3Dresyn 2PP PDMS-like MF Bio, Biocompatible Monomer Free flexible silicone-like photopolymer for two photon polymerization

3Dresyn 2PP PDMS-like MF Bio is our Biocompatible Monomer Free flexible silicone-like photopolymer for two photon polymerization.

Features and Benefits:

• ideal 2PP biocompatible & bio-based photocurable resin (negative photoresist) for fast writing speed additive manufacturing of biocompatible flexible silicone-like 3D nano & microstructures
• 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  
• flexible 
• 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 A90 (D40) (macroscale): softer in nanoscale
• clear
• tensile strength, <20 MPa  (macroscale): less resistant in nanoscale
• flexural strength <20 MPa  (macroscale): less resistant in nanoscale
• rigid (Young modulus <100 MPa)  (macroscale): more flexible in nanoscale
• elongation <100% (macroscale): more elastic in nanoscale
• biodegradable
• low shrinkage <2%
• 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 
• tunable with the free sampled Fine Tuner 2PP FT8 Bio for custom adjustment of writing speed
• tunable with the free sampled Fine Tuner 2PP LB3 Bio for maximum resolution with submicron feature sizes 
• 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
