Fine Tuner LB2 Bio ULWA, resolution-er for improving resolution with no fluorescence and ultra low water absorption

Product description

Fine Tuner LB2 Bio ULWA is a clear resolution additive developed to improve XYZ resolution by reducing light penetration, scattering and overcure of prints beyond specifications and "support fusing or merging" of our resins in SLA DLP printers working with 365 and 385 nm, from 350 to 390 nm.

Fine Tuner LB2 Bio ULWA is a 100% safe biocompatible resolution-er with no fluorescence and with ultra low water absorption (ULWA: <15 µg/mm3), ideal for Microfluidic applications, and with a Material Safety Data Sheet "MSDS" free of hazards and pictograms. It is recommended for reducing Light Bleeding (LB) or undesired overcure in biomedical applications where the highest safety and biocompatibility standards are required.

Application framework

Designed for fine tuning 3D resins in SLA DLP printers working with 365 and 385 nm, from 350 to 390 nm, to reduce Light Bleeding (LB), undesired overcure, light penetration and scattering, and improve resolution in biomedical and microfluidic applications.

Typical applications

• Reducing Light Bleeding (LB)
• Reducing undesired overcure in biomedical applications
• Improving XYZ resolution of prints
• Microfluidic applications
• Increasing print resolution when printing clear and colored resins with SLA DLP 3D printers

Measured physical properties

• Clear additive
• No fluorescence
• Ultra low water absorption
• Compatible with SLA DLP printers working at 365 and 385 nm, from 350 to 390 nm

Functional performance characteristics

• Improves XYZ resolution
• Reduces light penetration and scattering
• Reduces overcure of prints beyond specifications
• Reduces "support fusing or merging"
• Essential for increasing the print resolution when printing clear and colored resins
• Fine Tuner LB2 Bio ULWA tends to crystallise naturally
• A gentle warming (use microwave with extreme caution, water bath is best) and shake will redissolve the crystals
• Alternatively, it can be shaken by hand at room temperature to make a homogeneous mixture which can be added directly to the resin

Processing and handling performance

• Recommended use in steps of 0.5% to reduce gradually light penetration and avoid overcure
• Use in steps of 0.5% until the depth of cure at long times (eg 100 seconds) is below 2-3 times the chosen z layer for printing
• Supplied as a kit, which contains the product, one graduated beaker and one empty 250 mL black bottle to measure, mix, keep and protect the 3D resins from daylight
• Please do not expose any 3D resins to natural or room light to prevent their curing

Chemical and safety characteristics

• 100% safe
• Biocompatible
• No fluorescence
• Ultra low water absorption (ULWA: <15 µg/mm3)
• Material Safety Data Sheet "MSDS" free of hazards and pictograms

Testing & processing disclaimer

If you are not fully satisfied with the resolution of your prints it is necessary to fine tune our resins to your printer settings.
