3Dresyn 2PP XL2 Bio is our biocompatible fast and rigid crosslinker for increasing the rigidity, Heat Deflection Temperature HDT, and the aspect ratio without deformation of 2PP 3D resins.
Its use increases the writing speed of slow 2PP resins, as well as their rigidity, hardness, physical and mechanical properties, such as deflection temperature, compression and chemical resistance. It also decreases the laser power threshold and permits the printing of high detail and high aspect ratio nano and submicron structures with even low laser powers of <10 mW.
Our 3Dresyn 2PP XL2 Bio is normally used up to 5-15% dosage (or more depending on rigidity specifications for certain nano thickness) and it is used for custom adjusting the rigidity of any 2PP 3Dresyn.
Features and Benefits:
- ultra effective crosslinker: minimum dosage is required for increasing rigidity and deflection temperature
- ideal used alone as 2PP biocompatible photocurable resin (negative photoresist) for high precision additive manufacturing of ultra rigid high aspect ratio 3D nano & microstructures with ultra high rigidity and 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
- 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

- ideally use our biocompatible Cleaning Fluid UNW1 Bio to preserve transparency, prevent whitening and chemical attack of IPA and conventional alcohols
It is supplied as a kit, which contains the product, one graduated beaker and one empty 100 mL opaque bottle to measure, mix, keep and protect 2PP 3D resins from daylight. Please do not expose any 3D resins to natural or room light to prevent their curing.
