Hi Sanat,

The Connex can be loaded with two different materials. The base color options are white, blue, grey, black, and a transparent amber. It can then mix and match different shades of the two materials loaded. So if you have white and black loaded, for example, you can then produce white, black, and a plethora of shades of grey on the same part. So while it can make different colors on the part, you're limited to whatever colors can be produced by mixing the two materials loaded. The more common use of the Connex is to utilize different types of materials (such as hard materials and soft materials) on one part to simulate over-molding, but it is often used with two rigid materials to simply show different colors.

You can watch the machine and learn about it here:<>

Hope this helps.

As I figure out, ZPrinters produce color by having full color (24 bit) in the binder that comes out from the inkjet. How is it achieved in Objet? The Connex family is basically a muti-material system with 8 print heads (as I make out four different materials at a time) and 96 nozzles per print head. Is the Connex family multi color or full color? How do they achieve color - Is it that two of the eight print heads responsible for a particular material print colored ink.

Just trying to understand the systems w.r.t color RP and how do the two technologies compare.

Thanking you.

RE: [rp-ml] color RP


There really are no other technologies that produce Multi colour in one pass. Apart from Objet/Zcorp.
There are other machies that are able to have different colours put in them at one time. However, you can also use various techniques by switching the material while the model is building to have a different colour. For example if you are building a bottle and you want the cap to be a different colour, you can switch the colour once the part reaches that building point.
Hope that helps!

Dear all,

I would like to know about the various color RP systems available. Z Printers by Z Corp is one which can produce color parts using their 3D Printing technology. Objet has a family of machines which can produce multi-material part and possibly in multi color using their polyjet technology. I would like to know about other existing technologies and their applications.

Thanking you.
