Binder jetting is an additive manufacturing technique in which powdered material is sequentially laid down and printed on by an ink binder, in a selective manner, to form a 3D object. Unfortunately work in this area relevant to food materials is largely unpublished, however a typical application of this technique is sugar powder bound by a water and alcohol based ink with optional colour or flavour demonstrated by commercial ventures. In this work we demonstrate the use of a small scale powder layering device under an ink jet printer to test prototype powders prior to producing quantities typically used in commercially available binder jetting machines. Powders comprising predominantly of ball milled, amorphous cellulose were successfully used to create 3D structures when interacting polysaccharides were present in the ink (xanthan gum) and as a proportion of the powder component (glucomannan) by inducing selective recrystallization. These ingredients are categorized as dietary fibre, thus such formulations can be used to create low-calorie 3D printed food designs to be used within food products.
粉末层积喷射是一种增材制造技术，其中粉末材料通过喷墨粘合剂以选择性的方式顺序铺设和打印，以形成 3D 物体。不幸的是，与食品材料相关的这方面工作在很大程度上尚未公布，然而，该技术的一个典型应用是糖粉通过水和酒精基油墨结合，具有可选的颜色或味道，由商业企业展示。在这项工作中，我们展示了在喷墨打印机下使用小型粉末分层装置来测试原型粉末，然后再生产通常用于商业上可用的粉末层积喷射机中的数量。当油墨（黄原胶）中存在相互作用的多糖和作为粉末成分的一部分（葡甘露聚糖）的比例存在时，由诱导选择性再结晶，主要由球磨无定形纤维素组成的粉末成功地用于创建 3D 结构。这些成分被归类为膳食纤维，因此这种配方可用于创建低卡路里的 3D 打印食品设计，用于食品产品中。
