What is the ultimaker 2 frame made out of?

[nathan-peterson 0]

The front panel on the ultimaker 2 appears to be a wood panel sandwiched between two sheets of aluminum. I am working on a project that this type of material would work well for. Where can I get this? Also what is the best way to cut this? CNC milling machine?

It's polyethylene sandwiched between aluminum panels. The material is called Dibond, and is commonly used in the sign-making industry.

And yes, it is typically cut by milling it, although it can be sawed as well I think.

Awesome thanks! I found a distributer locally. I'm going to go check them out tomorrow. The guy that I talked to on the phone said that I can even use a CNC router instead of a CNC milling machine. Very cool!

How is a cnc router different from a cnc milling machine? As far as google tells me, it's the same thing.

A router is typically a 2.5D machine while a mill is 3D...

A router is more lightweight -- it is what most hobbyists have.

Be sure to use a angled bit to finish the edges of Dibond. The aluminum is sharp at 90 degree angles. Our first 10 prototypes where just straight cuts with no deburring. We bled a lot because of those machines.

Well, most of the scars are gone now

I'm not an expert, but my understanding is that milling machines are generally used for metal, because they are more heavy duty, and routers are generally used for softer materials like wood or acrylic. I have access to both with my Techshop membership. The router is a lot easier to use and can handle much larger items, but we are not allowed to use metal on it.

Thanks for the tip about that angled bit! That will probably save me some bloody fingers.

the physical ones are

Some scars will never heal :(

Do you use the angled bit on both sides to clean up the edges? If so, how do you line it up accurately in the CNC machine after flipping it over?

 

[nallath 1,124]

Yeah, both ends are angled. I have no idea how it's done, this is one of the things we don't do ourselves.

 

[amedee 349]

how do you line it up accurately in the CNC machine after flipping it over?

 

Easiest is to first cut a template in cheap wood that you then use as frame to position your plate.

Or use a router bit with a roller guide on the end. Then just follow the edge of the board.

Utilisez-vous le peu inclinée sur les deux côtés pour nettoyer les bords? Si oui, comment avez-vous alignez-le avec précision dans la machine CNC en faisant un tonneau?

^ Took me some time to realize that previous post is actually a Google Translate to French from post #12

(And Google is doing a pretty bad job, as it is really hard to understand the French version...)

Not sure what the purpose is though...
