Found a source for color core (two color) HDPE sheet for exterior signage on Amazon that I have had good luck with. Nice range of colors, thicknesses, and sizes. I bought 1/4" material from them last spring to create labels for raised beds in a community garden. This stuff machines beautifully and should last a very long time. Also CNC’d some washers/bushings from it for exterior gate hinges - they open much smoother now. 🙂 Joe > **[Amazon.com: BuyPlastic King ColorCore Plastic Sheet 1/2" x 12" x 12" Arctic...](https://www.amazon.com/ColorCore-Plastic-Sheet-Choose-Thickness/dp/B08PW5CPPF?tag=benmyers-20)** > > Amazon.com: BuyPlastic King ColorCore Plastic Sheet 1/2" x 12" x 12" Arctic White-Black-Artic White Color Core, HDPE Board, High Density Polyethylene Panel : Industrial & Scientific ![HDPE Labels - 1](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/2X/1/1a7d5cc0aadfb0ccee2e66794732a653bdc11933.jpeg) ![HDPE Labels - 2](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/2X/a/afa31efcabf4c4cc7d54c687f2fc5ce4a9311365.jpeg) ![Raised Bed Label - 1](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/2X/6/6003a64b171068f37b48aa8778c77e598a1e91aa.jpeg) ![Raised Bed Label - 2](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/7/9/7996fe4df8ed424e1241e0e59c071eb5dcc24447.jpeg) ![Gate Hinge Bushing](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/2X/3/38bacbdc72fcc7705c36a16f987ff09bea425f12.jpeg) ---

Nice, I didn’t realize Amazon had any suppliers for this. I usually get mine from Inventables, they have a decent selection. Just for comparison, I found that buying 1 pc. of 1/4" x 12" x12" on Amazon was slightly cheaper than Inventables due to shipping cost, but buying qty. of 2+ was cheaper at Inventables. Amazon price is $23.38 for 1 pc. with “free” shipping Inventables is $9.97 for 1 pc, with shipping for 1 pc. @ $15.63 Adding additional pcs. only slightly increments the shipping cost. > **[HDPE | Inventables](https://www.inventables.com/categories/materials/plastic/hdpe)** > > Find innovative HDPE products for design, art, and prototyping. ---

My day job uses dozens of colorcore sheets every month, so I’ve got access to tons of offcuts. Almost all of it is 1/2" and 3/4" black/white/black. The catch is that the typical offcut is a strip from 2" to 3" wide. Let me know if you need some! ---

Dan Stein 2979 Judith Drive Bellmore,. NY 11710 Am I correct that Colorcore (3 layer 2 color) comes for CNC and for Laser? If correct Laserable material can also be used in CNC but Not Necessarily the reverse., This because you are limited as to what you can cut/engrave (Vaporize) with a laser. If you can, I would appreciate 1/8 and 3/16 or 1/4 Thank you so much!!! ---

Colorcore that we use is either 1/2" or 3/4", so that’s all I’ve got. I’ve never lasered HDPE so I can’t tell you how that’s going to work. Machines great, though. We use an O flute upcut bit typically. ---

Just tried the colorcore for the first time yesterday to make a dog-related street sign and it worked great. The bit was a 1/8" O-flute. To break the edges I used a 45 degree wood bevel bit running at about double the chip load for wood. ![Print Screen-011](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/9/3/931dae22fd43766128e128903ff821549e1d1204.jpeg) ![IMG_4114 Large](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/f/3/f316fca67f3c1c98a5f140e6651a05958caee127.jpeg) ---

I was just looking up your company! Look up my laser company [http://premierdisplayinc.com](http://premierdisplayinc.com) If I can return the favor with acrylic let me know. I am looking for colorcore 1/8 3/13/1/4… This for house signage It is more expensive than the acrylic I buy. Your samples are appreciated. Is seems waxier (Polypropylene I expect). I am a boater as well so I see applications for doors etc. I see products on your wall on your website that seem to use this material. Do you have cutoffs? Thanks Again! ---

The best price I’ve found for King ColorCore is Cutting It Close. They carry 6 of the more popular colors. 1/2" 12x24 is only @29.99, and 1/4" 12x24 is only $14.99. Free shipping on orders over $150.
