3D printing, a competitive manufacturing technology, has opened up new possibilities for fabricating complex structure ceramic components, but near-net forming is still difficult. This work presented a kind of near-net forming lithium aluminosilicate (LAS) glass-ceramics using direct ink writing (DIW) method by controlling thermal shrinkage. To achieve this goal, a high solid-loading ink was prepared using low thermal expansion LAS glass-ceramic powder containing β-spodumene as raw material. And we comprehensively evaluated the effects of the rheological properties of the slurry and sintering process on the thermal and mechanical performances. Attributed to the restricted sintering activity and thermal deformation of LAS glass-ceramic particles, the 3D-printed samples sintered at 1300 ◦C for 2 h showed an average linear shrinkage of 0.84% with a flexural strength of 45.59 ± 2.82 MPa and a compressive strength of 65.58 ± 3.99 MPa, respectively. The results suggested that LAS glass-ceramics were excellent candidate materials for near-net forming 3D printing.
