Yes, we are also disappointed to delay multi-material, but in order to ensure a highly reliable experience, we need to give it some more time. We believe that while multi-material is a highly hyped feature user will much more frequently benefit from reliable printing of materials that require an enclosure and higher temps. Also the ability to print high resolution with smaller nozzle sizes we believe will be very powerful as well.
We will continue to work on multi-material, and when we are more confident in its reliability/repeatability across multiple machines and after the launch of the Nautilus single material, we plan to send units out to our beta testers. Until then we have more than enough to keep us busy testing hard to print materials with single material.
I'm personally pretty excited to see if e3d nozzle X lives up to the hype.
probably both Keith and I are very excited about the nozzle X i have plenty of carbon fiber pla to run and plan to get some PA-CF to also try high temp versions.
