Abstract

In view of the wide use of titanium dioxide, more and more approaches to 3D printing of materials based on it have recently been developed, the most promising if which remains stereolithography 3D printing owing to high resolution and low power consumption. It was studied how the degree of crystallinity of titanium dioxide affects both the properties of the obtained suspensions for stereolithography 3D printing, and the sinterability of the printed bulk materials. It was shown that the use of amorphous titanium dioxide as a precursor increases the fraction of the inorganic phase in the suspension, which leads to a significantly smaller shrinkage in sintering. Despite the high critical energy of polymerization and the low photosensitivity of the produced suspensions, the use of amorphous titanium dioxide enabled one to completely remove the polymer binder by high-temperature annealing without significant deformation of the printed samples.

含二氧化钛悬浮液的立体光刻3D打印

摘要

鉴于二氧化钛的广泛使用，最近已经开发了越来越多的基于二氧化钛的材料的3D打印方法，由于高分辨率和低功耗，最有希望的方法仍然是立体光刻3D打印。研究了二氧化钛的结晶度如何影响所获得的用于立体光刻3D打印的悬浮液的性质以及所打印的散装材料的烧结性。结果表明，使用无定形二氧化钛作为前体会增加悬浮液中无机相的比例，从而导致烧结时的收缩明显变小。尽管聚合反应具有很高的临界能量，而且所产生的悬浮液的光敏性较低，
