In 2019, Israeli 3D printing company Tritone launched MoldJet, a novel production process that integrates 3D printing, metal injection, CNC machining and other technologies. After 2 years of polishing, the technology has now been integrated into the Tritone DOMINANT system and officially launched. Through six steps, high-quality metal parts can be mass-produced.
DOMINANT’s metal 3D printing system includes six trays and six stations. The trays are moved from one station to another to produce metal parts. The following is the specific division of labor for the six stations.
The first station, 3D printing the mold. Using one plastic material and 4 nozzles, molds of various structures can be quickly printed.
The second station, metal injection. First, the roller will pass over the surface of the mold to smooth the surface of the mold; then a slurry of metal powder and a binder is injected into the mold; then the blade is slid across the slurry to remove excess material.
The third station, hardening. Using heat and vacuum, the water in the slurry was evaporated and compacted.
The fourth station, quality inspection. Through a high-resolution camera, the details of the surface of the part are captured, and the parts with unqualified quality will be eliminated after analysis by the AI algorithm.
The fifth station, low temperature furnace. By sintering, the plastic mold is removed, and the density of the metal parts is increased to improve the strength of the parts. After testing, the density of metal parts can reach more than 99%.
The sixth station, CNC machining. This is an option, and parts that require precision can be processed by CNC to further improve the precision.
Through this form of turntable, 6 stations can work at the same time, and different materials can be seamlessly switched, which greatly improves work efficiency. The current output of the DOMINANT system is approximately 1.6 liters per hour.
