3Dresyn 2PP IM-H-FAS Bio, Fast Acetone Soluble photopolymer for printing sacrificial materials with two photon polymerization

3Dresyn 2PP IM-H-FAS Bio is a hard biodegradable bio based photopolymer for two photon polymerization.

It is designed as a negative photoresist for slow-medium writing speed additive manufacturing of acetone soluble sacrificial 3D nano and microstructures, offering an excellent balance of resolution and writing speed.

Designed for two photon polymerization workflows, including Dip-in two-photon lithography DTPL / Dip-in Laser Lithography DiLL and conventional Two Photon Lithography TPL configurations, for fabrication of acetone soluble sacrificial 3D nano and microstructures.

• Photoreactive from 600 to 810 nm with Fine Tuner 2PP FT8 Bio (two photon absorption)
• Medium hardness
• Clear

• 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 microscope 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
• Excellent adhesion on glass and other substrates
• 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 viscosity version (<2000 mPas) for easy development or cleaning of uncured resin with conventional 2PP upright configurations
• Easy removal of uncured resin with conventional developers such as 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

• Biocompatible
• Over 80% bio based content
• Soluble in acetone
• Organo-tin free

Final writing speed, resolution, feature size, adhesion, printability, solubility and cleaning performance depend on the printer configuration, wavelength, substrate, developer and full processing workflow. Performance must be validated by the user for each specific application.

This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
