Expansion Ink Printing

2.5D printing on media without patterning mask

Apply ink with dispersed microcapsules. After landing, it undergoes a drying process and sintering at around 100 ° C to expand the microcapsules and realize a 2.5D shape.

Features of Happy Japan expansion ink printing

Happy Japan expansion ink printing is on-demand digital printing, so it is ideal for 2.5D printing that requires flexible support as well as small-quantity printing.

What is on-demand expansion ink printing?

It is a 2.5D printing technology that can print expansion ink on any place. By heating after printing, the ink expands and realizes a 2.5D shape.

Depending on the ink composition and sintering conditions, it is possible to add functionality such as friction resistance and elasticity. The shape and hardness are devised according to the application, and it is expected to be used in various fields depending on the idea.

Apply exactly to the target position
Enables expansion ink printing, which was not possible with inkjet!
Form a solid with a small amount of ink
One-shot 2.5D formation without recoating with a small amount of ink!
Color and hardness as you like
Flexible support according to your needs and applications, such as hardness and adhesion to the objects.
Odorless and harmless water-based ink
The main component is water-safe water-based ink, which is almost odorless. There is no worry about the bad effects on the human body.

Ink ejection control technology

With inkjet technology, the movement of paper and the timing of ink ejection are delicately controlled, and the appropriate amount of ink is controlled to drip from the head ejection port to the target position. The shape and height of the vertical cross section of the dots, such as mountain-shaped and cylindrical, can be adjusted according to the customer’s request and application.

Main adjustment items

  • dot pitch
  • dot diameter
  • dot height
  • shape of vertical section
  • object characteristics
  • object size

Profile of vertical section

Ink formulation technology

For expansion ink printing, we use a unique low-viscosity water-based ink optimized for inkjet (uniformly and stably dispersed hydrophobic microcapsules with an average particle size of 10 μm and a specific gravity of 1.2).

Depending on the customer’s application, the hardness that demonstrates functionality and the adhesion to the corresponding object can be adjusted.
