ment, and only initiates when ink is exposed to the body fluids,
providing an ample working time for the surgeon.
When the ink is combined with a collagenous substance containing
living cells, it enables in-situ fabrication of bone-like
tissues that may be suitable for bone tissue engineering applications,
disease modeling, drug screening, and in-situ reconstruction
of bone and osteochondral defects.

Rugged, Dependable Solutions
For Demanding Applications
esearchers combined additive manufacturing with conventional
compression molding to produce high-performance
thermoplastic composites reinforced with short carbon fibers.
The approach demonstrates the potential use of large-scale
multi-material preforms to create molded composites.
The researchers used ABS polymer, filled with carbon and
glass fibers, in three manufacturing processes: additive, extrusion
compression molding, and the combined approach of additive
and compression molding. The team analyzed mechanical
properties of the resulting composite samples.
The integrated process showed substantial improvement
in mechanical properties due to high fiber alignment and
reduced porosity, indicating that multi-materials can be deployed
for com posites in applications in aviation, transportation,
and defense.
Further research will include developing the system to be able
to use long or continuous carbon fibers for enhanced strength.
