Silica and alumina for Additive Manufacturing: 3D Printing applications
3D printing has recently become viable due to the improvement both in usability and in material quality and strength. Evonik provides a variety of solutions to improve your 3D printing materials and processes.
3D printing, also known as additive manufacturing (AM), refers to processes in which successive layers of material are formed under computer control to create a three-dimensional object. There are several ways to print, all of which are additive and differ mainly in the way layers are built to create the final object. Some methods involve melting or softening material to produce the layers. Selective laser sintering (SLS) and fused deposition modeling (FDM) are the most common technologies for this type of 3D printing. Another method involves curing a photo-reactive resin with a UV laser or another similar power source one layer at a time. The most common technology for this method is called stereolithography (SLA). Most of these technologies are based on organic resins or plastics, but can also be used with inorganic metals, ceramics, or glass, as well as hybrids or composites.
Evonik offers highly specialized inorganic particles for use with different 3D printing materials, such as polymers, ceramics, and metals for a variety of printing technologies and processes, to improve the manufacturing, quality, and performance of printed objects.
AEROSIL® fumed silica, AEROXIDE® fumed metal oxides, and AERODISP® homogeneous dispersions of fumed silica or fumed metal oxides are highly versatile products that lend various properties to 3D printing materials. Typical applications include the following:
Powder free flow, anti-caking and electrostatic charge control for SLS and SLA
Density control in powder packing
Viscosity control over resin-based jetting systems (e.g. UV/EB curing)
Reinforcement of soft or elastic polymer systems and binder systems
Improvement of chemical and mechanical resistance of the final parts
