About Resin

Resin 3D printing uses photopolymer resin that hardens under UV light. This so called “hardening” is when the material is transformed from liquid state to solid. The resin is chemically different than polystyrene plastic found in injection-molded plastic kits and so needs to be treated differently.

Resin models produce much finer results than filament printing. However, resin can be more fragile so more care is needed.

Ordinary modelling glue is not suitable for resin. The best glue to use is a quality Super Glue (Cyanoacrylate), Gorilla Glue (Micro Precise) or Resin Epoxy Glue.

If a resin part becomes bent or warped, then heat the piece with a hairdryer or in very hot water. It will make it flexible, and you can effortlessly re-shape it, but be gentle. After cooling it will keep the new shape. This process may need to be repeated many times to get the shape you want. Never continue to try and shape the resin once it starts to cool, as it will break.

Continual exposure to UV light will make the resin more brittle. Due the nature of curing resin, some smaller parts will be more brittle and some of the larger parts slightly softer (this is hardly noticeable).
Resin can warp easily. If left in direct sunlight it may warp.

Resin is not suitable for very young children or pets.
