Welcome to my instructable on how to make a very stylish lamp out of a potentially un-stylish material - concrete! To be honest, style (or rather beauty) is in the eye of the beholder and so I'll leave it up to you to decide if it fits in your surroundings or not. What do you think?

All the necessary steps are here but if you don't like reading the just sit back, relax and watch the video instead. Please also subscribe to my YouTube Channel where you find lots of videos on projects and repairs.

When I said to people at work that I was making a concrete lamp the first expectation/question was "is it for outdoors". In this case, emphatically no! It is very much an indoor lamp which has the harshness of the concrete and the softness of the light - a combination that I think works well in this case.

But how to make it?!

The concrete body of the lamp (which, to my eye look a bit like a leek) is made is two halves. The 1st and 2nd halves are cast in 2 steps using the same mould twice. I had a few failed attempts at making the mould entirely from standard PVC pipe but they were epic fails - see the last step for a video of my epic fails. I ended up designing a number or parts to use as a mould and printing all the parts out on my 3D printer. I've since used the parts a few times so they are perfectly reusable. Similarly the base (support) to the concrete is made on the 3D printer. If you don't have access to a 3D printer the these 2 parts could be made using other materials such as wood or metal if you have the equipment (Lathe probably).

The finishing is fairly basic - just spray paint the exposed plastic base and wire in a lamp holder. This builds can be done with minimal tools (except for the 3d printer -sorry) and limited manual skills - Go on have a go!

NB: For the American English speakers......Mould=Mold, I'm from the UK!

Step 1: Tools and Equipment

Picture of Tools and Equipment

As I finished up saying in the introduction, you will need a 3D printer to complete this build. However, as this piece of equipment has already made and appearance in many hobbyist workshop I'm hoping this isn't an impediment to you completing this project. However, if you have yet to take the plunge maybe this is the time to do so!

FYI = I have a Lulzbot mini - its not a large machine and indeed I had to split part of the mould into 2 separate pieces to enable the printer to print them.

Aside from the printer very minimal tools are required.

1) An old bucket and trowel to mix the concrete - the volume is very low so only a small container is required

2) Cable preparation and installation will require only the basic of tools such as a knife and screwdriver

Very fun lamp design! I agree with Seamster, the flexible shape is very appealing to see in concrete :)

Thanks Penolopy - I'ts my first time using concrete as a project medium....I think I may have another few designs I'd like to try! Thanks for the comment.

This is a great design. The appearance of a flexible shape but cast in concrete creates a nice mental conflict. Great execution too. I like it! :)
