Mimaki 3DUJ-2207 (Full Colour 3D Printer)


The “3DUJ-2207” is a Compact 3D printer with full-color modeling capabilities, able to produce more than 10 million colors through the UV curing inkjet method, which achieves high-definition color expression that is about twice that of the binder jetting (plaster powder) method.

The richness of color expression, which has been difficult to achieve with post-molding coloration, makes it ideal for use in fields that require precise prototypes, such as figure and toy designs, architectural models, and home appliances, where the slightest difference in color in industrial design can give an impression.

The “3DUJ-2207” has a compact design, can be loaded into an elevator without disassembling, has a small footprint and a quiet design with a deodorizer*, making it ideal for installation in office environments.
* Dedicated stand and deodorizer are optional (sold separately).

1. High-definition, beautiful 3D printing easily at your office!

High-definition, beautiful 3D printing easily at your office! : 3DUJ-2207

It is compact enough to be installed in an office environment as long as it has a footprint of 2.0 × 2.3 meters, with a noise reduction design and a built-in deodorizer.
(Dedicated stand and deodorizer are optional.)

2. Modeling by bright coloration full color ink

Modeling by color ink (CMYK,White,Clear) can achieve 84% of the Fogra 39L color gamut and cover 90% of SWOP gamut. With a color binder jet 3D printer, powder (plaster) appears on the surface, resulting in a whitish color, but using the UV curable inkjet method, the “3DUJ-2207” has beautiful color expression due to modeling with highly transparent color ink.

3. More flexible in designing with full color ink and clear ink !

Besides transparency, clear ink can make a color expression of translucency by the simultaneous apply of clear ink and color ink. The combination of clear and color ink will broaden the design range.

4. Remarkable expressive power for elaborate modeling by Mimaki’s concentrated technologies

1) High accuracy of ink drop placement technology amassed in Mimaki 2D printing experience

Thanks to Mimaki original wave form control and high precision ink firing technology, amassed in the development of inkjet printer for professionals full of their strict requirements of high quality image, our 3D printer’s precise ink droplet placement has achieved as completely aimed. This high accuracy can generate an elaborate modeling focused on detailed finishing.

2) Variable dot function for less granularity modeling

Variable dot function contains sorting to fire 3 dot sizes and selects always the optimal size for modeling. This specified function enables modeling of beautiful gradation of less granularity and extremely high accurate full color.

5. Excellent post process performance by availability of over coating and drilling

The ink uses acrylic resin and has the same strength as ABS, making it possible to drill holes and attach screws. In addition, overcoats can be used, making it possible to finish the final product for a different look.

6. Usability in pursuit of “easy fabrication”

1) Water soluble support material gives beautiful finishing with very simple operation.

The water soluble substance is applied for the support material utilized together for modeling. Therefore it will be washed away by soaking in water instead of scratching off.
It is convenient to be able to remove the support material of delicate designed object without damage.

* The removing time of support material depends on size and modeling configuration.

By removing the support material between the dragon and the sphere it holds, a gap is created between the dragon and the sphere, making it possible to design the sphere to rotate.

2) UV LED is applied as the curing light source

UV LED is applied as the curing light source

[3DUJ-2207] applies UV ink curing by irradiation of UV (Ultra Violet). The UV LED of curing source hardly exerts thermal influence to object and start time for lighting-up is not necessary. Long life and power saving can reduce the running cost.

Precautions for 3D modeling

 Precautions for 3D objects

  • Please make sure to execute an advanced evaluation regarding the physical property (strength, weather resistance, safety etc.) for estimated applications.
  • Depending on application, a post-processing might be necessary such as top coating or wiping by ethanol.

 Safety notice:
You are dealing with UV light sources that may harm your health. Please follow below guidelines strictly:

  • Do not look directly into the UV light source nor place your hand, or expose your skin directly to the UV light source.
  • Please make sure the room is well ventilated due to smells partially accompanying with 3D modeling.
  • Please use the attached goggles and globes when taking out an object or taking off support materials after modeling.
  • In addition, please read the instructions and guidelines of the manual carefully and follow those.
