The Triple ACT® technology is a central component of the InnoventX Binder Jetting System. It is a patented powder application technology for dosing, distributing and compacting fine powder. ACT enables uniform powder application, resulting in a dense powder bed.

The X-Series precisely controls each individual process step:

• Ultrasonic unit for controlling the powder application
• Roller for distributing the powder
• Counter-rotating roller for compacting the powder

The entire system works together to achieve a standard deviation in the density of the green parts of less than 1% at printing speeds of over 150 mm/s.

The printhead is the heart of a binder jetting system. Two main types dominate the binder jetting sector, thermal and piezoelectric printheads, each of which has advantages and disadvantages.

The InnoventX system utilizes a piezoelectric printhead that can handle a wider range of viscosities, including binders with nanoparticles, and can deliver both droplets and jet streams, allowing for more complex binder application strategies.

The achievable material densities depend largely on the material used and the respective powder composition. In the binder jetting process, the proportion of fine powder in particular plays a decisive role. A fine powder content of less than 10 µm supports the formation of high green densities and subsequently enables high sintering densities and improved component quality.

In binder jetting, green part densities of up to 60 % and component densities after sintering of over 98 % can be achieved.

Changing materials is very easy thanks to the user-friendly design:

• Easy access to all system components enables thorough cleaning
• The construction job can be easily replaced
• Hopper (powder hopper) can be used and changed for specific materials.

The right sintering furnace is crucial for every binder jetting system. Only through sintering do metallic or ceramic components achieve their final strength and the desired material properties.

As a wide range of metallic and ceramic materials can be processed with the InnoventX system, the requirements for debinding and sintering cycles differ significantly depending on the material. Decisive factors include the maximum temperature, the process atmosphere and the cycle duration.

At AM Pioneers, we have been using the HTK 8 sintering furnace from Carbolite Gero for sintering metallic materials since 2025. The high-temperature laboratory furnace has a usable volume of 8 liters and reaches temperatures of up to 2,200 °C. This means that, in addition to standard materials such as stainless steel, demanding high-temperature materials such as molybdenum can also be reliably processed.

Another advantage of the HTK 8 is the flexible process atmosphere. The furnace can be operated in a hydrogen or argon atmosphere, for example, and is therefore suitable for a wide range of metallic applications. Thanks to the active cooling, comparatively short sintering cycles of around 24 hours are also possible.
