3D Printed Street Furniture Made from Plastic Waste

3D printed benches are now bring created from plastic waste, as
part of Amsterdam’s ‘Print Your City’ initiative. This program
aims to transform plastic waste into trendy street furniture,
reducing annual waste.

Plastic: A growing problem

Currently, the average person in Amsterdam produces 23kg of
plastic waste per year. This is an alarming figure, and so
Rotterdam-based design studio, ‘The New Raw’, decided to take
action. With this goal in mind, The New Raw decided to use this
awste to create benches for Amsterdam. Co-founder Panos Sakka
said “Plastic packaging is everywhere and has an important
design flaw: it was designed to last forever when it is only
used for a few seconds and then thrown away very
easily. It follows a linear production process, from use
to disposal. We want to turn this linear process into a
loop that we could close in order to create new products from
waste.”

The Benches

The New Raw is part of a circular economy project where 3D
printing is used to produce environmentally friendly objects.
Other companies are involved in similar ventures, such as
OWA
3D
 who have produced a recycled and recyclable
filament. This project however involves creating benches. Each
bench weight 50kg, is 150cm long and 80cm wide, and can fit up
to 4 people. Its rounded shape means it rocks, an attempt to
get people to interact with each other to co-ordinate to find a
balance.the new raw

The New Raw use an Aectual to create the benches. It prints
from plastic pellets from city waste. Each bench is
customisable in its shape and size, and a logo or message can
be added to the benches. The city hopes this will encourage
people to waste less, and become more respectful of the
environment. You can find the whole story of the 3D printed
benches in the video below:

This initiative is great not only because it transforms waste
into something useful, but it inspires more to try and do the
same. Recycling isn’t typically the most exciting of
conversations, so transforming waste into a colourful, trendy
piece of furniture may help shake the stigma, and inspire more
people to take it more seriously.

3D Printing makes Stainless Steel 3X Stronger!

When you think of 3D printing, naturally you think of plastics.
However, there is a growing trend towards using metals as a 3D
printing material. The visibility of 3D printing metal has
grown further recently as HP
have announced plans to enter the 3D printing metal market

next year.

Stainless Steel

Usually, if you continue to harden steel you lose ductility.
This can lead to substances deforming, and may break. However
laser sintering, a 3D printing technology, may offer a solution
to this. The best 3D printing technology for metal is currently
laser sintering. Laser sintering uses melted metal powder,
fusing it to create intricate pieces. The problem however is
that this struggles to print the microstructures necessary for
truly resilient pieces.

Metal 3D printed at Airbus

A Californian Lawrence Livermore National Laboratory (LLNL)
research team proved metal products are significantly improved
with 3D printing. In collaboration with engineers from the Ames
National Laboratory, the Georgia Institute of Technology, and
Oregon State University, they managed to print a low-carbon
316L steel grade strong enough to be used in the military. This
new method means 316L steel can be created with a standard
printer, controlling heat and fusion to prevent the material
becoming porous.

“This microstructure we have developed breaks the traditional
force-ductility dilemma,” said LLNL materials scientist and
lead author Morris Wang. “If you want to make steel
stronger, but you lose ductility; you can not have
both. But with 3D printing, we can move that limit
further.”

Engineers experimented with steel printing using various laser
powders and thin metal plates. As a result, the strength
of stainless steel tripled under certain conditions – a
surprise even to the scientists.

What impact can this have on businesses?

It is too early to know how much of an impact this will have in
the short-term. This is a very promising discovery, however. As
it becomes possible to 3D print harder and more useful
materials, we will likely see it become a more widely used
technology.

voxeljet Continues Materials and Systems Development for High Productivity 3D Printing







During the first day
of formnext 2017
, Germany-based voxeljet presented its newest
3D printing system in a well-attended press conference as its
first proprietary High
Speed Sintering machine
was officially unveiled. Designed
to complement the company’s portfolio of binder jetting
technologies and advance 3D printing toward realizable
production applications, High Speed Sintering (HSS) drew quite
a crowd to the new VX200 HSS 3D printer. Additionally new for
the company was the introduction of a modified version of
its existing PolyPor processes used for making investment
casting patterns with PolyPor C2 (PPC²),
an advanced PMMA material process
for plastic 3D printing.
The company took the opportunity as well to elaborate on views
toward materials development, partnerships, facilities, and
vision.

“We are wide open for new materials; the purpose is to
develop new materials, our own material sets,” Tobias King,
the company’s Director Marketing & Applications,
explained. “We thought it was a good idea to present [the
VX200 HSS] here first before, in a year or so, a production
system.”

King noted that the company has begun work with PA-12, and is
working with partner Evonik toward the
development of a TPU material. He continued, noting that the
system has been set up in the company’s UK facility, where the
team find it “relatively easy to operate.” The forthcoming
production system based on this technology will, he said, “be
bigger and faster.”

“This is a similar process to HP — the big difference is we
have no detailing agent. There is one ink only; heat
management means there is no need for that agent. This is
laying down a powder, which is different from XJet; they are
not the competition,” King said of market comparisons being
made.

Advantages to voxeljet’s system include resolution (noted as
being 600 DPI) and geometric freedom, as King and CEO Dr. Ingo
Ederer noted. Said to combine the benefits of binder jetting
and selective laser sintering (SLS) technologies, HSS
additionally brings open materials capabilities. The VX200
system can work with different types of powder, with an average
grain size of 30 – 70 µm, for layer thicknesses varying
between 80 and 100 µm.

Featured at the voxeljet booth was UK-based chemical giant
Johnson Matthey, which has
been increasing its focus on — and
its presence in
— ceramics 3D printing. The two companies
are collaborating
on further development of ceramic binder jetting
, with an
eye toward a larger-scale future for developments. Johnson
Matthey (JM) began its work in this area with development of
next-generation catalytic solutions and is now working in
applications ranging from electrical insulating to aerospace to
medical.

So much information was presented during the press conference
that I came back the next day to find out more directly from
voxeljet Managing Director James Reeves. We started from the
beginning:

“voxeljet was established in 1999, which is quite well
established for a 3D printing company,” Reeves told me.

Looking toward the company’s well-known work with binder
jetting technologies, we discussed applications in investment
casting
. Materials play a big role, of course, in
considerations here, and voxeljet technologies can work with
materials from sand — “This is the same for foundries as they’d
get otherwise; here it just happens to be 3D printed” — to more
recent work with PMMA. Further keeping materials familiar to
users, Reeves noted that HSS can use Nylon 12, a powder
familiar to those working with SLS 3D printing technologies,
and allowing for users to “compare like for like.”

“HSS is a licensed technology, adding to our knowledge of
binder jetting,” Reeves said. “The VX200 is an R&D
machine. We are collaborating now on materials. Once we have
the production system, this will be open as well — truly open
materials.”


James Reeves, Managing Director, voxeljet

The company is keeping focused to its areas of expertise,
which, while expanding, are targeted. Reeves noted that
voxeljet is “not looking to take the whole market in terms of
providing materials and machines.” Working at an intentional,
steady pace toward development of its production machine,
voxeljet is keen to underscore the R&D nature of the VX200
HSS system.

“For us, the VX200 is a toy meant for R&D; compare it to
the huge 800 system. This system is really good for a
development company; it takes a thermal image every layer, so
you can change parameters as needed as you go. It all helps
in application and material development,” Reeves explained.

“The feedback we expect will help for production development.
It’s what you would expect from voxeljet: high productivity
meant for factories, not just labs.”


Returning to the
market comparisons raised previously, Reeves noted that “The
big question is: how different is this from HP’s technology?”
Referencing Multi
Jet Fusion technology
, HP’s proprietary 3D printing
technology in its Jet Fusion systems, Reeves acknowledged that,
yes, “It is similar to MJF.” The process using infrared is
similar, as is the start with Nylon 12 material, which was the
first to be available for use on MJF systems. Notably,
Evonik has also been a collaborative materials partner for both
companies.  However, HSS is distinct from MJF in several
technological matters, such as the lack of detailing agent
previously noted, as well as in the approach
each company is taking to market. While HP is known for its
open materials system, powders for use in Jet Fusion 3D
printers should still be certified by HP through a step-by-step
process
including approval from HP’s labs. When voxeljet
says ‘open materials,’ they mean it much more broadly. Further
differentiating factors lie in the companies’ approaches to
market, as voxeljet is not currently looking to sell production
machines.

“We are looking for collaborators, not customers,” Reeves
told me. “We’re very keen to speak to end users to inform
development. The end game would be to take on SLS, and
eventually injection molding.”

As voxeljet continues to reach toward its ambitious goals in
production, keeping that end game in sight is important for
building both process and strategy. The automotive industry
represents an important vertical for voxeljet’s technology, and
a target for production volumes via 3D printing.

“I think we will be one of the first to reach production
volume for automotive, starting with sand, and eventually
with HSS,” Reeves explained.

“We’re keen to talk to automotive; not just their additive
manufacturing teams, but their manufacturing departments. We
want to find out what they need, what their actual throughput
is, what their real needs are. We’re not just trying to sell
machines, we’re trying to meet needs.”

At formnext, the voxeljet booth was regularly packed with
intrigued visitors. There was “a lot of interest,” Reeves said,
in HSS, work with PMMA, and ceramics work with Johnson Matthey.

“We have this core competence working with different powders.
Johnson Matthey’s powder is very hard to feed. It doesn’t
flow well — you can make a snowball out of it — and we’ve
made it work reliably,” he said.


Building on its
years of experience, voxeljet is looking to enhance aspects of
working with difficult powders, looking at powder feeding,
post-processing, and granule size; “These are things we’ve done
for years,” Reeves said of the team’s expertise.

“We can process 15 tons of material. We know how to do
production volumes. We have eight and a half million liters
per year installed volume, with a growth rate seeing interest
rise massively,” he noted.

Looking ahead, Reeves said that it is definitely production in
sight for ongoing technology developments — a theme
running through the whole of this year’s formnext
as
hardware,
software,
and
materials
suppliers alike all turn toward end-use
applications.

“Customers are coming forward wanting less R&D, more
production,” Reeves told me. “We think production HSS will
really do well.”

Ethereal Machines Wins CES Innovation Award for 5-Axis 3D Printer/CNC Machine Hybrid







Already, CES 2018 is only a little over a
month away. It’s getting so close, in fact, that the CES
Innovation Award recipients are being named. The Innovation
Awards honor what CES describes as “outstanding product design
and engineering” in new consumer technology, and they’re highly
coveted every year as a stamp of excellence. In the 3D Printing
category this year, the award goes to Ethereal Machines, a
Bengaluru-based company gaining attention for its 5-axis 3D
printer/CNC machine hybrid, the Ethereal Halo.

A typical 3D printer prints on three axes: X, Y and Z. With a
5-axis 3D printer – also sometimes called a 5D printer – the
movement of the build platform actually creates two additional
axes. This results in more design flexibility, more complex
parts, and greater part strength. The Ethereal Halo is the
first 5-axis machine Ethereal Machines has designed; the
company began by manufacturing standard 3-axis machines until
it decided to challenge itself – not only by creating a 5-axis
machine, but by making it both a 3D printer and a CNC machine.

“All our earlier products were 3-axis machines,” said Kaushik
Mudda, one of the founders of Ethereal Machines. “After
building a sustainable business we wanted to up the ante to
make a desktop scale 5-axis CNC machine. The existing ones
were all really huge, and really costly, so we thought this
was a good challenge. And we didn’t realise that a bunch
of mechanical engineers like us wouldn’t suffice, so we had
to bring in designers, electrical engineers, coders, and so
on. But then we had the idea of let’s delve into additive
manufacturing. So once we had the 5-axis CNC, from mechanical
engineering to the proprietary code that’s require to print
with it, we just started toying with the idea of ‘what will
happen if I move an additive head onto this machine?’ and
from there we got to the Halo.”


The disadvantage of typical FDM 3D printing, Mudda explained,
is that you’re essentially just stacking layers on top of each
other, and if you put enough force on the Z axis the part is
going to break. The moving bed of a 5-axis 3D printer, however,
allows the machine to print from different angles, building an
object that’s sturdier than stacked layers. It also allows for
geometries that aren’t possible with conventional FDM 3D
printers.

“So imagine something like a concave shaped cap – it’s
impossible to make with a regular 3D printer, because you’d
need to build a lot of filler, and supports,” he continued.
“But with a 5-axis since the bed itself is moving, it gives
me the freedom to print however I want, [make]that kind of
structure. Or a cylinder with fan blades, how do you do that
with a regular 3D printer?”


By
combining both subtractive and additive manufacturing
in
one machine, even more flexibility is enabled. Entire products
can be built on the same machine, in the same build, with the
3D printer and the CNC router working together – the user can
easily switch between them at any time. The machine is
desktop-sized, too, and prints with a wide range of 3D printing
materials. It can also machine a large variety of materials,
meaning that complex multi-material objects can be built, even
things like wearable electronics, said Mudda.

Winning the CES Innovation Award came as a surprise, and has
gotten Ethereal Machines some attention. Recently the company
signed a contract with the University of Sheffield,
where students will use the Halo for aerospace and aviation
applications. It’s a busy time for Ethereal Machines, which is
now at the Global
Entrepreneurship Summit
beginning in Hyderabad today. And
of course, there are preparations for CES, which is taking
place in Las Vegas from January 9-12.

Teknodizayn Introduces Injection Molding-Inspired LOOP Industrial Continuous 3D Printing Platform







We first heard
about Teknodizayn, a
major international distributor of industrial and
professional grade 3D printers and scanners based out of
Turkey, last year, when the founder of AVSAR Aesthetic Surgery
Clinic
 in Istanbul was inspired
by one of the company’s 3D scanning and printing
demonstrations
to purchase an Artec
Eva 
handheld 3D scanner from Teknodizayn
partner Artec
3D
 in order to give his plastic surgery patients a
better idea of what their faces would look like post-surgery.

Now, we’re pleased to learn more about this Turkish company, as
it introduced the LOOP
3D Continuous 3D Printing Platform
at
formnext
earlier this month in Frankfurt.


“In Turkish market the 3d printers became a point of
attraction over last 2-3 years and the industry started
to realise that a 3d printer it is not a luxury anymore but a
necessity to keep up with the global
industry,” Teknodizayn CEO Mehmet Erkan Ustaoğlu
told 3DPrint.com when asked how 3D printing technology was
growing in the Turkish market.

“As the consumer 3d printer market in Turkey already has many
customers, the industrial market is still hungry for it and
growing day by day in parallel with latest technological
developments of 3d printers.”


The LOOP 3D printer
represents a unique approach to continuous 3D printing – it
uses a patent-pending automated system, inspired by the
injection molding process, to rapidly remove parts. The
company, which prides itself on its R&D activities,
unveiled its prototype system to the world for the first time
at formnext, and the LOOP platform could, according
to Teknodizayn, “define new standards for batch
production.”

“We have been working in both subtractive and additive
manufacturing business for long years and we experienced the
imperfections of these machines from first hand. It was
always a burden that when a build finishes an operator
intervention was always needed to take the part out, clean
the build area and start the new build. It was especially a
problem when the builds end in irrelevant hours like in the
middle of the night so that only options were waiting until
morning to start the next build or paying extra for another
operators night shift which is mostly the case not to lose
time,” Ustaoğlu told us.

“So we thought that we shall find a way to eliminate that
need and to overcome this problem so this is when the
idea of non-stop continuous 3D printer ‘LOOP’ came out. There
were many ways to do it but we wanted it to be the most
efficient way possible so while we were brainstorming we got
inspired by the way that injection molding machines eject the
parts so we adapted that to our technology. This way the idea
of Loop 3D printer got shaped.”


Continuous 3D
printing means that users are able to send multiple batches of
3D models to the system. Once a batch is finished,
an automated cleaning mechanism inside the 3D printer
removes the models from the build plate, and starts the next
batch, without the need for human intervention, which enables
24/7 3D printing. We’ve seen other continuous
3D printing platforms
, like the Continuous
Build 3D Demonstrator by Stratasys
, but none based off of
injection molding.

The LOOP, which is the first industrial-grade continuous 3D
printer on the market, has a large build chamber of 250 x 350 x
500 mm – more than enough to take care of industrial 3D
printing projects. It also supports many high-quality
industrial materials, such as PLA, PETG, and ABS, and high-end
plastics like Nylon, ASA, PSU, Carbon Fiber Reinforced Nylon,
and PPSU. Additionally, thanks to a hot end that can reach
temperatures up to 400°C, the LOOP system will soon be able to
support 3D printing with PEEK and ULTEM materials as well.

When asked about the LOOP’s target users, Ustaoğlu told
3DPrint.com, “Loop 3d printer is not only a continuous 3d
printing system but also a highly stable industrial 3d
printer with high end components and a big build area. This
makes Loop 3d printer suitable for many types of
users like 3d print service providers, prototyping
centers, automotive part manufacturers, architectural model
makers, education facilities, R&D companies, medical
users and more. Basically whoever needs non-stop parts
manufacturing, Loop 3d printer is there for them.”


The most important
aspect of the LOOP 3D printer is its continuous fabrication
capability, which is possible thanks to the company’s
patent-pending ejector system. A system of spikes below the
build plate easily pushes the completed part out, and then the
ejector and storage systems collect the prints, which enables a
non-stop 3D printing cycle. This lowers human operator costs,
as they are unnecessary once they’ve sent their batch of models
to the system, and gets rid of time lost between 3D print jobs.

“Our experience working as a distributor of several 3D
printer models, including HP Multi Jet Fusion systems, has
led to us creating a 3D printer able to cater to the future
needs for large batch productions. The LOOP 3D Printer
is unique and it will enable us to set a new standard for
industrial 3D printing,” Ustaoğlu explained.

The LOOP system is easy to use and offers high repeatability
and stability, making it perfect for both industrial and
professional applications. The 3D printer itself, along with
its linear guide rails, was built out of aerospace-grade
aluminum, and features CNC-machined mechanical parts for high
mechanical accuracy.

Other technical specs include:

  • 12.5 microns of X and Y axis positioning accuracy, while a
    specially designed Z axis mechanism allows for accuracy as high
    as 0.3 microns
  • High-end dual gear extruder system and durable hardened
    steel nozzle
  • WiFi and cloud-based operations
  • Embedded 10″ touchscreen panel and built-in computer enable
    3D model slicing and printing from the LOOP user interface
  • Permanently calibrated, as the specially designed and
    accurate build plate does not require manual calibration

LOOP 3D Printer at formnext

The LOOP 3D Continuous 3D Printing Platform is now available
for pre-order, and deliveries will be handled
through Teknodizayn’s growing network of global resellers.
