New head

Are there any plans to produce a dual material head to use the abrasive filament with build support material so, ruby tip and normal tip.

There are some benefits to filled materials but not many use cases which cannot be met with the existing heads. What is your intended use?

I would like to see the same thing. It is entirely possible to develop the head that you are asking for by my understanding, there just needs to be enough demand to justify the development cost.

I design and kit large scale gliders for RC.  The carbon loaded filament so far has proved to be very strong and durable.  I would however like to be able to use soluble filament for support material in some of my builds as using the carbon filament is a waste and expensive.

A dual abrasive head is possible but not currently planned. The Needle valves make the DM head work so well for DM prints, avoiding strings and dribble while allowing very fast material changes during the print. The current design of the Olsson nozzle does not allow use of needle valves.

The next head we intend to release is a high temperature head based around a special nozzle from Olsson and our own heater block. This will allow high temperature materials such as Ultem and PEEK to be run through existing Robox units simply by changing the head.

I have not tried the PA12 Nylon but I must say the the results I am getting with the carbon fill is pretty damn good!  And the strength of the part produced is excellent.

Doesn't really matter what low cost material is used for support, at the moment there is no choice other than to use the carbon material as the support which is not very cost effective.
