3D printers

A 3D printer is a machine that makes a three-dimensional object.
Based on the three-dimensional data generated by 3DCAD, etc., an object with an actual conformation can be made.

We are developing polyamide 66-based powders for powder bed melt-bonding 3D printers (Powder Bed Fusion, PBFs). It has high formability and heat resistance, and we aim to design parts with unprecedented shapes.
It contributes to the molding of hollow parts, thin-walled parts, and other parts with complex shapes, which were difficult with injection molding. In addition, it is more heat resistant than conventional polyamide powders (polyamide 12 and polyamide 11) and has a wider molding window, so it can be expected to be used for interior parts of office machines and interior parts of automobiles, which require heat resistance.

Wide shaping windows

During 3D printer shaping, it is essential to maintain the melting state (between the melting point and the solidification point of the resin) during shaping stably in order to control the warpage and dimensional accuracy of the shaped article. Leona’s powder for PBF has a wide range of shaping windows, which can be expected to increase the stability of shaping and the degree of freedom of shaping.

High heat resistance

The interior parts of automobiles are said to be nearly 80℃ due to direct sunlight. Leona’s powder for PBF has a strength 1.5 times higher than that of polyamide 12, which is common in an 80°C environment, so it can be expected to have a high degree of design freedom in automotive interior parts.

Automobile air vent

The air vent that blows cold air or hot air is composed of multiple resin parts, and requires an assembly process. In addition, high heat resistance is required among the interior parts. Taking advantage of 3D printer’s technique, we aim to omit the assembly process by integrating the complex shapes of the air vents. Higher heat resistance than polyamide 12 makes parts thinner and more compact. In addition, thanks to the high-degree-of-freedom of 3D printers, these printers can accommodate complex shapes that could not be achieved with injection molding, enabling the efficient flow of wind and the pursuit of high design.

Efforts for the Environment

Leona’s PBF powders, as a new line-up of polyamides, can be reduced in weight through resinification of components, and reduce raw materials, stocks, and waste, which are characteristic of 3D printers.
