Additive Manufacturing/3D Printing
Additive manufacturing (AM) is the technological process of building a three-dimensional (3D) object, layer by layer, through a computer enabled design model.
AM enables rapid product development, improved product quality and reduced costs and time to market; it is continuing to grow thanks to its convenience and accessibility, which lead to reduced inventory carrying requirements. To realize its full potential, AM must rely on innovative additives that can enable new functions and help improve product quality and performance, as well as process efficiency.
Colloidal and composite silica particles
Dry fluffy powder that can be easily dispersed down to primary particles.
Fumed silica
Can impart key performance benefits for additive manufacturing across all technologies.
Specialty carbons
Can deliver desired pigmentation, resistivity and mechanical properties.
SLA is a leading technology for producing quick prototype parts, form and fit testing, and dental applications. It is one of the most accurate 3D printing processes, delivering excellent surface finish. However, post-printing processing is required to enhance deformation and breakage resistance in the finished products. Nonetheless, the mechanical properties of the SLA printed parts are often inferior to those in parts produced by injection molding. Our fumed silica offers the following functions:
- Enables improved mechanical properties
- Enables improved thermo-mechanical properties (higher Heat Deflection Temperature)
- Easily dispersible
- Offers viscosity control
Selective Laser Sintering (SLS) is a leading process for prototyping and functional testing of end-use plastic parts. SLS printed parts often have some micropores, with detrimental effect on mechanical properties. Our carbon black can enhance energy absorption during SLS printing to promote improved fusion. In addition, our fumed silica and treated colloidal silica offer the following benefits:
- Enables increased powder recyclability
- Enables improved powder flowability
- Enables improved mechanical properties
- Enables reduced print times
- Effective antiblocking agent
OTHER BENEFITS FOR AM PRINTED PARTS
Our specialty carbons contribute to the plastic molding process by promoting aesthetics or electrostatic discharge (ESD) in plastic parts. Our fumed silica provides improved handling on plastic films and mechanical properties in silicone molded parts. We solve problems by translating needs into particle attributes using application know-how as well as provide the following functions in the 3D printing process.
Black pigmentation
Specialty carbon enables electrical conductivity
Fumed silica enables improved filament handling and mechanical properties in fused deposition modeling (FDM) processes
