Benchtop Machining of Self-Standing Alumina Doughs for Low-Number Fabrication and Prototyping

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

Cold isostatic pressing, gel casting, and protein coagulation are the most common techniques to produce green bodies prior computer numerical control (CNC)-based machining for near-net-scale shaping of ceramics. These methods typically involve various additives entail several steps create a body that is capable withstanding forces. Here, utilizing single additive, we first introduced facile benchtop method generate self-standing, malleable doughs alumina in under 2 min. We then optimized parameters CNC obtain surfaces with minimum surface roughness produced custom-sized crucibles as showcase low-number production. To consolidate dough from highly loaded suspensions alumina, employed poly(ethylene glycol)-grafted random copolymer acrylic acid N-[3-(dimethylamino)propyl]methacrylamide at 0.75 wt % respect weight powder. surveyed spindle speeds ranging 5000 30000 rpm cutting 1000 1800 mm/min using 1 mm tool sizes. The highest quality, characterized by minimal evaluated profilometry, was achieved speed 20000 1200 15000 tool. Upon sintering, hardness machined samples measured be 15.16 ± 1.15 GPa. Additionally, demonstrated recycling (up 30 content) sourced intentionally broken parts state. scheme contributes lowering use resources emphasizes possibility greener future ceramic production on broader scale. Overall, this cost-effective easy-to-implement methodology starts materials formulation level parametrization paves way immediate industrial adaptation.
