2, each heating tube individually heats the feeding pipes that device is encircled, and can provide respectively raw in feeding pipes
The melting temperature of object active material keeps different biomaterials in a molten state in its melting temperature, avoids processing temperature
When the bioactive materials that degree differs greatly heat together, after the lower material of melting temperature reaches molten condition, melting temperature
After higher material does not start also to melt or the higher material of melting temperature reaches molten condition, the lower material of melting temperature
Material loses activity since temperature is excessively high.
3, heating tube encircles feeding pipes, the bioactive materials in energy and Omnidirectional heating feeding pipes, to avoid life
The loss of object active material guarantees the consistency of the bioactive materials under molten condition.
4, different materials in a molten state are mixed by mixing chamber and spiral discharging channel, realizes life
The fusion of object material prints, and the product strength and precision printed in this way is high.
Further, auxiliary mixing device is additionally provided in the fusion nozzle housing.The purpose is to reinforce different molten conditions
Biomaterial mixability.
Further, the auxiliary mixing device is vibration of ultrasonic wave device, the vibration of ultrasonic wave device face mixing chamber.Pass through
The ultrasonic wave that vibration of ultrasonic wave device issues causes the high vibration of the particle of melted material, plays good stirring action, this
Sample is avoided is arranged stirring structure in mixing chamber, and making fusion nozzle housing, the structure can be simplified.
Further, flow distribution plate is equipped in multiple feeding-passages, flow distribution plate is located at the company of feeding-passage and mixing chamber
Logical place, flow distribution plate are equipped with several tap holes.Such setting has physics aggravation effect to melted material, flows into from tap hole
Mixing chamber will receive bigger pressure and spray, and different melted materials can be made mutually to collide fiercer, reinforce syncretizing effect, and pass through
Tap hole shunting is crossed, collision area is increased, further strengthens syncretizing effect.
