DELO offers powerful, high-performance materials for liquid additive manufacturing

DELO has further developed its liquid materials and opened up new opportunities for liquid additive manufacturing. These powerful, high-performance materials can be combined in one printing process and exhibit reliable adhesion and isotropic strength in all printing directions. These DELO materials are particularly suitable for use in the automotive industry and in microelectronics.

These liquid materials are light-cured epoxies modified for the 3D printing industry. These materials are tailored to the specific properties required by the customer, such as flexibility, transparency or conductivity, and are available in a wide range of product lines.

These high-performance materials have a similar chemical basis, can be perfectly combined with each other and form excellent adhesion, which is very suitable for material mixing. For example, materials ranging from hard to flexible can be used in one printing process. For this purpose, multiple dispensing heads are installed in the printer, which apply the corresponding liquid materials according to the specified parameters. Depending on the type of dispensing device, structures with a layer thickness of less than 500 µm can be achieved. For complex structures with extensions or cutouts, users can choose water-soluble support materials.

Since these versatile materials can be dispensed at room temperature, there is no need to heat the material or reserve space for heating equipment. With the help of UV light, these materials can be fully cured and reach their final strength in just a few seconds. This simplifies the process and saves energy.

Both the dispensing head and the curing lamp can be integrated into existing production lines, and ultimately allow the printing process to be combined with other production processes.

The properties of the cured DELO materials are comparable to those of high-performance plastics such as polyamide or PEEK. This is reflected primarily in their resistance to high temperatures and media. In addition, the material exhibits isotropic strength in all printing directions.
