QWhat type of Powder Bed Fusion is used?

A The following processes are repeated to form layers: Spreading resin powder, melting the resin with a laser or solvent, and then spreading new resin powder. There are two types of Powder Bed Fusion: Selective Laser Sintering and Multi Jet Fusion which uses special agents. Leona™ powder for PBF can be used for both Selective Laser Sintering and Multi Jet Fusion.

QHow many types of colored powder are available?

A Currently, we provide only white powder, but we are considering to prepare black powder in the future.

QWhat kind of material is "polyamide 66-based powder"?

A It is a material which is made by arranging the basic structure of polyamide 66.

With 3D printing it is possible to mold complicated shapes like hollow parts and thin-walled parts that are difficult to achieve by injection molding. Leona™ Powder therefore is suitable for 3D printing of vehicle interior parts.

Feature01

Wide molding window

During molding with a 3D printer, it is important to maintain a molten state (the intermediate state between the melting point and solidification point of the resin) to control the warpage and dimensional accuracy of the molded product. Leona™ powder for PBF has a wide molding window, allowing us to expect improved molding stability and design freedom.

Feature02

High heat resistance

Under a temperature of 80ºC, the strength of Leona™ powder for PBF is 1.5 times higher than that of the commonly used polyamide 12. Therefore, Leona™ Powder can be used for wider range of interior products.

Usage example01

Air ventilation parts

Air ventilation parts that blows cold or hot air is composed of multiple resin parts and requires an assembly process. In addition, higher heat resistance is required compared to the most of other vehicle interior parts. By utilizing the 3D printer technology it will be possible to eliminate the assembly process (which leads to significant cost down). Since it has higher heat resistance than polyamide 12, the production of thinner or smaller parts can be achieved.

Contribution to the environment

Leona™ powder for PBF, a new polyamide product, can reduce the weight of parts if it is used as the raw material. Furthermore, it enables the reduction of raw materials, inventories, and waste.
Leona™ powder for PBF contributes to achieve Sustainable Development Goals (SDGs): (7) Energy, (9) Innovation, (12) Production/Consumption, and (13) Climate Change.

Our unique nanocomposite materials are composites of highly heat-resistant cellulose nanofiber (CNF) and various polyamide resins. The materials excel in rigidity, dimensional stability, as well as sliding properties, and are expected to be applied to various sliding parts. They also contribute to reducing the environmental impact of parts since they utilize biomaterials, have high mechanical recyclability, and reduce the weight of parts.

With the increasing importance of environmental protection and with stricter regulations on CO2 emissions as well as fuel efficiency, the weight reduction of automobiles is becoming more and more important. Continuous Glass Fiber Reinforced Polyamide Resin (Continuous Glass Fiber) takes full advantage of the features of reinforced resin, this material has excellent strength, rigidity, and impact resistance. Therefore, the polyamide resin can be considered as an alternative to metals and contributes to the need for weight reduction.
