3D Printer & Accessories
3D Printers
for Dental is a very widespread name in this growing era of time. It is also
known as additive manufacturing which is widely used in different manufacturing
industries as well as in dentistry.

History
The origin
of 3D printing can be traced back to 1986, when the 1st patent was
issued for stereolithography Apparatus (SLA). This patent belonged to Charles
(Chuck) Hull, the one who first invented the SLA machine in 1983.
The Modern 3D Printing Technology
In this
modern world and with the cut throat competition between the industries, it is
very important not to only provide the items on time but with precision and
accuracy specially if we talk about in the dental world.
With the
CAD/CAM Technology, which has shown to be a great tool in the dentistry, CAM
(Computer-Aided technology) has mostly relied on the milling machine but in the
recent times introduction to the 3D
printing Dental Industry has changed the game in a whole new level.

Technologies Used in 3D Printing Dental Industry
The term 3D
printer includes many uses of 3D
printing technologies in dentistry, this includes:
- Digital beam
melting (EBM)
- Digital light
processing(DLP)
- Fused deposition
modelling (FDM)
- Laminated object
manufacturing (LOM)
- Binder jetting (BJ)
- Material jetting
(MJ)
- Selective laser
melting (SLM)
- Selective laser
sintering (SLS)
- Stereolithography
(SLA)
These
technologies also sorted into 7 different types of process that describe how
the layers are made and what material can be used. It should be noted that all
the process are not suitable for every material.
- Laser or Light
polymerization or Polymerization is also for polymer and plastic (SLA, DLP)
- Material extrusion
for polymer, plastic , ceramic or anything having paste-like consistency
(FDM)
- Powder bed fusion
for polymer and metal alloys (SLM, SLS)
- Lamination or
Sheet lamination for plastic, metal alloys, paper and etc. (LOM)
- Directed energy
deposition just for metals (DED)
Most Common 3D Printing Technology:
1. Selective Laser Sintering (SLS):- It Includes multiple techniques like selective laser melting (SLM)
or direct metal laser sintering (DMLS). They have same principle but branded
differently for pa-tent reason and often varies slightly. They are often used
for the processing of ceramics and nylon while SLM is mostly used for metal
alloys.
The name of this technology is self-explanatory:
a laser targets powdered material (e.g. metal) which sinters it into the
pre-programmed shape. This type of dental printer in 3D is also called as
powder bed fusion as it uses a bed of powder to support the design and no
additional support is necessary, this keeps the post-processing minimal.
This process used in a porous and fragile
product but the final products are much denser and stronger and also very
accurate (50 - 100 µm) which makes it great for processing metal frame-works
such as CoCr or titanium.
2. Stereolithography or (SLA): Stereolithography or SLA is another very popular form of 3D printing
used in dentistry. It is one of the oldest methods of additive manufacturing.
There has been a significant advancement in this technology in the recent
years, as a mask stereolithography (MSLA) and digital light processing (DLP).
This has become one of the most popular type of 3D printers in the dental
industry.
These printers use polymerization or
photopolymerization principles: Thin increments of photo-sensitive liquid
material in a vat is cured with UV light until a whole layer is formed.
The platform then moves away from the vat vertically, thus makes a room for
another layer. These layers then adhere to each other from a self-adhesive
property of the polymer.

The biggest difference between SLA and DLP is
the formation of the layers. SLA printers form the layer point by point, while
DLP printers form a whole layer at once, this reduces the printing time
significantly. These printers provide high accurate results (40 - 100 µm). This
technology is it has small build platform so the operator needs to resort to
vertical positioning for the stacking.
3. Fused Deposition Modelling – FDM: Fused deposition modeling or FDM, is a material extrusion type of
digital dentistry and 3D Printing technology. Thermoplastic material comes in
the form of string and is pushed through a nozzle that heats the material to
its melting point. This nozzle moves over the platform and below it and deposit
the softer, melted material on the platform but only in certain places which is
determined by the pre-programmed path of the nozzle. Once the layer is
complete, the platform is lowered and a new layer forms in the same manner. In
dentistry, it is polymers and plastic material. FDM is also fairly
accurate (200 - 500 µm).
4. Digital light processing (DLP): It is a similar process to stereolithography (SLA) 3D printing
process that works with photopolymers. The major difference is the light source
in DLP and SLA. DLP uses a more conventional light source, e.g. arc lamp, it
has a liquid crystal display panel or a deformable mirror device (DMD), which
is applied to the entire surface of the vat of photopolymer resin in a single
pass which makes it faster than SLA.
Also like SLA, DLP produces highly accurate
parts with high resolution, but its similarities also include the same
requirements for support structures and post-curing. However, one advantage of
DLP over SL is that only a shallow vat of resin is required to facilitate the
process, which generally results in less waste and lower running costs.
