PROBLEM TO BE SOLVED: To provide a compact additive manufacturing apparatus which can slide squeegees while inclining them.SOLUTION: An additive manufacturing apparatus includes: a first squeegee 11a which is rotatable about a first shaft Sa; a first drive part Ma which slides the first squeegee 11a in a first direction, a second squeegee 11b which is rotatable about a second shaft Sb and slidably connected to the first squeegee 11a; a second drive part Mb which slides the second squeegee 11b in the first direction; a powder supply part 14 which supplies a powder between the first and second squeegees 11a and 11b arranged so as to face each other; and a light irradiating part 8 which irradiates a light beam LB to a powder layer formed by sliding the first and second squeegees 11a and 11b in the first direction. 【課題】スキージを傾斜させながらスライド可能であって、コンパクトな積層造形装置を提供すること。【解決手段】第１の軸Ｓａを中心として回転可能な第１のスキージ１１ａと、第１のスキージ１１ａを第１の方向にスライドさせる第１の駆動部Ｍａと、第２の軸Ｓｂを中心として回転可能であるとともに、第１のスキージ１１ａとスライド可能に連結された第２のスキージ１１ｂと、第２のスキージ１１ｂを第１の方向にスライドさせる第２の駆動部Ｍｂと、対向配置された第１及び第２のスキージ１１ａ、１１ｂの間に粉末を供給する粉末供給部１４と、第１及び第２のスキージ１１ａ、１１ｂが第１の方向にスライドすることにより形成された粉末層に光ビームＬＢを照射する光照射部８と、を備えた積層造形装置。【選択図】図６
