Method for producing shaped articles made of carbon or graphite by 3D printing
The invention relates to a method for the simple production of shaped articles made of carbon or graphite by 3D printing. This is achieved by preparing a flowable polymer mixture from a UV-permeable and polymerizable polymer or cellulose and a UV-crosslinkable resin, in which the polymer mixture is mixed with a sugar and/or cellulose until the mixture has a consistency that enables it to be filled into and treated by a 3D printer, the method comprises the steps of mixing a UV-crosslinkable resin, homogenizing the mixture at room temperature or high temperatures up to about 60 DEG C, filling a 3D printer with the mixture, printing the shaped article layer by layer with the 3D printer while exposing to UV radiation for layer-by-layer crosslinking of the UV-crosslinkable resin, cleaning the shaped article, introducing the UV-procured shaped article into a furnace, and drying the shaped article. And stabilizing the UV-precured shaped article in air at a predetermined stabilization temperature until all volatile components have been degassed from the preformed shaped article, and subsequently subjecting the shaped article to a high temperature treatment in a furnace under a protective gas for carbonization or graphitization.
本发明涉及一种通过3D打印简单生产由碳或石墨制成的成型制品的方法。这是通过由UV可渗透且可聚合的聚合物或纤维素以及UV可交联的树脂制备可流动的聚合物混合物来实现的，其中将聚合物混合物与糖和/或纤维素混合，直到混合物具有使得其能够填充到3D打印机中并由其进行处理的稠度，在室温或高达约60℃的高温下使混合物均质化，用混合物填充3D打印机，用3D打印机逐层打印成型制品，同时暴露于UV辐射下用于逐层交联UV可交联的树脂，清洁成型制品，将UV预固化的成型制品引入炉中，并在预定的稳定温度下在空气中稳定UV预固化的成型制品，直到所有挥发性成分都已从预制的成型制品中脱气，以及随后在保护气体下在炉中对成型制品进行高温处理以进行碳化或石墨化。
