Technical Data Flexible DL220B Print sample Compatible Printers Liquid Crystal Colours Black Translucent Introduction Creating complex geometries like lattices, with ‘Flexible’ materials, allows the user to maximise the benefits of 3D printing, making a part with dynamic properties with only one step manufacturing instead of several. Photocentric is introducing its first ever industrial Daylight Flexible Resin- ‘Flexible DL220B’ – an optimised solution for applications which require a combination of impact absorption, high elongation, efficient energy damping, good tear strength and exceptionally low water absorption. Printing of flexible materials has never been easier, owing to its superior green strength and excellent definition. Best Used for: • • • • Sport protection, e.g., shin pads Shock and impact absorption, e.g., phone cases Cushioning Vibration damping, e.g., industrial machinery feet Unique Features: • • • • • Remarkable elongation at break >200% Slow rebound and efficient energy damping Exceptionally low water absorption (<1% after 7 days) High definition and resolution Easy to print due to its high green strength UK Titan House, 20 Titan Drive, Peterborough, PE1 5XN. email: [email protected] USA Avondale 107 - Building ‘A’ 855 N. 107th Ave., Suite A110, Avondale, Arizona 85323 email: info@photocentricusa.

Technical Data Design & Print Consideration Parameters Minimum feature size (pins) Minimum hole diameter Minimum slot thickness Minimum wall thickness Minimum wall thickness unsupported Minimum wall thickness unsupported can be 2mm, while the Z built height should be <60mm Or can be 3mm, while the Z built height should be <110mm Scaling factor Lattice Parameters Photocentric Applications team designed the following different lattices test piece as a recommendation for user’s first print with any flexible resin. By doing so, user will understand resin properties in relation to design parameters...

Technical Data Pre-Print Instructions • To print with Photocentric Liquid Crystal Magna, choose ‘Flexible DL220B’ at desired layer thickness when preparing your print file in Photocentric Studio. Heat the resin to 30°C in the bottle. Shake the resin bottle for 2 minutes before pouring into the resin vat. o Shaking the resin before it’s poured into the vat ensures pigments and other constituents of the resin are evenly dispersed. Post Processing 1- Parts can be washed in ‘Photocentric Air Wash L’ for no longer than 15 minutes using ‘Photocentric Resin Cleaner’ or ‘Photocentric Resin Cleaner 30’....
