PS Dentallabor Linz
Takes Customized
Dental Appliances tothe Next Level with
Ultra-Realistic J5
DentaJet 3D Printers
Founded more than 20 years ago, PS Dentallabor Linz
is a leading expert in dental appliance production inLinz, Austria. With a team of 11 dental specialists, thelab specializes in creating highly customized dentalsplints, drilling guides, dental models and prosthetics.
To respond to collaborative feedback from dentists anddental laboratories, PS Dentallabor Linz invested in new
digital equipment and technologies in 2016, including
3D printing.
Over the past several years, PS Dentallabor Linz has
become an expert in 3D printing for dental appliances
but lacked the layer accuracy and full-color printcapabilities needed to support its growing custom
dental appliance portfolio. Looking to add ultra-realisticcolor and material capabilities to its technology portfolio
for customized dental appliances, PS Dental Linz CEO
Mst Daniel Plchot, and Co-CEO Mst Oliver Bläsius
invested in two Stratasys J5 DentaJet 3D printers.
“We develop a varied array of highly personalized
dental appliances, from models that are used for
educational purposes or surgery preparation to dental
prosthetics,” says Plchot. “3D printing has played
an important role for us, but we were nonethelessconstrained by limitations of our existing solutions,which fell short when it came to the increasing
demands from customers for realistic, customized,
color models and access to a broad range of materials.
We were also keen to update our own workflow,
minimizing post-processing for dental appliances
around 3D printing and allowing us to produce different
parts on the same tray at the same time.

Case Study“The J5 DentaJet has opened up new possibilities for
us — to the point where we can produce even the mostcomplex parts, such as implantology drilling guides,
which were impossible to produce before.”

The J5 DentaJet has drasticallyaccelerated our production of 3D printed
parts. Previously, we 3D printed twoto three parts in the same materials
overnight on one build tray. Now, theoptimized rotational build tray of the J5
printer allows us to produce as many as
30 models in the same print job overnight— even if those parts require different
materials. This has been a game-changer
in terms of the quantities of customized
models we can now produce.”

Maximizing Throughput

Most dental appliances produced by the PS
Dentallabor Linz lab are created based on patientspecific anatomy. With pressures to develop dental
appliances that need little to no post-processing
and immediately have the right fit, Bläsius and his
team needed an accurate and repeatable solution.

With the J5 DentaJet’s ability to print up to
five different materials at the same time, PS
Dentallabor Linz can load mixed trays of several
different applications into one print job, thereby
boosting production capacities.

“The precision of the J5 DentaJet has been
exceptional,” says Bläsius. “Other 3D printers weinvestigated presented limitations in layer quality,
only achieving layers of 50μm. However, the J5
DentaJet ticks another very important box inenabling us to reach 19μm. This means we can 3D
print repeatable dental applications that mirror thepatient’s anatomy exactly.”

Ramping up its production from just three to 30 3D
printed models in the same timeframe has comealongside another advantage for PS Dentallabor:
the reduction in workflow processes.

CaseStudyTitle HereBeyond precision, color has been a key driver toenable further customization of 3D printed models.
The J5 DentaJet offers access to over 500,000
colors, which supports advanced crown andbridge production. For these models, coloration of
the stumps in the front of the model can be colormatched precisely through the large color paletteof the printer, enabling faster end results andthe opportunity to perfect the design early in thedevelopment process.

“The J5 DentaJet has drastically accelerated
our 3D printed part production,” says Plchot.

has been shortened and simplified with the newStratasys 3D printer,” says Plchot. “Previously,
we invested a lot of time into planning 3D printjobs and prioritizing prints based on an everchanging timeline. For certain 3D printers, we
also had to work with liquids and needed toclean trays between use, as well as switch outmaterials for different print jobs. Now the process
is completely streamlined; there is no longera requirement to switch materials, which hassignificantly reduced the time and effort that goes
into 3D printing our models.”Document

GrabCAD Print further streamlines operations.
The lab uses the software alongside its J5
DentaJet to control and manage its print jobs.
This enables a seamless digital workflow for PS
Dentallabor Linz, as the software makes readying
data for printing easy and accessible.

Future Goals: 3D Printed Prosthetics

Case Study

Looking ahead, PS Dentallabor Linz intends tostrengthen its service offering by utilizing Stratasys
PolyJet technology to produce dentures andprosthetics for its customers. Plchot, Bläsius andthe team at PS Dentallabor are particularly looking
at the technology’s ultra-realistic color capabilities
and selection of biocompatible materials tosupport this venture.

“We immediately recognized the capabilities of
the J5 DentaJet and are particularly excited to
expand the use of PolyJet 3D printing technology
into prosthetics,” says Bläsius. “We are still in theinitial stages, but we can see that the ultra-realism
in terms of color and materials required for dental
prosthetics is achievable with the J5 DentaJet.
We anticipate this leading to business growth forus, which we would expect to support by adding
further J5 DentaJet printers to our fleet.”
