Always with the basic defensive measures when using the printer to reduce the risk of injury such as fire and electric shock, including the following measures

•Read all instructions before using the printer.

•Do not submerge or expose printer components to water or cleaning solutions.

•To prevent electric shock,do not put the device,power adapter,or plug into water or other liquids.

Important safety notice

•Do not place or store the unit where it can be easily dropped or easily pulled into the tub or basin.

•The printer shouldn't be used outdoors,for indoor use only.

•When removing the plug from the electrical outlet,do not pull on the power adapter.

•When pulling out the plug,grasp the plug,not the power cord.

•Do not use non-vendor original accessories or accessories,they may cause re,electric shoc,injury.

•Do not operate the device if the device power adapter or plug fails or is damaged.

•Do not directly touch liquid resin and the printed model of residual liquid resin on surface. Some people may be allergic to the resin and have different degrees of allergic reactions. At this time,wash with soapy water and seek medical advice promptly.

Precautions for using the printer

•Do not eat the resin used for printing and the printed model.

•Keep the resin out of reach of children and pets.

•Try to avoid contact between the resin and the skin. Wear gloves when operating.

•Shake the resin evenly before use.

•The resin should be stored in a cool,backlit place.

•When the resin is accidentally splashed on the eyes or skin,it should be washed with soapy water in time. If you feel unwell,please consult a doctor promptly.

•The printer should be placed in a place where there is no direct sunlight.

•The UV cover should be covered when printing.

•Avoid looking directly at the UV lamp,and if need please wear goggles.

•Do not spill resin on the working panel.

•Children under the age of 18 should be operated under the supervision of an adult.

•Use printers in strict compliance with local laws and regulations.

•Do not disassemble the printer while it is powered on to avoid danger,and disassembling the printer without permission will void the warranty.

Please keep your instruction manual in a safe place

Product working principle

SparkMaker SLA 3D printer

Designing a 3D solid model through 3D software,slice the model with 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 solidified layer is firmly bonded to the previous solidified layer,so that the layers are superposed to form a threedimensional model. After the model is taken out of the resin,clean the resin on the surface of the model with alcohol,and the nal curing,and then polished,painted or colored to get the desired product.

Color principle

CMYK is the four-color printing mode used for color printing.

Based on the principle of trichromatic mixing，with black ink,a total of four colors are

mixed and superimposed to form a "full-color printing".

The four standard colors are

C=Cyan M=Magenta Y=Yellow K=key Here K refers to the Key,it can also represent Black,because printing is more often used in black. In addition,we also added a white color paste.

Notice:

Adding a white color paste will make the color soft.

Adding black paste will make the color dignied.

Users can adjust different doses and ratios to call up richer colors. The color paste addition ratio should be less than 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.

layer thickness prints more accurately and prints for a longer period of time.

The time of bottom layer cured by the UV light,because the bottom layer is the base layer that supports the entire model,the exposure time is longer. Different resin are also have different in bottom layer exposure time.

Type of resin:

Different resins are not sensitive to light,so different resins cure at different times.Generally,the gray resin bottom layer exposure time is longer.

After printing each layer,the model is separated from the tank and lifted upwards. In general,the larger the cross-sectional area of the model or the more dispersed the model layout,the larger the lifting distance required;the thicker the photosensitive resin,the larger the lifting distance required.

©Lifting speed

The rate at which the resin is lifted upwards to separate the model from the FEP membrane after the resin has cured. When the model is separated from the FEP membrane,in order to ensure that the integrity of the model is not broken,the lifting speed should be reduced,so the platform lifting speed should be less than the falling speed. Under normal circumstances,there are small features or models

using ne support,the lifting speed should be reduced; the softer resin after printing should reduce the

lifting speed; the larger the cross-sectional area of the model or the more dispersed the model layout,the lower the lifting speed.

After the resin is cured,the platform is lifted and the speed of the lm is lowered. In general,there are
