As some of you have pointed out, copper isn't the best choice for trivets. I like the look of copper and thought these would look interesting looking regardless of whether they work as well as they should or not. Also, we have granite countertops so heat transfer to the countertops is a non issue. I'm still going to make some feet for them though. Thank you all for watching! 🍻

Little pieces of felt glued under the feet will be sufficient. So you avoid scratches, too.

I guess they have a large thermal mass so this may not be an issue, but being a conductor of heat is the opposite of what you want from a trivit. It's supposed to isolate the surface from heat to protect from damage. I would replace or cover the feet with rubber.

Copper will suck the heat out of your pan/meal. And transfer the heat quickly to the surface you are trying to prevent heat getting transferred too. It'd be cool to add some rubber feet (those little sticky dots) to protect the surface you use it on. And maybe CNC/Laser cut out a thin piece of cork sheet to adhere to the top to make it as functional as it is beautiful. You could pocket out some shapes on the top surface to inlay with cork or do a trace of the entire shape, anything to prevent direct contact of the pan with the copper.

I've seen some king of random videos. Your right I believe he did a lot of open mold foam casts. I do mostly closed mold foam casts. For copper you would need a thicker shell. Copper is too heavy and would bleed out into the sand.

I would personally print some 'caps' for the feet in TPU (I think that's the 'rubbery' 3d-print material) so that my counter and table won't get scratched when I use them :)

Couldn't agree more on the use of "overture pla filament" That's the best PLA I've worked with.

Continuing the kitchen theme, it would be interesting if you would try forming some copper cookware (perhaps a sauté pan), and line it with tin.

Uhm, isn't the point of a trivet to keep a pot/pan's heat isolated from a (table) surface, both to keep the pot/pan hot, and protect the surface? Wouldn't making them from the _very_ heat-conductive copper be somewhat counter-productive to that point?

As usual, your work is nothing short of exquisite, but I think these trivets might be my favorite item you've cast!! Simply gorgeous pieces of functional art!

How many uses of the petrobond do you usually get before needing to replace it?

Im not sure copper is the right material for this since it is very conductive. If you want to use it anyways the trivit probably isolates better if you keep the feet on the upside to minimize the amount of heat transferred from the kettle into the trivit and spread the heat your desk will have to deal with onto a bigger surface.

Cool, but they are going to cool down the food you put on top really fast. Copper has better heat conductivity than Aluminium, 398 W/m•K vs 247 W/m•K, whereas a cast iron trivet will just have 60 W/m•K, and a stainless (304) is just about 20W/m•K

What's the purpose of a draft angle when using petrobond? A draft angle is for removing from a solid reusable mold.

nice build but why multi part set up?

If you want to eliminate the shrinkage dips in the t sections of your casting you can "chill" those areas by placing steel blocks on those areas when moulding. When the liquid metal hits the chilled faces it will freeze of and stop the shrinkage.

If you were assuming people generally know what trivets are, I suspect you were incorrect in that assumption.

why didn't you mesh the gears to see if they would be doing their thing? and figure out to what degree they would "scrape". be a lot cooler if you did

why not just use aluminium? It would have been cheaper + less heat conductive than copper. The copper will even help cooling down the pan more quickly, storing all the energy.

Oh, I normaly call those "things to put hot stuff on so you don't burn the god damned counter"

isn't solid copper the opposite of what you want for a trivet? you want something that is super fibrous like pressed paper fibers. Basically, you want asbestos pressed into that shape you've made. Obviously you don't literally want to use asbestos, but you want something with all the same properties (minus the whole cancer thing). Buck Knives sells a recycled pressed fiber cutting board that works great for this, and it has a nice knife that slides into the bottom

Love the stuff you usually make but this is the most stupid idea ever. Sure I might be usubke sometimes but you need a poor heat conductor for that task, not a copper one..
