Fine Tuner LB1 Bio, hydrophilic biocompatible resolution-er for improving resolution
Product description
Fine Tuner LB1 Bio is a clear resolution additive developed to improve XYZ resolution by reducing overcure of prints beyond specifications of our resins in SLA DLP & LCD printers working with lights from 350 to 410 nm, including 405 nm blue LEDs, lasers and standard DLP projectors and LCDs.
It is a 100% safe hydrophilic biocompatible resolution-er with a Material Safety Data Sheet "MSDS" free of hazards and pictograms. It is recommended for reducing Light Bleeding (LB) or undesired overcure in engineering and biomedical applications where the highest hidrophilicity, safety and biocompatibility standards are required.
Application framework
Designed for fine tuning 3D resins in SLA, DLP and LCD printers working with lights from 350 to 410 nm, including 405 nm blue LEDs, lasers and standard DLP projectors and LCDs, to reduce Light Bleeding (LB) or undesired overcure and improve resolution and accuracy according to specific printer settings.
Typical applications
- Reducing Light Bleeding (LB)
- Reducing undesired overcure in engineering applications
- Reducing undesired overcure in biomedical applications
- Improving XYZ resolution of prints
- Improving resolution and accuracy of prints in specific printer settings
Measured physical properties
- Clear additive
- Hydrophilic
- Recommended for printers having UV/Visible light wavelengths up to 410 nm (350-410 nm range)
Functional performance characteristics
- Improves XYZ resolution
- Reduces overcure of prints beyond specifications of resins
- Reduces excessive light penetration (Z axis) and/or scattering (XY axis)
- Fine Tuner LB1 Bio is as effective as Fine Tuner LB1 Bio ULWA and can be exchanged since both have the same performance yield as resolution-ers
- Fine Tuner LB1 Bio 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 for use in steps of 0.5% to improve the resolution and accuracy of prints in specific printer settings
- 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
- Applied Engineering Analysis
- Cure Kinetics & Working Curve
Chemical and safety characteristics
- 100% safe
- Hydrophilic
- Biocompatible
- 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.
