Check after unpacking
Open the package to confirm that the components are complete, then check the
printer's functions to ensure that it works properly.
❶Test power function：Connect the power supply. After the printer is powered on, conrm that
the indicator of the knob is working properly and display the green breathing light.
❷Test knob function and Z-axis motion：Rotate the knob to conrm whether it can control the
printing platform move up and down, and whether the knob rotates smoothly.
❸Test photoelectric switch：Remove the printing platform and continue to rotate the knob
clockwise to control the lifting cantilever to descend until the trigger piece on the lifting cantilever
is inserted into the photoelectric switch groove to trigger it to conrm whether the lifting cantilever
stops.
❹Test print function：Remove the printing platform, download the"print.wow"print file from
SparkMaker oicial website (www.sparkmaker3d.com) and save it to the SD card. Insert the SD
card with the"print.wow" print le into the printer card slot and press the knob to start printing. At
this time, the indicator light changes from green to red and ashes, the lifting cantilever will drop to
the position of the trigger photoelectric switch, then the light board will emit light, emit ultraviolet
light, the fan will start to work, the screen will display the bottom layer patter, and wait for a bottom
exposure time. After that, the light board is extinguished, the lifting cantilever will rise a certain
distance, and then decline again, then the light board emit ultraviolet light, and the screen displays
the underlying pattern... Continue this process until the end of printing.
❺Test tank：Check if the FEP membrane at the bottom of the tank has obvious scratches or broken
holes. Pour some water into the tank to check if it will leak.

Product working principle
SparkMaker SLA 3D printer
Designing a 3D solid model through 3D software, slice the model with SparkStudio,
the generated data will be used to accurately control the switch of the light board and the
movement of the lifting platform through the main board. The light beam emitted by the light
board passes through the controllable liquid crystal screen and is irradiated onto the surface
of the liquid photosensitive resin according to the designed path. Curing a layer of resin in a
specic area of the surface. When this layer is processed, a section of the model is generated.
The lifting platform is raised by a certain distance, the solid layer is covered with another
layer of liquid resin, and then the second layer is scanned, and the second solidied layer is
rmly bonded to the previous solidied layer, so that the layers are superposed to form a three-
dimensional model. After the model is taken out of the resin, during the nal curing, and then
polished, painted or colored to get the desired product.

Precautions for resin use:
❶Theoretically, resins with a curing band of 400-410 nm can be used in SparkMaker, but if other
third-party resins are used, the printed parameters must be adjusted by themselves.
❷SparkMaker's resin can also be used on other PTFE lm or FEP lm, and the curing band is on
355-420nm SLA 3D printer, but the actual printing parameters need to be adjusted by users.
❸Damage to parts caused by the use of third-party resins will invalidate the warranty.
❹The color paste addition ratio should be less than 1%, and the resin exposure time should be
increased after adding the color paste.
❺ The resin after adding the color paste should be evenly mixed to prevent the color paste from
precipitating.
❻Do not mix a variety of dierent types of resins, and the resin properties and printing parameters
will change greatly, making it diicult to print.
❼The photosensitive resin reacts with some plastics such as ABS,PC, etc. Do not drop the resin on
such plastics.
❽ Use of third-party color paste or other stains may result in printing failure or damage to the printer.
❾Should choose the right resin according to dierent needs.
❿For models with small features and high precision requirements, deep color and high hardness
photosensitive resins should be used.
⓫Photosensitive resin with low hardness, high toughness and softness, which may have different
degrees of deformation during printing.

Resin
Resin

Color paste
Color principle：
CMYK is a color mode in which the four-color printing mode is used for color printing.
Color mixing principle plus black ink, a total of four colors mixed and superimposed to form
"full color printing".
The four standard colors are：
C=Cyan M=Magenta Y=Yellow K=key
Here K refers to the key, which is used for printing device calibration. K: It can also represent
Black, because printing is more often used in black. In addition, we also added a white color
paste. C+M=Purple
M+Y=Orange
C+Y=Green
Method of operation：Pour the resin into the paper cup rst, then add a drop of color paste
to the cup, stir evenly, then add the resin and mix evenly.
Notice：
Adding a white color paste will make the color soft.
Adding black paste will make the color dignied.
Users can adjust dierent doses and ratios to call up richer colors.
The color paste addition ratio should be less than 1%, and the resin exposure time should be
appropriately increased after adding the color paste.
The resin after adding the color paste should be stirred evenly to prevent the color paste from
being precipitated.

turns into red and ashing, and the printer enters the printing state.
3. Stop: In printing mode, long press the knob, the indicator will turn blue and eventually turn green,
which is to terminate printing.
4. Pause: In print mode, press the knob and the indicator will turn blue. The printer will stop after the
print platform is lifted 30mm after the current print layer is cured.
5. Continue: After the printing platform is lifted by 30mm and stopped, press the knob, the printing
platform will descend and continue printing, and the indicator light will turn red and ashing.
6. If there is no print le in the SD card or the SD card is not recognized, after pressing the knob, it
will change from green to red and quickly turn to green again.
