How the Lisa Pro 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 by 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...

C. Parameters - print design guide
Wall thickness
The 3D model’s wall must be thick enough to support the model.
We recommend with 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].
13  Sinterit Lisa PRO USER MANUAL

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 the
beginning user.
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.
