FDM Method (Fused Deposition Modeling)

Modeling Method

Modeling three-dimensional objects by laminating resin materials (filaments) melted by heat

Complete modeling by laminating real materials in fine filament like single stroke of brush. * Place it on non-stackable support material and do modeling.

Internal structure of modeling

  • Solid
  • Sparse
  • Sparse (Hexagonal)
  • Sparse (Double-dense)

It is possible to reduce weight while securing strength by changing the internal structure.

Application (Recommended for the following cases)

Useable for ABS, ASA, ULTEM and other material (total 12 types). For modeling small lot parts, prototypes and manufacturing tools in automotive and home appliances that require high heat resistance and weather resistance. Biocompatible material is selectable for medical equipment's application.


  • Excellent performance in processing speed, capacity and processing accuracy
  • A machine that is capable to do large size printing. Possible to do modeling up to 914 × 610 × 914 mm
  • Variety of materials (12 types) are selectable according to application and purpose, such as antistatic, biocompatibility, incombustibility and others

Selective Laser Sintering Method (SLS Method)

Modeling method

Spread the Nylon powder in 0.1mm lamination pitch, irradiate laser at the specific area of the slice data to do modeling.

Use laser to melt section to be modeled. Non-sintered powders support the structure to create hollow structure modeling.

Applications (Recommended in the following cases)

Remaining powder supports sintered parts, resulted in eliminating the need of further support material which usually is required in many other 3D printing technologies for the purpose of preventing a product from collapsing during the course of manufacturing.


  • High-end machine and only a few units are installed in Japan
  • Demonstrate high heat resistance
  • Realize high toughness and strength
  • No need binder and support material
  • Biocompatible material
  • Gears
  • Robot arm hands
  • Robot arm hands
  • Rebar arrangement model
  • Honeycomb structures

Polyjet Method

Modeling method (Explanation of technique)

Modeling a model by injecting liquid polymer from nozzles based on slice data created from 3D CAD data and curing it by UV light.

Spray acrylic liquid and cure by UV light * Do modeling with layout so that support material does not stick easily

Application (Recommended for the following cases)

Spray different materials simultaneously from 3 cartridges. It combines materials to control hardness, color and transparency, and do modeling for models with parts made of three colors.


  • Express complex shapes and intricate detail elaborately. Reproduce precise model with smooth surface
  • Simultaneous molding with multiple resin simultaneous injection (multi-material) with multi-color up to 46 colors
  • Rich color variations for ABS-like, PP-like, transparent material and soft materials
  • Able to achieve realize rubber-like hardness (Shore A) of 27° to 95° by combining multiple materials
  • Bridge rebar visualization model
  • Simple resin type
  • Brain and blood vessel
  • Liver
  • Soft material with different hardness
