 5 mm on average in diameter (this size might need to be larger depending on the length and form of the object).

Should the 5 mm minimum diameter not be respected, it is possible that there will be powder remaining inside the canal. Normally if the canal has a simple form that does not twist or does not have right angles, the excess powder can normally be removed with a paperclip or a needle.

Should the internal canal have several 90° bends, the excess powder will be very difficult to remove, if this is the case Sculpteo customer support team will be in contact with you before the printing of the object to see if you are willing to accept the risk.
