3D printers
Desktop 3D printers have become more
affordable and easier to operate. Additive
manufacturing has been signifi cantly adapted
in certain fi elds, including dentistry and
medicine; orthodontics has integrated it
before many other sectors of dentistry.
3D-printing dental models to thermoform
the aligners is a critical step in the
aligner manufacturing cycle. This step can
become a bottleneck and add stress to the
daily operation in a practice.
A common question about 3D printers
is, " I fi nally decided to start 3D printing.
Which printer do you recommend? " Before
we dive deep into information on desktop
3D printers, let's look at the four core
attributes of an in-offi ce 3D printer. An
optimal one should work well with these
four main concerns:
* Reproducibility: It should print
accurate parts at 95% success rate
when calibrated.
* Print time: It needs to match the
weekly demand of a practice.
* Adaption learning curve: It should
require only reasonable levels of
maintenance and training to operate.
* Economics: Its cost of operation
must be reasonable, too.
Someone's printer of choice will change
based on the priority ranking of these
attributes. For example, a practice that
will create 100 models per week might opt
for a different printer than a practice that
needs only 10 models per week on average.
It is important to mention that the
initial cost of 3D printing adaption is often
a primary driver in choosing a printer. With
multiple options on the market, it doesn't
make sense to spend more than $10,000
on a 3D printer at this point. ■
Next month:
A deeper dive into the types
of 3D printers and materials
In Part 2 of this series, Dr. Rooz Khosravi discusses the different types of 3D printers
and thermoforming plastics available on the market, explains common postprinting
processes required of the machines, and recaps the logistics behind personal branding
of products printed in-offi ce.
