Nylon FDM Material Offers Greater Strength
Stratasys has introduced a nylon material designed to offer greater resistance to breakage
and better impact strength than other fused deposition modeling (FDM) materials. Specifcally
engineered for the company's line of Fortus 3D production systems, FDM Nylon 12's elongation-at-break specifcation is said to surpass that of other 3D-printed nylon 12 materials
by as much as 100 percent. This can enable manufacturers in aerospace, automotive, home
appliance and consumer electronics industries to create durable parts that can stand up to
high vibration, repetitive stress or fatigue.
FDM Nylon 12 is available for the Fortus 360, 400 and 900 systems. It is initially being
offered in black and is paired with SR110, a new soluble support material that the company
says is optimized for the nylon material.

Technology
EnvisionTEC's Xede
3SP large-format 3D printer uses the company's scan, spin and selectively photocure (3SP)
technology to quickly produce accurate parts from
STL fles, regardless of geometric complexity.
According to the company, the surface quality of
the printed parts shows no signs of stairstepping
on the inner and outer surfaces.
The machine had been part of the company's
Perfactory family of 3D printers that use digital
light processing (DLP) technology. The new 3SP
approach, which allows for larger build sizes,
employs a multi-cavity laser diode with an orthogonal mirror spinning at 20,000 rpm. It can be
used to produce everything from concept models
to functional parts with minimal material waste.

14— AM Supplement
The SonicLayer 4000 from Fabrisonic LLC features the
company's patented ultrasonic additive manufacturing (UAM)
technology, which uses sound to weld together metals into
solid three-dimensional shapes.
Because this process uses solid state welding, it lends
itself to welding dissimilar metals, including aluminum, copper,
stainless steel and titanium. And, unlike a metal fusion process,
UAM avoids brittle inter-metallics that form during the combination of two or more metals, the company says. Periodic
machining operations help create further details on UAM-built
objects, including deep slots; hollow, latticed or honeycombed
internal structures; and other complex geometries.
The SonicLayer 4000 features a 9-kW welding head for
additively manufacturing the solid metal parts and a three-axis
CNC mill with a 25-hp, 8,000-rpm spindle for machining
them. The 4000R model also offers a fourth axis that rotates
underneath the traditional three-axis motion system. This
additional axis positions a cylindrical part under the welding
system and enables 3D printing of metal features on the OD of
a shaft, cylinder or pipe.
