1、 Carefully read the safety data manual
UV resin suppliers should provide Safety Data Sheets (SDSs) as the main document for user safety operations.
3D printers have built-in safety features designed to prevent operators from being exposed to uncured photosensitive resins and ultraviolet radiation. Do not attempt to change or disable these features.
2、 Strictly use personal protective equipment
Wear suitable chemical resistant gloves (nitrile rubber or chloroprene rubber gloves) – do not use latex gloves.
Wear UV protective glasses or goggles.
Wear dust mask when grinding or finishing parts.
3、 General management procedures to be followed during installation
Avoid placing the 3D printer on the carpet or using a fence to avoid damaging the carpet.
Do not expose UV resin to high temperatures (110 ° C/230 ° C or above), flames, sparks, or any source of ignition.
3D printers and uncured open bottle resins should be stored in a well ventilated area.
If the UV resin is packed in a sealed ink cartridge, carefully inspect the ink cartridge before loading it into the printer. Do not use leaking or damaged ink cartridges. Please handle leaked or damaged ink cartridges in accordance with local regulations and contact the supplier.
If UV resin is stored in a filling bottle, be careful when pouring liquid from the filling bottle into the printer’s liquid tank to avoid liquid overflow and dripping.
The contaminated tools should be cleaned first, then cleaned with window cleaner or industrial alcohol or isopropanol, and finally thoroughly cleaned with soap and water.
After printing
Please wear gloves to remove the parts from the printer.
Clean the printed parts before post curing. Use solvents recommended by the manufacturer, such as isopropanol or topical alcohol.
Use UV recommended by the manufacturer for post curing. Before post curing, the parts should be cleaned, and the cleaned parts should be able to be directly touched by bare hands.
According to the printer manufacturer’s recommendations, ensure that all 3D printed parts are subjected to ultraviolet radiation and thoroughly cured after molding.
4、 Personal hygiene guidelines
Eating, drinking, or smoking in the work area is prohibited. Before processing uncured UV resin, please remove jewelry (rings, watches, bracelets).
Avoid direct contact between any part of the body or clothing with UV resin or surfaces contaminated with it. Do not touch photosensitive resins without wearing protective gloves, nor allow skin to come into contact with resins.
After the operation, wash your face with cleanser or soap, wash your hands, or any body parts that may come into contact with UV resin. Do not use solvents.
Remove and clean contaminated clothing or jewelry; Do not reuse any contaminated personal items until thoroughly cleaned with a cleaning agent. Please discard contaminated shoes and leather goods.
5、 Clean work area
UV resin overflows, immediately clean with an absorbent cloth.
Clean any potential contact or exposed surfaces to prevent contamination. Clean with window cleaner or industrial alcohol or isopropanol, then thoroughly clean with soap and water.
6、 Understand first aid procedures
If UV resin enters the eyes and comes into contact with the skin, rinse the relevant area thoroughly with plenty of water for 15 minutes; Wash the skin with soap or a large amount of water, and if necessary, use an anhydrous cleaner.
If skin allergies or rashes occur, seek qualified medical assistance.
If ingested accidentally, do not induce vomiting and seek medical attention immediately.
7、 Disposal of photosensitive resin after printing
Thoroughly cured resin can be treated together with household items.
UV resin that has not been fully cured can be exposed to sunlight for several hours or cured by irradiation with a UV light source.
Partially solidified or uncured UV resin waste can be classified as hazardous waste. Please refer to the chemical waste disposal regulations of your country or province and city, and dispose of them according to the corresponding management regulations. They cannot be directly poured into the sewer or water supply system.
Materials containing UV resin must be treated separately, placed in sealed, labeled containers, and disposed of as hazardous waste. Do not pour its waste into the sewer or water supply system.
8、 Correct storage of UV resin
Seal the UV resin in a container, avoiding direct sunlight, and store it according to the manufacturer’s recommended temperature range.
Keep a certain air layer on the top of the container to prevent resin gel. Do not fill the entire container with resin.
Do not pour used, uncured resin back into a new resin bottle.
Do not store uncured resin in refrigerators for food and beverages.
