See for me this is a good thing to “keep in my back pocket” as I am gonna be building a cnc machine shortly and one of the projects I want to do is a instrument case made with hard wood and as I’m sure you know hard wood is expensive as all get out so being able to test with foam just to make sure the size is right and the file isn’t doing anything crazy is a great insurance policy, I’d rather mess up 20-50$ in foam then 300-500$ of hard to find wood
sound great. do u recommend a brand not so complicated, less than $5k, like 2ft x 3ft top? that cuts wood, styrofoam acrylic and more. I'm new in this and love the results. Thanks.
good to know. I need to refine the paths or something I was left with considerable areas that did not machine all the way down to the bottom. In Fusion 360 I would have done a final pass around the perimeter, but I didn't see how to do it in vcarve.
just the blue insulation boards you can buy at big box stores like lowes and home depot. It is really soft though, so if you wanted your stuff to last you'd need to coat it in bondo or something.
Thnaks for the reply! i want to start using the cnc to make fiberglass molds for my automotive designs , i pretty much need to carve into something really soft to cut and tobe able to leave a smooth finish to make a FG mold off it,, any ideas?
depends on your budget. This stuff could work if you have more time than money. You'd need to coat it and sand it. Others use a thicker foam that is for making molds but it is more expensive. It can be sanded smooth though.
which product are you asking about? The router is from cncrouterparts.com, the foam is blue foam insulation board from a home repair store like lowes or home depot. This sculpture isn't for sale (too low quality) but you want something done you can message me.
I doubt it. It is a good insulator, so by the time it got hot enough to bend on one side, the other would still be cold. Also cellular foams are delicate compared to sheets of solid Petg or ABS.
Thanks for posting this. Looking to do something similar. Build volume of 3D printing too small, print services WAY too expensive. CNCs for bigger way too big/expensive. Looks like industry's again offering Atari or mainframe. Groping, groping, groping for answers.
If your CNC has enough Z travel you could glue the foam into thicker blocks.

been playing with my XXL from Shapeoko, freaking love this thing!
@@bullswoodworks8398 I’m sure you do, I have to build though as I can’t afford a premade kit
Can you post what material that is and what mill bits were used?

What type of brocas do you use to cut foam?
is this CNC different machine that cuts wood like sign, letters or acrylic??
it is the same!

Trimming the edges with scissors works well.

Still that's probably your best 3D work so you are gaining ground fast.
which cutter did you use?
Great
nice!!! i got a cnc machine to start doing my prototypes too, it still not together.. what kind of insulation you are using there?

I think this is XPS
How can buy this product

Can this specific foam be used for thermoforming?
maybe if you coated it with something. As is, it would likely melt.
I doubt it. It is a good insulator, so by the time it got hot enough to bend on one side, the other would still be cold. Also cellular foams are delicate compared to sheets of solid Petg or ABS.
How long did it take to CNC this?
I don't think blue foam is EPS
what's the street value for this type of foam??
$20 for 4'x8' 2" thick.

Was this done from fusion 360?
