Abstract
A three-dimensional printing apparatus for forming a three-dimensional object is provided. The three-dimensional printing apparatus includes a forming unit to supply a powder to form a powder layer and a head to eject liquid droplets of a forming liquid onto the powder layer to bond particles of the powder layer to form a forming layer. The forming unit and the head form laminated forming layers by sequentially repeating forming the powder layer and ejecting the forming liquid to form a between-layers vacant space formed between the two successive forming layers sequentially laminated in the laminating direction.
