How to Make a Concrete Firepit With a 3D Printer
Ben Uyeda casts just three repeating shapes
By Rain Noe - Dec 03
There's something charming about creating your own fire pit or fire ring with pre-cut blocks or natural stone:

Also note that you don't need a 3D printer to do this; as Uyeda points out, you can form or carve your own shapes out of whatever material you have handy, then make a mold from those. But if you do want to go the 3D-printed route, Uyeda's made the 3D files available for free here.

Don't use a soft, tin cure silicone for concrete if you want your molds to last a dozen castings, kids. You also probably need less than half that much material if you make your mold boxes the same rough shape as the individual diamonds instead of one giant ass rectangle full of negative space.
And if you're already going to order big tubs of Smooth-On products, just add a pack of XTC-3D to the shipment and save yourself the headache of Bondo.!Report as spam -
This seems to be more of a fire decoration than a fire pit. It's not even a pit. Apart from aesthetically maybe being pleasing, I don't get what putting 37 decorative pieces around a fire gets you that is superior to a true fire pit. I think someone just wanted to make something.

Autodesk and Kickstarter Develop a Free, Downloadable Universal Test Print for 3D Printers
This allows you to evaluate what the machine can really do before you buy it
Before buying one, how do you determine if any given FDM (fused deposition modeling) 3D printer will be able to do what you need it to? Shouldn't there be some universal test print, like those printer test pages that you can use to determine if your printer's up to snuff?
