If you’re looking for the most adaptable industrial SLS 3D printer – Sonda SYS SL02 is for sure one of them. We have developed it to be as useful and cost and time effective as possible.
That is why our SLS is 2 in 1 device – it is one SLS 3D printer provided with a variable working volume. So you can have one SLS 3D printer but with both smaller and larger working chamber volumes and use them depending on current projects and needs.
SondaSYS SL02 is the only SLS 3D which is equipped with the top quality optical system: Cambridge Lightening 2 from Cambridge Technology. So that gives to our devices significant market advantages.
MARKET ADVANTAGES OF SONDASYS SL02
The build volume that can be RESIZED.
It gives impressive effects in the optimization of the production costs by adjusting the size of the build chamber volume to current needs. Consumer just choosing size 1 (265 x 265 x 310 mm) or size 2 (365 x 365 x 610 mm) and the device will prepare selected build chamber volume by itself.
Picking smaller build volume reduced heating and cooling time, also the amount of powder needed to use much smaller and lower cost per part.
Having a 3D printer with a invariable chamber size, consumer need to repeat the printing process or use other devices as need a bigger size of quantity. Whereas, in SL02 users just need to change printing settings and choose other, larger printing space. So tailoring build chamber volume to current needs allow also to speed up the process by reducing heating and cooling times.
Smooth changing the size of the laser beam spot during the printing process.
Thanks to that, the process can be speeded up with a faster filling in model. That enables significant acceleration of the process and completion of work.
How quick? That depends on the model’s size, but it can save 5-10 seconds on just one layer and then multiply this by another layer.
Changing the size of the laser beam during the printing process is also preserving the precision of external surfaces. It is all digital controlled and operated. A thicker laser beam makes the models stronger, so finally the model has less dispersed structure and have greater strength inside. That significant producing functional prototypes, tools or short-run product series.
Minimizing distortion.
Used in standard 2-axis systems f-theta lens heats too much and that causes distortions. 3-axis galvo system does not need to operate the f-theta lens. In SondaSYS SL02 3-axis galvo system distortions are minimizing and problems with lens changing the geometry by itself under the influence of temperature are eliminated. So there is no need to change the scanned portion of the working plane to evenly distribute the temperature on the lens surface, like in 2-axis systems.
Precise laser path guidance.
Advanced algorithms direct the mirrors of the galvo system in a way, that allows to take full advantage of their inertia and thus eliminate typical problems appearing in standard solutions.
SondaSYS “skywritting”
In standard 2-axis systems the laser dot moves from point A to point B. At point B the laser dot must stop and after stopping it jumps in a straight line from point B to C, then the mirror accelerates and runs further to point D. In such a system, the laser slows down at point B while it constantly releases the same energy. So at points B and C the powder is sintered harder and deeper – due to laser downtime at these points the emitted energy is greater than it should be. Mirrors when stopping still have their inertia (the X mirror responsible for the A-B segment is still vibrating and the Y mirror responsible for the C-D segment is just accelerating) and this movement, although it only lasts milliseconds can then be seen on the models, as it causes folds in angles of sharp models.
In the SondaSYS SL02 System the laser moves from point A to point B at full speed, then makes an arc, at point B the laser turns on and continues to move at full speed. Turning the laser on and off is controlled and set using the SondaSYS RP software. Algorithms of the Cambridge Lighting 2 system are responsible for the smooth movement of the laser beam. The turn on/off time of the laser is set during the first calibration of the device. These settings remain unchanged and fixed – there is no need to re-calibrate them.
High-performance materials
The heated print chamber can reach up to 300°C which enables the user to print with a wide range of high-performance materials, including PA6.
Open parameters
SondaSYS SL02 works with powders from all providers and producers.

Customization
We are able to rebuild and develop 3DP devices, taking into account almost all specific, individual customer needs. Each device manufactured by us is dedicated to the customer and is slightly different from the others. We have several options that we can modify – our customers must choose the final parameters of the printer before we start building it. Such personalization is a key differentiator on the market for us, which gives us a business advantage and the customer the opportunity to buy exactly the machine they are looking for.
