Binder Jetting
Binder Jetting is, in some cases, categorized into MultiJet Printing
MultiJet Printing is a method that draws each layer and stacks it by jetting resin from inkjet head and are solidified them with a UV laser., which draws each layer by emitting binderAdhesives are also called binders or binding agents. In the Binder Jetting, the powder is bonded (cured) to form a cross section by printing this adhesive on the layered powder. from the head to the flattened powder and solidifying them. We’ll introduce the feature and printing process of Binder Jetting on this page.

How can we print 3D objects with Binder Jetting?
A tank with powder (usually gypsum) as material in it and the stage
A stage is the foundation on which moldings are printed in a 3D printer., which is the printing space, are lined up on either side of a plane.

▲The stageA stage is the foundation on which moldings are printed in a 3D printer. (The tank is in the groove)
The powder set in the tank is translated to a stageA stage is the foundation on which moldings are printed in a 3D printer. with a mechanism like a windscreen wiper and makes a thin layer.

The 3D printer jets the binderAdhesives are also called binders or binding agents. In the Binder Jetting, the powder is bonded (cured) to form a cross section by printing this adhesive on the layered powder. on the powder put on the stageA stage is the foundation on which moldings are printed in a 3D printer. by moving the stageA stage is the foundation on which moldings are printed in a 3D printer. and printhead to the XY axes. The jetted binderAdhesives are also called binders or binding agents. In the Binder Jetting, the powder is bonded (cured) to form a cross section by printing this adhesive on the layered powder. is dried and solidified with powder immediately. It looks like a cross between Selective Laser Sintering
Selective Laser Sintering is a method that draws each layer by emitting a laser to the flattened powder and solidifying them. and MultiJet PrintingMultiJet Printing is a method that draws each layer and stacks it by jetting resin from inkjet head and are solidified them with a UV laser..

▲Structure of Binder Jetting
The solidified powder descends with around powder for one layer and then the new powder adds to the top of them in a flattened form. And they have solidified again by jetting binderAdhesives are also called binders or binding agents. In the Binder Jetting, the powder is bonded (cured) to form a cross section by printing this adhesive on the layered powder..
The 3D object is created by repeating this process and stacking each layer.

By the way, you don't have to print support structures
Support structures is a pillar printed between the hollow part (overhang) and the stage to prevent extruded filaments from floating during modeling. because the extra powder accumulates at the bottom of the printing object.
This is how Binder Jetting prints 3D objects.
The 3D object created with Binder Jetting is not sturdy. Therefore, after removing surplus powder similar to Selective Laser SinteringSelective Laser Sintering is a method that draws each layer by emitting a laser to the flattened powder and solidifying them., you have to apply a hardener for finishing.
We will introduce the features of Binder Jetting.
You don't have to print support structuresSupport structures is a pillar printed between the hollow part (overhang) and the stage to prevent extruded filaments from floating during modeling. because the extra powder accumulates at the bottom of the printing object. Therefore, you can print a more elaborate and complex 3D objects.

Most products of this method can print full-color objects with the dyed binderAdhesives are also called binders or binding agents. In the Binder Jetting, the powder is bonded (cured) to form a cross section by printing this adhesive on the layered powder..

▲The printed objects with full-color
Material cost is inexpensive because it is using gypsum powder as material even though the printer is expensive.
Binder Jetting can print fast compared to other types of 3D printers because it solidifies material with the binderAdhesives are also called binders or binding agents. In the Binder Jetting, the powder is bonded (cured) to form a cross section by printing this adhesive on the layered powder..
Binder Jetting printers are usually over 5 million yen, which is expensive for individuals. The target customers are companies.
You have to prepare a depowdering station
In Selective Laser Sintering, Binder Jetting, a device that removes and reuses excess powder adhered after printing is completed. to remove the surplus powder. The vacuum cleaner and the dust extractor
A dust extractor is a device that collects dust from the air. are also required for you. Therefore, preparing these machines is an obstacle to introduction.

The printed objects with Binder Jetting become rough surfaces and low resolution because they use powder (gypsum) as a material. Therefore, it is difficult to make a smooth surface.
The printed objects are not sturdy and easy to break because they are composed of powder (gypsum) that is being solidified with just a binderAdhesives are also called binders or binding agents. In the Binder Jetting, the powder is bonded (cured) to form a cross section by printing this adhesive on the layered powder..
Binder Jetting is usually over 5 million yen and is too expensive as a
home-use 3D printer.
On the other hand, it can print fast and the material is inexpensive. Therefore, it is expected to print prototypes as industrial even though printed objects are not for final products
The final product is one that is actually sold to the consumers, not a prototype or sample. Functionality and durability are required. because of weakness.
These are the features of Binder Jetting.
We will show some pictures of Binder Jetting and its printed objects.
