For me, December 2016 got mostly written off, for various personal reasons, and I was quite happy to see the back of it. Now January 2017 brings a more hopeful outlook! Apologies for the time-lapse with this post, but hopefully still interesting to some. HNY all. Onwards .......
Like me, many
visitors in attendance at Formnext in Frankfurt at the end of last year noted a strong emphasis on metal AM
— either in passing or in dedicated show reviews. Indeed, the metal AM
community did dominate the floor space physically at Formnext with vast stands inhabited
by the old metal, new metal and, of course, big metal players as highlighted in my previous post. There was also
compelling evidence of new metal partnerships (and acquisitions) as well as
metal material companies.
However
this belies the very real, powerful and, in my opinion, equally dominant
developments with plastic 3D printing and AM. A notable trend that emerged in the plastic AM sector through 2016 highlighted a focus on customised manufacturing. While
product development processes remain a central application for plastic additive
technologies there is a definite shift by some of the leading vendors towards
holistic manufacturing and serial production applications for additive
technologies.
Stratasys
unveiled the direction it is taking into manufacturing earlier in 2016 when
it showcased the 3D Robotic and 3D Composite Demonstrators — both developed
through industrial partnerships. Customer driven innovation is what it is all
about these days. This was central to Stratasys’ messaging at Formnext, along
with a new partnership announcement — with Siemens — the two companies are
definitely in a serious relationship. The synergy here is easy to see, and
Siemens is a massive organisation. Not as big as GE, but huge nonetheless. The
central premise is again about holistic manufacturing, whereby AM (Stratasys)
combined with intelligent automation (Siemens) and advanced robotics will prove
to be a game changer. The other big announcement from Stratasys was the
commercial release of GrabCAD Print, which is out of beta. The GrabCAD Print
software application is all about simplifying the front end of the 3D printing
process — consolidating the various (and laborious) steps in preparing a file
for print. This actually emerged as a theme at Formnext, many of the hardware
vendors are working on this for their proprietary systems.
There’s a
certain irony, or perhaps it is just natural evolution in the sector, as 3D Systems
is also focusing in on holistic manufacturing (with its Figure 4 concept) and
customer driven innovation. Indeed, the transition to manufacturing, “on a case
by case basis”, was front and centre for the company’s messaging at Formnext.
The Figure 4, eye-catching with its use of robotics, was getting a great deal
of attention. Although talking with Timothy Miller, while the focus is on
manufacturing, I am also picking up a dedicated push for medical applications
where 3D Systems has a very strong ecosystem approach through its software, scanning,
modelling and production tech; not to mention some very talented and
experienced people.
For me the
most eye-catching stand exhibit was on the EnvisionTec booth where the company
was demonstrating a new binder jetting system. Binder jetting is completely new
for Envisiontec, and the RAM123 system has been developed in cooperation with
Viridis and utilises a large robotic arm, with a proprietary 28” print head
attachment that lays down both the build material and the binder concurrently.
Undoubtedly Envsiontec has supplied funding to develop this system, although
there was a suggestion it had acquired Viridis, but that is unconfirmed.
Formnext
2016 was the first time anyone got to see a working MultiJetFusion system from HP.
It’s hard to overstate the difference it made to my understanding of the
process — and it is indeed impressive, particularly in combination with the
ancillary equipment that promotes safe material handling and automation. A tour
of the booth also highlighted where HP is going with this tech in terms of some
very clever embedded electronics that could potentially resolve traceability
issues in production. I even got to understand the mind set behind introducing
some of this tech so far in advanced of commercialisation. Not so much with the
main system — I think that was like normal bugs, but with the embedded
electronics the design software does not yet exist to support it — I was told,
by Ramon Pastor, that the CAD companies “are working on it.” I actually got a
similar story from Nano Dimension, when I talked to Simon Fried, the company’s
CBO.
Other
interesting non-metal highlights came from BigRep, Roboze and Roland DG. These
mostly centred around material developments and capabilities. BigRep, still
headquarted in Berlin, but with a shiny new office in Brooklyn, NY announced an
interesting cooperation with Kuhling & Kuhling. The resulting delta printer
is specialised for high temp printing of Polycarbonate. Roboze, meanwhile
demonstrated its robust system that is capable of printing PEEK and PEI. And UK
company Roland DG introduced a conceptual ceramics additive machine. In a now
familiar story arc, the development of this system was driven by applications,
notably from the dental industry. According to my source, the system is a while
away from commercialisation but very interesting nonetheless.
There were
also a couple of companies notable by their absence from Formnext, namely Mcor
Technologies and Carbon. Nothing sinister, I'm told, just calendar clashes!
This series of posts has, during writing, broken down via AM materials categories. That wasn't originally the intention — but I think it kind of reflects where we are in this industry right now. To follow in part three is some thoughts on the very interesting, albeit, early developments with ceramics.
