Printer Introduction

Alkaid is made in black and white with 6.08 "2K resolution, enabling X/Y accuracy up to 0.05mm. Alkaid's z axis uses a high-cost linear guide rail, which has the characteristics of high rigidity, high load, automatic self-aligning, absorbing assembly errors, etc., which can effectively improve the overall printing quality of 3D printers. A new generation of matrix light source, using 15 pieces of high-light power quartz lamp beads, with professional optical materials made of matrix lenses, so that ultraviolet irradiation on the LCD screen more uniform, higher intensity, effectively improve the printing speed and accuracy.The rugged Alkaid innovates by integrating UV lamp beads on the aluminum substrate at the bottom of the machine, allowing for greater heat dissipation area. With the cooling fan, it can effectively reduce the temperature of the lamp board and extend the service life of the UV lamp beads. Alkaid is easy to operate and affordable, making it ideal for beginners and amateurs. In addition, geeetech is able to provide ODM and OEM custom design and manufacturing.

How to clean and maintain the resin tank and FEP film

Cleaning the resin tank and FEP film

1. Preparation: Wear protective gloves and avoid direct contact with the resin. Prepare cleaning tools, including a soft scraper, a fine mesh filter, isopropyl alcohol (IPA, concentration above 95%), a soft cloth or paper towel.

2. Cleaning the resin tank: Carefully pour the uncured resin from the resin tank back into the resin bottle and filter it with a fine mesh filter to remove any cured particles or impurities that may exist.

3. Remove the FEP film (if necessary): Depending on the design of the resin tank, use appropriate tools (such as a screwdriver) to remove the screws or clamps that secure the FEP film.

4. Cleaning the resin tank: Pour an appropriate amount of isopropyl alcohol (IPA) into the resin tank and shake it gently to dissolve the remaining resin. Use a soft cloth or paper towel to gently wipe the tank walls and bottom to ensure that all the resin is removed. Avoid using rough or hard tools to avoid scratching the resin tank.

5. Cleaning the FEP film: Soak the FEP film in isopropyl alcohol for a few minutes and shake it gently to dissolve the remaining resin. Use a soft cloth or paper towel to gently wipe the surface of the film to ensure thorough cleaning.

6. Drying: Use a clean cloth or paper towel to wipe the isopropyl alcohol on the surface of the resin tank and FEP film. Make sure it is completely dry before the next print.


Maintaining the resin tank and FEP film

1. Regular inspection: Check the status of the resin tank and FEP film regularly to ensure that there are no scratches, perforations or deformations. If any damage is found, replace it in time.

2. Avoid direct sunlight: Resin is sensitive to ultraviolet rays, so avoid exposing the resin tank to direct sunlight to prevent unused resin from curing prematurely.

3. Storage Note: If the printer is not used for a long time, it is recommended to pour out the resin in the resin tank and clean it, and store the resin tank and FEP film in a dry and cool place.

4. Handle with care: When cleaning and handling the resin tank, be as gentle as possible and avoid using sharp tools or excessive force to reduce damage to the film.


Through regular cleaning and maintenance, the service life of the resin tank and FEP film can be maximized to ensure the continuous and stable operation of the 3D printer.

Trouble Shooting

The pressure plate is damaged

The pressure plate is broken as shown in the figure below. The pressure plate purchase link The pressure plate

A2.png

The rupture of the pressure plate will cause the resin in the resin box to leak onto the printing screen, and the resin is corrosive and likely to corrode the printing screen. When replacing the FEP film, please be careful not to use too much force, just make sure that the screw is screwed properly, if too much force will cause the pressure plate to crack.

Print screen damage

Please refer to the replacement print screen above. If the resin in the resin box leaks onto the printing screen, the resin is corrosive and is likely to corrode the printing screen.

Resin non-stick forming platform

1.Please re-level, be careful not to tighten all screws at once after zero, which will cause the forming platform to skew. Turn the four screws in turn until they are half loose and half tight, and then tighten all screws after ensuring that they are level. Try printing another model after leveling it.

A8.png

If the hot bed is still non-stick, please perform an exposure test to check that the print screen and UV etc. can work properly.

2.If the support is not added enough, it is easy to lead to the failure of model printing, if this is the reason, it is necessary to re-slice the model and add enough support;

3.Exposure time is too short also easily lead to printing failure, then the exposure time can be extended appropriately (in s);

The display does not light up

Check whether the power indicator is on when the power is powered on. If the indicator is on normally, disassemble the base according to the following figure.

A9.png

Check whether the cable connecting the power supply to the mainboard is loose.

A10.png

If it is not loose, please connect the motherboard and the computer with a USB cable, and check whether the device manager on the computer can recognize the motherboard. If not, the motherboard is broken and needs to be replaced. If it can be identified, it is the display is broken, need to replace the display, please contact technical support to buy.

Cleaning of resin after printing

Please click the button on the screen to clean the tray and clean it with alcohol or professional IPA cleaner. If the cleaning is still incomplete, please click the link below to buy a cleaner. GWC01GWC02

A6.png

The printer cannot recognize the file

Alkaid can only identify files with the suffix.ctb and print them. Please print the cut files on the USB flash drive.

A11.png

If the printer cannot print.ctb files, refresh the firmware. Below is the firmware link, please download the firmware file in the red box and refresh it.

A12.png

If the file is still not recognized after updating the firmware, then the USB port is damaged and needs to be replaced, please contact technical support to replace it.

Support adding technique when slicing

1.Thin supports are easier to remove and cause less damage to the model, but a higher support density is required to ensure the strength of the support.

2.Check again after automatically adding support. Some places where the support density is not enough, you need to manually add some, or some of the bottom of the suspension without support, you can also increase appropriately.

3.When the model is printed without a bottom, pay attention to the amount of support closest to the bottom must be sufficient.

4.For models that need to be pumped and punched, support is added after the shell is pumped and punched.

5.Some models are uneven at the bottom, and can be appropriately raised to print, or offset a little downward (if the bottom is not high), which is equivalent to cutting a small part of the bottom.

6.Hollow models or after the shell, remember to drill holes so that the resin inside can drain out.

The model is split-level

1.Check model support

Check that the model support is adequate. When the model support is not in place and the density is not enough, it is easy to cause the model to shake slightly when printing and demoulding. In this case, it is recommended to increase the support density or manually add the support fixed model.

2.Check FEP film

Check whether the release film of the material box is relaxed. If there is slack, it is recommended to tighten the release film steel ring.

A13.png

3.Check Z-axis operation status

If there is abnormal noise in the Z-axis operation, the swing amplitude is too large, or when the Z-axis is running up and down, the manual printing platform is stuck, you need to loosen (do not screw off) the 8 screws that fix the printing platform on the wire rail, and then move the Z-axis up and down, and lock it again after smooth

4.Check print platform

Check that the printing platform is locked. When locking, pay attention to the diagonal lock, and pre-lock first, and then lock all.

5.Check tank

Check the tank for residue. Residue can cause the model to print faults, so check the tank before each print and clean the internal residue in time.

There is residual resin in the model

1.The support is too little to pull the model. Need to re-slice to modify the support.

2.If there is a problem with the model itself, the problem can be solved by modifying the modeling;

3.Wall thickness is also a very important parameter, less than 0.5mm mechanical strength will be relatively poor, want to ensure the effect of the wall thickness can be increased to more than 1 mm;

4.If the material tank or release film is damaged, it will lead to poor light transmission, and the liquid resin can not cure well, in this case, a new release film needs to be replaced.

Precautions for resin

1. The resin is disposable and cannot be reused.

2. Do not touch eyes, skin or clothing, taste or ingest the resin material. Use only under good ventilation.Please pay attention to air circulation and take protective measures. Wash thoroughly after operation.

3. Resin is liquid state, there is a slight smell, please wear a mask when using, so as to avoid inhalation of aerosol, causing infection.

4. The resin should be stored in a sealed container, sealed in time after use, and placed in a dry and well-ventilated place, not exposed to sunlight.

5. In case of accidental inhalation, leave the scene and seek medical attention.

6. In case of contact with skin, wash skin with soap and water or seek medical advice.

7. In case of contact with eyes, immediately open eyelids, rinse with soapy water for about 20 minutes and seek medical attention.

8. If accidentally inhaled or swallowed, do not induce vomiting, keep the state of rest, and promptly sent to the hospital for treatment.

9. Disposal of waste in accordance with local environmental regulations.
