2. Safety Instructions
Always observe the following safety precautions:
- Keep the printer away from flammable materials and heat sources.
- Ensure proper ventilation during operation.
- Do not touch the hot nozzle or heated bed during operation or immediately after printing.
- Always disconnect power before performing maintenance or cleaning.
- Keep out of reach of children and pets.
- Verify the power supply voltage switch is set correctly for your region (115V or 230V) before plugging in the device. This switch is typically located near the power input.
3. Setup and Assembly
3.1 Unpacking and Inspection
Carefully remove all components from the packaging. Inspect for any visible damage during transit. Refer to the packing list to ensure all parts are present.

3.2 Assembly Steps
The SUNLU T3 3D Printer is designed for easy assembly, typically completed in three main steps:
- Attach the gantry to the base.
- Mount the power supply unit/control box.
- Install the filament spool holder.
Ensure all connections are secure and cables are properly routed.

3.3 Initial Leveling
The T3 printer features 16-point automatic leveling. This function assists in achieving an even print surface. It is recommended to perform auto-leveling before your first print and periodically thereafter.

4. Operating Instructions
4.1 Filament Loading
Insert the filament into the extruder mechanism. The T3 features a double gear metal extruder for stable filament output. Ensure the filament feeds smoothly without kinks.

4.2 Printing Process
Load your 3D model file onto the printer via the provided TF card. Select the desired file from the printer's interface. The T3 supports high-speed printing up to 250mm/s, significantly reducing print times.

4.3 Smart Features
- Filament Clog Detection: The printer will suspend operation and return to the origin if a clog is detected. Users can then clear the clog and resume printing.
- Filament Break Detection: The T3 detects abnormal filament feeding, such as run-out or breakage, and pauses printing to prevent print failure.
- Power Off Resume Printing: In case of a power outage, the printer's memory function allows it to resume printing from where it left off once power is restored.
- Magnetic Build Plate: The flexible magnetic build surface allows for easy removal of finished 3D models without deformation. It also features ultra-fast heating.

5. Maintenance
5.1 Belt Tension Adjustment
Over time, belts may loosen, affecting print accuracy and potentially causing noise. The T3 features X-axis and Y-axis belt adjusters to maintain proper tension and printing accuracy.

5.2 General Cleaning
Regularly clean the print bed, nozzle, and other accessible parts to prevent debris buildup. Use appropriate tools and cleaning solutions as recommended by the manufacturer.
5.3 Hot End Maintenance
Periodically inspect the hot end assembly. Ensure all components are securely fastened and free from filament residue. If necessary, carefully disassemble and reassemble the hot end, ensuring proper seating of all parts.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power upon startup | Incorrect voltage switch setting, loose power connections, internal wiring issue. | Verify the power supply voltage switch (115V/230V) is correctly set. Check all power cable connections. If issues persist, contact support. |
| Filament not extruding / Clogging | Nozzle clog, tangled filament, incorrect temperature. | Utilize the printer's clog detection feature to pause and clear the nozzle. Ensure filament is untangled and loaded correctly. Verify print temperature settings. |
| Prints not adhering to bed | Uneven bed, dirty print surface, incorrect bed temperature, first layer height issues. | Perform auto-leveling. Clean the magnetic build plate. Adjust bed temperature according to filament type. Calibrate first layer height. |
| Visible ringing or ghosting on prints | Loose belts, excessive print speed/acceleration, unstable printer placement. | Adjust belt tension using the X-axis and Y-axis adjusters. Reduce print speed and acceleration settings in your slicer. Ensure the printer is on a stable surface. |
| Filament run-out or breakage during print | Empty spool, brittle filament, excessive tension. | The printer will pause automatically. Replace the filament and resume printing. Store filament properly to prevent brittleness. |
