3D resins for printing sacrificial molds

Our selection of sacrificial 3Dresyns and special additives for 3D printing sacrificial models and molds for injection of traditional materials such as waxes, silicones*, plastics, ceramics and metals feedstocks.

Our sacrificial SLA DLP and LCD 3D resins can be sacrified or eliminated by:

  • dissolution in water or alcohols with our heat resistant water soluble resins 3Dresyns IM WS product range for printing high deflection temperature water soluble sacrificial materials (individual products are shown in the icons below) and 3Dresyn Perfect Cast WS1 , which are ideal for injection of plastics, ceramics, metals and for jewelry and electroforming /electroplating 
  • dissolution in solvents with our hard 3Dresyn IM-H-SS Bio and our flexible 3Dresyn IM-F-SS Bio which ban be combined for custom rigidity adjustment of solvent soluble 3D printed resins for printing non water soluble sacrificial materials
  • by heat/melting with our heat soluble or meltable 3Dresyn Perfect Cast HS1 , which is ideal for jewelry and electroforming /electroplating
  • breaking them easily by hand with our easy breakable 3Dresyn IM-SF Cocoon and with our ultra safe and monomer free 3Dresyn IM-SF MF Bio Cocoon which is ideal for injection of soft materials such as silicones

Sacrificial technology is ideal for engineering, industrial and dental applications since traditional dental materials can be easily  injected by gravity or under pressure in heat resistant water soluble sacrificial molds printed with our sacrificial 3D resins with even low cost LCD 3D printers.


Our 3Dresyns IM-WS have been designed for printing 3D printed Injection Molds IM with very high resolution for injecting/casting of:

  • silicones*
  • waxes such as our 3Dresyns Waxes
  • low, medium and high injection (processing and/or curing) temperatures up to 200C or higher, for injection of traditional materials such as:
    • plastics such as our new Resin Injection & Casting 3Dresyns, which are light and/or heat curable biocompatible resins or 
    • polyurethanes for making aligners with the benefit of reducing production costs (laser cutting is not required)
    • nylon (polyamide 12) for making partial flexible dentures
    • PMMA for making rigid denture bases 
  • ceramic feedstocks (Ceramic Injection Molding CIM) such as our Ceramic 3Dresyns slurries
  • metal feedstocks (Metal Injection Molding MIM)  such as our Metal 3Dresyns slurries

The usage of sacrificial 3D resins is ideal for engineering and  industrial applications, such as injection of Ceramics and Metal slurries used in CIM and MIM applications. Other applications such as Electroforming can be used for replacing the expensive multi step prior electrodeposition. Mandrels can be printed with our water soluble sacrificial 3D resins and dip coated with our conductive resins. After electrodeposition of metals such as gold, mandrels can be easily dissolved in water.


  • Fine Tuner FT1 is our preferred photo accelerant to adjust print speed to your printing specifications
  • Fine Tuner LB Cyan is our preferred cyan colored resolution increaser for improving resolution and fine detail printing without reducing water solubility
  • our consultancy for customised Full 3D Printing Systems includes all the required instrumentation (3D printer with radiometry, light power and temperature control, washing and postcurintg units and all the basic tools and training for start printing straight away.
  • soft and delicate castings can be injected also in easy breakable sacrificial molds 3D printed with our : soft and easy breaking  SLA, DLP & LCD 3D resins

    Dissolution process in water in 3-6 hours (dependent on thickness) of 3D printed water soluble resins 

    Clean and postcure your water soluble 3D prints with Cleaning Fluid WS1 and Cleaning Fluid WS2 Bio.

    Note: Isopropanol and/or water cannot be used for cleaning water soluble sacrificial 3D printed resins since they will dissolve them during the cleaning process!!

    *Note: Injected molded RTV silicones use platinum catalysts, which are inhibited by some chemicals contained in 3D printed molds, leaving the surface of the silicone sticky or uncured. Full curing is required to avoid the risk of monomer extraction and silicone curing inhibition. The use of our Cleaning Fluid, Cure Tester and Purification kit also help to overcome this common problem, by eliminating the inhibiting chemicals from the surface of 3D printed molds.
