3Dresyn IM-UHR-WS has these features and benefits:
- recommended for printing Water Soluble WS sacrificial Injection Molds IM for injection of low, medium and high injection pressure & temperature materials, plastics, ceramics CIM and metals MIM
- ultra hard and ridid UHR, Shore Hardness D80
- high rigidity at high temperatures (>120C)
- fast solubility in water
- tack free finishes after light box postcuring
- very high tensile strength >40 MPa
- very high rigidity (Young modulus >2500 MPa) to permit printing of thin rigid mold walls to maximise solubility speed and minimum resin consumption
- non brittle at injection temperatures
- elongation <5%
- very low viscosity, below 100 cps
- very high resolution (printing resolution of 20 microns)
- very low shrinkage
- printable by most commercial and professional SLA, DLP & LCD 3D printers
- improved water solubility is achieved with low light power printers, such as standard LCD printers
- increased durability of the resin tank
- metal and organo-tin free
Note: water soluble 3D prints can be cleaned and postcured in few steps:
- step 1 optional but recommended: remove any uncured resin from the print surface with high pressure air with at least 10 bars (the higher the better)
- step 2 remove any uncured resin from the print surface with our Cleaning Fluid WS2
- step 3 Light postcuring in a light box by dipping the cleaned prints in fresh Cleaning Fluid WS2
- 5-10 minutes is enough to get a dry surface
- 20 min will increase the rigidity of prints (recommended)
- 60 minutes will increase the rigidity of prints to its maximum but certain brittleness will appear due to excessive light postcuring
