Radix™ Printable Dielectric
3D-Printable Dielectric Material for use on Fortify FLUX Series Printers
Radix™ Printable Dielectrics
are the industry’s rst low
loss DLP and sterolithography
(SLA) 3D-printable material.
By combining a low loss resin
system with the design freedom
and speed of DLP 3D-printing,
this technology enables the
scalable manufacturing of new
RF components that cannot
be made with traditional
manufacturing processes. The
printable materials leverage
the performance of DLP and
SLA printing processes to allow
antenna engineers to implement
new dielectric components in
applications such as SATComm
antenna lenses and volumetric
circuits for mmWave frequencies.
Radix Printable Dielectric also
enables the use of Gradient Index
(GRIN) dielectric components
with little added complexity.
The solid 2.8 dielectric constant
material has a dissipation factor
of 0.0043 at 10 GHz, and can be
used to create structures that
have a graded dielectric constant
in all three dimensions by means
of a varying density lattice. These
latticed structures provide even
lower dissipation factor and
weight when compared against
a similar part made with solid
materials.

Fortify’s FLUX series printers powered by a DLP (Digital Light Processing) engine, combine the scalability, resolution,
and surface quality of photopolymers with the performance expectations of traditional high performance polymers.
CKM (Continuous Kinetic Mixing), a proprietary subsystem built into the printers, enables printing of photopolymer
resins with uniformly distributed functional additives. The system ensures that particles stay uniformly suspended
instead of agglomerating or settling to the bottom of the vat. CKM allows for an expanded processing window
compared to other photopolymer DLP or SLA systems, processing much higher viscosity materials. Fortify partners
with Rogers Corporation and other global chemical companies to extend material properties and solve printability
challenges. www.3dfortify.com
