RAPID FORMING APPARATUS AND METHOD BASED ON METAL CARBONYL COMPLEXES IN 3D PRINTING

摘要

Provided are a rapid forming apparatus and method in 3D printing by using metal carbonyl complexes as raw materials. The apparatus comprises a gas inlet (1), a glove box (2), a spray nozzle (3), a sedimentation workbench (5), a platform heater (6), a gas-liquid collector (7), a collector exhaust pipe (8), a gas outlet pipe (9), a gas condenser (10), a spray nozzle control circuit (11), a servo mechanism (12), a servo mechanism control circuit (13), a liquid-state metal carbonyl complex control circuit (14), a computer (15), a solid-state metal carbonyl complex-ether solution control circuit (16), a solution heater (17), a flow meter I (18), a solution storage tank (19), a liquid storage tank (20), a flow meter II (21), a liquid-state metal carbonyl complex conveying pipe (22), a solid-state metal carbonyl complex-ether solution conveying pipe (23), a liquid heater (24), a drive pump (25), and a glove box operation opening (26). Transition metal carbonyl complexes such as iron, nickel, cobalt and chromium are used as raw materials, and can be used for printing a metal model with a variety of elements. Because the metal carbonyl complexes become pure metal after thermal decomposition, the quantity of impurities is effectively reduced, thereby improving product quality.
