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’s 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 2018 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, device, product) –
a selective laser sintering (SLS) device 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 powder is suitable for printing detailed objects, rigid and extremely durable
against unfavourable conditions (such as temperature). Due to its mechanical
strength and heat resistance, dedicated for functional prototypes or end-use parts.
4. FLEXA BLACK, FLEXA GREY (Flexa) – a powder from the Thermoplastic
Polyurethane Elastomers (TPU) group. Elastic, similar in its properties to rubber.
Possesses good formability properties (returns to its initial shape). Suppresses hits
and shocks well.
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. FEED BED (Source, Source 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 are using Flexa Black or Grey. If using
PA12 - suitable for printing after refreshing by 30 % of Fresh Powder.

C. Contents of the Sinterit Lisa pack
● The Sinterit Lisa 3D Printer;
● A package for the additional equipment;
13  Sinterit Lisa USER MANUAL

D. Parameters - print design guide
Wall thickness
The 3D model’s wall must be thick enough to support the model.
We recommend working with 0.8 [mm] for larger objects, in smaller
objects you can have a lower wall thickness of 0.4 [mm].
Embossed and engraved details - minimum detail size
Selective Laser Sintering is one of the 3D Printing processes with
the highest accuracy; up to 0.1 [mm] is enough to create clearly
visible details. If you plan to put some embossed and engraved
DETAILS, we recommend adding the minimum thickness of 0.15
[mm] and depth of 0.15 [mm].
Embossed and engraved text
If you plan to put some TEXT embossed we recommend adding a
minimum line thickness of 0.5-0.6 [mm] and a depth of 0.5 [mm].
Use a bold sans-serif font for readability, such as Arial Bold f.ex.
Minimum feature size
The minimum feature size for printing with SLS is 1 [mm]. If your
feature is a thin wire connected on both sides, you can go slightly
thinner to 0.5 [mm], otherwise, we recommend at least 0.8 [mm]
thickness.
Functional gap - moving or interlocking parts
A powerful feature of SLS is that you can print moving parts in one
go. You should keep at least 0.2 [mm] clearance between
elements. We recommend keeping at least 0.5 [mm] if you are a
beginning user.
14  Sinterit Lisa USER MANUAL

Escape holes
Sometimes you have to increase your clearance or create extra
escape holes for the powder to get out f.ex when you have moving
parts like hinges over a long distance. We recommend making in
the model at least 4 [mm] diameter for one escape hole, 2 [mm] for
two or more.

trained personnel.
A. Environment and place of installation
● The Sinterit Lisa Printer should be placed at room temperature.
● The room must be well ventilated, adequately to its size.
● The product should be placed on a flat, stable surface that extends beyond all edges
of the product. If you place the product by the wall, the distance between the product
and the wall should be greater than 500 [mm] (20 [in]).
● The product will not work properly if it is set at an angle.
ATTENTION! Do not place or store the product:
● outdoors;
● in areas with large amounts of dust;
● in places subject to shocks, vibrations, high temperature and/or
humidity, and extreme changes in temperature and humidity;
● near water, or heat sources;
● near inflammable and volatile substances, concentrated acids or
corrosive vapours;
● in places easily accessible to children and animals.
15  Sinterit Lisa USER MANUAL

ATTENTION!
● Never use wood, equipment with wooden elements and flammable
substances while working with the printer.
● The minimum distance between the printer and wooden parts is 200
[mm].
● The printer emits large amounts of heat (60oC), and therefore it is
prohibited to place it on wood or wooden furniture.
B. Power supply:
● Use only the power cord supplied with the product.
● The printer must be connected to a grounded outlet to prevent electric shock in the
event of a fault.
● When connecting/disconnecting the plug to/from the power source always hold the
cover, not the cord.
WARNING!
Do not use cables from other devices. Using the power cables from other
devices or connecting the power cord supplied with the product to other
