Youth-driven culture

To keep pace with the expansion Roboze, currently a
company of 25 employees, will hire 40 new employees in 2018 and
a further 60 in 2019. Roboze say that the average age of its
employees is 30, with over half of employees dedicated to
research and development.

The facility has been designed with staff happiness as a
priority. Relaxation rooms and designated meeting rooms
have been purposefully created “to capture the youthful and
innovative characteristics that the Roboze team represents.”

New Roboze medical division

Roboze’s focus in recent years has been on the industrial
market. The company plans to allocate its expanding resources
to the creation of a new division dedicated to medical

Roboze will apply its materials expertise to
the growing market for

medical applications
of PEEK, a
bone-like polymer
used for 3D printing implants
. The company says it has
already laid the groundwork for six research projects for the
development of 3D printing materials with medical

Recently, Roboze has received regional approval for a
€1.3 million project for the design and fabrication of a 3D
bio-plotter, to be used in the 3D printing of medical

New offices, adapting to industry needs

Roboze is to open a new branch office in Chicago, where
applications engineers and marketing managers will work to
enhance the company’s reach in the U.S. market.

The company will start production in 2018 of the

ARGO 500
, their latest 3D printer. The
ARGO 500 is a large scale printer compatible with polymers such
as PEEK, Carbon PA, UTEM AM9085F and Carbon PEEK.

Roboze builds around 30 percent of its 3D printers’
components in house.

“Our ability to build in-house makes Roboze extremely
fast, and highly adaptable to rapidly changing industry

Roboze said “our machines are completely designed
[in-house]. We write the software language, design the user
interface, and manufacture our extrusion heads in-house. All
this know-how under one roof, allows us to respond quickly and
stay at the top of our industry when technologies or markets
change. Investing in production technologies also increases our
experience and opens up new opportunities. Our goal isn’t to
produce the most machines, but rather to produce the best
machines in the world.”

Dartmouth smart ink 3D prints, shrinks and transforms smart materials

A 3D printed, shrunken Arc de Triomphe represents the result of
the latest research undertaken by the Ke Functional Materials
 at Dartmouth College.

Focused on developing innovative materials for 3D and 4D
printing applications, the Ke Group’s most recent ink makes
objects that change size and color in reaction to external

Though still far from producing an end-use article, the study
lays important groundwork for scientists seeking to produce
smart materials capable of self-assembly,
and performing useful tasks in
medical research
, engineering and more.

Professor Chenfeng Ke, pricipal investigator of the Ke
Group, comments, “While many 3D-printed structures are
just shapes that don’t reflect the molecular properties of the
material, these inks bring functional molecules to the 3D
printing world,”

“This technique gives life to 3D-printed objects.”

Giving life to 3D printed objects

To make a shrinking, color changing Arc de Triomphe, the Ke
Group uses a
Direct Ink Writing
method of 3D printing. Like FDM/FFF
based techniques, an object is built up through the extrusion
of successive layers, the main difference is the feedstock, and
resulting operating temperature.

In the proof of concept experiment, a benchmark model of the
Arc was FDM/FFF 3D printed in ABS and a second Arc, matching
the scale of the ABS benchmark, was 3D printed in the lab’s
specially developed G1 hydrogel ink.

As visible from the picture below, Direct Ink Writing produces
a rough, yet discernible, structure of the Arc,
at 300-micron resolution.

Each stage of the Ke Group's shrinking 3D printed sample with ABS Arc de Triomphe for comparison. Image by Chenfeng KeEach stage of the
Ke Group’s shrinking 3D printed sample with ABS Arc de Triomphe
for comparison. Image by Chenfeng Ke

After air drying, and calcination (At a temperature of 700°C)
the G1 Arc shrinks to 1 percent of its original size, with
10 times the resolution.

While rudimentary, the technique represents a step-changing
possibility that could bring down the cost of industrial 3D
printers. “This process can use a $1,000 printer to print what
used to require a $100,000 printer,” explains Ke, adding that
the “technique is scalable, widely adaptable and can
dramatically reduce costs.”

The future of smart materials

In addition to shrinkage, models made using the G1 hydrogel ink
can can be tuned to change color by adding fluorescent markers
to the ink. The chameleon-like change is activated by shining a
light on the surface.

“This is something we’ve never seen before,” adds Ke, “Not only
can we 3D print objects, we can tell the molecules in those
objects to rearrange themselves at a level that is viewable by
the naked eye after printing,”

And, importantly,

“This development could unleash the great potential for the
development of smart materials.”

UK’s first additive manufacturing apprenticeship launching this September

This September, the Manufacturing Technology Centre
(MTC), based in the UK, will launch what are described as the
UK’s first additive manufacturing apprenticeships, with the
goal of addressing skills shortages within the industry.

The MTC is an independent research and technology
organisation, aiming to bridge the gap between academia and
industry. It was founded in 2010 by four institutions, The University of
, Loughborough
, The
University of Nottingham
, and TWI.

Apprenticeships address industry need

The MTC houses the UK’s
National Centre for Additive Manufacturing
develops industry ready additive manufacturing processes. It
also addresses barriers to the adoption of additive
technologies, and legislative and standardisation issues facing
the industry.

NCAM’s facilities and comprehensive range of AM
equipment, including 3D printers from EOS, Renishaw, Stratasys and HP,
should provide a valuable resource for the MTC’s

Martin Dury, the MTC’s Learning Design Manager, said
“While there are a number of additive training courses
currently available in the UK, these tend to be focused on
equipment use. The MTC is aiming to provide additive
manufacturing apprenticeships that will cover the whole range
of competences necessary for specific occupations. They will
also offer accredited curricula of short courses to enable the
up-skilling of existing staff.”

The MTC currently runs additive manufacturing courses, though
they are tailored to decision makers looking for insights into
the processes and design benefits of additive manufacturing.
The new apprenticeships offered by the MTC will seek to produce
a “pipeline of technicians fully skilled” to enter the
industry. Apprenticeships will be targeted at 16-19 year
old school leavers, and those in the industry wanting to boost
their skills.

Dury says “We have all the equipment and capabilities to
deliver first class, sector-wide and technology agnostic
programmes for apprentices or existing employees.”

“The manufacturing industry is crying out for this and we
will be able to make it available in a format which allows
people to learn while earning”

INTERVIEW: Terry Wohlers on the 2018 Wohlers Report, explosive growth in 3D printing

The Wohlers Report 2018 was published last week. As in
previous years, I caught up with Principal Author Terry Wohlers
to learn more.

The Wohlers Report is always eagerly awaited and regarded by
many as the definitive guide to our industry. The vast amount
of data provided has launched a thousand power-point
presentations, and makes Terry Wohlers one of the most
in-demand, and well respected analysts in the 3D printing

Terry Wohlers speaking at Formnext 2016. Photo by Michael Petch.Terry Wohlers speaking
at Formnext 2016. Photo by Michael Petch.

The 2018 report shows that overall the 3D printing
industry grew by 21% in the 2017/18 reporting period. This
figure is an increase on the 17.4% in worldwide revenues from
2016, and is edging closer to the 25.9% growth reported in

For 23 years Wohlers
has published this important report
covering the additive manufacturing landscape and the state of
the industrial 3D printing industry.

2018’s report contains a number of remarkable figures.
These include the fact a phenomenal number of metal 3D printers
were sold in 2017. According to the 2018 Wohlers Report, a
total of 1,768 metal additive manufacturing systems were
purchased in 2017. This is an increase of approximately 80% on
2016, when 983 industrial metal 3D printing systems were

The Wohlers Report 2018.The Wohlers Report 2018.

3D printing industry grew by $1.25 billion in 2017

The Wohlers Report also provides useful data on the
number of companies selling industrial additive manufacturing
systems, a total of 135 in 2017 compared to 97 in 2016.

The term ‘industrial AM system’ is defined in the report
as, “machines that sell for more than $5,000.”

To learn more about what drove a $1.25 billion expansion
in the 3D printing industry, and to get behind the headline
figures, I asked Terry Wohlers, Principal Consultant and
President of Wohlers Associates Inc. a few questions.

Wohlers Report 2018 metal AM systems. Chart via Wohlers Report 2018.Wohlers Report 2018 metal
AM systems. Chart via Wohlers Report 2018.

3D Printing Industry: The 80% increase in metal AM
systems on 2016 figures is a remarkable number. Can you tell us
anymore about what is driving this number? Is this a one-off or
will 2018 see a similar increase?

Terry Wohlers: Desktop Metal
sales, reported for the first time, contributed 20.2% of
the total. Some users of metal AM systems (i.e., metal powder
bed fusion) are beginning to hit a stride that requires more
capacity, so

they are buying multiple machines
. This
is much different than in the past when one or two machines
were sufficient for testing and qualification of the materials
and processes.

It’s impossible to know what the future holds, but
every indication suggests that 2018 will be another strong

16-year material sales growth trend in additive manufacturing. Chart via Wohlers Report 2017.16-year material sales
growth trend in additive manufacturing. Chart via Wohlers Report

3D Printing Industry: Likewise, the increase in
companies producing industrial AM systems is impressive. Are
there any specific factors behind this?

Terry Wohlers:
Many patents have expired
, so this has
been a factor. Some countries in Asia, such as China and India,
were slow to adopt AM in a serious way, but they are now
investing in it.

Many new system manufacturers are especially emerging
in China.

3D Printing Industry: You’ve mentioned in the
past, including at

Formnext 2017
, the need to lower
material costs. Do you see this as the key barrier to
widespread adoption of AM, or are there other specific barriers
the industry needs to address?

Terry Wohlers: Material pricing continues to be a
major obstacle to growth for production applications. The
problem will take care of itself over time, largely through
competition. Design for additive manufacturing and costs
associated with post-processing are also barriers to

3D Printing Industry:
Design for Additive Manufacturing

[DfAM]is a frequent theme in your presentations, and has
a dedicated section in the report. What are your thoughts about
how AM users are engaging with this topic and importantly
putting it into practice?

Terry Wohlers: It has been slow, mainly because
companies must make a commitment to using AM for production,
and doing the analysis is not trivial. This is especially true
when considering the cost implications of so many design

3D Printing Industry: What surprised you most
during the March/March period the new report covers?

Terry Wohlers: We were surprised by the rapid
growth in metal AM systems sales. Also, we were surprised by
the continued growth in the number of new manufacturers of
industrial AM systems.

It’s not an exaggeration to say we’re seeing explosive
growth with both.

The Wohlers Report 2018 has seventy-six co-authors and

Russian Academy of Sciences leads unprecedented high-resolution 3D printing research

Two-photon lithography
is a method of 3D printing that can
produce objects on a molecular scale. Valuable to the fields of
medical research, i.e.
devices for drug delivery
, tissue regeneration, chemical
& material synthesis, the technology warrants
deeper development
to help expand the possibilities of the
technology and lower the cost.

In a study led by a team at the Russian Academy of Sciences (RAS)
in Moscow, researchers have explored an “unprecedentedly
effective” method of high resolution 3D printing that
eradicates some of the shortcomings associated with existing

Laser control

The RAS high-resolution 3D printing method is based on vat
polymerization technology, where a light source is to solidify
a resin.

In two-photon lithrography, femtosecond lasers are used to
precisely cure the resin. Not only is the spot-to-spot process
time consuming, but the lasers work at high intensities, which
can damage materials, and the instruments are expensive.

Lasers in two-photonlithrography operate at the near-infrared
(NIR) phase of light. The RAS technique also uses NIR light but
at a lower intensity.  To make the most of the light’
potential energy and eradicate some of the shortcomings of the
femtosecond lasers as listed above the scientists add something
new to the mix.

Making macro and micrometer scale objects with

Upconverting nanoparticles (UCNPs) are made of two or more
photons that join together and emit more energy when exposed to
a light source. In the RAS study, UCNPs are added to the
photo curable resin mix.

Under a ray of NIR light, the UCNPs form to emit a UV light.
This light, in turn, polymerizes surrounding material to make a

The success of the process is that it high-resolution objects
are made using a relatively low-intensity NIR light source.
Photoplymerization also occurs deeper within the resin vat,
giving the technique the potential to 3D print within
biological tissues.

In-situ 3D bioprinting

The overall conclusion of the study is an “unprecedentedly
high conversion efficiency in the UV range,” successfully
demonstrating NIR-induced polymerization for macro and
micrometer scale objects.

According to Kirill Khaydukov
, co-author of the RAS study,
“This idea can be used for biomedical purposes, including
tissue engineering, and replacing damaged parts of organs
and tissue with the help of various polymer

In addition;

“We expect that our technology will allow us to create
designs with the right sizes and properties
inside living tissue to repair damage.”

INTERVIEW: Maritime 3D printing with RAMLAB and Semcorp Marine

3D printing for the maritime and energy industries is the
focus of
NAMIC’s 5th additive
manufacturing summit later this month.

Taking place in Singapore, the Maritime
and Energy AM Summit
is organized by the
country’s National Additive Manufacturing Innovation Cluster
(NAMIC), an organization focused on developing a collaborative
and innovative ecosystem for additive manufacturing.

NAMIC 5th AM SummitThe 5th NAMIC AM Summit

At the event 3D printing experts will gather to discuss
operationalising AM, how 3D printing is revolutionising the
energy industry, the future of advanced manufacturing and other
related topics.

I caught up with two of the experts presenting work at
the NAMIC AM summit to learn more.

3D printing for the maritime sector

3D Printing Industry: How is you enterprise currently using
3D printing for the marine industry?

Simon Kuik, Sembcorp Marine: Since 2000, Sembcorp
Marine has digitised our design process by incorporating
3D-design. Besides visualisation, the data are translated for
cost-effective and productive numeric-control component
manufacturing, assembly and integration. We also adopted
digital rapid prototyping for component design and model
making. Future additive manufacturing applications will focus
on locally-built metallic components and machine parts.

Sembcorp Marine is also working with industry partners
such as DNV GL to develop a quick and simple certification
method for the 3D-printing process and to evaluate the
technical feasibility of printing parts for repairs and
newbuilds. We foresee that the local offshore and marine
3D-printing ecosystem will take 3-5 years to mature.

Vincent Wegener, RAMLAB: RAMLAB provides its
partners easy access to an open innovation ecosystem in which
the necessary resources and research on additive manufacturing
are shared to the benefit of all. Close collaboration on joint
projects accelerates the development and dissemination of
relevant knowledge at a rate unattainable by a company
operating on its own.

3D Printing Industry: What applications of 3D printing for
maritime do you see becoming possible in the next 5 years?

Simon Kuik, Sembcorp Marine: Short-term
applications will mainly revolve around one-off printing or
printing low quantities of small and expensive machine parts
that have a long lead-time and are non-load-bearing. These can
be new parts, or existing ones to be repaired.

Sembcorp Marine’s immediate focus is also to develop the
3D-printing value chain and supply chain; certification by
classification societies; and customer acceptance. In the long
term, the cost of 3D-printing should be made affordable once
the technology matures and when the supply side is well
established. More parts can then be economically

Vincent Wegener, RAMLAB: In 2017 RAMLAB unveiled
the world’s first class approved 3D printed ship’s propeller,
the WAAMpeller. The ground-breaking success was the result of a
close collaboration between RAMLAB, Promarin, Autodesk, Bureau
Veritas and Damen Shipyards.

We will see more WAAM applications that are larger,
topology optimised and have unique material properties the
coming years.

process. Photo via RAMLAB.

3D Printing Industry: What are some of the challenges of
using 3D printing in the Maritime sector, how do you see these
being overcome?

Simon Kuik, Sembcorp Marine: Other than challenges
mentioned earlier (e.g. supply chain development, high costs of
3D-printing machines and metal powders) which can be made more
feasible with the maturing of the 3D-printing market, there are
also IP issues to be considered when 3D-printing OEM parts.
This is a more challenging issue in regard to getting
acceptance from customers and users for load-bearing and
critical function parts.

However, other industries that are early-adopters of
3D-printing have addressed IP issues successfully and we expect
similar standards to be advised for the O&M industry. By
applying 3D-printing to critical function parts, Sembcorp
Marine helps add value to the 3D-printing process and creates
confidence in this application.

Vincent Wegener, RAMLAB: Certification is one of
the most challenging parts of 3D printing in the maritime
sector. With the WAAMpeller project we have shown that it is
possible to certify a WAAM part if you can monitor and control
the material properties at all times.

3D Printing Industry: How would you characterise the
importance of 3D printing for Sembcorp Marine and RAMLAB?

Vincent Wegener, RAMLAB: RAMLAB’s mission is to
accelerate the adoption of additive manufacturing technology to
realise the vision to manufacture large certified metal parts
on demand. So, yes quite important.

Simon Kuik, Sembcorp Marine: 3D-printing is
important for improving Sembcorp Marine’s business:
productivity, flexibility in customising designs, as well as
on-demand, on-site manufacturing. With 3-D printing, lighter,
stronger and safer products can be manufactured in a more
responsive manner, while reducing leading-time and material

Keeping abreast of up-to-date skill-sets and knowledge is
required. Relevant jobs will be restructured to higher-value
work such as 3D-design, 3D-printer operation and 3D-printing
quality control methods.

In developing our advanced and state-of-the-art
infrastructure for the new-generation, smart and sustainable
Tuas Boulevard Yard, Sembcorp Marine will invest in relevant
3D-printing facilities following the successful development and
test-bedding of this technology.

Singapore is one of the pioneers in 3D-printing
technology development and adoption. Sembcorp Marine aspires to
contribute to the building of the local ecosystem and
expediting the 3D-printing technology development through
programmes such as the Sembcorp Marine-DNV GL-NAMIC joint
industry collaboration.

U.S. Air Force advancing hypersonic flight vehicles with 3D printed ceramics

The U.S. Air Force is advancing the development of
hypersonic flight vehicles with 3D printed ceramics.

The research into applications for the 3D printed
ceramic, silicon oxycarbide (SiOC), is conducted under a
Collaborative Research and Development – Material Transfer
Agreement (CRADA-MTA), between the US 
Air Force Research
 (AFRL) Aerospace Systems
Directorate and
, a research center owned
General Motors
and Boeing.

The project continues the development of research into 3D printed
at HRL, first reported by 3D Printing Industry in

Geometric complexity achieved with 3D printing

Scientists at the Aerospace Systems Directorate (ASD)
searching for new thermocouple radiation shields became
interested in the HRL produced SiOC because of its potential
for hypersonic flight. Specifically, the refractory qualities
of SiOC, the ability to maintain strength and form at high
temperatures, and the geometric complexity offered by 3D
printing have a wide range of Air Force applications.

The SiOC was 3D printed in a pre-ceramic resin. After
fabrication, the resin was heat treated to produce a fully
ceramic component. Jamie Szmodis, an ASD hypersonic research
“If a material can withstand temperatures [of]–
roughly 3,200 degrees Fahrenheit – it could be used for
hypersonic aircraft engine components like struts or flame

Viable hypersonic aircraft, flying at speeds over 4,000
miles per hour, would enable faster military response times,
faster long-range missiles, and potentially decrease travel
times for military and commercial airliners. 

Collaborators, not customers

CRADA-MTA agreements are made between federal and private
parties for research and the exchange of proprietary material.
The agreement protects the private company, HRL, allowing them
to file patents and retain patent rights for inventions
developed as part of the CRADA-MTA, whilst keeping research
confidential for up to five years.

According to Szmodis, the agreement was crucial “Without
the material transfer agreement, we would have purchased the
samples to test them. We would have been a customer, as opposed
to a collaborator. With the agreement we are able to provide
test results to HRL and provide feedback that is valuable to
both parties.”

ASD has already tested five thermocouple radiation
shields and 15 sample cylinders fabricated from SiOC, provided
by HRL.

Laboratory’s (AFRL) directorates were assembled to test the HRL
produced components. Led by Dr Matthew Dickerson, a Materials
Research Engineer, scientists from the AFRL’s Materials and
Manufacturing Directorate, Structural Materials Division and
Composite Branch conducted materials analysis and heat

The ASD, with the Aerospace Vehicle Division and
Structural Validation Branch scientists carried out mechanical
analysis tests at temperatures between 500-3,500 degrees

Results were published in a report given to HRL in March.
Dr Tobias Schaedler, a senior researcher at HRL, said:

“The extreme temperature testing that AFRL performed
revealed the limits of our new material and challenged us to
improve it.”

Last year, Boeing and Aerojet Rocktdyne
were selected by The Defense Advance Research Projects
Agency (DARPA) to complete

design work for the XS-1 hypersonic
. The project is aiming to enable
more cost-effective satellite launches.

A research team at Imperial College
established the
highest ever melting point for refractory
at 4,000 degrees Celsius.

US Navy metal 3D printing for battleships

The U.S. Office of Naval
(ONR) is bringing the Navy closer to 3D printing
metal parts for vital air, ground and sea platforms.

The ONR has awarded Concurrent
Technologies Corporation
(CTC) a two year $2.6 million
contract, with a $3.8 million option, to ensure the
manufacturability of metal 3D printed parts.

The contract is part of the Quality Metal Additive
Manufacturing (Quality MADE) program, an ONR initiative to
enable cost-effective, on-demand production of 3D printed metal
parts, for use in maintenance, repair and overhaul (MRO).

The global market for naval MRO has been predicted by
Credence Research
to grow at a rate of 8.8 percent annually
between 2017-2025.

Naval MRO needs met by 3D printing

CTC will fabricate components using laser powder-bed
fusion metal 3D printing in collaboration with project team
SLM Solutions
, MRL Materials Resources
, the University of
, and America

Last year, Vice Chief of Naval Operations Admiral William
Moran said the Navy is facing a “downward readiness spiral” as
a result of years of high demand of naval forces and funding
cuts. CTC and its project team members will be looking to
address this by rapidly developing metal 3D printed components
for MRO.

According to the ONR, “Aging Naval platforms are being
challenged by dwindling traditional sources of supply. In
response to this need, the Naval Warfare Centers, maintenance
depots, and FRCs plan to use additive manufacturing to produce
small quantities of out-of-production or long lead-time
metallic components.”

CTC CEO, Edward J. Sheehan Jr., concurred saying “personnel and
aging equipment are stretched thin amid years of war, statutory
budget caps and temporary workarounds, end-strength cuts, and
Congress passing continuing resolutions.

In response to this need, Concurrent Technologies Corporation
and its integrated project team members are providing new
technology that can address the short and long-term challenge
of replacing aging or broken parts literally on site.”

The Navy’s commitment to 3D printing

The contract furthers the U.S. Navy’s commitment to 3D
printing. The Navy recently partnered with additive
manufacturing data collection and software development
Senvol. The
partnership will develop a

machine learning program for the expedited creation of 3D
printed parts

Stratasys and SIA
Engineering Company
are opening a
service center in Singapore
to “advance the use of additive
manufacturing” to solve the “unique challenges of the MRO

printing. Spanish ship builder

Xact Metal releases sub-$100k and high precision metal 3D printers

Metal 3D printer manufacturing startup Xact Metal has released two new
powder-bed fusion based (PBF) systems: the XM200S and the

“The XM200S,” according to company CEO Juan Mario Gomez, “is
ideal for printing of small parts where high performance
applications and print speed are critical.” The XM200C, on the
other hand, “makes metal powder-bed fusion available for
universities, labs and smallto-medium businesses who need
prototyping, casting, tooling and printing of small parts, and
who could not afford these systems in the past.”

Both systems are updates of the original XM200 system,
previewed by 3D Printing Industry
at RAPID + TCT 2017, and
aim to serve aerospace, defense, automotive and healthcare

Low-cost PBF

Xact Metal PBF technology is built on a patent-pending

Xact Core™
system. A simplified laser-direction system,
Xact Core™ delivers cost savings to the customer in the overall
price of the system.

“Making metal powder-bed fusion less expensive requires
innovation,” explains Xact Metal CTO Matt Woods. The Xact Core™
system delivers these savings as “a high-speed gantry system
platform that uses light, simple mirrors to move quickly and
consistently above the powder bed on an X-Y axis,”

“In addition,” explains Woods, “the Xact Core technology avoids
the use of complex rotating galvanometer mirrors and F-theta
lenses, maintains a constant laser angle across the whole build
plate, and provides a simplified gas flow over the powder bed.”

Both new systems from Xact Metal have this technology at the

PBF for SMEs

The smaller (and cheaper) of the two systems, the XM200C has a
build volume of 2048 cc³ (127 x 127 x 125 mm), and
occupies 610 x 610 x 1,295 mm³ (W x D x H) of space.

The small footprint and competitive price tag ($80,000 for
metal 3D printing) makes the XM200C Xact Metal’s solution for
researchers and SMEs.

Current powder options for the system include marine grade 316L
stainless steel, super alloys like Inconel 718, cobalt chrome
and bronze. It also designed in a open architecture, enabling
researchers to develop and implement their own materials and 3D
printing parameters.

High-caliber metal 3D printing

The XM200S is Xact’s first high-caliber 3D metal printer, with
additional features for the assured quality its products.

According to Woods, “Precision digital optical systems” in the
XM200S “provide active thermal drift compensation” eliminating
downtime caused by machine warm-up and minimizing “longterm
drift during printing operations.”

A patent-pending, bulb-shaped recoater improves the way powder
is spread and compacted in the build chamber. And, “24-bit
command resolution gives industry leading
positional accuracy.”

The XM200S’ build volume matches that in the
XM200C (127x127x125 mm), and it is priced
at $130,000.

Coming soon

Xact Metal is now accepting orders for the XM200C and the
XM200S systems. Shipments of the 200C will start June 2018, and
the 200S will begin September 2018.

The company will also be displaying the new systems
at RAPID + TCT 2018, April 23 – 26.
