Hot Glue Casting: Instructables Robot {L.E.D. Backlit}

Featured
This Instructables is not only about The Instructables Logo - The Robot, But it also about HOT GLUE CASTING!!!...It shows you how you can make your very own Instructables Robot model!!!.. Which could also double up as a cool night light!..

After seeing one too many instructables on How to make the instructables robot, I have been wanting to make one of my own, in my very own way!!!

Now, hot glue is used as an adhesive by most people, but I decided to use it as a casting material... and It turned out really great!!!...

For some amazing pics of it, roll over to the last step!!!... :D

If you have molds of everything, you can mass produce.

Very cool idea. Since I didn't see it in the materials list: what kind of oil did you use? I'm planning on doing this for a project of my own. Though I'm using plywood as the thing I'm casting in and so I don't know that oil is even what I'd want to use on that, but I'm still curious.
Siddharth Jain (author)  khietman2 years ago
Well I just used the mustard oil...but I think any other vegetable or machine oil shall do the job equally well!..(I'd prefer machine oil though with plywood...).... :D

Can't wait to see your results!!!!!..... :D

cheers!.... :D
This gives me sooo many ideas... Just a quick question. How many hot glue sticks did you use? And the glue won't stick to the tape?

Great job!

I just used around 8 glue sticks of 11 inches each....
2 for the head, 2 for hands and legs and the remaining for the body.....

well, it might tend to stick to tape if no proper oiling/lubrication is done....

:D Thanks!!!... :D
