Introducing Blu by Siraya Lab, an easy to use tough resin that performs under stress. It balances between strength and hardness and is ideal for making functional parts that are strong yet with some flexibility.

Unlike many resins on the market that are too brittle to handle even the slightest drop, Blu has excellent mechanical properties that can withstand forces without breaking easily.

We were able to make a hook with it and pull up 20kg weight without breaking. Imagine the kind of projects you can do with it.

Blu has been used on Anycubic Photon, Zortrax Inkspire, Wanhao D7, Phrozen Shuffle and Xl, Dazz and other LCD printers. (not developed for laser SLA)

Blu is now certified as biocompatible for external skin-safe application under ISO 10993-10 standard, check here to view. To achieve biocompatibility, the user must follow the cleaning and curing procedure listed in the user guide.

Unlike many engineering resins, it is very easy to clean with common alcohols and post cures quickly as well. It has excellent resolution, primes well and is used by model makers to create sculptures as art pieces. And it does not smell so it wouldn't stink up your workplace.
