The Sinterit Lisa desktop 3D printer uses laser powder sintering (hereinafter referred to as SLS) technology for 3D printing, where powder material is heated and solidified within the machine. A layer of polymer powder is placed on the print bed in the Sinterit, and parts requiring solidification are fused according to each horizontal slice until the final product is printed.

II. 3D Printing Parameters and Model Design Guidelines
 | Wall thickness | The wall thickness for 3D printing must be sufficient to support the model. For larger objects, we recommend 0.8mm. For smaller objects, a lower wall thickness of 0.4mm can be used. |
 | Embossed and engraved details | A minimum detail size of up to 0.1mm is sufficient to print clear and visible details. If you plan to add embossed and engraved styles, it is recommended to add a minimum thickness of 0.15mm and a depth of 0.15mm. |
 | Embossed and engraved text | If you plan to add text, it is recommended to add a minimum line width of 0.5-0.6mm and a depth of 0.5mm. Use a bold sans-serif font like Arial Bold for better readability. |
 | Minimum feature size | The minimum feature size for SLS printing is 1mm. If your feature is a thin line connected on two sides, it can be slightly thinner at 0.5mm, but a thickness of at least 0.8mm is recommended. |
 | Functional gap | Movable or interlocking structures are a powerful feature of SLS and can be printed in a single print. A minimum gap of 0.2mm should be maintained between elements; for first-time users, we recommend at least 0.5mm. |
 | Escape holes | Sometimes it is necessary to increase the gap or create additional escape holes for powder to remove it when moving parts like hinges over long distances. It is recommended to create an exit hole with a diameter of at least 4mm in the model. |
III. Sinterit Studio Software Installation Guide
1. Connect the USB drive included with the device to your computer's USB port.
2. Locate the Sinterit Studio folder.
3. Double-click the SinteritStudioSetup.exe icon.
4. Select the installation language.
5. Follow the instructions on the installation screen.
6. After the installation is complete, you can use the Sinterit Studio software.
※System Requirements:
．Windows 7 or higher
．Minimum 500 MB storage space
．At least 2 GB RAM

IV. First-time Machine Use and Unboxing Steps
1. Remove the 3D printer from its packaging and carefully unwrap the protective film and paper.
2. Place it on a stable and sturdy flat surface (ideally where the printer is intended to be placed).
3. Connect the 3D printer to power.
4. Flip the power button on the back (from 0 to 1).
5. Check if the red safety button is pulled out. If not, rotate it a quarter turn clockwise.
6. Insert the key into the ignition switch and turn it a quarter turn clockwise. After a short while, the Sinterit Lisa will start.
After turning on the Sinterit Lisa, the startup screen will display three functions: "START NEW PRINT," "CLEAN PRINTER," and "ADVANCED MODE" (for previous software versions).
When using the Sinterit Lisa printer for the first time, you should select Advanced Mode to set up the printer for the WiFi network.
7. Connect the 3D Printer to WiFi
To connect the printer to a WiFi network, select the ADVANCED MODE option.
1. On the printer's touchscreen, select ADVANCED MODE.
2. On the printer's touchscreen, select ADVANCED // SELECT WI-FI.
3. Find the network you want to connect to and tap its name.
4. If necessary, enter the password and press OK.
5. Next to SELECT WI-FI, you can see the connected network.
If you wish to use the old software version, press the BACK button to return to STANDARD MODE.
8. Prepare for 3D Printing
Select the "START NEW PRINT" option and open the lid. The main screen will be displayed.
1. To open the printer, select the "UNLOCK LID" option to release the magnetic lid lock. After 10 seconds of releasing the lock, the system will count down for 10 seconds, and the magnetic lock will close again.
2. Gently press and then gently lift the printer lid.
3. Turn off the power and unplug the power cord from the outlet.
4. Carefully remove the internal transport protection and the transport protection around the laser.
5. Install the laser protection glass:
a. Secure the heating module and remove the pin (or wire) at the top inside.
(Image shows the pin or wire of the heating module.)
※WARNING! Be careful of sharp edges and wear safety gloves to protect your hands from the edges of the heating module.
b. Lower the heating module in advance to place the laser protection glass.
(Image shows the opened heater module.)
c. Take out the laser protection glass from the box (remove packaging from additional equipment).
(Image shows the unpacked laser protection glass.)
d. Carefully wipe the glass surface with an alcohol swab (ensure no fibers are left on the surface), cleaning both sides.
e. The image shows the laser protection glass correctly placed on the heater module.
f. Connect the heating module to the lid using the metal pin.
g. Clean any fingerprints or smudges on the glass again.
6. Check (with gloves or through paper) that the heater socket is stable. If there is dust/powder on it, gently blow it off.
※Note! Remember not to touch the heating bulb with your fingers or greasy objects (such as a dirty cloth). Dirt and grease can cause localized overheating and burn out the heater or even cause an explosion during printing.
7. Confirm that the powder chamber and print bed are ready (during initial startup, after unpacking, the print bed should be in the same condition as when packed with the printer), check that the wires and the coater's guide are clean (it should be in the middle of the print bed).
8. Remove the coater's cover plate and wipe the rotating shaft with an alcohol swab.
9. After completing all these steps, the printer can be reconnected to power and is ready for printing.
※IMPORTANT! A yellow triangle displayed on the side of the screen indicates a malfunction. Open the lid and immediately inspect the printer. When the lid is open and all visible components are undamaged (check them carefully); refer to the code displayed within the warning triangle and contact maintenance personnel with the device's serial number.
