3D Pen

[kiwi_al]

Has anyone tried a 3D Pen ? , looks like it might be useful for repairing 3D printed shells if you have a wobbly moment getting the shells off the raft.

I have not tried one.  The filaments they use are listed at 1.75 mm, which is 11" in N scale.  I don't know what is the smallest dot you can make with one. I would like to make N scale things about 1/10th that filament size.

The easiest way to fix what you describe is to make or buy a UV pen, fill the broken part with the same resin used fo the print, and hardening this with the UV pen.

I hadn't thought of that , makes a lot of sense - doh!!

I use the JB Weld UV glue all the time. Pick them up at Lowes or Menards.

Yes, but I will tell you, the Printer resin is 100% better- thinner, cures quicker when applied and fills divots better.  The other nice thin is that the resin does not harden on its own.

I will be doing a writeup on it here soon.

You can even make much larger assemblies than what can be printed in your print envelope this way. Print out smaller segments of your model and "weld" them together with a bit of liquid resin, cured with a UV pen/flashlight. Works great, and the welded area is as strong as the parent material, as it is the same material.
