Ultracur3D® EL 4000 (90A) BASF - 1000 ml

Use of BASF Ultracur3D EL 4000 resin

The Ultracur3D EL 4000 resins developed by the manufacturer BASF are photo reactive urethane resins developed for DLP/LCD and MSLA technology.

The EL series is the most flexible and durable, suitable for applications requiring high performance. Ultracur3D® EL 4000 from Forward AM is a highly versatile photoreactive urethane polymer for highly elastic applications that offers medium hardness(Shore 90A). It offers an optimum combination of performance: high torsional strength, good elongation at break and high long-term rebound.

EL4000 resin: key strengths

Versatility: Soft, flexible and elastic up to 172%, it also has superior hardness, making it ideal for the most technical applications. It develops unique performances such as a rare compromise between strength, elongation and springback.

Elasticity: Urethane resins offer precision and excellent stability, and this remains true of this highly elastic resin. A high rebound rate but less durable compression resilience.

Hardness: Its shore hardness of 90A is quite rare for a flexible resin, especially when combined with this high level of elasticity.

Our recommendations for use with EL4000 resin

Ultracur3D resins are particularly sensitive to UV. Be sure to protect them from light as soon as they have been opened. It is also always advisable to wear gloves when handling them.

Shake your bottle of resin before use and leave it in the print tray for a few moments before use. To determine the best exposure time for your 3D printer model and technology, don't hesitate to consult our guides and our community.

The last stage in the manufacturing process is to clean your part in alcohol such as IPA or a suitable BASF Cleaner solution, followed by a quick run in the UV chamber to stabilise your print for good and get the best performance from your printed part (around 20 minutes depending on size and thickness).
