A 3D topo map out of MDF

Postby jscook55 » Sun May 13, 2012 6:46 pm

Got done with this MDF 3D topo map of Ross Island a while ago. Made a mistake on one of the elevation changes, but turned out pretty well otherwise:

Oh boy ... you should see my garage ! I do these for fellow architecture students often. For a quick and easy one I use insulation foam as a quick and easy material. Generally a good finish and you can cut it as fast as you like.

For really good looking topographic cuts though try using a good looking ply - I really like the ones with a dark epoxy. It gives a strong definition to the layers and emphasizes the contour lines in the result. I'll post some pics next time I do a ply one.

Nice! I'll have to try that, getting a bit bored with MDF. Would love to see your stuff!

Yeah, I am terribly slack taking photos and I haven't done one for myself yet as I'm always running so late I only have time for foam. I must try to get some of the ones I've done off other students. Next semester I hope to have the big brother CNC going so I can do 1200x600mm models!

I found some stuff at my local plastics dealer called SINTRA it is a closed cell expaned PVE. Very light weight and cuts like butter
No where near messy as MDF

I think I have used something similar to what you are talking about ... also we have a product here called Nema board - I am not sure what the broader product name might be but it produces an excellent finish, cuts well and has a nice off white colour similar to the "clay" digital renderings many do from their CAD models.
