IMO, e.max full press molars way better than Zirconia. In many ways ....E.max softer material than Zirc , do not hit opposing. I made some emax crowns for my wife two years ago and loving it!
In our lab we make mostly e.max
What does everyone think of Titanium?

that guy took a baseball bat to the head. thats not some "porcelain failure".
wrong- lost this account due to the "not " porcelain failure and many other just like it- also loves to gas up from the sub structure- i will look to see if we have other bridges laying around
Out of random curiousity....also not a ceramicist....When you fire porcelain over titanium....Do you fire in an argon atmosphere? or vacuum?
at the time we were told to fire under vacum this was about 10 years ago not sure if it is still the same
from what i understand (doing a quick googling) Titanium surface finish must be 100% perfect before it is bonded to any substance (i.e. welding or other forms of fusion) else it runs the risk of "flaking"
if the picture above was a porcelain failure that could be your key. especially if you say it "gassed up" via the substructure.

yes you are correct - and perefect means perfect- very time consuming
i tired to upload pdf file - didnt work
After sandblasting, a resting time of 10 minutes in air is necessary to allow the surface oxide to form. Do not wait
for longer than 30 minutes before applying the bonder.
Important! Do not overheat the cast framework
during grinding. Avoid red heat and cool well with
water. Do not tilt the separating disk.
Doesnt necessarily have to be time consuming....blaster, etch in hydrofluric acid or comparable etchant....problem is...if you arent working in argon, or immediately applying a sealing agent....youve got 1-3 effective minutes before you are starting over again.
Never immerse titanium frameworks into hydrofluoric
acid as this severely corrodes titanium.Never immerse titanium frameworks into hydrofluoric

from tri-ceram pdf file
you also have to let frameworks sit for 10 minutes after blasting but only have up to and no exceeding 30 minutes to place bonder
