Rock 3D printing in-situ infiltration method
The invention discloses a rock 3D printing in-situ infiltration method which comprises the following steps: uniformly mixing quartz powder, feldspar powder, rock debris powder, clay powder and a curing agent according to the proportion of sandstone mineral components; the powder bed 3D printing technology is adopted to complete powder laying on the printing face; carrying out ink-jet printing on a binder on the printing surface according to the sandstone three-dimensional geometric model to form a section shape of the rock sample; an impregnant is extruded and printed on the printing surface according to three-dimensional space distribution of sandstone mineral components, and the requirements for chemical components and strength of different parts of a single section of the rock sample are met; preparing layer by layer to obtain an in-situ infiltration rock sample; sintering the printed rock sample at high temperature to complete mineralization transformation of the impregnant and strength improvement of the sample; according to the requirements of sample density and mineral components, the impregnant capable of being converted into different mineral components is extruded and printed layer by layer on the basis of a powder bed 3D printing technology, and finally, the rock sample which is closer to natural rock in strength and mineral component distribution is formed through layer-by-layer accumulation.
本发明公开了一种岩石3D打印原位浸渗方法，根据砂岩矿物成分比例，将石英粉末、长石粉末、岩屑粉末、黏土粉末和固化剂混合均匀；采用粉末床3D打印技术在打印面上完成铺粉；根据砂岩三维几何模型在打印面上喷墨打印粘结剂，形成岩石试样的截面形状；根据砂岩矿物成分三维空间分布在所述打印面上挤出打印浸渗剂，满足岩石试样在单一截面上不同部位的化学成分和强度的要求；逐层制备得到原位浸渗的岩石试样；将打印完成的岩石试样高温烧结完成浸渗剂矿化转变以及试样的强度提升；本发明按试样致密度和矿物成分需求，基于粉末床3D打印技术逐层挤出打印可转变成不同矿物成分的浸渗剂，最终逐层累积形成与天然岩石在强度和矿物成分分布上更为接近的岩石试样。
