3D resin handling and waste disposal

Our 3D resins are safe* if used as per our instructions for hobby, professional printers and final users.

Most of our 3D resins are ultra safe and include 3D resins which do not contain any monomers as supplied. Our ultra safe 3D resins have been designed to meet the highest safety and biocompatibility standards. These products are non labeled with toxic pictograms because they are ultra safe for handling, end users, and disposal. Most competitor´s 3D resins contain toxic ingredients which can cause health problems, since they can be absorbed by the skin. Some resins emit toxic fumes which can also cause health issues.

3D RESIN SAFE HANDLING & WASTE DISPOSAL

3D resins for 3D printing cure fast and release heat when exposed to UV & Visible light and high temperatures, consequently 3D resins need to be handled carefully. 

MATERIAL SAFETY DATA SHEETS MSDSs

  • First of all, read always the MSDSs of all the products that you will use, including but not limited to 3D resins, additives, and auxiliaries, before using them as the main source of safety documentation to prevent any potential risks and hazards 

SAFETY BASICS

  • Do not eat, drink or smoke in the working area
  • Always wear gloves and avoid direct skin contact with 3D resins, prints before cleaning, and with contaminated surfaces and materials
  • Rinse and wash hands, face, eyes, and any part of the body which was in contact with 3D resin
    • rinse with plenty of water for some minutes followed by washing with a mild soap
  • Remove and wash contaminated clothing
  • Do not reuse any contaminated clothing  

PERSONAL PROTECTIVE EQUIPMENT 

  • Wear always gloves and safety glasses / goggles with UV & Near Visible protection to protect your eyes, since most printers work with UV, near UV & Visible light wavelengths from 360 to 405 nm
  • Wear a dust mask when sanding prints
  • Wear a respirator mask with organic solvent filter when using high odour "stinking" 3D resins
    • Not needed with our 3D resins since are Volatile Organic Compound "VOC" free

BASIC PRINTING PROCEDURES

  • Keep clean and safe working conditions
  • Do not expose liquid 3D resins as supplied to heat above 80°C to prevent their premature thermal polymerization or curing (exothermic reaction)
    • custom designed 3D resins can be stabilised to withstand high temperature
  • Do not expose liquid 3D resins as supplied to flames, sparks or any source of ignition
    • particularly crucial when using 3D resins containing VOCs
  • Do not expose liquid 3D resins as supplied to light to avoid their premature cure in the original container or in the resin tank
    • to prevent their photopolymerization or curing (exothermic reaction)

BASIC POST PRINTING & POSTCURING PROCEDURES

  • Wear gloves when handling parts directly from the printer
  • Clean prints before postcuring with safe non flammable cleaning fluids
  • Postcure prints in a light box UV light as recommended in 3D resyns Instructions for Use IFU
  • Ensure that 3D prints are cleaned and fully cured before use
  • Ensure that biocompatible 3D prints are fully cured and cleansed
    • Ensure that leachables and extractables are removed before use

CLEAN UP WORK AREA

  • Clean any exposed surfaces to prevent contamination
  • Clean with non flammable cleaners, such as 3Dresyns cleaning fluids
  • Use absorbent paper towels to clean spills

FIRST AID PROCEDURES

  • Rinse exposed eyes or skin thoroughly with plenty of water for 15 minutes
  • Wash skin with a mild soap and plenty of water
  • If strong skin irritation or rash occurs, read the MSDS for advice and seek qualified medical attention
  • If ingested, do not induce vomiting. Seek medical attention immediately

STORAGE

  • Keep 3D resins sealed tightly in the original containers as supplied, or in opaque black containers, out of direct sunlight or office light, ideally at room temperature or cold, but always below 50ºC to prevent their premature thermal and photo curing
  • Do not pour used, uncured resin back into new resin bottles to prevent cross contamination
  • Do not store 3D resin in refrigerators used for food and beverage storage

WASTE DISPOSAL

  • Fully cured 3D resins can be disposed of as solid plastic household items
  • Cure liquid 3D resins in a clear container with sunlight or in a light box for few hours until bulk solidification
  • Liquid 3D resin waste may be classified as hazardous waste, consequently it needs to be disposed in accordance with your local applicable regulations
    • normally it can be classified and disposed as and with solvent based paints, enamels, and varnishes 
  • Do not pour liquid 3D resins into the sink, down the drain or into a creek, river, or other body of water without treatment
  • Water used for dissolving water soluble prints can be filter or evaporated. The resulting solid or gellatine residue can be cured under light and disposed as and with water based paints, enamels, and varnishes   
REUSE
  • How to reuse dirty cleaning fluid? Expose the Cleaning Fluid in the washing container to sunlight, or with or without stirring to light in the light box or curing machine. After several minutes the uncured resin dissolved in the cleaning fluid will cure as small particles. Then, use a paint filter to separate and remove the cured resin from the recycled cleaning fluid, which can be used again and again for washing prints.
  • How to reuse dirty 3D resin? Filter dirty resin with a disposable paint filter to remove any solids debris. The filtered resin can be reused.

*Note: some resins can/may cause skin and eye irritation and other hazards (read the MSDS of each material before handling them)
