Dual asymmetric centrifuge mixing
3-D Printing
Additive Manufacturing
The Hauschild SpeedMixer® helps prepare uniform pastes, resins and filled materials used in 3D printing and additive manufacturing. Its fast, bladeless mixing gives consistent dispersion of pigments, powders and modifiers, which improves printability and mechanical performance. It also supports quick formulation adjustments, making it valuable for prototyping and production workflows.
Hauschild SpeedMixer® handles an extremely broad variety of applications, making it ideal for countless materials and industries.
The Hauschild SpeedMixer® is widely referenced in patents and scientific literature dealing with 3D printing and additive manufacturing, particularly in areas where material uniformity, degassing and controlled dispersion are essential. Many formulations used in printing rely on highly filled or reactive systems, and the SpeedMixer helps prepare these mixtures quickly and consistently in sealed containers. In resin-based additive manufacturing, it is used to disperse pigments, nanoparticles, rheology modifiers and photoinitiators into UV-curable matrices, ensuring smooth printing, predictable curing and minimal optical defects. Several studies describe its role in preparing ceramic, metal-oxide and composite slurries for stereolithography, where fine dispersion and bubble-free mixtures are critical for layer accuracy.
In silicone and elastomer jetting, the SpeedMixer is employed to blend high-viscosity polymers with fumed silica, crosslinkers and catalysts. This produces shear-thinning materials that can be jetted or extruded with stable droplet formation. Recent patents highlight its importance in formulations designed for ballistic deposition, where consistent rheology determines print quality. In thermoplastic and composite filament development, the SpeedMixer helps mix additives, colorants and functional fillers before extrusion, allowing researchers to tune electrical, thermal or mechanical properties.
The tool is also widely used in experimental work on conductive, flexible and stretchable materials. Studies involving CNT- or graphene-reinforced elastomers often rely on the SpeedMixer to achieve uniform dispersion without damaging the nanomaterials. In metal and ceramic additive manufacturing, it supports the preparation of pastes and binder systems for printing dense, defect-free structures. Across these areas, the SpeedMixer enables reproducible formulations, fast iteration during R&D and a clean, air-free process that improves both print performance and material reliability.

Silica molded bodies having low thermal conductivity
US 2019 / 0016634 A1 – Wacker Chemie AG
This patent describes silicone rubber compositions engineered for ballistic 3D printing. By controlling viscosity and shear-thinning behavior, the materials can be jetted reliably to form elastomeric parts with high mechanical strength. The work identifies critical rheological parameters and demonstrates successful printing using UV-activated crosslinking and precisely tuned filler–polymer interactions.
Ceramic and glass ceramic slip for stereolithography
This patent introduces stereolithography slurries for fabricating ceramic and glass-ceramic parts. The formulations contain polymerizable monomers, photoinitiators, ceramic or glass-ceramic powders, and a nonionic surfactant. The surfactant stabilizes the slurry, prevents sedimentation, improves green-body strength, eases debinding, and enables the production of dense, high-precision dental restorations.
