PROBLEM TO BE SOLVED: To provide an inkjet printhead allowing a high-viscosity material to be used in an additive manufacturing process using the printhead.SOLUTION: A pin actuated printhead includes an orifice through which a material is ejected, a chamber to hold the material to be ejected, a channel connecting the chamber to the orifice, and an actuated pin, to enter the orifice and to eject the material from the orifice. The printhead is configured to eject a material with a viscosity of 10,000 cP or more at an elevated temperature.SELECTED DRAWING: None 【課題】インクジェットの印字ヘッドを使用した付加的製造プロセスにおいて、高粘度材料を使用できる印字ヘッドの提供。【解決手段】ピン駆動型印字ヘッドは、材料が排出される開口部、排出される材料を保持するためのチャンバ、チャンバを開口部と接続するチャネル、および、駆動ピンを含み、開口部へ入り材料を開口部から排出する。印字ヘッドは、高温で１０，０００ｃＰ以上の粘度を有する材料を排出するよう構成される。【選択図】なし
