I think canreef has quite a few 3D printers. It depends on how complicated the model and depending on the geometry, you can convert real life ideas to printed objects fairly easily.

Stereolithography is the main issue and I can see why. It uses a very unique form of resin and can definitely contain toxic. I am not sure whether any of the resins are FDA approved.

On the other hand, plastics like ABS and PETG are very common and FDA approved. In fact, they are used in quite a few aquarium components too. Sometimes the colour compounds can release unwanted chemicals so people stick to neutral colours. Alongside, FDM printers have 10+ types of plastics now and the researchers did not mention which plastic they tested.

People have been used ABS printed frag racks, etc. for years without any issue so I don't see anything to be concerned about.

Just saw on FB a new "pancake" 3D printer, that uses pancake batter instead of plastic or ink to create the design off a picture or file.

Ive been picking up Dollarama Superglue for making frags and plugging up pest anenome holes.

I always did that too, but I learned that a bottle of coral glue will out last 100 tubes of the dollar store stuff. So even though it's hard spending $25 on a bottle of glue, it last way way longer.

Couldn't agree more, thought dollar store crazy glue was about the best deal ever compared the fish store but damn those little tubes barely have anything in them either.

Geat idea thanks for this. Picked up a $15 oral b one yesterday and used it. Totally waterproof and the small rotary head gets into all the hard to reach places.
