Before Using the Machine
5.1 SLA Resin (Photo Curable Resin)
Please be cautious of the followings when handling Resin.
- Wear nitril gloves all the time while handling the resin.
- Resins being used for this machine should not be used for the food, drink and medical purposes.
- Do not eat or inhale resin in any forms.
Be careful not to let the resin enter your body through eyes or nose.
- Do not expose the resin to heaters or stoves, direct sunlight, ultraviolet rays, inert gas and oxidizing agents.
- Resin is vulnerable to various lights such as sunlight, fluorescent lamp, LED bulb.
Do all the works on the resin, such as printing, post-processing, cleaning, etc., in a dark place with no
light. If the working place requires some lights, please use a UV protection film on the light to weaken
the light intensity.
- Do not use touch screen with hands or any tools contaminated with resin. Touch screen may
malfunction if it is covered with resin.
- If storing the remaining resin is necessary, resin must be cleaned remove dirt, plastic debris, etc by
filtering. Use dedicated container to store resin and seal the cap firmly.
- If resin is stored in the resin tank, it can be cured or color dye can be separated. Stir the resin with
a rubber scrapper or spatula in every 24hours to mix it up well. If resin tank is damaged due to improper
resin tank management, manufacture will not take a responsibility.
- Resin in a liquid form is not a general waste and should not be poured into drains. It must be disposed
of by a designated waste disposal company.
If difficult to dispose it by a waste disposal company, please dispose of it after pouring it in a transparent
plastic bag and curing it by exposing to sunlight or UV light.
Cured resins can be disposed with other normal garbage.
- Be careful not to get any resin on the parts other than the resin tank, platform and inside the machine.
This may cause malfunction or malfunction of the unit.
Important
- Please note that you shall follow our technical information or support being described in this manual at
your own discretion and risk.
- We are not responsible for the use and handling of resin other than those described in this manual.
- Resin specifications can be changed without any notice.

5.2 Isopropyl Alcohol, IPA
Please be cautious on the followings when handling the IPA.
- Please make sure to wear nitril gloves all the time while using the IPA
- Carefully follow the safety instructions provided with the isopropyl alcohol you purchase. You should
consult the chemical manufacturer or supplier for more in depth safety information.
- Isopropyl alcohol can be flammable, even explosive, and should be kept away from heat, fire or sparks.
- Any containers holding isopropyl alcohol should be kept closed or covered when not in use because
it is highly volatile.
- Need to replace new IPA for the best performance regularly because it can be easily diluted.
Caution
- We do not manufacture and sell Isopropyl alcohol. Consult the manufacturer for details of safety
information.
- When disposing IPA, be sure to follow the instructions specified by the manufacturer or supplier.
Important
- Do not use Isopropyl alcohol or ammonia-based cleaner to clean orange cover. Acryl(PMMA) material which
orange cover is made of can cause chemical reaction with some types of chemicals such as IPA,
ammonia-based cleaner, etc, and eventually the cover can be broken or deformed.
- When cleaning Acryl material parts, use only clean microfiber cloth and a dedicated cleaner for acryl (PMMA)
material (e.g. NOVUS No.1 Plastic Clean and Shine).
- Non-microfiber cloth or paper towel can cause the scratches on the parts.

Before Using the Machine
7. Ventilation
Caution
- Use the machine in a place with good ventilation.
Do not block vents. Inappropriate cooling may lead to high temperatures inside the machine.
- In general, a new machine may produce small amount of gaseous components, so ensure good
ventilation when the machine is used for the first time. If the machine is in operation for an
extended time, do not stay in the same room for a long time.
- Basically, it is recommended to expand the supply and exhaust facilities or install a ventilation
device such as a fan at the 3D printer installation site .
- It is recommended to use indoor ventilation as follows.
Indoor ventilation
(ventilation device)
1. Considering the indoor space area, use an indoor ventilation fan with an appropriate
capacity
2. Ventilation fans are operated before the 3D printer is operated, and at least 1 hour
after the 3D printer is completed.
3. Do not completely seal the door while the fan is running, but keep the door slightly
open.
4. Use of a ventilator is carried out with natural ventilation.
Indoor ventilation
(natural ventilation)
1. In spring and autumn, open windows (5~20cm) considering the outside air.
2. In summer and winter, windows and doors are opened for 5 minutes immediately after
the 3D printer is operated, and ventilation is required for 5 minutes or more every hour.
3. After the 3D printer is finished, open the printer door and ventilate for at least 30
minutes
►Natural ventilation is performed considering whether polluted external air is flowing
in depending on the surrounding environment and atmospheric conditions.
- 3D printer during operation are recommended for industrial dust masks to wear
