A: You need to adjust the position of the model support in the slicing software; otherwise, the part of the support will fall while printing. The printing speed is not suggested to set too fast. In addition, the resin, section parameters, model placement, and support that you use will also affect the printing effects.
A: Hello, please consider the following aspects.
Check if there are impurities on the resin or resin vat blocking the forming area, causing holes in the printed model.
Check if the supports are added properly, as inadequate supports may fail to hold the model effectively. You need to add medium supports in overhanging areas and where the model has significant suspended parts to prevent detachment.
The motor speed should not be too fast. You can try reducing the motor speed for printing.
Additionally, the FEP film can wear out after prolonged use, leading to reduced light transmission and poor resin curing. You may need to replace the FEP film with a new one.
A: Hello, printing quality issues can arise due to operational differences. You can adjust your printing method from the following aspects:
1. Increase exposure time. Insufficient exposure may lead to inadequate layer curing. During the continuous layer-by-layer construction process, if a layer is partially missing due to insufficient curing, subsequent layers cannot properly continue on the previous layer, resulting in layer separation issues.
2. Add sufficient supports. When model supports are inadequate or not dense enough, it can cause slight shaking during print removal. It's recommended to increase support density or manually add medium supports to secure the model.
3. Replace the FEP film. A loose FEP film in the resin vat can affect model printing.
4. Hollow models need drainage holes. Printing models without holes can create a vacuum effect, increasing the force required to separate the model from the FEP film during lifting, leading to layer lines.
5. Check for any stuttering of the build platform. Inspect if there are any abnormal noises or excessive swinging during Z-axis movement.
6. Lifting speed during printing. If the lifting speed is too fast, the next layer starts before the previous one is fully cured, easily causing delamination between layers, which is directly reflected as layer separation issues.
A: Before printing, it's recommended to check if the printer's coupling screws, build platform, lead screw, etc. are loose, and confirm the motor speed (should not be too fast).
A: You need to ensure proper storage of the resin, as this affects model adhesion. If the local temperature is too low, causing poor resin reactivity, you can soak the resin bottle in hot water for about ten minutes before use. Moreover, special resins contain many additives, and if the photosensitizer in the resin itself has too strong or too weak "light absorption" ability, it can affect the model curing effect.
You can try printing the test model first to check the printing effect. Re-slice and re-level. The model may have insufficient supports in the slicing, requiring us to add more. On the other hand, if the model itself is large but has a small contact area with the platform, it may cause the model to fall off when printing the latter half as the overall weight increases and the surface attached to the platform is not sufficient to hold the entire model.
Add a base with a larger contact area, and try printing again after these modifications. Before reprinting, filter the resin through a filter net to avoid model debris affecting the second print or even damaging the LCD screen.
A: You can assess from the following aspects. Check if the UV lamp lights up normally during the exposure test. If the UV lamp doesn't light up, you can refer to the next FAQ:The UV lamp of the resin 3D printer doesn't light up, what should I do?
If the UV lamp is normal, check if the metal patches on the LCD screen cable are damaged; the metal patches on the LCD screen cable need to align with the pin direction on the port. Also, when connecting the LCD screen cable, it needs to be flush with the port. If you don't connect it flush, it can also cause abnormal LCD screen exposure. If all the above checks are normal, then it can be determined as an LCD screen issue, and it's recommended to replace the LCD screen.
A: You need to unplug and replug the UV lamp cable; if the UV lamp still doesn't light up, you need to measure if there's a 24V voltage output at the output port of the power adapter.
No voltage indicates a faulty power adapter that needs replacement; if there's voltage, please continue to check the adapter board.
Before checking the adapter board, you need to clear the screen first. Then, measure if there's a 24V voltage at the lamp board interface on the adapter board. No voltage indicates a faulty adapter board that needs replacement. If there's about 24V voltage output at the lamp board interface on the adapter board, it indicates a faulty LED board. You only need to replace the UV lamp and cable.
A: Hello, display screen abnormalities are slightly complex (check situations: display screen cable/power adapter output voltage/adapter board cable).
You need to refer to the following steps:
Check the display screen cable. If it's damaged, you only need to replace it with a new display screen cable; If the display screen cable is normal, unplug and replug it. Note that the metal patches should face the outer side when connecting, and it should be inserted all the way in, flush with the cable port; It could also be unstable output voltage from the power adapter.
You need to measure if the power adapter has a normal 24V voltage output. No voltage indicates a faulty power adapter that needs replacement. If there's voltage, please continue to check the adapter board.
Check if the adapter board cable is damaged. If damaged, just replace it with a new adapter board cable; If the adapter board cable is normal, unplug and replug it. Note: The metal patches on both ends of the cable should face the inner side when connecting, and it should be inserted all the way in, flush with the cable port;
A: You need to download the latest software version from the Creality Cloud official website and update the current version on the host to the latest version;
Check if the device is properly connected to WiFi. If no WiFi signal is found, it's recommended to change the router's WiFi network band to 2.4GHz frequency or test by connecting to a mobile hotspot.
Confirm that the computer and device are on the same local network. You can use the CMD command on the computer to ping the device IP to confirm. If the ping is the same, it means they are on the same network; if the ping is different, it's recommended to use a mobile hotspot and let both the device and host connect to it and try again. On the control panel of the mainboard, find the device firewall and set the domain network to "off".
A: First, use your phone to open a 2.4GHz frequency band network hotspot to connect.
If this doesn't solve the abnormal network signal, you can open the bottom case and try to reconnect to WiFi; if the connection fails, check if the WiFi antenna in the bottom case is poorly soldered. If it's confirmed to be a WiFi antenna failure, you only need to replace the WiFi antenna.
A: You need to confirm if the device's network signal is normal when powered on.
You can test by connecting to a 2.4GHz frequency band network hotspot on your phone; update the Creality Cloud APP to the latest version;
Check if the region selection is correct. In the language and region settings on the machine, the region should be selected as: International. (Tip: The English letter "A" in the Creality Cloud icon in the upper right corner of the screen represents International). After removing the offline device, you need to rebind to Creality Cloud according to the operation guide.
A: First, confirm that the device's network signal is normal when powered on.
You can test by connecting to a 2.4GHz frequency band network hotspot on your phone; connect the camera to a computer and use the computer to check if the camera can capture images normally. If it can't output images, it's a camera issue and needs to be replaced; check if the machine's current firmware version is the latest version.
