FormFutura® Engineering LCD Resin – Flex 82A

Our Engineering LCD Resin - Flex 82A is a soft-touch 3D printing resin with rubber-like properties. This engineering resin has material properties like TPU with a shore hardness ranging from 82A to 87A. The combination of semi-flexibility with strength makes this Engineering LCD Resin - Flex 82A a versatile material for various applications. Parts 3D printed with this resin show a good resistance to repeated exposure to compression, bending and flexing.

Important key features

• 3D printing resin with rubber-like material properties.

• Good resilience to bending, flexing, and compression.

• Excellent material specifications with respect to damping and shock absorption.

• Good compatibility with all SLA, DLP and LCD / MSLA 3D printers in the range of 385 – 420nm.

Suitable applications

• Perfectly fit for manufacturing seals and gaskets.

• Suitable for creating wearables and soft-touch applications.

• Perfect for producing mechanical and operational replacement parts.

• Excellent material for making handles and grips.

• Perfect for short-run manufacturing

Preparation(s) before starting to print

• Shake the bottle for at least 2 minutes before each use.

• After shaking the bottle, leave the resin to rest for 10 minutes to let air bubbles get out of the resin

• The resin can be poured back from the vat into the bottle once your print is finished

• Always use protective measurements like safety glasses and nitrile gloves when handling resins.

Post-processing

• We do advise you to post-process your 3D print in order to achieve the material properties

• Rinse your 3D printed object in IPA or (Bio)Ethanol for approximately 5-10 minutes

• An ultrasonic cleaner is preferred/recommended

• Make sure that IPA and/or (Bio)Ethanol rinsed objects are perfectly dry before further post-curing to prevent warping or cracking.

• Place the rinsed parts in a well-ventilated area for at least 4 hours, or use pressurized air for at least 5 minutes

• Cure your object in a high power curing chamber (like the CUREbox™ Plus) for approximately 60 minutes at 65°CAnd after that approximately 2 hours of thermal curing at 100°C. The preferred curing wavelength is between 300-410nm

Safety

Please always be aware that when 3D printing with resins that you are working with chemicals and that you should always be cautious and use the personal protective equipment as stipulated in our safety data sheets.

• Always wear Respiratory Protection when sanding/cutting the resin object.

• Always use nitrile gloves when handling resins and uncured resin objects.
