3D printing news Sliced HP, Carbon, Proto Labs, Jeju National University

Are graphene seal whiskers the future of smart sensors? How can
you make new 3D printer materials using light? What can you do
to improve the strength and appearance of low-cost 3D printed
parts?

All these questions and more, from adidas, Siemens, CollPlant, Proto Labs and South
Korea, answered in today’s edition of Sliced 3D printing news
digest.

Material reinforcement

Nanoparticle experiments at the Institute for Basic Science
in Ulsan, South Korea, has yielded some “cool” results in the
way materials are made. Using light, magnetism and
electrostatics, the team were able to make combination
molecules that could lead to a new breed of tunable 3D printer
inks – following a  “Depending on what you make the
nanoparticles from the surfactants can be responsive to a range
of fields – magnetic, light, electrostatic,” explains Bartosz
Grzybowski.

“I am not sure how all these properties could be combined
into one molecule by traditional syntheses. With nanoscience
this becomes relatively trivial – we initially just toyed
with stuff and it turned out something cool emerged.”

The supporting paper, “Systems of
mechanized and reactive droplets powered by multi-responsive
surfactants”
can be read online in nature. Also
see our article on
colloidal self-assembly
for more research related to this
field.

In another, larger-scale, material development Proto Labs has launched
metal plating services for SLA and SLS 3D printed parts.The
service is intended to improve the finish aesthetic and
strength of low-cost 3D printed parts.

Daniel Cohn, General Manager of Proto Labs Germany, comments,
“We are continually evolving our capabilities to ensure we meet
the demands of our customers […] Now, with plating technology
and operational expertise in-house, we can manufacture plated
parts with increased capabilities that will support product
testing and project progression even further.”

Planting the seeds of development – CollPlant, Siemens,
Nano Dimension, HP, GE, Carbon

David Tsur has been appointed the position of chairman of the
board at 3D
bioprinter materials producer CollPlant
. Predating his
position at CollPlant, Tsur was Founder and CEO of Kamada
Ltd. (TLV:KMDA), a developer of biopharmaceutical
treatments for rare, orphan diseases. In this role, Tsur
promises to “continue
to pursue strategic joint ventures
” for the company in the
2018-2019 period.

Adding to an existing workforce of around 4,500 scientists and
engineers in China, Siemens PLM Software Company has unveiled
plans to build an “Industry 4.0” intelligent manufacturing
innovation center in Taiyuan.

A “leading research institute from Hong Kong” has become the
latest customer of the Nano Dimension
DragonFly 2020 Pro PCB 3D printer
. Of the territory’s
listed institutes, the system is most likely in use at either a
medical research facility, or the Hong Kong Applied Science and
Technology Research Institute
(ASTRI).

HP has made two new commitments to advance the adoption of
Multi Jet Fusion (MJF) is South, and South East Asia. HP MJF 3D
printing solutions are now commercially available in India and,
at a conference earlier this week, the company confirmed that
it will leverage its 3D printing expertise to help shape the
digital future of Vietnam.

The
money GE Additive/GE Capital gave to Roush
has been
used to purchase a Concept Laser Xline 2000R additive
manufacturing system. The Michigan-headquartered high value
engineering company will use the machine for bespoke,
large-scale production of parts like engine blocks.

Reinforcing its
high-profile Futurecraft 4D partnership with adidas
, Carbon
has added Eric Liedtke, Executive Board Member of adidas AG, to
its own board of directors. Liedtke has a BA in journalism from
the University of
Wisconsin
, and has been working in line
management/marketing for adidas since 1994.

Probing innovations

Boston-based studio Catalano Design caught our
eye this week by combing 3D printed with plywood. Approached by
HIFIMAN to create their flagship headphone product, lead
designer Carol Catalano directed an investigation of how wood
can be directly integrated in the 3D printing process. The
effects are demonstrated in a series of designs where plastic
appears to “grow” in and around much more organic planks. “This
opens up a whole realm of possibilities for creating expressive
printed forms,”
says Catalano
.

“Imagine a laminated wood seat with an array of mushroom
forms placed selectively for ergonomic comfort. Could this
replace traditional fabric upholstery?”

Seal whiskers have inspired new, multimaterial 3D printed
sensor research at Jeju
National University
in South Korea. The vortex-sensitive
whiskers are made from a mixture of polyurethane (PU) and
graphene. Full details of the process can be found under
“Fully
3D Printed Multi-Material Soft Bio-Inspired Whisker Sensor for
Underwater-Induced Vortex Detection”
in Soft
Robotics 
journal.

Samantha Snabes, founder of re:3D, has won a prize of $1
million to help develop her company’s “human-size”
industrial FFF 3D printers. The top-prize fund was granted to
Snabes by WeWork
co-working and office space providers in the first WeWork
Creator Awards.

In other accolades Nina Hoff, CEO of
3D printed food company byFlow
, has been deemed one of “the
5 most talented Women in Tech in the Netherlands” by
the Technionista Awards.
