3Dresyn 2PP HAR2 Bio is our Biocompatible High Aspect Ratio ultra rigid photocurable resin with ultra high High Deflection Temperature for two photon polymerization.
Features and Benefits:
- ideal 2PP biocompatible photocurable resin (negative photoresist) for high precision additive manufacturing of ultra rigid high aspect ratio 3D nano & microstructures with ultra high deflection temperature
- excellent balance of resolution (shape accuracy) and writing speed
- photoreactive from 200 to 410 nm with Fine Tuner 2PP FT8 Bio (single 1 photon absorption)
- photoreactive from 600 to 810 nm with Fine Tuner 2PP FT8 Bio (two photon absorption)
- 100% optically transparent from 440 nm onwards into the Near Infrared NIR
- achievable feature sizes of 100-200 nm
-
designed for Dip-in two-photon lithography DTPL (also referred as Dip-in Laser Lithography DiLL) where the 2PP resin is immersed upside down in the microcope objective
- designed for conventional 2PP systems (also refered as Two Photon Lithography TPL) where the 2PP resin is positioned upright on the substrate
- ultra rigid
- easy handling by direct drop casting
- biocompatible
- good adhesion on glass and other substrates
-
safe and biocompatible, compliant with the Quality requirements of FDA, ISO 20795, 13485 & 10993
- synthetic
- very low water absorption: <15 µg/mm3
-
water solubility: ≤ 1,6 µg/mm3
- hydrophobic
- Shore hardness D90
- clear, non yellowing
- tensile strength, <40 MPa
- flexural strength < 40 MPa
- ultra rigid (Young modulus 4000-6000 MPa)
- high deflection temperature >290ºC
- elongation <1%
- durable
- medium shrinkage <13%
- organo-tin free
- printable by most commercial two photon polymerization printers with wavelengths from 600 nm to 800 nm
- supplied at different writing speeds: fast, intermediate, slow, and non reactive for custom control of writing speed and resolution
- supplied in a relatively low and high viscosity version
- choose a LV low viscosity version (<1000 mPas) for easy development or cleaning of uncured resin with conventional 2PP upright configurations
- choose a HV high viscosity version (>2000 mPas) for upside down DiLL configurations
- easy removal of uncured resin with conventional developers such isopropanol IPA and propylene glycol methyl ether acetate (PGMEA)
- ideally use our biocompatible Cleaning Fluid UNW1 Bio to preserve transparency, prevent whitening and chemical attack of IPA and conventional alcohols
