1. The world's first model*1 of full color printing more than 10 million color tones

1) Applied UV curing inkjet method

3D printer [3DUJ-553] employing the [UV curing inkjet method], which performs modeling with UV ink (C, M, Y, K, White, Clear) printing, curing and piling layer by layer. Coloring is not by post processing but modeling while using color inks, which can produce an object of exquisite full color representation.

Modeling by a simultaneous print with color ink and support material ink of sliced data of 3D object.

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. According to modeling by color ink with high transparency, the outside light reflects on the surface of white ink layer, which will present a good colored modeling on the background of white layer.

Outside light will be reflective on the white layer thru color layer of object, the object shows a beautiful color of ink itself.

3) It is the world's first*1 technology ! Color profile is employed to enhance the color reproducibility

Color profile is employed to enhance color reproducibility.
It is the world's first technology*1 as an inkjet method 3D printer to apply color profile. By implementing a color simulation profile created by [MPM3] (option) to Adobe Photoshop, the color to be printed will be able to check on a PC monitor. The color of object displayed on the monitor can be approached to the object itself. It is effective to reduce the working time for color adjusting.

Reading the output profile to Photoshop can be checked the color of object on the PC monitor before modeling.

4) Broadening design possibilities with clear ink

Mimaki Pure Clear ink (PCL-110) can be used to express glass-like transparency as well as translucent colors by combining color ink with clear. Furthermore, by combining opaque models with Pure Clear ink (through "color in Pure Clear" or "color + Pure Clear"), it is possible to create models with truly clear expressions, for applications such as the visualization of internal structures. There are a wide variety of applications in a range of fields, allowing the freedom of creation to product designers and artists. It is also a vital tool to be used within medical and architectural models to promote deep comprehension through concrete visualization.
Note 1: Please install the “MH-110 Pure Clear ink (MH-110 PCL)” for pure clear 3D modeling
Note 2: Simultaneous installation of MH-100 Clear ink (MH-100 CL) is required for modeling with MH-110 Pure Clear.

Broadening design possibilities with clear ink

5) 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. Clear ink gives an additional effect to show a different image when the object is lighted from its inside. The combination of clear and color ink will broaden the design range.

Without the transmission of light, the contour of object is shown clearly.

With the transmission of light, a fantastic atmosphere appears. The color ink layer over the clear ink can create the expression of color translucency.

2. 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.

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

Acrylic resin is compounded in the ink to obtain the equivalent hardness of ABS resin, therefore over coating, drilling and attachment of screws are available.
They will give superior weather resistance and sufficient strength to maintain signs fitting with a created object, besides the brilliance of finish being adaptable to use as a final product due to the over coating.

Over coating can make a smoother surface and upgrade the weather resistance.

4. 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.

A space will be formed between the dragon and the ball after washing away the support material there. It will give a design option to rotate the dragon holding ball.

2) UV LED is applied as the curing light source

UV LED is applied as the curing light source

[3DUJ-553] 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.

5. Secured operation support to minimize losses

1) Equipment of the ink circulation print head prevents the nozzle clogging.

The world's first equipment*1 with the ink circulation print head as the 3D inkjet printer. Stable ink firing by the equipment of [Ink Circulation Print Head] for circulating of ink to prevent the ink pigment sedimentation. And this ink circulation system can remove air bubbles causing the nozzle clogging to keep optimizing the best condition of ink jetting.

2) [NCU (Nozzle Check Unit)] = Automatically detect and solve clogged nozzles


[NCU] as the world's first equipment*1 to [3DUJ-553] examines automatically the nozzle status by infrared sensor. When it detects a nozzle clogging, [NCU] performs the auto-clean to eliminate it. Detection frequency can be set per modeling data or by time. It forestalls a modeling loss after occurring a nozzle clogging.

3) Inner camera to watch modeling process

Inner camera

[Inner camera] is mounted for 3D printer operation and modeling process check from remote area. It allows constant check to minimize the loss of print error.
