Industrial quality SLS 3D printing right from
your desktop!
How the Lisa printer works:
The Sinterit Lisa desktop 3D printer uses selective laser sintering technology to produce your
prints. Within its chambers, a powdered material is heated up and turned into a solid mass
with a concentrated laser beam. Layers of polymer powder are placed onto the printer's work
platform, where they are selectively sintered, giving perfect industrial-quality prints:
● small elements with details,
● complicated structures,
● complex solid shapes with moving parts in one go,
● simultaneous multi-objects prints,
● extremely durable models against unfavourable conditions (such as temperature),
● solid, lightweight parts,
● and much, much more..
Lisa main features:
● Precision: high accuracy of prints thanks to layer thickness from 0,075 [mm],
● Plug-and-play: no installation or calibration needed,
● 4-inch touch screen: for a friendlier user experience,
● Wi-Fi connectivity: to track the printing process,
● Easy to operate,
● Dedicated software suite - Sinterit Studio 2016 supporting formats STL, OBJ, 3DS,
FBX, DAE and 3MF,
● Economic: powder recovery system allows printing with up to 100% recycled powder,
● Startup time: 45-60 min.
Printer ideal for:
● Functional testing,
● Rapid prototyping,
● Low volume manufacturing,
● High-heat and chemical resistant applications.

1.Dictionary
The following terms and forms have been adopted and used in the manual.
1. SINTERIT LISA 3D PRINTER (3D printer, printer, machine, device, product) –
a selective laser sintering (SLS) machine used in additive manufacturing (AM)
processes. Device dedicated for professional and quick manufacturing of three
dimensional (3D) models of spatial objects.
2. SINTERIT STUDIO – dedicated software for the Sinterit Lisa Printer. Sitnerit Studio
as a desktop application allows to prepare 3D models (set them in the printable area -
called Print Bed) and track the print status of the printer during the printing process.
3. PA12 SMOOTH (PA12, polyamide powder, nylon powder, PA powder, PA12 powder,
powder) – a polyamide powder with the granulation at 20-100 micrometers. Black and
smooth material is suitable for printing detailed objects, rigid and extremely durable
against unfavourable conditions (such as temperature). Due to its mechanic strength
and heat resistance, dedicated for functional prototypes or end-use parts.
4. FLEXA BLACK – a material from the Thermoplastic Polyurethane Elastomers (TPU)
group. Elastic, flexible and resistant to inter alia chemical agents. Similar in its
properties to rubber. Possesses good formability properties (returns to its initial
shape). Suppresses hits and shocks well. Not as resistant to high temperatures as
PA12 Smooth.
5. RECOATER – a Recoater in the form of a roller, moving on a guide bar by means
of a wire. Used to transfer the powder from the Source Bed to the Print Bed during
the printing process.
6. SOURCE BED (Source, Feed Bed) – a chamber storing new, unsintered powder.
7. PRINT BED – a chamber where the sintering of powder takes place, creating the
print.
8. OVERFLOW BIN – a chamber used to collect the excess unsintered powder,
transferred from the Source Bed to the Print Bed by the Recoater.
9. FRESH POWDER (PA12 Smooth Fresh Powder - container no. 1) – virgin powder,
used for refreshing, needs to be mixed with the used powder in correct proportions.
Fresh Powder is not suitable for printing (the print may not be successful).
10. PRINT READY POWDER (PA12 Smooth Print Ready Powder - container no. 2) –
powder ready to be used by the printer.
11. USED POWDER all the unsintered powder that remains after the printing and
cleaning process. Suitable for printing if we Flexa Black. If using PA12 - suitable for
printing after refreshing by 30 % of Fresh Powder.
