Binder Jetting, also known as 3D printing, is an additive manufacturing technology that uses the selective application of binding fluids to bond powdered materials in layers. In simplistic terms, the technology is similar to a classic inkjet printer.

But instead of applying ink to a sheet of paper to create a two-dimensional product, Binder Jetting 3D printing systems work in a three-dimensional powder-bed approach by selectively and precisely bonding individual layers of powder together to create a three-dimensional product.

The Binder Jetting process

As with most additive manufacturing processes, Binder Jetting is also based on digital CAD data sets. These are “sliced” by the print software into extremely thin layers. Two key components then work together in the printing system: the recoater and the print head. The recoater applies a micrometer-thin layer of powder material to be printed onto a building platform.

The print head then passes over the platform and selectively applies a binder to those areas of the building platform where the component is to be printed according to the sliced data set. The platform is then lowered by exactly one layer thickness and the recoater applies a new layer of powder, which is again selectively bonded by the print head.

These process steps are repeated until the component is completely printed within the powder bed. The component can then be unpacked from the box and cleaned of excess, non-bonded material.

Binder jetting from voxeljet ensure competitive advantages - technically and economically.

Advantage of material variety

Material diversity

Almost any powder material can be bonded with a complementary binder. No matter if sand, ceramic or plastic.

Advantage of geometric and design freedom

Geometric freedom

Due to layered-based printing, even the most complex part geometries can be realized. The powder bed has a stabilizing effect so that no support structures are necessary.

Advantage of speed

Speed

Thanks to the possibility of using industrial printing modules, Binder Jetting systems can achieve very high printing speeds.

Advantage of precision

Precision

Piezoelectric print heads are characterized by outstanding precision and edge sharpness.

Advantage of output

Scalability

The Binder Jetting process technology can be easily scaled to larger output margins by enlarging the print heads

Advantage of compatibility

Compatibility

Due to the high material variety, the material sets of the Binder Jetting systems can be adapted to existing production environments in order to integrate them into existing value chains.

Materials.

voxeljet is one of the pioneers of the first hour when it comes to establishing 3D production processes in professional or industrial environments. Whether you want to produce design models, functional models, cores and molds for investment or sand casting. In plastic, ceramics or sand. Our powder binder jetting process, which were specially developed for industrial use, are among the best the market has to offer worldwide. Especially when volume, efficiency and speed in production are important. Our 3D printer support a wide range of material combinations for even greater flexibility.
