Hi,

We are looking for a strong glue to attach 3D printed parts together, our main requirements are that it is environmentally friendly and is strong. It will not be subject to huge amounts to drops and pressures but it has to withstand normal everyday abuse.

The item which we require the glue for will be used during scuba diving, hence our requirement for environmentally friendly glue.

Thanks for your help

One of my favorite ways to glue PLA parts is using PLA itself, from a 3d pen.

Similar to Perry’s idea is Friction welding, Joel Telling has a video on this here:
