- the solid (un-melted) portion of the filaments inside the feeding channels acts like pistons to drive the melted liquid into the melting chamber wherein the modeling material and the colorant materials are mixed to obtain a colored fluid in accordance with a predetermined color pattern.
- the drive motors can be controlled to regulate the advancing rate of the colorant filaments in the secondary feeding channels so that the volumetric dispensing rate of the fluid can be closely controlled in accordance with the color pattern.
- Fig.1 is a schematic cross section view of an apparatus in accordance with the present invention
- a preferred embodiment of the present invention includes a printhead unit having a nozzle block 1 preferably made of a material with a thermal conductivity greater than 25 W/(m K), such as, for example, brass or simmilar metallic alloys.
- the nozzle block 1 encloses a melting chamber 2 which can be heated to a temperature sufficiently high for the filaments to liquify.
- the melting chamber 2 is surrounded by heater elements 20 and a temperature sensor that regulate the temperature inside the melting chamber 2 to a temperature of approximately 200°C to 240°C.
- the printhead unit is further provided with a plurality of feeding channels 3,4,5.
- a first primary feeding channel 3 is arranged between a supply of primary modeling material, preferably in
- Secondary feeding channels 4,5 are arranged in the nozzle block 1 for conveying the color filaments from the color filament supplies to the melting chamber 2.
- Drive means 6, 7, 8 are arranged in connection with each channel to drive the filaments inside the channels toward the melting chamber 2.
- An example of drive means comprises a plurality of drive rollers connected to one another by a suitable belt or chain drive and driven simultaneously by a stepper motor and a drive belt or chain.
- a plurality of idler rollers located opposite to drive rollers may work together therewith to grip the filament therebetween and to advance it toward the melting chamber 2 and therefrom to the dispensing nozzle 9.

- Heater elements 20 (in the form of a resistance heating tape or sleeve) are positioned around the lower portion of the melting chamber 2 for converting a leading portion of the filament material to a flowable fluid state.
- the solid (un-melted) portion of the filaments inside the feeding channels 3, 4, 5 act like pistons to drive the melted liquid for dispensing through a discharge orifice.
- the drive motor 6, 7, 8 can be controlled to regulate the advancing rate of the filament in the feeding channel 3, 4, 5 so that the volumetric dispensing rate of the fluid can be closely controlled.

- the nozzle block 1 comprises two colorant channels 4,5 in flow communication with the melting chamber 2, for conveying the colorant filament materials from colorant filament supplies to the melting chamber 2.
- Driving means are arranged in connection to each colorant channel to regulate the flow of colorant filament in accordance with a predetermined color pattern of the object. As the colorant filament is conveyed inside the melting chamber, it is converted from a solid state to a flowable fluid state and is thereby mixed together with the modeling material in order to form a colored fluid material which can be deposited through the dispensing nozzle.
- the object platform 10 is located in close, working proximity to the dispensing nozzle.
- the upper surface of the platform preferably has a flat region sufficiently large to accommodate the first few layers of the deposited material.
- the platform and the nozzle are equipped with mechanical drive means for moving the platform relative to the dispensing nozzle in three dimensions along the X-, Y-, and Z-axes in a rectangular coordinate system in a predetermined sequence and pattern, and for displacing the nozzle a predetermined incremental distance relative to the platform. This can be accomplished, for instance, by allowing the platform to be driven by three linear motion devices, which are powered by three stepper motors to provide movements along the X-, Y-, and Z-directions, respectively.
- Motor means are preferably high resolution reversible stepper motors, although other types of drive motors may be used, including linear motors, servomotors, synchronous motors, D.C. motors, and fluid motors.
- Mechanical drive means including linear motion devices, motors, and gantry type positioning stages are well known in the art.
- Z-axis movements are effected to displace the platform relative to the nozzle or to displace the nozzle relative to the platform and, hence, relative to each layer deposited prior to the start of the formation of each successive layer.
- the nozzle and other hardware attached to the nozzle may be mounted in a known fashion for movement in the X-Y plane, with the
- INCORPORATED BY REFERENCE (RULE 20.6) platform supported for separate movement toward and away from the nozzle along the Z-direction.
- the platform may be supported for movement in the X-Y plane, with the nozzle mounted for separate movement along the Z-direction toward and away from the platform.
- Another alternative is to have the movements in the X-Y plane and in the Z-direction all to be carried out by either the platform only or by the nozzle only. It will be understood that movement in the X-Y plane need not be limited to movement in orthogonal directions, but may include movement in radial, tangential, arcuate and other directions in the X-Y plane.
