    ©How to get a print model?

    ❶ Download the print file "print.wow"(for SparkMaker version)or "print.fhd" (for SparkMaker FHD version) le that can be printed directly from the of cial SparkMaker website (www.sparkmaker3d.com).
    ❷ Download the STL le from the 3D Print Model website or convert the model le to the STL le format.
    ❸ Design the model using computer 3D design software and then export the model to a le in STL format.

    ©How to update the firmware?

    ❶ Download the latest update rmware from the of cial SparkMaker website (www.sparkmaker3d.com).

    ❷ Unzip the downloaded update rmware update.wow (for SparkMaker version) or update-FHD.wow (for SparkMaker FHD version) and save it on the SD card.
    ❸ Turn off the power to SparkMaker.
    ❹ Insert the SD card into the SparkMaker card slot.

    ❺ Power on the SparkMaker.
    ❻ The indicator on the knob will turn purple(if it is SparkMaker FHD version,you need click the knob when knob will turn purple),and then the light started ashing, nally turn green,which means the update is successful.

    ❼ Use your computer to delete the update rmware from the SD card.
    ❽ Finish updating the rmware and start printing.

    ©How can I check if there is a problem with the print file?

    Open the *.wow(for SparkMaker version)or *fhd(for SparkMaker FHD version) slice le with SparkStudio computer software and check if the pattern of each layer of the slice is normal.

    ©Why does the indicator change from green to red and then quickly change back to green when the SD card is inserted and the knob is clicked?

    ❶ The SD card is not recognized or has been damaged. A new SD card needs to be replaced. The SD card should be a C10 high-speed card with a capacity lower than 32GB. The le system format is FAT32. The SD card is completely unlocked by hardware,and the metal contacts are free of stains.

    ❷ The direction or depth of the SD card insertion is incorrect. It needs to be adjusted to make the metal contacts contact.

    ❸ If you use the knob to control the printer,check if the print file named in the SD card is"print.wow"(for SparkMaker version)or "print.fhd" (for SparkMaker FHD version). If other le names are used,they will not be recognized.
    ❹ Open the print le with SparkStudio and check if there is a problem with print le.

    ©Why does the platform continue to drop without stopping after clicking the knob to print?

    ❶ The platform is not leveled,so that it cannot be lowered to the lowest point. The photoelectric switch has not been triggered,and the platform should be leveled rst.
    ❷ There is residue on the platform or in the tank,so that it cannot be lowered to the lowest point. The photoelectric switch has not been triggered. The residue on the platform and in the tank should be cleaned.

    ❸ The trigger piece on the platform is not aligned with the lower photoelectric switch. The trigger piece should be inserted into the middle notch of the photoelectric switch.
    ❹ The photoelectric switch is damaged or the photoelectric switch is not installed correctly.

    ©Why is the screw movement not smooth?

    ❶ The Z axis is not corrected. The direction of the lead screw and the guide rail are not parallel,which creates motion resistance and needs to be corrected again.
    ❷ The screw needs to add some grease.
    ❸ The screw is blocked by the cured resin and needs to be cleaned.

    ❹ The copper nut mounting screw is too tight,the screw is stuck,and the copper nut mounting screw should be adjusted to make the screw move smoothly.

    ©Why does the model need to add support?

    The gravity and release force need to be overcome during the printing process. Therefore,the minimum point and the suspended part of each layer must be supported. In order to ensure that the model is not deformed and not broken,the model needs to add more support to strengthen the support structure to overcome the release force.

    ©What is the printing time of SparkMaker SLA 3D printer?

    SparkMaker SLA 3D printer is a face-to-layer printing method. The printing time is only related to the height,the number of printed layers,regardless of the cross-sectional area. In the case of the same layer thickness,the shorter the model,the less time is spent printing; at the same height,the larger the layer thickness is,the less time is spent printing. It should be noted that the larger the layer thickness,the longer the single layer exposure time and the worse the printing quality.

    ©How much resin is suitable for pouring into the tank?

    Less than 240ml resin should be poured into the tank. Do not pour in too much resin,it will result in resin over ow damage to the LCD screen.

    ©Why is the resin placed in the tank solidified?

    ❶ The tank is placed on a balcony or other place with a strong light source to cause the resin to cure.

    ❷ The UV light emitted from the side of the machine is re ected and applied to the surface of the tank to solidify it.

    ©When the liquid photosensitive resin in the tank is printed,there are a lot of bubbles,which will affect the printing? How to remove?

    ❶ The liquid resin can place for a period of time to eliminate air bubbles.

    ❷ Keep the liquid resin without bubbles and print out the model without bubbles.

    ©Why are there bubbles inside the printed model?

    ❶ When printing,bubbles are present in the liquid resin in the tank.

    ❷ When printing,the falling speed is too fast,and bubbles are generated.The falling speed should be adjusted appropriately.

    ©What effect does temperature have on printing?

    ❶ The printing process should be controlled within the indoor temperature range of 24-35.
    ❷ Printing in lower temperature requires an increase in exposure time.
    ❸ The normal printing temperature is 25 degrees. For every 10 degrees reduction,the curing speed is reduced by 30%. The curing speed is increased by 30% for every 10 degrees,but it will eventually reach a stable value. Excessive temperature will cause the FEP lm to deform and damaged the liquid crystal.

    ©Why is there nothing stuck on the aluminum plate of the printing platform after the printing is finished,and the residual resin is stuck on the FEP film at the bottom of the tank?

    ❶ The printing platform is not leveled and needs to be leveled correctly.

    ❷ The bottom layer exposure time set is too short and you need to increase exposure time. If a third-party resin is used,the user needs to adjust the printing parameters by himself. It is recommended to adjust the bottom layer exposure parameters to 200 seconds.
    ❸ The set lifting speed is too fast and the model is broken,so it is necessary to reduce the lifting speed.

    ❹ The contact surface between the model and the printing platform aluminum plate is too small to cover the entire model. You need to check the position of the model or set the sinking print model.
    ❺ Check the FEP lm on the top and bottom of the tank,and whether there is any obstruction or resin residue on the LCD screen.

    ©Can I continue printing if printing is suddenly interrupted?

    No,SparkMaker 3D printer does not have this feature yet.

    ©What should I do when the print is interrupted accidentally?

    ❶ Turn off the power and remove the print platform and tank.
    ❷ Use a shovel to clean the residual solids on the platform and the tank and start printing again.

    ©Why is the bottom of the model stuck to the printing platform and the residual resin is stuck on the FEP film,after the printing is finished?

    ❶ The support of your model is too thin to pull the model.
    ❷ The support of your model is too little to hold the model.
    ❸ The layer exposure time is insuf cient,some of the support is broken and it is dif cult to pull the model.

    ❹ The model you print is too large,the lifting distance is not enough,the model is dif cult to release,and the
    lifting distance should be increased.
    ❺ Check the FEP lm up and down,whether there is any obstruction or resin residue on the LCD screen.

    ❻ Check if the UV LED on the light board is fully illuminated when printed,and if the brightness is different.
    ❼ The lifting distance is too large,and the position is misplaced when moving up and down for a long distance.
    ❽ Open the print le with SparkStudio and check for any problems with the sliced graphics.

    ©Why is a cuboid block that is the size of the screen printed on the printing platform after printing is finished, or not printed anything?

    ❶ If the LCD screen is damaged or the contact is poor,it will be completely transparent. Check the LCD screen cable and try to connect again. If it cannot be solved,replace the new LCD screen.
    ❷ Check that the lamp bead on the lamp board is lit normally when printed.
    ❸ Open the print le with SparkStudio and check for any problems with the sliced graphics.
    ❹ The copper nut mounting screw is too tight,the screw is stuck,and the copper nut mounting screw should be adjusted to make the screw move smoothly.

    ©Why is the LCD screen not working?

    ❶ The resin drop into the LCD screen and damage the LCD screen.
    ❷ The residual resin residue on the tank or platform crushes the LCD screen during printing.
    ❸ The connection cable inside the LCD screen is loose during transportation.
    ❹ Check the FEP lm in the tank,and whether there is any obstruction or resin residue on the LCD screen.

    ©Why does the bottom of the model swell?

    In order to make the model stick to the bottom layer of the platform,the bottom exposure time is longer than the normal layer,and the long under layer exposure time will cause the resin around the bottom layer expand,you can lift the model a distance and then add the bottom support.

    ©The aluminum plate of the printing platform has been scratched by the tool after repeated use,can it be used?

    Slight scratches have little effect on the model and it can be used continuously,and the rougher the metal plane,the stronger the adhesion.

    ©How to improve the printing speed?

    ❶ Use a resin that cures faster.
    ❷ Use a larger layer thickness to save printing time.
    ❸ Increase the speed of descent and the speed of lifting as appropriate.

    ©Why is the support broken during the printing process?

    ❶ The layer exposure time is not enough,the layer exposure time should be increased appropriately.
    ❷ If the support is too thin,a thicker support should be used.
    ❸ The surrounding support is not dense enough,need to add more dense support.
    ❹ Check the FEP lm up and down,whether there is any obstruction or resin residue on the LCD screen.

    ❺ The lifting speed is too high and damaged the support,the lifting speed should be reduced appropriately.

    ❻ The Z-axis motion is not smooth. Correct the Z-axis and add some grease.
    ❼ If the hardness of the resin is too low,a resin with a higher hardness should be used.

    ©Why is the cross section of the model deformed?

    ❶ Because the exposure time is too long or insuf cient,the exposure time should be adjusted appropriately.

    ❷ The resin selected is not in the speci ed curing band.
    ❸ Some points are are not adding support and the model part is sunken and deformed.
    ❹ The platform handle is not tightened when printing.

    ❺ The tank is not installed well.
    ❻ Check the FEP lm up and down,whether there is any obstruction or resin residue on the LCD screen.
    ❼ If the hardness of the resin is too low,a resin with a higher hardness should be used.

    ©Why is the height of the printed model incorrect?

    ❶ The platform is not leveled.
    ❷ Z-axis stuck,the Z-axis should be corrected and grease added.
    ❸ The platform handle is not tightened when printing.
    ❹ The underlying exposure time is too long and the bottom layer is in ated.
    ❺ Because the exposure time is too long or insuf cient,the exposure time should be adjusted appropriately.

    ❻ The resin selected is not in the speci ed curing band.

    ©How to deal with a layer of resin residue on the LCD screen?

    The resin that is cured on the LCD screen is usually a lm,which can be peeled off by hand or gently scraped off with a knife.

    ©Why are there ladder stripes in the Z axis direction of the print model?

    SparkMaker SLA 3D printer is a surface-curing method for layer-by-layer printing. In the case of high layer thickness,there will be a ladder stripes in the Z-axis direction of the model. This is caused by the molding principle itself,and the lower layer thickness can be selected to reduce the ladder stripes.

    ©Why is there a pixel pattern in the XY direction of the print model?

    SparkMaker SLA 3D printers use LCD screens as imaging components,so pixel patterns are inevitable on the model. White or light-colored resins can be used to visually reduce pixel patterns.

    ©Why are there details or missing features on the print model?

    ❶ The model features or details are too small,and the printer resolution is dif cult to meet the printing.

    ❷ Check that these details or features lack support or support density and thickness is incorrect.
    ❸ Open the slice le in the computer software and check if the image is missing.
    ❹ Check if the UV LED on the light board is not lit when printing.

    ❺ Check for obstructions or residual glue on the LCD screen.
    ❻ Check the top and bottom of the FEP lm of the tank for obstructions or residual resin.

    ❼ If the hardness of the resin is too low,a resin with a higher hardness should be used.

    ©Why did the model stop printing before it finished printing?

    ❶ Check if the print le is saved completely.
    ❷ Check if there is an unexpected power failure during printing.

    ❸ Check if the power socket is stable.
    ❹ Check if the SD card is plugged in.

    ❺ Check if the knob rotates smoothly and whether it a steady ashing red light during printing.

    ❻ Check that the Z-axis motion is smooth.
    ❼ Check if the resin in the tank is suf cient.

    ©Note on the use of the LCD screen

    ❶ The normal life of the LCD screen is about 800 hours,and the LCD screen warranty period is 2 months.

    ❷ The resin or other liquid on the LCD screen will damage the LCD screen.
    ❸ Excessive pressure will break the LCD screen.

    ©Note on the use of FEP film

    ❶ Carefully protect the FEP lm from scratches.
    ❷ After a period of use,if there are a lot of obvious creases on the FEP lm,replace the new FEP lm in time.

    ❸ Please clean the resin residue on the upper and lower sides of the FEP lm in time to avoid printing failure.

    ❹ When installing the tank,the FEP lm should be in close contact with the LCD screen.

    ❺ The FEP lm is stretched at the bottom of the tank. This material has low adhesion,can pass ultraviolet light,and has a long service life. Its function is elastic release,and materials such as glass and ordinary plastic lm cannot be replaced.

    ©Precautions for the use of the tank

    ❶ If the resin in the tank is not used for a long time,please pour the resin into the storage container. Don't store it in the tank for more than two weeks.
    ❷ Please do not pour in excess resin to prevent the resin from overflowing and causing damage to the LCD screen.

    ❸ Please do not put the resin into the screw mounting hole and the outer wall of the tank,which will cause the LCD screen to be damaged. If it accidentally ows in,please clean it in time.
    ❹ When installing the tank,the FEP lm should be in close contact with the LCD screen.
    ❺ The slot mounting screws should be balanced and tightened to tighten the FEP lm.

    ©Print model considerations

    ❶ The model le must have no le errors such as broken faces and le corruption.

    ❷ The long-span cantilever position,the lowest point position of the layer,the position that needs to be strengthened and so on in the model le are all added with the right thickness,the right number of supports and the correct bottom valve.
    ❸ The slice parameters such as the layer thickness,exposure time,and lift speed of the print le are set correctly.

    ❹ The slice le is completely saved in the SD card,the bottom surface is completely attached to the ground,and there is no fault in the middle.

    ❺ If you use the knob to control the printer,you need to name the print file as "print.wow"(for SparkMaker version)or "print.fhd" (for SparkMaker FHD version) and save it to the SD card.

    ©How to check if the LCD screen and light board are working properly?

    First remove the tank and printing platform,then insert the SD card with the printed file,press the knob to start printing,then wait for the light board to light up,the LCD screen displays the image,observe whether the image is normal,the light on the light board Whether the beads are normally lit.

    ©Problems about the loss of LCD screen and light board.

    The SparkMaker SLA 3D printer uses a liquid crystal screen as a graphic display component and uses a UV backlight as the light for curing the resin. Because the LCD screen is exposed to UV light,it will be damaged under long-term use. It has a life of 2-3 months under frequent use. When the LCD screen has black spots and the light transmittance is poor,the exposure time is obviously longer or the graphics or the like cannot be displayed normally,the LCD screen should be replaced in time. The UV LED board will also wear out during long-term exposure. It can be kept for 2-3 months without signi cant light energy loss under frequent use. When the light intensity is obviously weakened,the exposure time is obviously longer or there are some UV LEDs don't light or weak,the light board should be replaced in time.

    ©Do I need to leveling the platform before every print?

    The SparkMaker SLA 3D printer uses a high-precision photoelectric switch with high repeatability,so after proper leveling,if you do not adjust the Z axis,do not loosen the four screws on both sides of the platform,and do not reinstall the resin tank,normally you don't need to leveling the platform again.
